    _________________________________
    In 2009, law-enforcement officials began investigating a Mexican cocaine-
    trafficking operation extending into the Kansas City area. This led them to several
    suspects, including Marvin Ellis, a low-level powder-cocaine buyer, who was
    working with two others to buy powder cocaine and cook at least some of it into
    cocaine base (crack cocaine) for resale. In 2012, Kansas police arrested Ellis after he
    fled from a traffic stop. At arrest, Ellis had a stolen handgun, miscellaneous drugs,
    and some drug-dealer paraphernalia. Later, based on this and separate evidence from
    the federal investigation, a federal grand jury charged Ellis with several drug and
    firearm felonies. The most serious charge against Ellis was for his conspiring with 49
    other persons to manufacture, distribute, or possess with the intent to distribute at
    least 5 kilograms of powder cocaine and 280 grams of crack cocaine.
    After the jury convicted Ellis on all charges, the district court imposed
    consecutive sentences for the cocaine-conspiracy count and a firearm count and
    concurrent sentences for the remaining counts. Ellis received a sentence of life
    without release on the cocaine-conspiracy count (after applying a sentencing
    enhancement under 21 U.S.C. § 851 for his two earlier felony-drug-offense
    convictions), a mandatory-minimum five-year term for possession of a firearm in
    furtherance of a drug-trafficking crime under § 924(c), and statutory maximum
    sentences on all remaining counts. Later, the district court revoked Ellis’s supervised
    2
    release from a 2007 federal conviction and sentenced him to an additional
    consecutive 24 months’ imprisonment.
    Ellis now appeals some of his convictions and sentences. In Appeal No. 14-
    3165, Ellis (1) challenges his convictions under 21 U.S.C. §§ 846, 841(a)(1),
    (b)(1)(A), 18 U.S.C. § 924(c), and 21 U.S.C. § 856; (2) argues that his life sentence
    for the conspiracy conviction violates the Fifth and Sixth Amendments; and (3)
    argues that the district court violated his Sixth Amendment right to counsel at
    sentencing. In Appeal No. 14-3181, Ellis challenges the consecutive sentence for his
    supervised-release violation, based on the district court’s denying him substitute
    counsel.
    In Appeal No. 14-3165, we affirm all of Ellis’s convictions and all of his
    sentences except one. Though we affirm Ellis’s cocaine-conspiracy conviction, we
    reverse its accompanying life-without-release sentence because (1) the jury never
    found that Ellis was individually responsible for the charged amounts of powder or
    crack cocaine, either from his own acts or the reasonably foreseeable acts of his
    coconspirators; and (2) the government’s evidence does not show that omitting this
    element was harmless beyond a reasonable doubt. In Appeal No. 14-3181, we affirm
    Ellis’s sentence for violating his supervised release. We remand to the district court
    for a full resentencing, subject to resentencing on the cocaine-conspiracy count under
    21 U.S.C. § 841(b)(1)(C).

    BACKGROUND
    I.     The Investigation
    In 2009, Drug Enforcement Administration (DEA) agents began investigating
    a Mexican cocaine-trafficking network that was supplying the Kansas City area.
    Agents learned that Mexican drug sources were shipping multi-kilogram deliveries of
    powder cocaine from Mexico into and near Kansas City. In addition, agents learned
    that some of this powder cocaine was going to local drug dealers, including Djuane
    Sykes, who was selling large amounts of cocaine to several customers from the 2200
    block of Russell Avenue in Kansas City, Kansas.
    Among Sykes’s many customers were Ataven Tatum and Marvin Ellis. In
    August 2011, Ellis had been released from prison to supervised release after serving
    time on a 2007 conviction for violating 18 U.S.C. § 924(c). By November 2007, Ellis
    had begun working with Tatum and Ellis’s nephew, Theoplis Ellis (Theoplis), to buy
    powder cocaine from Sykes and cook at least some of it into crack cocaine for sale to
    their customers. Over the next few months, the three men worked together to sell
    drugs, including crack cocaine. They sold the drugs from different locations,
    including from a house at 921 Haskell Avenue. In October 2011, Ellis leased this
    residence, and in November, Tatum signed a contract for deed to buy it.
    II.    Ellis’s Arrest
    In late April 2012, a Kansas City, Kansas police officer, Patrick Locke,
    stopped Ellis for a traffic violation. After first pulling over to the roadside, Ellis sped
    4
    away when Office Locke’s partner approached the car. Officer Locke gave chase
    until Ellis crossed the Kansas state line into Missouri.
    Two weeks later, just after midnight on May 11, Officer Locke again stopped
    Ellis for a traffic violation. As before, Ellis pulled over but then sped away. Again,
    Officer Locke chased Ellis, this time at speeds up to 80 miles per hour. The chase
    ended when Ellis lost control of his car after it hit a curb. When his car came to rest,
    Ellis jumped from it and ran. During the ensuing foot chase, Officer Locke saw that
    Ellis was carrying a green plastic bag. When Ellis was subdued on the ground,
    Officer Locke saw Ellis holding his right hand in his waistband—causing Officer
    Locke to fear that Ellis had a gun. Officer Locke tasered Ellis, yet Ellis refused
    commands to remove his hand from his waistband. When Officer Locke threatened to
    shoot Ellis, Ellis dropped the green bag and threw a pistol about 10 to 15 feet away.
    After finally subduing and arresting Ellis, Officer Locke gathered Ellis’s
    thrown gun—a stolen, loaded .40 caliber pistol. Officer Locke also collected Ellis’s
    discarded green bag, which contained an empty sandwich-bag box, a digital scale, 2.5
    grams of powder cocaine, about 32 grams of synthetic marijuana, 25.8 grams of PCP
    in a bottle, 3.1 grams of marijuana, 16 mollies (ecstasy/MDMA), and 8 Diazepam
    pills.
    III.     The Charges
    In October 2012, a grand jury sitting in the District of Kansas issued a
    sweeping 112-count Second Superseding Indictment against 51 defendants, including
    5
    Ellis, Tatum, and Theoplis.1 In a vast cocaine-conspiracy count under 21 U.S.C. §
    846, naming 50 defendants including Ellis (reaching all the way up to the Mexican
    cartel), the grand jury charged that the 50 defendants
    [k]nowingly and intentionally conspired and agreed together and with
    each other, and with other persons known and unknown to the Grand
    Jury, to commit the following offenses against the United States: to
    manufacture, to possess with intent to distribute and to distribute 280
    grams or more of cocaine base, “crack,” a controlled substance; and to
    possess with intent to distribute and to distribute five kilograms or more
    of a mixture and substance containing cocaine, a controlled substance;
    all in violation of Title 21, United States Code, Sections 841(a)(1),
    (b)(1)(A)(ii), (b)(1)(A)(iii) and Title 18, United States Code, Section 2.
    R. vol. I (3165) at 547.
    Eight months after filing the Second Superseding Indictment, the government
    filed an Information under 21 U.S.C. § 851 to enhance Ellis’s sentence. Because Ellis
    had two earlier convictions for felony drug offenses, the § 851 Information subjected
    him to an increased mandatory sentence—life without release—if he was convicted
    and sentenced for the conspiracy charge under 21 U.S.C. §§ 846 and 841(a)(1),
    (b)(1)(A).2
    The Second Superseding Indictment also charged Ellis with six counts of
    knowingly and intentionally distributing crack cocaine, in violation of 21 U.S.C. §
    1
    The Second Superseding Indictment charged additional defendants in the
    conspiracy count. The conspiracy count included Ellis each time, and the substance
    of the charge remained the same.
    2
    The government listed two state felony drug convictions necessary to trigger
    the enhancement: one for felony possession of cocaine in 1997, and another for
    selling cocaine in 2003.
    6
    841(a)(1) and (b)(1)(C), and aiding and abetting those offenses, in violation of 18
    U.S.C. § 2; one count of maintaining a drug-involved premises, in violation of 21
    U.S.C. § 856(a)(1)–(2); one count of knowingly and unlawfully possessing a firearm
    in furtherance of a drug-trafficking crime, in violation of 18 U.S.C. § 924(c); and one
    count of possessing a firearm as a felon, in violation of 18 U.S.C. §§ 922(g)(1) and
    924(e).
    IV.   Trial
    Ellis was tried with several coconspirators, some of whom pleaded guilty
    during the trial. In the end, Ellis proceeded to a jury verdict with three others: Robert
    Vasquez, Vernon Brown, and Kyle Stephen.
    A.      Conspiracy Evidence
    The government sought to prove the cocaine-conspiracy count against Ellis by
    the testimony of several witnesses, including three cooperating witnesses, four law-
    enforcement officers who had arranged the controlled buys of crack cocaine from
    Ellis and Tatum, and other law-enforcement officers who had participated in the
    investigation.
    One government witness, Djuane Sykes, testified that he knew Ellis, Ataven
    Tatum, and Theoplis. Sykes said that in late 2011, Ellis and Tatum approached him to
    buy powder cocaine for resale. At this meeting, Sykes sold Ellis an ounce of cocaine
    for $700. Sykes also testified that Ellis—either for himself or for Tatum—continued
    to buy powder cocaine from him. Sykes said that Ellis sometimes bought half or full
    ounces of powder cocaine. Sykes never said how many times Ellis alone had bought
    7
    powder cocaine from him. But Sykes did say that Ellis, when with Tatum, had bought
    powder cocaine from him “[m]aybe ten or 15 times.” R. vol. IV (3165) at 1590. Each
    time, Ellis bought between a “half-ounce to a [sic] ounce of cocaine.” 
    Id. at 1589.
    In
    addition, Sykes said that Tatum bought a “half-ounce to three ounces” of powder
    cocaine from him “once or twice a week.” R. vol. IV (3165) at 1587. Sykes also said
    that Tatum sent Ellis or Theoplis to pick up cocaine “[p]robably four or five times.”
    
    Id. at 1590.
    Another government witness, Ralph Mayo, was a local drug dealer who
    confirmed that Ellis, Tatum, and Theoplis had bought powder cocaine from Sykes.
    Mayo testified that he had seen Ellis “a few times” buying cocaine from Sykes. R.
    vol. V (3165) at 1233. In addition, Mayo testified that Mayo had sold “probably
    between a [sic] ounce or two ounces” of powder cocaine to Ellis “[p]robably not
    more than two times.” Id.at 1234–35.
    A third government witness, Theoplis, testified about his drug activities with
    Ellis and Tatum. Theoplis recalled once going with Ellis to buy powder cocaine from
    Sykes. In addition, Theoplis recalled that Tatum and Ellis had sent him to Sykes “two
    or three times” to pick up powder cocaine. 
    Id. at 677.
    Though Theoplis did not say
    how much cocaine he bought during his solo trips or during his single trip with Ellis,
    he did say that he picked up “three and a half ounces, four” when Tatum and Ellis
    sent him to Sykes. 
    Id. at 6776.
    Theoplis also testified that Tatum and Ellis cooked the powder cocaine into
    crack cocaine. The prosecutor asked, “once the powder cocaine was purchased, was it
    8
    always cooked into crack cocaine?” Theoplis answered, “Yes, ma’am.” 
    Id. at 678.
    He
    further testified that after Tatum and Ellis bought powder cocaine from Sykes, they
    would “go back and cook the crack and cook the soft to hard.” 
    Id. at 673–74.
    But on
    cross-examination by Ellis’s attorney, Theoplis admitted that he had seen Ellis cook
    crack cocaine just once, at Theoplis’s father’s house. Theoplis also answered
    affirmatively to the prosecutor’s question asking him if he, Tatum, and Ellis had sold
    only crack cocaine and not powder cocaine. Theoplis never said how many times he
    sold crack cocaine, but he did say he sold “pieces” for ten or twenty dollars. 
    Id. at 683.
    The government called Kansas City police officer Nathan Doleshal to testify
    about the controlled buys he had arranged in which informants bought crack cocaine
    from Ellis, Tatum, and Theoplis3 at 921 Haskell and elsewhere.4 During the
    controlled buys, an informant typically called Tatum or Ellis to arrange the buy and
    then bought the crack cocaine from either one or both of them. During the first
    controlled buy, on February 7, 2012, an informant bought 0.9 grams of crack cocaine
    from Ellis at 921 Haskell. The next day, the same informant bought another 0.7
    grams of crack cocaine from Ellis and Tatum at 921 Haskell. On February 9, an
    informant bought 2.5 grams of crack cocaine from Ellis and Tatum, this time at a
    local grocery store. On February 10, informants bought 9.9 more grams of crack
    3
    Theoplis usually acted as a “doorman,” letting the informant-buyers into the
    house and taking them to Ellis and Tatum. R. vol. II (3165) at 119.
    4
    The record is unclear about the participants in and locations of some
    controlled buys.
    9
    cocaine, this time purchased at an intersection and later another 1.2 grams of crack,
    this time at 921 Haskell.
    Law-enforcement officers also testified about more controlled buys in March
    2012. On March 20, 2012, at a local pharmacy, an informant bought 3.4 grams of
    crack cocaine from Ellis. On March 23, at a local street intersection, an informant
    bought 6.7 grams of crack cocaine and some ecstasy pills from Ellis. All told, the
    controlled buys totaled 25.3 grams of crack cocaine.5
    B.     Evidence of Drug-Involved Premises
    The government produced evidence that Ellis had maintained 921 Haskell as a
    place for manufacturing and selling crack cocaine. Although not specifying dates,
    Theoplis testified that Ellis had lived at 921 Haskell and sold crack cocaine, ecstasy,
    PCP, and marijuana there. Three of the controlled buys from Ellis happened at 921
    Haskell, the last occurring on February 10, 2012. The government also produced
    wiretapped phone calls (some in March and April 2012) in which Ellis, Tatum, and
    Theoplis arranged crack-cocaine sales, and one call in which “[t]his young lady’s
    [sic] called Ataven [Tatum] to pretty much tell her [sic] that Messy or Marvin Ellis
    was wanting some supplies to cook crack cocaine.” See R. vol. III (3165) at 2270-88.
    In particular, Ellis supposedly was seeking a whisk to “blend the ingredients
    together.” 
    Id. at 2270.
    5
    The record is unclear why the officers stopped the controlled buys so close to
    28 total grams of crack cocaine, which would have activated a mandatory-minimum
    sentence under 21 U.S.C. §§ 851, 841(a)(1), (b)(1)(B).
    10
    The evidence further showed that in October 2011, Ellis signed a lease
    agreement for 921 Haskell. The lease required Ellis to pay a $300 deposit and $600
    for the first month’s rent. Of this amount, Ellis paid $400, and Tatum paid $500. The
    next month, Tatum signed a contract for deed to buy the residence. When police
    officers searched 921 Haskell on May 30, 2012, they found a utility bill for service
    from April 13 to May 14, 2012, in Ellis’s name. Though police had arranged
    controlled buys at 921 Haskell during this billing period, Ellis was not present for
    them—he had left the house after a falling out with Tatum. In an intercepted phone
    call on April 12, a caller asked Tatum “how Marvin Ellis is doing,” and Tatum
    responded that he had put Ellis out of the house. R. vol. III (3165) at 2287.
    C.     Evidence of Firearm Possession in Furtherance of Drug Trafficking
    Officer Locke testified that at the arrest, Ellis had a stolen, loaded .40 caliber
    pistol, along with several kinds of illegal drugs, an empty sandwich-bag box, and a
    digital scale. Officer Locke testified that drug dealers use these items for drug sales.
    Theoplis testified that he had previously seen Ellis with this same pistol when selling
    drugs at 921 Haskell.
    D.     Jury Instructions and Verdict Form
    Before closing arguments, counsel met with the district judge about jury
    instructions and a verdict form. During this conference, the district court remarked
    that it had “e-mailed a draft copy of the verdict [form] to all of the counsel of
    record.” R. vol. V (3165) at 1452. The district court further mentioned that “the main
    feedback we got was that the verdict form should not include the drug amounts and I
    11
    think that feedback is correct. So we’ve prepared a revised verdict form which omits
    any reference to the drug quantities.” 
    Id. The district
    court did not identify which
    counsel had provided this feedback.6
    After this, the district court asked all counsel, “Is there any objection to the
    revised form of the verdict?” 
    Id. No one
    objected. In particular, Ellis’s counsel
    responded, “None on behalf of Mr. Ellis, Your Honor.” 
    Id. Thus, for
    the cocaine-
    conspiracy count, the final verdict form asked the jury to determine Ellis’s guilt only
    in the broad conspiracy and did not require the jury to say how much powder or crack
    cocaine it attributed (1) to the entire conspiracy or (2) to Ellis from his own acts and
    the reasonably foreseeable acts of his coconspirators.
    The jury instruction for the cocaine-conspiracy count listed the elements that
    “the government must prove beyond a reasonable doubt,” including one element
    requiring proof that “[t]he overall scope of the agreement involved more than 5
    kilograms of cocaine or more than 280 grams of cocaine base, ‘crack.’” R. vol. I
    (3165) at 1510. Another element required that “[w]hen defendant joined, he knew the
    essential objective of the agreement was to manufacture, to possess with intent to
    distribute or to distribute controlled substances in violation of federal drug laws[.]”
    
    Id. The next
    instruction stated that “[o]nce a person becomes a member of a
    conspiracy, he . . . is legally responsible for the acts of all other members in
    furtherance of the conspiracy, even if he . . . was not present or aware that the
    6
    The record does not reveal which of the multiple counsel submitted proposed
    verdict forms to the district court, let alone whether any of those included spaces for
    the jury to individually attribute cocaine amounts to each defendant.
    12
    specific acts were being committed.” 
    Id. at 1513.
    Ellis did not object to these
    instructions. No instruction addressed reasonable foreseeability.
    E.     Opening Statement and Closing Arguments
    In its opening statement and closing argument, the government argued Ellis’s
    guilt based largely on the acts of the Mexican cocaine sources, including those
    sources supplying powder cocaine to Sykes.
    For instance, in its opening statement, the government named Ellis as one of “a
    variety of individuals who were engaged in drug trafficking in the Kansas City
    metropolitan area,” and then stated that “Mexican cartels use these public roadways
    to have large amounts of drugs transported from Mexico into the United States by a
    variety of ways.” R. vol. III (3165) at 445. The government spoke about “trusted
    couriers based from cell heads” who were distributing drugs and “polluting our
    community.” 
    Id. at 445–46.
    It said that “[m]illions of dollars of drugs are coming in
    and millions of dollars of money are going out.” 
    Id. at 446.
    It tied small-time
    distributors of the cocaine—“street level dealers to mid-level dealers to large scale
    dealers”—to the cartel’s supply. 
    Id. And in
    its closing argument, the government returned to this theme, emphasizing
    the conspiracy-wide amounts of cocaine:
    And I assert to you that it’s not important that any particular defendant
    knew much at all about the overall scope of the conspiracy. It’s irrelevant
    that Marvin Ellis didn’t know a single Hispanic person on that chart.
    What’s important is that any reasonable person knows that drugs like
    cocaine come from a source. And it’s reasonable to conclude that the source
    would be a Hispanic source.
    13
    R. vol. V (3165) at 1475–76. For interdependence, the government asserted a relationship
    between Ellis and the cartel and its suppliers:
    The suppliers rely upon people like Robert Vasquez to make sure that they
    can keep up getting a supply. Without people like Robert Vasquez taking
    money loads back to the south, they’re [sic] aren’t going to be sending up
    anymore [sic] supply. And without customers like Kyle Stephen and
    Vernon Brown and Marvin Ellis, the suppliers aren’t going to have a
    business.
    
    Id. at 1476.
    In his closing argument, Ellis’s counsel tried to counter this by arguing that
    Ellis was a “very, very small minnow in a very large ocean and he is nowhere near at
    the level of the great white sharks that [the government] paraded through that witness
    stand.” 
    Id. at 1515.
    But in rebuttal, the government responded that “it doesn’t matter if you’re a
    little person, if you’re a bottom feeder, you’re still guilty of the conspiracy.” 
    Id. at 1558–59.
    The government stressed that it is “[p]eople like Marvin Ellis and Vernon
    Brown that keep people like Hector Aguilera in business.” 
    Id. at 1568.
    The
    government had earlier described Hector Aguilera as the “kingpin.” 
    Id. at 1482.
    It
    described the “scope of the overall conspiracy” as the quantities charged in the
    indictment, “[n]ot what each individual person was involved with.” 
    Id. at 1563.
    V.     Ellis’s Request for New Counsel
    While the probation office was completing its Presentence Investigation
    Report (PSR), Jay DeHardt, Ellis’s counsel, moved to withdraw. DeHardt told the
    district court that Ellis had refused to read the PSR and had demanded that DeHardt
    14
    no longer represent him. DeHardt told the court that Ellis had even accused him of
    conspiring with the government to convict him. In short, DeHardt said that Ellis
    refused to listen to him or cooperate.
    At a hearing on the motion, Ellis expressed his dissatisfaction with DeHardt’s
    trial performance, complaining that DeHardt had not challenged the length of time in
    which Ellis was involved in the conspiracy and had not separated him from the broad
    conspiracy. Ellis asked the district court to appoint new counsel. The district court
    denied Ellis’s request. The court acknowledged the breakdown of communication
    between Ellis and DeHardt but found Ellis responsible for “not reasonably trying to
    communicate” with DeHardt or to help DeHardt prepare a defense. R. vol. V (3165)
    at 1613. With that, the district court granted DeHardt’s motion to withdraw.
    The district court then gave Ellis two options: he could hire a different
    attorney, or he could represent himself. The court strongly advised Ellis against self-
    representation and questioned Ellis’s decision to proceed pro se:
    Court:        Do you want to represent yourself or do you want to hire
    an attorney?
    Ellis:        I don’t have any money right now.
    Court:        Okay. Then your choice is to stay with Mr. DeHardt and
    work with him or represent yourself.
    Ellis:        He’s not working with me, Judge.
    Court:        That is—I heard all I need to hear about that. Do you want
    to stay with him and cooperate and help him represent you
    or do you want to represent yourself?
    Ellis:        I represent myself.
    15
    Court:        Okay. Then, Mr.—Do you want him to be available as
    stand-by counsel if you have questions?
    Ellis:        I hope he wish me the best.
    Court:        Do you want him to represent—to be available as stand-by
    counsel to answer any questions you may have?
    Ellis:        No, ma’am.
    Court:        Okay. Then, again, I think this is an incredibly poor
    decision on your part, but I find that you have voluntarily
    and knowingly given up your right to counsel in this case
    and I will let you represent yourself for the purposes of
    sentencing and appeal.
    
    Id. at 1629–30.
    Before the sentencing hearing, Ellis twice renewed his motion to appoint him
    new counsel. In response to the first motion, the district court reappointed DeHardt,
    who moved to withdraw a month after his reappointment. DeHardt told the court that
    his attorney-client relationship with Ellis was “beyond resurrection.” R. Vol. 1 at
    1547. At the sentencing hearing, the district court denied Ellis’s second motion
    because Ellis had failed to cooperate and because it believed that a newly appointed
    attorney would take months to become sufficiently acquainted with Ellis’s case.
    VI.   Sentencing
    Ellis represented himself at the sentencing hearing. He objected to several
    paragraphs in the PSR, most of which concerned the facts underlying his conviction.
    After hearing Ellis’s objections, the district court denied them. Ellis also objected to
    the sentence enhancement under 21 U.S.C. §§ 841(a)(1), (b)(1)(A) and 851. The
    district court rejected this argument too. Before the district court imposed a sentence,
    16
    Ellis reiterated his request that the court appoint him new counsel. The court declined
    to revisit that issue.
    On the cocaine-conspiracy count, the district court sentenced Ellis to life
    imprisonment without release—the sentence mandated by 21 U.S.C. §§ 846,
    841(a)(1), (b)(1)(A) and 851. In addition, the district court sentenced Ellis to the
    statutory maximum on all of his other convictions: 360 months for each of the six
    cocaine-possession and cocaine-distribution convictions, concurrent with each other
    and the life sentence; 240 months for the drug-involved-premises conviction,
    concurrent with the other sentences; and 120 months for the felon-in-possession-of-a-
    firearm conviction. Finally, the district court sentenced Ellis to the mandatory-
    minimum sentence of 60 months for the § 924(c) offense of possessing a firearm in
    furtherance of a drug-trafficking crime. Ellis timely appealed.
    VII. Revocation of Ellis’s Supervised Release
    Soon after the sentencing hearing, the district court held a hearing on the
    government’s motion to revoke Ellis’s supervised release imposed for his § 924(c)
    conviction in 2007. At this hearing, DeHardt represented Ellis, and Ellis again
    requested appointment of a different attorney. In response, the district court gave
    Ellis the same option it had given him at sentencing: he could proceed with DeHardt,
    or he could proceed pro se. Ellis elected to “go pro se.” R. vol. II (3181) at 17.
    Before the revocation hearing began, the district court questioned Ellis about (1) his
    legal experience, (2) the penalty he was facing if the court revoked supervised
    release, (3) his awareness that he would have no help during the hearing, and (4) his
    17
    knowledge that he could have DeHardt represent him at the hearing. The district
    court strongly urged Ellis “not to try to represent [himself].” 
    Id. at 21.
    Despite this,
    Ellis chose to represent himself, and the district court found that Ellis had “knowing
    [sic] and voluntarily given up [his] right” to counsel. 
    Id. Ellis did
    not contest that he had violated the terms of his supervised release.
    He asked only that the district court order any resulting prison sentence to run
    concurrently with his other sentences. Instead, the district court sentenced Ellis to a
    consecutive term of 24 months’ imprisonment to the sentences he received in Appeal
    No. 14-3165. Ellis has appealed his conviction and sentence for violating his
    supervised-release terms.
    DISCUSSION
    I.     Conspiracy Conviction
    A.      District-Court Proceedings
    As noted, the government charged Ellis and 49 other defendants in a broad
    cocaine-distribution conspiracy stretching from a Kansas City street corner to a drug
    cartel in Mexico. In its jury instructions, the district court did not tell the jury to
    determine what cocaine amounts were individually attributable to Ellis, by his own acts
    and the reasonably foreseeable acts of his coconspirators. And such an instruction would
    not have mattered anyway, because the district court did not furnish the jury a special-
    verdict form on which to enter those findings.
    Though the government offered some crack-cocaine evidence, it sought Ellis’s
    conviction primarily by arguing that he was necessarily responsible for the cocaine
    18
    kilograms trafficked into the area by the Mexican cartel. The government did so even
    though acknowledging that Ellis knew no one in the chain above his street supplier,
    Djuane Sykes. From its opening statement through its closing arguments, the government
    pressed a Mexican-cartel theme.
    With this general-verdict form, the jury found Ellis guilty by checking the space
    next to “guilty.” R. vol. I (3165) at 1483. As mentioned, the verdict form provided no
    spaces by which the jury could say what amount of cocaine powder or crack cocaine the
    entire conspiracy involved, and no spaces to say what amounts it attributed individually
    to Ellis. As seen, the jury instruction had an “in furtherance” requirement for
    coconspirator acts, but it lacked a reasonable-foreseeability requirement. 
    Id. at 1513.
    The
    general-verdict form underlies Ellis’s challenge to his conviction and sentence on the
    cocaine-conspiracy charge.
    B.     Ellis’s Contentions on Appeal
    1.     Sufficiency of the Evidence
    Ellis first asks us to vacate his conspiracy conviction. He contends that the
    government presented insufficient evidence “to establish that the possession, distribution,
    or manufacture of either 280 grams of crack cocaine or five kilograms of powder cocaine
    was reasonably foreseeable to Mr. Ellis.” Appellant’s Opening Br. at 16. Ellis argues that
    the district court erred in not requiring that the jury convict him for only the amounts it
    found reasonably foreseeable to him.7 And, further, Ellis argues that the jury lacked
    7
    A jury may include within a defendant’s individually attributable drug
    amounts the defendant’s own acts as well as his coconspirators’ reasonably
    19
    sufficient evidence to find that he conspired to possess, distribute, or manufacture either
    280 grams of crack cocaine8 or 5 kg of powder cocaine. Thus, Ellis argues, we must
    reverse his conviction.
    Ellis builds his sufficiency-of-the-evidence argument on a mistaken legal premise.
    He assumes that the jury could not convict him for the cocaine-conspiracy count absent
    its finding that the conspiracy involved at least 5 kilograms of powder cocaine or 280
    grams of crack cocaine. But to sustain his conspiracy conviction, the government needed
    to prove only that Ellis conspired “to manufacture, distribute, or dispense, or possess with
    intent to manufacture, distribute, or dispense” any amount of either substance. 21 U.S.C.
    §§ 841(a)(1); 846. And he certainly did so. So, at the very least, Ellis stands properly
    convicted under 21 U.S.C. § 841(a)(1), (b)(1)(C).9 See United States v. Cruse, 805 F.3d
    foreseeable acts in furtherance of the conspiracy. See United States v. Morales, 
    108 F.3d 1213
    , 1226 (10th Cir. 1997) (“Where the sentencing court determines a
    defendant was directly involved in the distribution of a quantity of drugs sufficient to
    invoke a mandatory minimum sentence under 21 U.S.C. § 841(b)(1)(A), the quantity
    of drugs reasonably foreseeable to the defendant is irrelevant.”).
    8
    The government has a much stronger case to support a sufficiency-of-the-
    evidence argument for the crack cocaine. The crack-cocaine amount rests not on
    Mexican-cartel liability but instead on the crack cooking and sales by Ellis, Tatum,
    and Theoplis. But we need not decide whether sufficient evidence exists or not. The
    government failed to obtain a jury finding that 280 grams of crack cocaine were
    individually attributable to Ellis, so it must show the resulting error under Alleyne v.
    United States, 
    133 S. Ct. 2151
    , 2155 (2013), was harmless beyond a reasonable
    doubt.
    9
    This also disposes of Ellis’s alternative argument that even if sufficient
    evidence supported his conviction (for conspiring to distribute and manufacture at
    least 5 kilograms of powder cocaine and 280 grams of crack cocaine), the jury may
    have convicted not on the sufficient evidence of those amounts individually
    20
    795, 817 (7th Cir. 2015) (concluding that “drug quantity is not an element of a drug
    conspiracy under § 841(a)(1)”); United States v. Daniels, 
    723 F.3d 562
    , 572 (5th Cir.
    2013) (concluding that the government’s failure to prove 5 kilograms of powder cocaine
    affected the sentence but did not undermine the conviction); United States v. Collins, 
    415 F.3d 304
    , 314 (4th Cir. 2005) (concluding that conviction under 21 U.S.C. § 846 was
    sound despite the government’s failure to prove the charged amount of crack cocaine);
    United States v. Vazquez, 
    271 F.3d 93
    , 105 (3d Cir. 2001) (en banc) (concluding that for
    an indictment charging 5 kilograms of powder cocaine, courts may sentence for a lesser-
    included offense when the government’s proof doesn’t support that weight).10
    2.     Sixth Amendment: Alleyne
    On appeal, Ellis contends that the district court violated his “Sixth Amendment
    rights by imposing a life sentence on the conspiracy count without a required factual
    finding by the jury—that it was reasonably foreseeable to Mr. Ellis that other
    members of the charge [sic] conspiracy would distribute more than 280 grams of
    cocaine base and five kilograms of cocaine.” Appellant’s Opening Br. at 17–18. Ellis
    argues that the district court erred by sentencing him under § 841(a)(1), (b)(1)(A)
    without obtaining the jury’s findings of the weight of powder and crack cocaine
    reasonably foreseeable to him.
    attributable to him, but instead on amounts that were not individually attributable to
    him.
    10
    See also United States v. Cernobyl, 
    255 F.3d 1215
    , 1218 (10th Cir. 2001)
    (“Federal courts have historically construed the provisions of § 841(a) as the
    substantive elements of the offense . . . .”).
    21
    The government argues that Ellis waived this issue by inviting any error in the
    verdict form. So we must examine how the verdict form was proposed and approved.
    We note that the district court told counsel at the jury-instruction conference that “the
    main feedback” it had received after e-mailing a verdict form with spaces for the jury
    to find cocaine amounts attributable to individual defendants was that the verdict
    form should not leave spaces for the jury to make those findings. R. vol. V (3165) at
    1452. The district court mistakenly agreed that this feedback correctly stated the law.
    So the district court advised that it had “prepared a revised verdict form which omits
    any reference to the drug quantities.” 
    Id. Based on
    this discussion, the government
    contends that Ellis rejected the original verdict form with spaces for the jury to make
    cocaine-quantity findings, thus waiving appellate review of the verdict form.
    We disagree with the government’s position. We note that after the district
    court asked counsel if any party objected to the verdict form, Ellis’s counsel simply
    responded, “None on behalf of Mr. Ellis, Your Honor.” 
    Id. By declining
    to object, a
    defendant does not knowingly waive an error. Nothing shows that Ellis’s counsel
    even provided “feedback” about the verdict form. 
    Id. We see
    nothing showing that
    Ellis’s counsel proffered a verdict form without drug quantities to the district court or
    persuaded the district court to adopt one like that. See United States v. Sturm, 
    673 F.3d 1274
    , 1281 (10th Cir. 2012) (barring review under the invited-error doctrine
    where the defendant proffered the very instruction he attacked on appeal). So Ellis
    did not invite error as the government contends.
    22
    In Alleyne v. United States, 
    133 S. Ct. 2151
    , 2155 (2013), the Supreme Court
    held that “any fact that increases the mandatory minimum [sentence] is an ‘element’
    that must be submitted to a jury.”11 Put another way, the Court held that a district
    court violates the Sixth Amendment if it imposes a sentence based on a judge-found
    (and not a jury-found) fact that increases a minimum sentence. See 
    id. at 2163–64.
    Thus, in Alleyne, the Supreme Court reversed a mandatory-minimum sentence
    increased from five to seven years under 18 U.S.C. § 924(c)(1)(A)(ii) for the
    defendant’s having brandished a firearm. 
    Id. It did
    so because the district court, and
    not the jury, had found this fact that increased the mandatory-minimum sentence. 
    Id. at 2163.12
    In Alleyne, the defendant’s “brandishing” of the firearm was plainly an
    element of the crime. See 
    id. at 2156;
    18 U.S.C. § 924(c)(1)(A)(ii). But Ellis’s
    increased mandatory-minimum sentence depended on conspiracy-cocaine amounts,
    not the manner of using a firearm. So to succeed on his Alleyne argument, Ellis must
    11
    Alleyne overruled Harris v. United States, 
    536 U.S. 545
    (2002), where the
    Court “held that judicial factfinding that increases the mandatory minimum sentence
    for a crime is permissible under the Sixth 
    Amendment.” 133 S. Ct. at 2155
    .
    12
    The government charged the brandishing element, and a special-verdict form
    gave the jury the opportunity to find that Alleyne had indeed brandished the firearm.
    The jury found that Alleyne had used the firearm but left blank the space indicating
    that Alleyne had brandished it. 
    Alleyne, 133 S. Ct. at 2156
    ; see Indictment, United
    States v. Alleyne, 3:10-cr-00134-REP-1 (E.D. Va. May 5, 2010), Verdict Form,
    United States v. Alleyne, 2:10-cr-00134-REP-1 (E.D. Va. Sept. 7, 2010). So it is not
    enough for the government to argue that a guilty verdict on a conspiracy count
    charging 5 kilograms of powder and cocaine and 280 grams of crack cocaine satisfies
    the government’s obligation to prove that element. As in Alleyne, merely charging
    the fact that increases the mandatory-minimum sentence is not enough—the jury
    must make that fact finding.
    23
    still show that individually attributable cocaine amounts are an element of the
    cocaine-conspiracy charge. On this point, the government asserts that “this Court has
    not issued a published decision [after Alleyne] expressly stating what determination
    the jury must make when a defendant is charged with an offense that carries a
    statutory mandatory-minimum penalty.” Appellee’s Br. at 29–30. But the government
    is mistaken.
    In United States v. Dewberry, 
    790 F.3d 1022
    (10th Cir. 2015), decided two
    years after Alleyne, we said that, because 280 grams of crack cocaine would increase
    the statutory mandatory-minimum sentence, that drug amount “was an element of the
    offense and had to be proved at trial.” 
    Id. at 1029
    (citing 
    Alleyne, 133 S. Ct. at 2158
    ).
    In Dewberry, the district court properly had the jury make a special finding beyond a
    reasonable doubt about the amount of crack cocaine individually attributable to the
    defendant. 
    Id. at 1029
    . The jury found that he had conspired to distribute at least 280
    grams of crack cocaine. 
    Id. In evaluating
    the defendant’s sufficiency-of-evidence
    challenge, we said that “[a] defendant can be held ‘accountable for that drug quantity
    which was within the scope of the agreement and reasonably foreseeable’ to him.” 
    Id. at 1030
    (quoting United States v. Arias-Santos, 
    39 F.3d 1070
    , 1078 (10th Cir.
    1994)).13 We concluded that the government had presented sufficient evidence to
    13
    Though Dewberry was decided after Ellis’s trial, he gets any benefit from its
    ruling because it was decided while his case is on direct appeal. Griffith v. Kentucky,
    
    479 U.S. 314
    , 328 (1987). And Ellis could even rely on United States v. Stiger, 
    413 F.3d 1185
    (10th Cir. 2005), which directed that in setting a drug sentence, the district
    judge “may determine the ‘floor’ by finding the precise drug quantity attributable to
    each coconspirator.” 
    Id. at 1193.
    Though Alleyne reassigned this role to the jury, the
    24
    prove that the defendant “could have foreseen that [his coconspirator] would convert
    powder cocaine into 280 grams or more of crack cocaine.” 
    Id. at 1030
    .
    In view of the interplay between Alleyne and Dewberry, we hold that the
    district court committed Alleyne error by convicting and sentencing Ellis on 21
    U.S.C. § 841(b)(1)(A) without the jury’s having found his individually attributable
    amount of cocaine as at least 5 kilograms of powder cocaine or 280 grams of crack
    cocaine.14 So we turn now to whether this Alleyne error requires a reversal. In doing
    so, we must first determine what standard of review applies. And that depends on
    whether Ellis preserved an objection in the district court to the Alleyne error.
    In determining whether Ellis preserved an Alleyne objection, we must
    determine when an Alleyne error arises. Here, the Alleyne error arose when the
    district court sentenced Ellis to a life sentence under 21 U.S.C. §§ 841(a)(1),
    (b)(1)(A) and 851. We see no reason to require that Ellis have objected during trial to
    the jury instructions or the general-verdict form to preserve an Alleyne objection. If
    measure stays the same—drug quantities for minimum sentences must be attributed
    individually.
    14
    The drug weights under 21 U.S.C. § 841(a)(1), (b)(1)(A), (B), and (C)
    establish different crimes, United States v. Jones, 
    235 F.3d 1231
    , 1236 (10th Cir.
    2000), but the statute does not say whether the drug weights are those of the
    conspiracy as a whole, or those of each defendant’s individually attributable
    amounts. We note that, at least for now, one circuit applies the conspiracy-wide
    amount for both maximums and mandatory-minimum sentences under this section.
    See United States v. Gibson, 
    2016 WL 6839156
    , at *2 (6th Cir. Nov. 21, 2016)
    (recognizing that conspiracy-wide liability for limited-amount coconspirators “may
    appear unjust” and does not “serve the drug statute’s underlying purpose of more
    severely punishing larger-amount drug dealers,” the court declared itself bound by its
    precedent) (citing United States v. Robinson, 
    547 F.3d 632
    , 638 (6th Cir. 2008),
    rehearing en banc granted, 
    854 F.3d 367
    (2017)).
    25
    the government wanted a heightened sentence under that subsection, it was obliged to
    ensure the jury received proper jury instructions and a special-verdict form with
    spaces enabling the jury to find Ellis’s individually attributable powder and crack-
    cocaine amounts. See United States v. Haines, 
    803 F.3d 713
    , 740 (5th Cir. 2015)
    (concluding that defendants’ challenge at their sentencing hearing to their mandatory
    minimum sentences based on conspiracy-wide heroin amounts, though not raised
    with an ideal level of specificity, were timely and sufficient to preserve their
    objections); United States v. Pizarro, 
    772 F.3d 284
    , 296 (1st Cir. 2014) (concluding
    that defendant preserved an Alleyne objection even though he did not object until
    sentencing, reasoning that a party is not obliged to object to something “inimical to
    his cause,” ensuring his eligibility for a longer sentence) (quoting United States v.
    Pérez–Ruiz, 
    353 F.3d 1
    , 14 (1st Cir. 2003)). The district court did not commit an
    Alleyne error until it subjected Ellis to an increased mandatory-minimum sentence
    without the jury’s attributing at least 280 grams of crack cocaine to Ellis
    individually.15
    15
    Had the district court sentenced Ellis to the mandatory-minimum term for
    conspiracy-wide cocaine amounts—10 years—that sentence would have fallen within
    the § 841(a)(1), (b)(1)(C) range of 0 to 30 years. In that circumstance, the Alleyne
    error might have been harmless. See United States v. Long, 
    748 F.3d 322
    , 330 (7th
    Cir. 2014). But here the Alleyne error led to a life-without-release sentence under §
    851 that never could have happened otherwise. The problem is not with the fact of
    the prior felony convictions, see Almendarez-Torres v. United States, 
    523 U.S. 224
    ,
    243 (1998) (prior convictions are not facts increasing a sentence that require jury
    findings), but with the sentencing increase made available by the Alleyne error.
    26
    Next, we must determine whether Ellis raised an Alleyne objection before the
    district court sentenced him. He could do so by invoking the applicable decision
    (here, Alleyne) “or by claiming that ‘the issue of drug quantity should go to the
    jury, . . . that an element of the offense was not proved, that the judge cannot
    determine quantity, or that quantity must be proved beyond a reasonable doubt (and
    not by a preponderance of the evidence).’” United States v. Lott, 
    310 F.3d 1231
    , 1240
    (10th Cir. 2002) (omission in original) (quoting United States v. Candelario, 
    240 F.3d 1300
    , 1304 (11th Cir. 2001)).
    Appearing pro se at the sentencing hearing, Ellis raised a sufficient Alleyne
    objection to the district court’s sentencing him on 280 grams or more of crack-cocaine
    without a jury finding that he was individually responsible for this amount:
    I don’t understand why I’m here today. And for the jury to find me guilty, I
    didn’t understand because there was no amount – I didn’t even – the jury
    transcripts, it was no amount to say if I was guilty of 280 grams. I mean,
    even the videos that I was in does not show me specifically with crack
    cocaine in possession selling to no one. You know.
    ***
    And I was never shown to be convicted by the jury by a certain drug
    amount because 280 grams, there’s never no evidence, to my knowledge,
    that’s being brought up.
    R. Vol. V (3165) at 1644, 1686.
    In addition, we conclude that Ellis sufficiently raised an Alleyne objection to the
    district court’s sentencing him on five kilograms or more of powder cocaine without a
    jury finding. In a motion hearing five months before his sentencing hearing, Ellis argued
    that he should not be held accountable for cocaine distributions by the Mexican cartel and
    27
    its distributors—“I didn’t know none of these dudes.” 
    Id. at 1591.
    He complained that his
    attorney didn’t present to the jury that “this is a conspiracy here and it’s another case
    here, so, I mean, you ought to separate Mr. Ellis from this conspiracy[.]” 
    Id. at 1593.
    And at his sentencing hearing, Ellis complained that for his “guilty verdict [to]
    show that Perez and I combined to sell drugs is false because I don’t know him and he
    stated on the stand that he doesn’t know me.” 
    Id. at 1641.
    In arguing that appointing him
    new counsel would not delay the sentencing, Ellis argued that “[i]t would probably take
    them a week, two week’s time to look at what I was involved in to separate me from the
    rest of the conspiracy.” 
    Id. at 1652.
    Objecting to being held accountable for other
    defendants’ drugs, Ellis said, “So the amount of drugs that’s been placed on me, I
    wouldn’t want to call it so much as ghost dope because I didn’t have it. But it was
    presented in the courtroom. But I don’t know whose it was, but I never was in possession
    of it or seen doing anything with a certain amount.” 
    Id. at 1664.
    Ellis continued to object
    to being held accountable for cocaine in an overbroad conspiracy charge in these words:
    “And it was kind of like a lot easier for, I guess, the prosecutor to get the whole
    community wrapped up in one, tie them all in one to get it over with fast. And I don’t feel
    like everyone was connected.” 
    Id. Because the
    district court committed a constitutional error by not obtaining the
    jury’s finding on an element of the crime, we turn for guidance to Neder v. United States,
    
    527 U.S. 1
    (1999). In that case, the district court mistakenly determined that materiality
    was not an element of certain federal fraud statutes. 
    Id. at 4.
    That meant that the jury
    never found that element beyond a reasonable doubt. For this error, the Court applied a
    28
    constitutional harmless-error standard, one requiring the government to prove
    harmlessness beyond a reasonable doubt (as opposed to a structural-error standard
    requiring reversal per se). 
    Id. at 12–13,
    15. The Court found this standard met because the
    defendant “did not contest the element of materiality at trial,” and did not “suggest that he
    would introduce any evidence bearing upon the issue of materiality if so allowed.” 
    Id. at 15.
    The Court required that the evidence be “uncontested and supported by
    overwhelming evidence, such that the jury verdict would have been the same absent the
    error.” 
    Id. at 17.
    And the Court set the test for affirmance as “whether it appears ‘beyond
    a reasonable doubt that the error complained of did not contribute to the verdict
    obtained.’” 
    Id. at 15
    (quoting Chapman v. California, 
    386 U.S. 18
    , 24 (1967)).
    i.     Powder-Cocaine Conviction
    We first turn to Ellis’s conviction for conspiracy to distribute more than 5
    kilograms of powder cocaine. Despite the government’s cartel-heavy presentation at trial,
    it has abandoned that approach on appeal. And when those cartel amounts—hundreds of
    kilograms16—are stripped away, the government cannot show that the Alleyne error was
    harmless beyond a reasonable doubt. Ellis contested his liability for at least five
    kilograms of powder cocaine, and the government didn’t introduce overwhelming
    16
    On direct examination, Officer Eric Jones of the Kansas City Police
    Department estimated that Hector Aguilera was responsible for hundreds of
    kilograms of cocaine. R. Vol. IV at 2278.
    29
    evidence to prove that this amount was individually attributable to him. Even the
    presentence report, applying a preponderance standard, fell short of this mark.17
    ii.    Crack-Cocaine Conviction
    We next ask whether the government can show harmless error beyond a
    reasonable doubt with the necessary overwhelming evidence that Ellis conspired to
    manufacture or possess with intent to distribute and to distribute 280 grams of crack
    cocaine.18 Here, unlike with its Mexican-cartel powder-cocaine evidence, the
    government can rely on evidence more particular to Ellis—the crack cocaine cooked
    and sold by Tatum, Ellis, and Theoplis. The government points to the controlled buys
    from Tatum and Ellis totaling 25.3 grams. But that still leaves the government
    needing to show overwhelming evidence of another 254.7 grams needed to sustain
    the district court’s sentence. And here, Ellis contested this element at sentencing, and
    the record shows that the government’s proof of this remaining crack-cocaine amount
    is far from “uncontested and supported by overwhelming evidence.” 
    Neder, 527 U.S. at 17
    .
    To show that 280 grams of crack cocaine are individually attributable to Ellis,
    the government relies primarily on the testimony of Ellis’s nephew, Theoplis.
    17
    The PSR attributed to Ellis a total of 4,167 grams of cocaine from his and
    Tatum’s months of cocaine purchases from Sykes. Because of this calculation, we do
    not review the evidence of these cocaine-powder buys in detail.
    18
    Because of the government’s cartel-heavy presentation to the jury, and its
    failure during closing argument or rebuttal closing even to mention 280 grams of
    crack cocaine, we have doubts whether the jury convicted him of a crack-cocaine
    conspiracy of the aggravated crime under 21 U.S.C. § 841(b)(1)(A).
    30
    Theoplis responded affirmatively to the government’s question whether the powder
    cocaine Ellis purchased was “always cooked into crack cocaine.”19 R. vol. V (3165)
    at 678. But Theoplis admitted that he had just once seen Ellis cook powder cocaine
    into crack. Theoplis also testified that he had once seen Tatum cook crack at Tatum’s
    girlfriend’s house, after complying with Tatum’s request that Theoplis bring baking
    soda. Theoplis also testified that neither he, Tatum, nor Ellis bought crack cocaine.
    Finally, Theoplis testified that he sold “pieces” of crack cocaine for $10 or $20, and
    that Tatum and Ellis sold “weight”—meaning sixteenth- or eighth-ounce amounts. 
    Id. at 683–84.
    On appeal based on Theoplis’s testimony, the government argues that Ellis and
    Tatum cooked all their purchased powder cocaine into crack. If so, the government
    would have a strong basis to argue that Ellis and Tatum conspired to manufacture and
    distribute at least 280 grams of crack cocaine.
    But we are reviewing for constitutional harmless error, not for sufficiency of
    the evidence. And Theoplis’s testimony does not provide the “uncontested and
    overwhelming evidence” necessary for us to find the Alleyne error harmless beyond a
    reasonable doubt. In arguing otherwise, the government points us to two cases. But as
    discussed below, in both cases the government presented much stronger evidence of
    an omitted offense element than the government did here.
    19
    As mentioned, at arrest Ellis had a variety of drugs and paraphernalia, which
    included a small amount of powder cocaine but no crack.
    31
    First, in 
    Pizarro, 772 F.3d at 298
    , the government presented overwhelming
    evidence that far exceeded the drug amount necessary to trigger the mandatory-
    minimum sentence. Law-enforcement officials had seized 81 kilograms of cocaine
    from luggage at the airport. 
    Id. at 299.
    Further, multiple other witnesses testified that
    Pizarro had personally handled more than 5 kilograms of powder cocaine. 
    Id. Because overwhelming
    evidence supported Pizarro’s responsibility for more than 5
    kilograms of powder cocaine, the Alleyne error was harmless beyond a reasonable
    doubt. 
    Id. Second, in
    United States v. Mann, 
    786 F.3d 1244
    (10th Cir. 2015), we affirmed
    a defendant’s increased mandatory-minimum sentence under 18 U.S.C.
    924(c)(1)(A)(iii) because the evidence was “overwhelming” that Mann had
    discharged a firearm—an element omitted from the jury instructions. 
    Id. at 1251–52.
    In a recorded interview with FBI agents played to the jury, Mann admitted several
    times that he had discharged his firearm. 
    Id. at 1251.
    And on appeal, Mann conceded
    that the jury would have “found the mere fact of discharge of a firearm” had the
    verdict form asked the jury to answer that question.20 
    Id. at 1251–52.
    See also United
    20
    In a Fed. R. App. P. 28(j) letter, the government also cites United States v.
    Morris, 
    784 F.3d 870
    , 875 (1st Cir. 2015), as “persuasive support” for its
    overwhelming-evidence argument. In Morris, the defendant’s counsel conceded
    during closing argument that the jury should attribute 4 transactions to him, each with
    62 grams of powder cocaine, and that the jury could attribute crack cocaine from
    those 248 grams of crack on a 1:1 
    ratio. 784 F.3d at 875
    . The First Circuit had no
    trouble finding overwhelming evidence of at least another 32 grams of crack cocaine,
    noting that Morris himself testified that he was involved “in about eight other drug
    transactions of at least 28 grams each.” 
    Id. at 876.
    On the other hand, Ellis’s counsel
    disputed the cocaine amounts during trial, and Ellis himself did so at sentencing.

    ) (stating the government must show “a corpus of evidence such that no
    reasonable jury could find, based on the record, that the [drug] quantity was less than
    that required for the mandatory minimum to apply”).
    Here, Ellis contested conspiring to manufacture and distribute at least 280
    grams of crack cocaine. Our review of the record does not persuade us that the
    government offered overwhelming evidence to satisfy this omitted element “such that
    the jury verdict would have been the same absent the error.” 
    Neder, 527 U.S. at 17
    .
    Put another way, the government has not presented “a corpus of evidence such that
    no reasonable jury could find, based on the record, that the [drug] quantity was less
    than that required for the mandatory minimum to apply.”

    C.     The Government’s United States v. Stiger Argument
    1.     How Stiger Fits into the Analysis
    Taking a wide turn around these Alleyne problems, the government asserts that
    this circuit “has adopted the conspiracy-wide approach for statutory maximums.”
    Appellee Br. at 29; 57. The government treats the general verdict as a jury finding
    that the conspiracy as a whole involved at least five kilograms of powder cocaine and
    Certainly, Ellis never admitted that he was involved with either 5 kilograms of
    powder cocaine or 280 grams of crack cocaine.
    33
    280 grams crack cocaine.21 From this, the government implicitly argues that the
    conspiracy conviction sets a 10-to-life sentencing range under § 841(b)(1)(A), which
    authorizes Ellis’s life sentence. Because the government relies on United States v.
    Stiger, 
    413 F.3d 1185
    (10th Cir. 2005) to render the Alleyne-Dewberry problem
    moot, we examine Stiger in detail.
    In Stiger, the court reviewed a conviction in a much smaller conspiracy than
    charged in Ellis’s 
    case. 413 F.3d at 1189
    . Stiger was intimately involved in the
    conspiracy’s workings. For example, he helped prepare drugs for shipping and
    assisted in transporting the drugs as well as transferring large sums of money. 
    Id. As Ellis
    did here, Stiger received a mandatory life sentence because of the conspiracy’s
    drug weight and two prior felony convictions. 
    Id. at 1191.
    On appeal, Stiger argued that the district court had violated his Sixth
    Amendment rights “by not requiring the jury to make a specific finding as to the
    amount of drugs for which he was personally responsible.” 
    Id. In that
    case, unlike
    here, the jury had at least found that the conspiracy as a whole had trafficked more
    than 5 kilograms of powder cocaine. 
    Id. The court
    declared that Stiger had raised an
    issue of first impression in our court—“whether a jury, after Apprendi and Booker,
    21
    But the government cannot excuse a lack of a jury finding of an element
    (here drug weight) by relying on a guilty verdict for an indictment count charging
    that element. For instance, in a prosecution under 18 U.S.C. § 924(c)(1)(a)(ii), as in
    Alleyne, the government is not excused from obtaining a jury finding on
    “brandishing” by charging that element in the indictment. See, e.g., United States v.
    Kiel, 658 F. App’x 701, 705, 710 (5th Cir. 2016); United States v. McKinley, 
    732 F.3d 1291
    , 1293, 1297 (11th Cir. 2013); United States v. Mack, 
    729 F.3d 594
    , 607-08
    (6th Cir. 2013). Here, the jury did not make a finding of the cocaine quantities
    charged, let alone that those quantities were reasonably foreseeable to Ellis.
    34
    must determine the amount and type of drug attributable to individual coconspirators
    rather than simply attributable to the entire conspiracy.” 
    Id. at 1192.
    We joined five
    other circuits22 in announcing a rule that “in the conspiracy context, a finding of drug
    amounts for the conspiracy as a whole sets the maximum sentence that each
    coconspirator could be given.” 
    Id. (citing Derman
    v. United States, 
    298 F.3d 34
    , 42
    (1st Cir. 2002)). We then left it to the district judge to “determine the ‘floor’ by
    finding the precise drug quantity attributable to each coconspirator.” 
    Id. at 1193.
    We don’t read Stiger as giving an unqualified rule that, in wide global
    conspiracies as charged here, the lowest street-level dealers are automatically subject
    to the same maximum penalties as drug kingpins. Indeed, in United States v. Evans,
    
    970 F.2d 663
    , 670 (10th Cir. 1992), decided 13 years before Stiger, we noted that
    defendants must “have a general awareness of both the scope and the objective of the
    22
    Notably, of these five circuits, those that have revisited the issue post-
    Alleyne have not reached Stiger’s result. See 
    Cruse, 805 F.3d at 817
    (concluding that
    the district court erred in telling the jury that the two defendants were responsible for
    the cocaine involved in the conspiracy and all acts of the coconspirators in
    furtherance of the conspiracy and not telling the jury that the acts must be reasonably
    foreseeable to the two defendants); 
    Haines, 803 F.3d at 740
    –42 (though stating that
    “for determining statutory minimum and maximum sentences, our cases always have
    limited the defendant’s liability to the quantity of drugs with which he was directly
    involved or that was reasonably foreseeable to him,” the court went on to say that
    whether conspiracy-wide amounts apply to determine statutory maximums is “a
    bridge we need not cross today”); 
    Pizarro, 772 F.3d at 293
    (explaining that
    “[h]enceforth, under Alleyne and Apprendi, the jury must find the mandatory-
    minimum and statutory-maximum triggering elements,” in drug cases based on drug
    quantity). And another of the cited circuits reached a different result even earlier.
    
    Collins, 415 F.3d at 314
    (reversing drug sentence because “the district court’s
    sentence effectively attributed to Collins, an individual member of the conspiracy,
    the quantity of cocaine base distributed by the entire conspiracy”).
    35
    enterprise to be regarded as a coconspirator.” And we followed those words with a
    general limitation on a conspiracy’s reach:
    This is not to say, however, that a defendant may be convicted of a
    conspiracy that defies common sense simply because he or she
    possesses a general awareness of the breadth of its illegal activities. For
    example, at oral argument, the government suggested that a drug dealer
    who knows that his supply can be traced to the Medillin cartel has
    joined a vast conspiracy with the members of the cartel to distribute
    crack illegally for profit. Under such an approach, a small-time drug
    dealer could be held responsible for all of the drugs originated by the
    cartel for sentencing purposes, resulting in a guaranteed life sentence.
    Such an approach would pervert the concept of conspiracy. Mere
    knowledge of illegal activity, even in conjunction with participation in a
    small part of the conspiracy, does not by itself establish that a person
    has joined in the grand conspiracy.
    
    Id. Under the
    government’s reading of Stiger, any prosecution built upon a
    sufficiently wide conspiracy involving a defendant with two prior felony-drug-
    offense convictions would require a mandatory life-without-release sentence—
    regardless of how little of the conspiracy-wide drugs are individually attributable to
    that defendant. For a variety of reasons, we reject that interpretation of Stiger.
    First, Stiger itself found it important that the district court had “determined
    Mr. Stiger was integral to the conspiracy and could be sentenced as though he were
    responsible for the full drug types and 
    quantities.” 413 F.3d at 1192
    (emphasis
    added). And in rejecting Stiger’s appeal, we noted that substantial evidence showed
    that he had taken “essential and integral steps to help the organization profit from the
    sale of illegal drugs.” 
    Id. at 1194
    (emphasis added). We carefully reviewed the
    evidence against Stiger—extensive testimony about his packaging and coordinating
    36
    drug shipments, about his sending large amounts of money to the head man in the
    conspiracy, and about his gruesome torture of a woman concerning a dispute about
    drug-sale proceeds. 
    Id. at 1191.
    In comparison, we cannot say that Ellis was integral
    to the vast conspiracy charged in this case. After all, Ellis was a relatively small-time
    drug dealer, and the Mexican cartel was importing hundreds of kilograms of cocaine
    into the Kansas City area.23 We read Stiger to say that conspirators who are “integral”
    to an entire conspiracy can be sentenced at the conspiracy-wide drug amount.
    In our view, conspirators are “integral” when their individually attributable
    drug amounts correspond to the conspiracy-wide drug amounts. This approach reads
    Stiger in closer harmony to our circuit’s precedents than does the government’s
    approach. Obviously, Stiger did not overrule Evans and its prohibition against cartel-
    wide liability for small participants. Evans denounced the sort of conspiracy liability
    that the government argued to the 
    jury.24 970 F.2d at 670
    . As mentioned, it required
    that conspiracy convictions obey common sense, requiring more than “a general
    awareness of the breadth of its illegal activities.”25 
    Id. It described
    cartel liability for
    23
    Left unexplained in Stiger is how a district court’s finding that Stiger was
    “integral” to the conspiracy is not, under Apprendi, a fact that increases the
    maximum sentence, and so requires a jury finding.
    24
    At Ellis’s sentencing, the prosecutor explained the government’s approach to
    the case as follows: “As the evidence unfolded, Mr. Ellis wants to say, well, I didn’t
    know Perez-Alcala, and I agree he didn’t, but the drugs that Perez-Alcala and Hector
    Aguilera [the “kingpin”] were getting were ending up in the hands of Marvin Ellis.
    That’s why he’s connected.” R. Vol. V (3165) at 1668.
    25
    On this general-awareness point, the government’s examination of
    cooperating-witness Theoplis is revealing:
    37
    small-time drug dealers an approach that “would pervert the concept of conspiracy.”
    
    Id. And we
    decided Stiger after we decided other cases imposing a personal-
    responsibility limitation on conspiracy liability. See, e.g., 
    Arias-Santos, 39 F.3d at 1078
    (concluding that the defendant “may be sentenced on the basis of cocaine
    possessed by another conspirator, so long as the amount is within the scope of the
    conspiracy and foreseeable by [her]”); United States v. Russell, 
    963 F.2d 1320
    , 1322
    (10th Cir. 1992) (quoting Pinkerton v. United States, 
    328 U.S. 640
    , 646–47 (1946)

    furtherance of the conspiracy and crimes committed “within the scope of the
    unlawful project”26 and thus “reasonably foreseen as a necessary or natural

    Q:    Well, it was coming from somewhere, would you agree with that?
    A:    Correct.

    26
    In its closing argument, the government told the jury that “it’s not important
    that any particular defendant knew much at all about the overall scope of the
    conspiracy.” R. vol. V. (3165) at 1475.
    38
    consequence of the unlawful agreement”).27 And our post-Stiger cases cite and rely
    on these earlier cases too. See 
    Dewberry, 790 F.3d at 1030
    (determining that
    evidence was sufficient to support a crack-cocaine sentence, citing Arias-Santos
    favorably to conclude that a reasonable jury could find that Dewberry “could have
    foreseen that Mr. Webb would convert powder cocaine into 280 grams or more of
    crack cocaine”).
    2.     How Alleyene Affects Stiger28
    Alleyne directly overruled Stiger on one point. Stiger directed that the district
    court, and not the jury, find the sentencing “floor” based on individually attributable
    drug amounts. 
    Stiger, 413 F.3d at 1193
    . But the Alleyne-Dewberry tandem requires
    that the jury make this fact finding if it increases a mandatory-minimum sentence. So
    what did Stiger mean by the sentencing “floor”? 
    Id. Did this
    reference allow a district
    court to ignore the mandatory-minimum sentence associated with the statutory
    sentencing range given by the conspiracy-wide drug amount? In other words, if the
    jury found that the conspiracy-wide amount was at least 280 grams of crack cocaine,
    would Stiger open the door to § 841(a)(1), (b)(1)(A) for the maximum life sentence,
    27
    In United States v. Allen, 9 F. App’x 936, 938 (10th Cir. 2001)
    (unpublished), we said that “because the jury did not determine the amount of drugs
    attributable to defendant,” we could not uphold under Apprendi “a conviction for the
    quantities identified in § 841(b)(1)(A) or (B)[.]”
    28
    Judge Hartz joins the opinion in full except for Discussion Section I.C.2,
    which he does not join.
    39
    but somehow ignore the corresponding 10-year mandatory-minimum sentence?29
    Obviously, courts have no authority to disregard a statutory sentencing range. So I
    interpret Stiger’s sentencing “floor” to be the mandatory-minimum sentence plus
    whatever increase a defendant’s relevant conduct under the sentencing guidelines
    gives. I cannot construct a 0-to-life sentencing range by merging § 841(b)(1)(A), (B),
    or (C).
    Until Alleyne-Dewberry, Stiger’s one-size-fits-all approach, whatever its
    wisdom, was at least legally permissible (if the “floor” could not go beneath the
    mandatory minimum). But Alleyne-Dewberry changes that. Now, the mandatory-
    minimum sentence is unhitched from the conspiracy-wide maximum sentence. In a
    reversal of fortune, Stiger’s conspiracy-wide maximum sentence is now limited by
    the mandatory-minimum sentence’s statutory range. For example, if a defendant’s
    individually attributable amount of crack cocaine is 100 grams, that compels a
    statutory sentencing range of 5 to 40 years, under § 841(b)(1)(B). And even if the
    conspiracy-wide crack-cocaine amount far exceeds 280 grams, the maximum cannot
    rise past 40 years without creating a new sentencing range of 5 years to life. Nothing
    29
    In 
    Morales, 108 F.3d at 1225
    , we stated that “[in] general, ‘district courts
    have broad discretion in sentencing a defendant within the range prescribed by
    Congress.’” (quoting United States v. Robertson, 
    45 F.3d 1423
    , 1448 (10th Cir.
    1995)).
    40
    in § 841(b) suggests that Congress intended us to merge its precise statutory
    sentencing ranges in this fashion.30
    And there lies a problem for the government. To sustain Ellis’s life-without-
    release sentence, it must show that Ellis’s offense is one “involving” at least 280
    grams of crack cocaine, 21 U.S.C. § 841(a)(1), (b)(1)(A)(iii), before it can reach a
    sentencing range of 10-years-to-life imprisonment. But after Alleyne-Dewberry, we
    must ask whether the offense involves that much individually attributable cocaine
    before imposing the associated sentencing range that includes the 10-year mandatory-
    minimum sentence. A conspiracy-wide crack-cocaine finding of 280 grams or more
    cannot establish the mandatory-minimum term of 10 years—only jury-found,
    individually attributable amounts can authorize that sentence for a defendant. And
    absent getting to § 841(a)(1), (b)(1)(A), the government cannot rely on § 851
    convictions to increase Ellis’s sentence to mandatory life without release.
    30
    The 5-year term is called a mandatory-minimum sentence for a reason. And
    the sentencing guidelines apparently agree, because in cases where a statutory
    minimum exceeds an advisory guideline range, the mandatory-minimum term
    becomes the guideline sentence. See U.S. Sentencing Guidelines Manual § 5G1.1(b).
    Even so, we recognize that the government has sometimes taken a contrary view
    without explanation. See 
    Dewberry, 790 F.3d at 1033
    (noting that the government
    agreed that a 10-year mandatory minimum sentence from the jury’s special-verdict
    finding that he conspired to distribute 5 kilograms or more of powder cocaine should
    be reduced to a five-year mandatory minimum sentence under § 841(b)(1)(B) because
    the PSR found him responsible for less than 5 kilograms); United States v. Biglow
    (Biglow II), 635 F. App’x 398, 399 (10th Cir. 2015) (unpublished) (explaining that
    the government conceded the district court’s error in imposing a five-year
    mandatory-minimum sentence based on a jury verdict finding that the conspiracy as a
    whole had involved at least 500 grams of powder cocaine, when the district court at
    sentencing attributed 192 grams to the defendant individually).
    41
    3.     Summary
    As stated, we read Stiger differently than the government does, and we vacate
    Ellis’s sentence under §§ 841(a)(1), (b)(1)(A) and 851 and remand that count for
    resentencing under §§ 841(b)(1)(C) and 851.31 In remanding cases for violations of
    Apprendi, we have ordered that the district court resentence under § 841(a)(1),
    (b)(1)(C) when the conviction stands but the sentence does not. See 
    Jones, 235 F.3d at 1236
    –37 (“A district court may not impose a sentence in excess of the maximum
    set forth in 21 U.S.C. § 841(b)(1)(C) unless the benchmark quantity of cocaine base
    for an enhanced penalty is alleged in the indictment in addition to being submitted to
    the jury and proven beyond a reasonable doubt.”); see also 
    Vazquez, 271 F.3d at 98
    (explaining that, because “drug quantity was neither submitted to the jury nor
    reflected in its verdict,” “§ 841(b)(1)(C) define[d] Vazquez’s prescribed statutory
    maximum sentence”).
    II.   Drug-Premises Conviction
    Ellis next argues that the evidence was insufficient to support his conviction
    for maintaining drug-involved premises. Although the indictment charges that this
    crime occurred “[o]n or about April 27, 2012,” Ellis ignores the “on or about”
    qualifier, concentrating instead on the particular date of April 27, 2012. R. vol. I
    (3165) at 585. According to Ellis, the government did not prove beyond a reasonable
    31
    In view of this holding, we have no need to address Ellis’s Fifth Amendment
    argument, one based on his asserted due-process right to avoid an “aggravated
    conspiracy charge” (longer imprisonment for more drug involvement) “based upon
    the conduct of others that is not reasonably foreseeable to him.” Appellant’s Opening
    Br. at 4.
    42
    doubt that he maintained 921 Haskell as a drug-trafficking house on April 27, 2012.
    The government contends that it proved that Ellis maintained the residence at 921
    Haskell for drug-trafficking purposes sometime within a few weeks of April 27,
    2012—a time period sufficiently close to April 27 to compel an affirmance.
    On appeal, Ellis argues that insufficient evidence supports this count of
    conviction. Further, he acknowledges that he did not object in the district court on
    sufficiency-of-evidence grounds. 
    Id. In this
    circumstance, we review Ellis’s
    challenge under the plain-error standard. United States v. Goode, 
    483 F.3d 676
    , 681
    (10th Cir. 2007). To meet his burden under this standard, Ellis must show that the
    district court committed “(1) an error, (2) that is plain, which means clear or obvious
    under current law, and (3) that affects substantial rights.” If Ellis does so, “this Court
    may exercise discretion to correct the error if it seriously affects the fairness,
    integrity, or public reputation of judicial proceedings.” 
    Id. (quoting United
    States v.
    Kimler, 
    335 F.3d 1132
    , 1141 (10th Cir. 2003)).
    We conclude that Ellis has not even shown error. First, as noted, the
    indictment was not limited to a specific date—instead, it charged Ellis with violating
    § 856 “on or about April 27, 2012.” R. vol. I (3165) at 585. Indeed, the government
    produced evidence of Ellis’s maintaining 921 Haskell as a drug premises during the
    month before the date charged in the indictment. When an indictment lists a specific
    date, the government must produce “some evidence which tends to show that the
    defendant committed the charged offense on ‘a date reasonably near to the specified
    date’ alleged in the indictment.” United States v. Charley, 
    189 F.3d 1251
    , 1273 (10th
    43
    Cir. 1999) (reversing because the evidence showed the defendant’s actions from two
    years before the date listed on the indictment) (quoting United States v. Castillo, 
    140 F.3d 874
    , 885 (10th Cir. 1998)). Evidence that a defendant committed the crime
    within a few weeks of the specified date suffices. 
    Id. at 1272;
    see also Kokotan v.
    United States, 
    408 F.2d 1134
    , 1138 (10th Cir. 1969) (“[I]f the prosecution proves that
    the offense was committed within a few weeks of the date, the proof will be deemed
    sufficient to hold defendant responsible for the charge.”).
    The government proved that Ellis maintained 921 Haskell as a drug premises
    within a few weeks of April 27. The jury heard a phone call between Ellis and an
    unidentified male on April 4, 2012 on a phone line that Ellis, Tatum, and others used
    for drug sales—some of which took place at 921 Haskell. Whenever, if ever, the spat
    between Tatum and Ellis ended, Ellis’s use of this phone suggests that it had not
    begun by April 4, 2012. Ellis points to a recorded phone call between Tatum and an
    unknown male on April 12, 2012, where Tatum says that he and Ellis had a “falling
    out.” R. vol. III (3165) at 2287–88. But the government produced a utility bill for 921
    Haskell for service from April 13 to May 14, 2012, still in Ellis’s name. Contrary to
    Ellis’s contention that he did not have a “requisite connection” to 921 Haskell,
    Appellant’s Opening Br. at 31, the utility bill—one reasonably near the date listed on
    the indictment—was evidence upon which the jury could rely in convicting Ellis of
    this count. Cf. United States v. Renteria-Saldana, 
    755 F.3d 856
    , 859–60 (8th Cir.
    2014) (concluding that the two-level drug-house sentencing enhancement was proper
    based on, in part, the defendant’s having and paying the utility bills for the house).
    44
    III.   Conviction for Firearm Possession in Furtherance of Drug Trafficking
    Next, Ellis argues that the evidence was insufficient to sustain his conviction
    under 18 U.S.C. § 924(c) for possessing a firearm in furtherance of a drug-trafficking
    crime. Ellis contends that the drugs and other items he was carrying—namely, the 2.5
    grams of powder cocaine—were for personal use, not distribution.
    Ellis acknowledges that he did not move for acquittal, so we again review for
    plain error. 
    Goode, 483 F.3d at 681
    .
    To establish a § 924(c) violation, the government must prove that Ellis (1)
    committed a drug-trafficking offense (2) and knowingly possessed a firearm (3) “in
    furtherance of” that crime. United States v. Nava-Sotelo, 
    354 F.3d 1202
    , 1205 (10th
    Cir. 2003). To support this conviction, the government must establish “some nexus”
    between the firearm and the drug-trafficking crime. United States v. Luke-Sanchez,
    
    483 F.3d 703
    , 706 (10th Cir. 2007). The government can use circumstantial evidence
    to show both an intent to possess the weapon, United States v. McGehee, 
    672 F.3d 860
    , 871 (10th Cir. 2012), and an intent to distribute drugs, United States v. Burkley,
    
    513 F.3d 1183
    , 1189 (10th Cir. 2008).
    We disagree with Ellis that he can show an error that was plain, let alone one
    that affected his substantial rights. Ellis claims that he had the 2.5 grams of powder
    cocaine for personal use, not distribution. But based on the evidence, the jury could
    rationally conclude that, when police arrested him on May 11, 2012, Ellis possessed
    45
    the cocaine with the intent to distribute it. After all, the jury knew from the evidence
    that Ellis was a drug dealer. And in evaluating what Ellis intended to do with the
    cocaine, the jury could consider that officers recovered from Ellis’s bag more
    evidence of drug dealing than the powder cocaine itself: an empty sandwich-bag box,
    a digital scale, about 32 grams of synthetic marijuana, 25.8 grams of PCP in a bottle,
    3.1 grams of marijuana, 16 mollies (ecstasy/MDMA), and 8 Diazepam pills. See
    United States v. Khondaker, 263 F. App’x 693, 701 (10th Cir. 2008) (unpublished)
    (holding that jury could conclude that the defendant possessed drugs for retail
    distribution based on the amount of drugs and the variety of drugs found—including
    crack and powder cocaine, methamphetamine, and ecstasy); see also United States v.
    Triana, 
    477 F.3d 1189
    , 1195 (10th Cir. 2007) (describing scales and plastic baggies
    as “tools of the drug trade”). We affirm Ellis’s § 924(c) conviction.
    IV.   Right to Counsel at Sentencing
    Ellis next argues that the district court violated his Sixth Amendment right to
    counsel when it refused to appoint substitute counsel at sentencing and when it found
    that Ellis had knowingly waived his right to counsel. He asks us to vacate the
    sentences on all convictions and remand for resentencing after appointment of
    substitute counsel. Because we remand for a full resentencing, and now order that
    Ellis receive different counsel to assist him at the resentencing, we conclude that
    these claims are moot and address them no further.
    46
    V.     Supervised-Release Violation
    Ellis also filed an appeal in Appeal No. 14-3181 after the district court
    sentenced him to 24 months for the supervised-release violation. But in his appellate
    brief, Ellis makes one fleeting mention of this violation in his argument. He asserts
    that “Ellis is also entitled to substitute counsel in the related case involving the
    revocation of his supervised release. As noted above, the complete breakdown in
    communication between Mr. Ellis and Mr. DeHardt continued in the proceedings in
    that case.” Appellant’s Opening Br. at 40 n.7.
    Ellis’s bare assertion is insufficient to preserve this claim for our
    consideration. See United States v. Fishman, 
    645 F.3d 1175
    , 1194 (10th Cir. 2011)
    (concluding that “[w]e will not manufacture arguments for an appellant, and a bare
    assertion does not preserve a claim” that the appellant “fail[ed] to develop [the]
    argument or provide any citations to authorities or the record”); United States v.
    Hardman, 
    297 F.3d 1116
    , 1131 (10th Cir. 2002) (en banc) (“Arguments raised in a
    perfunctory manner, such as in a footnote, are waived.”). Ellis’s single footnote is
    insufficient to trigger our review.32 We decline to address this argument and affirm
    Ellis’s supervised-release-violation conviction and sentence.
    32
    Even if Ellis had preserved this argument, we would conclude that Ellis
    knowingly and voluntarily waived counsel at the revocation-violation sentencing.
    Before proceeding, the district court asked Ellis whether he wanted to represent
    himself (to which Ellis responded affirmatively), whether Ellis understood the charge
    and the maximum sentence, and whether Ellis understood that it was a bad idea to
    represent himself, especially given his lack of any legal education. Based on these
    questions, we would conclude that the district court adequately covered topics such
    as the nature of the charges, the range of punishment, possible defenses, and a
    47
    CONCLUSION
    In Appeal No. 14-3165, we affirm all of Ellis’s convictions and all but one of
    his sentences—the mandatory-life sentence for the cocaine conspiracy. On that
    sentence, we conclude that the district court committed plain error under Alleyne by
    failing to obtain the jury’s findings on the conspiracy’s cocaine amounts reasonably
    foreseeable to Ellis. We further conclude that the district court’s errors were not
    harmless, because the government’s evidence was not overwhelming that Ellis could
    reasonably foresee at least 5 kilograms of powder cocaine in the conspiracy, and that
    Ellis (and his coconspirators Tatum and Theoplis) manufactured or sold at least 280
    grams of crack cocaine. Thus, we reverse Ellis’s conspiracy sentence and remand for
    a full resentencing, subject to the cocaine-conspiracy conviction being resentenced
    under 21 U.S.C. § 841(b)(1)(C). We affirm all of Ellis’s other convictions and
    sentences. In Appeal No. 14-3181, we affirm Ellis’s supervised-release-violation
    conviction and sentence.

    proceed pro se at sentencing. See
