    Before GRANT, TJOFLAT, and ED CARNES, Circuit Judges.
    TJOFLAT, Circuit Judge:
    Florida prisoner Gregory Lamar Blackmon appeals the
    District Court’s denial of his 
    28 U.S.C. § 2254
     habeas petition. We
    issued a certificate of appealability on the following two issues:
    (1) Whether the Florida District Court of Appeal
    (“DCA”) denial of Blackmon’s claim that his appellate
    attorney rendered ineffective assistance of counsel in
    not assigning as error in the appeal of Blackmon’s
    conviction of armed robbery the trial court’s failure
    sua sponte to inform Blackmon of the dangers of joint
    representation constituted a decision that was
    contrary to or an unreasonable application of
    Strickland v. Washington, 
    466 U.S. 668
    , 
    104 S. Ct. 2052
     (1984).
    (2) Whether the DCA denial of Blackmon’s claim that
    his trial attorney rendered ineffective assistance of
    counsel in failing to object to the prosecutor’s
    comments in closing argument to the jury about the
    truthfulness of Michael Chester’s testimony
    constituted a decision that was contrary to
    or an unreasonable application of Strickland v.
    Washington.1
    1 We have rephrased the issues for purposes of clarity. The original language
    was as follows: (1) “Whether Mr. Blackmon’s appellate counsel was ineffective
    for failing to argue that the trial court erred in its treatment of Mr. Blackmon’s
    decision to be jointly represented by his co-defendant’s counsel, and whether

    We conclude that the District Court properly denied
    Blackmon’s § 2254 habeas petition.
    I.
    A.
    On August 14, 2009, Michael Moore, the manager of
    Sonny’s BBQ restaurant on North Monroe Street in Tallahassee,
    Florida, had just finished closing the restaurant for the night and
    was walking towards his car when he was approached by three
    masked men in the parking lot. Moore attempted to get into his
    car and drive away, but the men forced him out of his car at
    gunpoint and tied his hands. The men then instructed him to
    unlock the restaurant, turn off the alarm, open the safe and give
    them its contents, which he did. The men then “hog-tied” Moore
    with wire and left. Moore quickly freed himself and called 9-1-1.
    The incident was captured on the restaurant’s surveillance video.
    On September 2, 2009, while in custody for an armed
    robbery of a Chevron gas station, Michael Chester told the
    the state court’s ruling on this claim was contrary to or an unreasonable
    application of clearly established federal law or was based on an unreasonable
    determination of the facts” and (2) “Whether Mr. Blackmon’s trial counsel was
    ineffective for failing to object to the prosecutor’s comments in closing about
    the truthfulness of Michael Chester’s testimony, and whether the state
    postconviction court’s ruling was contrary to or an unreasonable application
    of clearly established federal law or was based on an unreasonable
    determination of the facts.”

    18-11416                  Opinion of the Court                             4
    Tallahassee police that he was involved in the Sonny’s robbery2
    along with four other men: Jermaine Earl, Charles Green, Gregory
    Blackmon, and an unidentified man.3 Chester explained that he,
    Green, and Earl were the three masked gunmen who accosted
    Moore and committed the robbery and that Blackmon and the
    unidentified man had been driving back and forth on North
    Monroe Street in front of Sonny’s acting as lookouts. He said that
    Blackmon had communicated with Earl by cellphone during the
    robbery.
    During their subsequent investigation, the Tallahassee
    police recovered clothing in Earl’s residence that matched
    clothing worn by one of the robbers depicted on the Sonny’s
    surveillance video. The police also obtained the cell phone
    records for both Blackmon and Earl’s phones; the records
    indicated that they had been talking to each other during the time
    in which the robbery occurred. The records also indicated that
    2 Chester was arrested for the armed robbery of the Chevron station on
    August 20, 2009, and detained in the Leon County, Florida, jail. On September
    2, 2009, he confessed to the Tallahassee police that he was involved in that
    robbery, a robbery at Cash Advance, and the Sonny’s robbery.
    3 Chester could not remember the man’s name but seemed to remember that
    the man had worked at Sonny’s previously. The man told the group where
    the safe was located and the name of Sonny’s manager.

    18-11416                     Opinion of the Court                                   5
    both Blackmon and Earl were in the area around Sonny’s at the
    time of the robbery. 4
    On September 4, 2009, the Tallahassee police arrested
    Blackmon for the Sonny’s robbery5 and ten days later the State
    Attorney of Leon County filed an information charging him with
    the crime.6 The State Attorney filed a separate information against
    Earl. It charged him with kidnapping in addition to the Sonny’s
    robbery. 7 Both Blackmon and Earl pled not guilty and were
    provided court-appointed counsel. Because the same evidence
    would be presented against both defendants, the State moved the
    Court on February 5, 2010, to consolidate Blackmon’s trial with
    4 At trial, Detective Corbitt explained that an individual cell phone is always
    in contact with cellular telephone towers or cell site locations. Furthermore,
    a phone is constantly looking for the cellular tower or cellular site with the
    strongest signal; this is typically the cellular tower or cellular site closest to it.
    Cell phone carriers (such as AT&T or Verizon) record the cellular tower(s) or
    cellular site(s) that a phone is using for any given telephone call. Armed with
    this data, the police determined the general area in which Blackmon and Earl’s
    cell phones were being used at the time of the robbery.
    5 Blackmon was arrested on September 4, 2009. Earl was arrested shortly
    thereafter. A warrant was issued for Green’s arrest, but as of the time of
    Blackmon’s trial, the police had been unable to execute it. Officer Boccio
    testified that the warrant for Green was outstanding.
    6 The information was filed in the Circuit Court of Leon County. The State
    Attorney filed like informations against Earl and Chester.
    7 During a pretrial hearing, the prosecutor noted that while Blackmon had not
    been charged with kidnapping, such a charge could certainly follow.

    18-11416               Opinion of the Court                        6
    Earl’s. The Court granted the motion and ordered Blackmon and
    Earl to be tried jointly but with separate juries. Following
    consolidation, Earl and Blackmon both retained John Edward
    Eagen to represent them.
    On May 20, 2010, the Court set Earl and Blackmon’s trial
    date for the week of June 14, 2010. Prior to jury selection, Eagen
    informed the Court that Blackmon was concerned about how the
    joint trials would proceed, and that he was trying to explain the
    procedure to Blackmon. During the Court-counsel colloquy that
    ensued, Blackmon interrupted to say: “my concern was trying to
    get my point of innocence across to just my jury. I [don’t] want
    them to be distracted with other evidence because on my evidence,
    you know, they got me on whatever.” The Court, the prosecutor,
    and Eagen all explained to Blackmon that, because he was being
    tried as a principal to armed robbery, the State would present the
    same evidence regardless of whether the two trials were
    consolidated. Blackmon then stated that he understood that the
    same evidence would be presented, but that he did not want the
    same jury as Earl. Eagen again explained to Blackmon that he and
    Earl would have separate juries.
    At the end of this discussion, the prosecutor asked the Court
    “[i]f we could also reiterate [on the record] the waiver of [Blackmon
    and Earl] being represented by the same counsel for appellate
    purposes. I don’t want this to be an issue for appeal later. They
    chose to hire the same attorney. I want to make sure it’s clear
    they’re waiving that conflict.” Eagen responded, “We’ve done that

    so many times. We’ll do it one more time. You guys are fine with
    me representing both of you correct?” Blackmon responded,
    “Only if you argue in front of two different juries.” Earl nodded his
    head yes in response to the question.
    B.
    At trial, Chester testified in the State’s case. 8 He was its key
    witness in that he was the only one who could relate how the
    robbery was planned and, in particular, the roles Blackmon and
    Earl played. He presented the following story: at some point prior
    to the robbery, he had been staying at the Roadway Inn across the
    street from Sonny’s when Blackmon told him that he had a plan in
    the works to rob the restaurant. A few days before the robbery
    took place, Chester, Earl, and Green “cased” Sonny’s and observed
    how many people were working there and at what time they left
    work.
    Chester then told the jury how the robbery was carried out
    and how afterwards he, Green, the unidentified man, Blackmon
    and Earl met at Earl’s house to divide up the money. His
    description mirrored what he had told the police and the events set
    out in subpart A. Chester’s testimony focused, in part, on
    Blackmon and Earl’s involvement—especially the phone
    conversations they had while the robbery was in progress.
    8 Chester hoped that the prosecutor would recommend a lenient sentence.

    18-11416               Opinion of the Court                      8
    In cross-examining Chester, Eagen zeroed in on those
    conversations. He cast doubt on how Chester could have known
    that Blackmon was in fact acting as a look out, given North Monroe
    Street was not visible from the woods behind Sonny’s.
    Eagen: And when you and Mr. Green and Mr.—and
    you say Mr. Earl were in the woods, right?
    Chester: Yes, sir.
    Eagen: You were saying they were talking on the
    phones, right?
    Chester: Yes, sir.
    Eagen: And you’re saying—how do you know if you
    were in the woods, okay, and in the—can you see
    North Monroe from where you were?
    Chester: From in the woods?
    Eagen: Yeah, from the back of Sonny’s?
    Chester: No, sir.
    Eagen: Then how do you know that Mr. Blackmon
    was driving up and down the highway—the road on
    Monroe?
    Chester: Because that’s where he told us he was going
    to be at—
    Eagen: I didn’t ask you that. I asked— you don’t have
    any personal knowledge where Mr. Blackmon was
    that night? You’re assuming he was doing that? That’s
    what you believe, okay, correct?
    Chester: I guess so, sir.

    18-11416              Opinion of the Court                      9
    On redirect, the prosecutor further questioned Chester
    about Blackmon and Earl’s phone communications.
    Prosecutor: When is the last time you saw Gregory
    Blackmon when you were on your way to Sonny’s?
    Chester: When we left the house.
    Prosecutor: And when is the first time you saw him
    after the robbery?
    Chester: Back at the house.
    Prosecutor: Did Gregory Blackmon make any
    statements to you that he was doing what he said he
    would, that he was patrolling that street to look out?
    Chester: Yea, when we were in the woods when
    [Earl] called [Blackmon], [Earl] had told me too.
    Eagen: Objection, hearsay upon hearsay.
    Court: Overruled.
    Prosecutor: Go ahead, Mr. Chester. You can answer.
    Chester: When [Earl] was calling [Blackmon] in the
    woods, that’s what [Blackmon] told [Earl]. [Earl] said
    [Blackmon] was going—[Earl] said, I just saw
    [Blackmon’s] car go past because by the garbage cans
    you can see the street.
    In addition to Chester’s testimony, the State presented
    testimony from several officers who had been part of the
    investigation of the Sonny’s robbery. In particular, Investigator
    USCA11 Case: 18-11416       Date Filed: 05/19/2022    Page: 10 of 29
    18-11416               Opinion of the Court                       10
    Scott Cherry testified that a search of Earl’s residence had yielded
    clothing consistent with what was seen on the surveillance video
    of the robbery, as well as two cell phones. Officer Christopher
    Corbitt, an expert on cell phone tracking, testified that the cell
    phone records retrieved from Blackmon and Earl’s phones
    suggested that Blackmon and Earl had been talking to each other
    at the time of the robbery and that their phones had both been in
    close proximity to Sonny’s at that time as well.
    The defense’s closing jury arguments in the two cases were
    held separately. Thus, Eagen first addressed the jury in Blackmon’s
    case (and in the absence of Earl’s jury), and then the jury in Earl’s
    case (and in the absence of Blackmon’s jury). In summing up the
    case against Blackmon, Eagen argued that the State’s case was
    weak, one based on Chester’s testimony and little else. There was
    “no fingerprint evidence, no DNA, no footprints.” The cellphone
    records showed that Blackmon and Earl were talking to each other
    on the night of the robbery in the vicinity of Sonny’s, but Earl and
    Blackmon could have been “driving around as people do, talk[ing]
    on the cell phone as people do.” And Chester’s testimony, Eagen
    repeatedly emphasized, was suspect because Chester was “not a
    good Samaritan coming forth and saying, I am going to be
    truthful.” Chester, Eagen pointed out, was “out for [Chester].”
    “He’s got a motive to do the best he can to give [the State] the
    information” it wants in exchange for a more lenient sentence.
    The prosecutor, in contrast, reminded the jury of each piece
    of evidence that corroborated Chester’s testimony—including the
    USCA11 Case: 18-11416       Date Filed: 05/19/2022     Page: 11 of 29
    18-11416               Opinion of the Court                        11
    cell phone data and the clothing at Earl’s residence—and urged the
    jury to recognize that “[i]t all starts to add up when you look at the
    big picture and when you use [Chester’s] testimony as the glue to
    hold it all together.” The prosecutor addressed Chester’s
    credibility several times, always without a defense objection. We
    excerpt the relevant portions:
    Prosecutor: Michael Chester told you himself, that’s
    him. He has accepted responsibility for this case. He
    has told you, I went in there, and I robbed Sonny’s.
    He’s not trying to hide anything. He’s not trying to make
    himself sound better. But he has come in here and been
    honest with you about his involvement. And, yes, he does
    expect to get something from it. He           expects some
    consideration because he has been honest with law
    enforcement back in September. He has been honest with
    us, and he has been honest with you–all here today.
    ...
    He hasn’t been untruthful. If he came up here and
    lied, that’s perjury.
    C.
    The jury found Blackmon guilty as charged, and the Circuit
    Court sentenced him as a prison releasee reoffender (“PRR”) to life
    imprisonment. Blackmon appealed his conviction and sentence to
    the DCA. He presented two claims of trial court error: (1) the trial
    court erred in denying his peremptory challenge to a prospective
    juror under Batson v. Kentucky, 
    476 U.S. 79
    , 
    106 S. Ct. 1712
     (1986),

    18-11416                   Opinion of the Court                                12
    and (2) the trial court erred in sentencing him as a PRR because his
    PRR status was not alleged in the information.9 The DCA
    affirmed Blackmon’s conviction and sentence per curiam, without
    an explanatory opinion. State v. Blackmon, 
    75 So. 3d 270
     (Fla. 1st.
    Dist. Ct. App. 2011).
    On September 4, 2012, Blackmon, proceeding pro se, filed a
    petition for writ of habeas corpus in the DCA alleging ineffective
    assistance of appellate counsel under Strickland. 10 He argued that
    his appellate counsel was ineffective in failing to present several
    claims of trial court error on direct appeal. 11 Only one of the
    claims is relevant here: that his appellate counsel was ineffective in
    failing to argue that the trial court erred when it did not advise
    Blackmon sua sponte of the dangers of joint representation.
    Blackmon alleged that the court committed this error twice. The
    first error occurred, Blackmon claimed, during the colloquy
    between the Court, Blackmon, Eagen, and the prosecutor prior to
    jury selection after Blackmon said he was “concerned about
    9 These claims are not pertinent to the appeal before us.
    10 Under Florida law, claims of ineffective assistance of appellate counsel are
    brought before the DCA in the form of a habeas petition. Francois v. Klein,
    
    431 So. 2d 165
    , 166 (Fla. 1983). Claims of ineffective trial counsel are presented
    to the trial court by a Rule 3.850 motion under the Florida Rules of Criminal
    Procedure. 
    Id.
    11 Blackmon’s claims were that the trial court erred (1) in overruling a hearsay
    objection; (2) in denying his motion to strike two jurors for cause; and (3) in
    failing to advise him of the dangers of joint representation.
    USCA11 Case: 18-11416         Date Filed: 05/19/2022     Page: 13 of 29
    18-11416                 Opinion of the Court                       13
    counsel’s ability to provide him a fair trial due to [counsel] jointly
    representing both Petitioner and codefendant Earl.” This
    expression of concern, Blackmon asserted, should have prompted
    the Court to intervene sua sponte and inform him of the dangers
    of joint representation. The second error occurred, according to
    Blackmon, during Chester’s testimony when, over Eagen’s hearsay
    objection, Chester told the jury about the phone call that took
    place between Earl and Blackmon during the robbery. 12
    Blackmon’s petition described the trial court’s error in failing to
    intervene thus:
    [Blackmon] wanted to testify to the fact that Mr.
    Chester and Earl owed him a large sum of money for
    a drug debt and that he had threaten[ed] to do bodily
    harm to Mr. Chester if he did not come up with the
    money soon. . . . [It] was the trial court’s duty even if
    it was not aware of Petitioner’s desire to testify, to
    stop the trial and conduct a hearing, when it
    permitted the incriminating hearsay testimony of Mr.
    Chester to be introduced. As, it was clearly obvious
    that, in light of Mr. Chester’s testimony regarding
    what . . . Earl told him about petitioner, [Eagen] was
    placed in a peculiar situation as to how he would
    defend Petitioner from this hearsay accusation. And
    therefore, the court err[ed] . . . by failing to stop the
    trial and conduct[ ] a hearing to assure Petitioner’s
    12 See part I.B.

    constitutional rights to effective counsel were
    protected.
    The DCA denied the petition on the merits per curiam,
    without an explanatory opinion. State v. Blackmon, 
    98 So. 3d 201
    (Fla. 1st. Dist. Ct. App. 2012).
    On November 10, 2012, Blackmon moved the Circuit Court
    for postconviction relief pursuant to Florida Rule of Criminal
    Procedure 3.850. He submitted an amended petition on October
    2, 2013. His motion presented five claims. 13 Only one is relevant
    here: his trial counsel was ineffective under Strickland for failing to
    object to the prosecutor’s improper bolstering of Chester’s
    testimony in closing argument to the jury. failure to object,
    Blackmon argued, prejudiced his defense because Chester’s
    “credibility lay at the heart of the State’s case.”
    The Circuit Court conducted an evidentiary hearing on
    Blackmon’s motion. Eagen testified that his practice was to refrain
    from objecting to a prosecutor’s statement during closing
    argument because “all it does is draw more attention to the
    statement.” The Court found this to be a credible strategy, noting
    13 The claims were: that trial counsel was ineffective for (1) failing to object
    to the prosecutor’s improper bolstering of Chester’s testimony in summing up
    the State’s case before the jury, (2) failing to impeach Chester’s testimony, (3)
    failing to request an accomplice instruction to the jury, (4) failing to impeach
    Investigator Cherry’s testimony, and (5) failing to present alibi witnesses.

    that “[m]any attorneys take the view, as Eagen did, that, in the
    absence of something very egregious, it’s simply better not to
    object and not call attention to the state’s closing.” The Court
    therefore denied relief on Blackmon’s ineffective assistance
    claim.14 Blackmon appealed the decision to the DCA. The DCA
    affirmed it per curiam in without an explanatory opinion. State v.
    Blackmon, 
    150 So. 3d 1135
     (Fla. 1st. Dist. Ct. App. 2014).
    D.
    On March 20, 2015, having exhausted his state remedies,
    Blackmon, proceeding pro se, petitioned the U. S. District Court
    for the Northern District of Florida for a writ of habeas corpus
    pursuant to 
    28 U.S.C. § 2254
    . 15 In an amended petition, he
    presented ten claims. 16 Two are now before us: (1) appellate
    14 The trial court rejected Blackmon’s other ineffective assistance of counsel
    claims as well.
    15 Blackmon proceeded pro se throughout the litigation of his habeas petition
    in the District Court.
    16 Blackmon asserted the following claims: (1) the trial court erred in denying,
    under Batson, his attempt to exercise a peremptory challenge to excuse a
    potential juror; (2) appellate counsel was ineffective for failing to appeal the
    hearsay objection to Chester’s testimony regarding Blackmon and Earl’s
    phone calls; (3) appellate counsel was ineffective for failing to appeal the trial
    court’s failure to advise Blackmon of the dangers of joint representation; (4)
    trial counsel was ineffective for failing to impeach Chester; (5) trial counsel
    was ineffective for failing to object to the State’s closing argument; (6) trial
    counsel was ineffective for failing to request an accomplice argument; (7) trial
    counsel was ineffective for failing to impeach Officer Cherry; (8) trial counsel

    18-11416                   Opinion of the Court                                16
    counsel rendered ineffective assistance, on direct appeal, in not
    assigning as error the trial court’s failure to inform Blackmon sua
    sponte of the dangers of joint representation on two occasions 17
    and (2) trial counsel was ineffective in failing to object when the
    prosecutor bolstered Chester’s credibility during his closing
    argument to the jury.
    Recall that that the DCA denied the first claim in denying
    Blackmon’s habeas petition without an explanatory opinion. The
    was ineffective for failing to present alibi testimony; (9) collateral counsel was
    ineffective for failing to appeal all 3.850 claims; and, finally, (10) cumulative
    error.
    17 Blackmon’s amended habeas petition stated the ground as being:
    “Ineffective assistance[] of appellate counsel for failure to present claim that
    trial court committed revers[i]ble error by failing to advise petitioner of the
    adverse consequences of joint representation and allowing joint
    representation to continue after materialization of manifest conflict of
    interest.” In the “supporting facts” section of the amended petition, Blackmon
    mostly detailed the facts about the colloquy among the Court, Eagen, the
    prosecutor, and himself that occurred prior to jury selection, but not about
    Chester’s testimony. The court allowed Blackmon to add an attachment to
    the amended petition that stated, among other things: “Materialization of
    manifest conflict also occur[r]ed when the actual conflict of counsel not able
    to put Earl on stand to refute Chester[’]s testimony.” Because this Court has
    held that “[p]ro se pleadings are held to a less stringent standard than pleadings
    drafted by attorneys” and that such pleadings are to be “liberally construed,”
    we read Blackmon’s ineffective assistance of appellate counsel claim as
    including a claim based on Chester’s testimony. See Trawinski v. United
    Techs., 
    313 F.3d 1295
    , 1297 (11th Cir. 2002) (citing Tannenbaum v. United
    States, 
    148 F.3d 1262
    , 1263 (11th Cir. 1998) (per curiam)). Neither the
    Magistrate Judge nor the District Court considered the claim as it relates to
    Chester’s testimony. We therefore review that claim de novo in part III.A.ii.
    USCA11 Case: 18-11416       Date Filed: 05/19/2022     Page: 17 of 29
    18-11416               Opinion of the Court                        17
    DCA also denied the second claim, without an explanatory
    opinion, when it affirmed the Circuit Court’s denial of his Rule
    3.850 motion. The District Court’s task under § 2254 was to
    determine whether the DCA’s adjudication of each claim (1)
    resulted in a decision that was “contrary to, or involved an
    unreasonable application of,” the Supreme Court’s holdings in
    Strickland or (2) resulted in a decision that was based on an
    unreasonable determination of the facts in light of the evidence
    presented in the State court proceeding.” § 2254(d).
    Because the DCA adjudicated each of the claims per curiam
    without explanation, the District Court’s review of its decisions
    was necessarily guided by the Supreme Court’s instructions in
    Harrington v. Richter, 
    562 U.S. 86
    , 
    131 S. Ct. 770
    , 786 (2011), and
    Wilson v. Sellers, 
    138 S. Ct. 1188
     (2018). With respect to the habeas
    petition Blackmon presented to the DCA, because there was no
    underlying state court reasoning to review, the District Court was
    required to “determine what arguments or theories . . . could have
    support[ed] the [DCA’s] decision; and then . . . ask whether it is
    possible fairminded jurists could disagree that those arguments or
    theories are inconsistent with the holding in a prior decision” of the
    Supreme Court. Richter, 562 U.S.at 102, 
    131 S. Ct. at 786
    .
    With respect to the Rule 3.850 motion Blackmon presented
    to the DCA, because the Circuit Court stated on record its reasons
    for denying the motion, the District Court was required to employ
    the “look through” technique to consider the grounds the Circuit
    Court articulated in rejecting Blackmon’s ineffective assistance of
    USCA11 Case: 18-11416         Date Filed: 05/19/2022       Page: 18 of 29

     (holding that federal
    courts should “look through” the unexplained state decision to the
    last related state-court decision that does provide a relevant
    rationale).
    The District Court assigned the task of reviewing the
    respective DCA decisions under Richter and Sellers to a Magistrate
    Judge for the issuance of a report and recommendation (“R&R”)18
    as to the appropriate disposition of Blackmon’s claims. The
    Magistrate Judge issued an R&R on January 31, 2018, in which he
    recommended that the District Court deny Blackmon’s § 2254
    petition. We report the Magistrate Judge’s analysis of each claim
    in turn.
    As noted earlier, 19 Blackmon’s amended § 2254 habeas
    petition had two factual predicates presented in support of his
    claim of ineffective assistance of appellate counsel. The Magistrate
    Judge reviewed only the ineffective assistance claim,20 based on
    Blackmon’s argument that the trial court should have advised him
    of the dangers of joint representation following the pre-trial
    colloquy between Eagen, the prosecutor, Blackmon, and the
    18 See 
    28 U.S.C. § 636
    (b)(1)(B).
    19 See supra note 17.
    20 The same was true for the District Court given it adopted the Magistrate
    Judge’s R&R in full.

    Court.21 The Magistrate Judge found Blackmon’s claim to be
    “refuted by the trial record” detailing that colloquy and, moreover,
    by the record of the hearing the trial court held on Blackmon’s
    motion for a new trial. 22 As the Magistrate Judge explained:
    Prior to jury selection, Petitioner expressed concerns
    about the case having been consolidated pursuant to
    the State’s motion. The reason for consolidation was
    that identical evidence would be presented against
    both Petitioner and Jermaine Earl, although Earl was
    facing a kidnaping charge as a result of the crime, in
    addition to an armed robbery charge. Petitioner
    expressed that the jury might hear evidence relevant
    to the kidnaping charge that did not apply to him, but
    the court, the State, and defense counsel confirmed
    on the record that the evidence against both
    defendants was identical—the actions taken against
    the victim on the night of the robbery were also
    relevant to show that Petitioner was culpable as a
    principal to the crime of armed robbery. Counsel and
    the trial court affirmed that separate juries would
    21 The colloquy is set out in part I.A.
    22 In denying the claim on the basis of the record, the Magistrate Judge was
    following the Supreme Court’s instructions in Richter, albeit tacitly, to
    “determine what arguments or theories” the DCA could have drawn on in
    concluding that appellate counsel was not ineffective. Given his reasons for
    rejecting the claim under the criteria of § 2254(d), the Magistrate Judge
    effectively concluded, in keeping with Richter’s instructions, that it was
    possible that a fairminded jurist could conclude that such reasons were
    consistent with the Supreme Court’s holdings in Strickland.
    USCA11 Case: 18-11416      Date Filed: 05/19/2022     Page: 20 of 29
    18-11416              Opinion of the Court                       20
    consider the charges against each defendant.
    Petitioner had previously executed a waiver of his
    right to separate counsel. Prior to jury selection,
    Petitioner affirmed on the record that he agreed to
    joint representation by Eagen so long as two different
    juries were utilized.
    Following the trial, Petitioner filed a pro se motion
    for a new trial. At the hearing on the motion, the trial
    court reaffirmed that Petitioner and Earl had waived
    separate representation for purposes of their
    consolidated trial. The court observed that Petitioner
    and Earl had maintained their desire to be
    represented jointly by Eagen, provided that they each
    had a different jury. When Petitioner asserted that
    he personally did not think Eagen could represent
    both defendants, the court stated “[a]t every stage I
    asked you about that and you indicated that you were
    confident going with Mr. Eagen as the sole attorney.”
    Petitioner responded “I know, at every stage I kept
    saying that,” until he realized the case was
    “reconsolidated.” The record reflects that the
    concerns raised by Petitioner to the trial court were
    focused on potential adverse consequences from a
    consolidated trial rather than joint representation. As
    noted above, Petitioner agreed on the record that
    throughout the proceedings he had assented to joint
    representation by Eagen. Even if the trial court erred
    in some way in explaining any potential adverse
    consequences of joint representation, Petitioner
    points to nothing in the record that would support a
    USCA11 Case: 18-11416        Date Filed: 05/19/2022      Page: 21 of 29
    18-11416                Opinion of the Court                         21
    conclusion that he was prejudiced by appellate
    counsel’s failure to raise this as an issue on direct
    appeal. The record reflects that Petitioner’s primary
    complaint in the trial court was that the defendants
    would be tried by separate juries, and that is what he
    received. Again, appellate counsel’s failure to raise a
    claim will not be found prejudicial unless the claim
    would have a reasonable probability of success on
    appeal. Petitioner points to nothing in the record that
    would support a conclusion that his trial was
    prejudiced as a result of the joint representation by
    Eagen and the use of two jury panels, as Petitioner
    requested. . . . . Thus, Petitioner has failed to show
    that the state court’s rejection of this ineffective-
    assistance claim was contrary to, or an unreasonable
    application of, [Strickland’’s holdings], or resulted in
    an unreasonable determination of the facts in light of
    the evidence presented in state court. See 
    28 U.S.C. § 2254
    (d).
    Blackmon’s second claim was that trial counsel was
    ineffective “for failing to object to the State’s closing argument . . .
    that Chester had been honest with the jury regarding his
    involvement in the robbery . . . [and] that [his] testimony was
    unwavering, truthful, and that he had accepted responsibility for
    the crime.” According to Blackmon, this “argument amounted to
    impermissible vouching.”

    18-11416                   Opinion of the Court                             22
    The Magistrate Judge recommended that the District Court
    deny the claim. The Magistrate Judge noted that although the
    Circuit Court acknowledged that the prosecutor’s comments may
    have been improper, the Circuit Court also found that it was a
    reasonable strategy on the part of defense counsel not to object.
    Further, the Magistrate Judge, like the Circuit Court, concluded
    that “there [was] no possibility” that the State’s comments
    rendered the trial fundamentally unfair. Because of this, the
    Magistrate Judge found that Blackmon had failed to show that the
    state court’s rejection of this ineffective assistance claim was
    contrary to, or an unreasonable application of any of Strickland’s
    holdings.
    Blackmon timely objected to the Magistrate Judge’s R&R
    dispositions, including its recommendation that the District Court
    deny the two claims we consider here. 23 On March 5, 2018, the
    District Court overruled Blackmon’s objections to the R&R,
    adopted the R&R, and denied Blackmon’s petition for a writ of
    habeas corpus and his application for a certificate of appealability. 24
    Blackmon appealed the District Court’s decision and on April 22,
    2019, this Court issued a certificate of appealability on the two
    issues set out in the beginning of this opinion.
    23 Blackmon’s objections are quite rambling. The gist of his objections is that
    the Magistrate Judge failed to fully comprehend his claims.
    24 See 
    28 U.S.C. § 2253
    (c)(2).

    III.
    When reviewing a district court’s denial of a habeas petition,
    we review questions of law and mixed questions of law and fact de
    novo, and findings of fact for clear error. 25 See King v. Moore, 
    196 F.3d 1327
    , 1330 (11th Cir. 1999). The findings of fact the Circuit
    Court made in adjudicating Blackmon’s Rule 3.850 motion and the
    District Court considered in deciding Blackmon’s ineffective
    assistance of trial counsel claim are presumed “to be correct.” 
    28 U.S.C. § 2254
    (e)(1).
    We evaluate Blackmon’s ineffective assistance claims under
    the two-prong test set forth in Strickland. To prevail on an
    ineffective-assistance claim, the petitioner must show (1) that
    counsel’s performance was deficient and (2) that the deficient
    performance prejudiced the defense. 
    466 U.S. at 687
    , 
    104 S. Ct. at 2064
    .
    The performance prong is satisfied if the petitioner “show[s]
    that counsel’s representation fell below an objective standard of
    reasonableness.” 
    Id. at 688
    , 
    104 S. Ct. at 2064
    . Because “[t]here are
    countless ways to provide effective assistance in any given case,”
    
    id. at 689
    , 
    104 S. Ct. at 2065
    , “the range of what might be a
    reasonable approach at trial must be broad.” Chandler v. United
    States, 
    218 F.3d 1305
    , 1313 (11th Cir. 2000) (en banc). Thus, “a
    25 The District Court made no findings of fact in deciding the claims
    Blackmon’s § 2254 petition presented.
    USCA11 Case: 18-11416        Date Filed: 05/19/2022     Page: 24 of 29
    18-11416                Opinion of the Court                        24
    petitioner must establish that no competent counsel would have
    taken the action that his counsel did take.” Id. at 1315.
    The prejudice prong requires the petitioner to establish a
    “reasonable probability” that, but for counsel’s errors, the outcome
    at trial would have been different. Strickland, 
    466 U.S. at 694
    , 
    104 S. Ct. at 2068
    . “A reasonable probability is a probability sufficient
    to undermine confidence in the outcome.” 
    Id.
    With the foregoing principles in hand, we consider
    Blackmon’s arguments that the District Court erred in holding that
    the state courts’ adjudications of his claims of ineffective assistance
    of trial and appellate counsel were unassailable under 
    28 U.S.C. § 2254
    (d)(1) or (2). We start in subpart A where Blackmon began,
    with his assertion that appellate counsel should have assigned as
    error the trial court’s failure sua sponte to inform him of the
    dangers of joint representation (1) during the colloquy that took
    place prior to jury selection and (2) after Chester testified about the
    phone call that occurred between Earl and Blackmon during the
    robbery. Then, in subpart B, we consider Blackmon’s assertion
    that trial counsel should have objected to the prosecutor’s
    vouching of Chester’s testimony before the jury in closing
    argument.
    A.
    i.
    Although Blackmon stated in his habeas petition that he told
    the trial court, prior to jury selection, he was worried about
    Eagen’s ability to represent both himself and Earl, the trial
    USCA11 Case: 18-11416           Date Filed: 05/19/2022        Page: 25 of 29
    18-11416                  Opinion of the Court                              25
    transcript makes it quite clear that Blackmon’s concern centered on
    the consolidation of his and Earl’s trials, not joint representation.
    The trial court appropriately responded to Blackmon’s concern by
    explaining why Blackmon would not be prejudiced by a joint trial:
    because the State had charged Blackmon as a principal in the armed
    robbery, all of the evidence that would be introduced in Earl’s trial
    would be introduced in his as well. 26 Certainly nothing in this
    discussion would have suggested to the trial court that Eagen could
    not effectively represent both defendants. As the Magistrate Judge
    noted, Blackmon “had previously executed a waiver of his right to
    separate counsel.” And he had “agreed on the record . . .
    throughout the proceedings [that] he had assented to joint
    representation by Eagen.”
    In sum, the fact that Blackmon was concerned about a joint
    trial, not joint representation, fully supports the DCA’s rejection of
    this ineffective assistance claim. The DCA would have considered
    meritless appellate counsel’s argument that the trial court erred in
    failing sua sponte to inform Blackmon of the potential
    shortcomings of joint representation. Thus, counsel’s failure to
    26 In briefing this appeal, Blackmon focuses on whether his “waiver” of his
    right to separate counsel was adequate under the law. But this question is
    irrelevant for our purposes. The relevant question is whether the court had a
    duty to sua sponte advise Blackmon of the adverse consequences of joint
    representation based on the discussion that took place prior to jury selection.
    Because we conclude that the court was under no such duty, whether the
    “waiver” the prosecutor wanted the record to reflect was valid is
    inconsequential.

    raise it in briefing Blackmon’s appeal could not amount to
    ineffective assistance under Strickland.
    ii.
    The DCA likewise would have held meritless the same
    failure-to-inform argument based on Chester’s testimony during
    the prosecutor’s redirect examination about the Blackmon-Earl
    phone call. Eagen had just finished cross-examining Chester in an
    effort to cast doubt on whether Blackmon had truly acted as a
    lookout when the prosecutor asked Chester on redirect about the
    phone call (to which Eagen immediately objected unsuccessfully).
    Chester’s testimony about the phone call, according to Blackmon,
    somehow meant that Eagen could no longer represent both
    defendants competently, that Eagen was favoring Earl over
    Blackmon, and that the court had to intervene immediately.27
    Nothing in Eagen’s cross-examination of Chester, however, which
    obviously was in Blackmon’s best interests, would have suggested
    to the trial court that Eagen was favoring Earl over Blackmon and
    27 In his state habeas petition to the DCA, Blackmon also argued that after
    hearing Chester’s testimony, he decided that he wanted to testify but Eagen
    prevented him from doing so. In Blackmon’s mind, Eagen prevented him
    from testifying because Eagen felt that his testimony would be harmful to Earl.
    At no point in his habeas petition, however, did Blackmon suggest that the
    trial court was made aware of his desire to testify. The trial judge could not be
    charged with reading Blackmon’s mind, and he was not privy to any private
    conversations that may have taken place between Blackmon and Eagen. The
    law does not fault a judge for such limitations.

    that it had to excuse the jury and hold a hearing on the issue of joint
    representation. 28 Again, counsel’s failure to assert the failure-to-
    inform theory as trial court error in briefing Blackmon’s appeal
    could not amount to ineffective assistance under Strickland.
    B.
    We turn now to Blackmon’s claim that Eagen rendered
    ineffective assistance in failing to object to the prosecutor’s
    bolstering of Chester’s testimony in his closing argument to the
    jury. 29 The Circuit Court denied the claim following an
    evidentiary hearing in which Eagen testified. The DCA affirmed.
    In reviewing the DCA’s decision, the District Court “looked
    through” the DCA’s decision and reviewed the Circuit Court’s
    decision as Sellers instructs. 
    138 S. Ct. at 1188
    .
    Bolstering occurs when “‘the jury could reasonably believe
    that the prosecutor was indicating a personal belief in the witness’
    credibility.’” United States v. Knowles, 
    66 F.3d 1146
    , 1161 n.60
    (11th Cir. 1995) (quoting United States v. Sims, 
    719 F.2d 375
    , 377
    (11th Cir. 1983)). Because Chester’s testimony was so central to
    the State’s case, Blackmon argued, Eagen’s failure to object to any
    28 We are mindful of the principle that a trial court must initiate an inquiry
    into the propriety of joint representation when it “knows or reasonably should
    know that a particular conflict exists.” Cuyler v. Sullivan, 
    446 U.S. 335
    , 347,
    
    100 S. Ct. 1708
    , 1717 (1980).
    29 The prosecutor’s bolstering is set out in part I.B.
    USCA11 Case: 18-11416       Date Filed: 05/19/2022     Page: 28 of 29
    18-11416               Opinion of the Court                        28
    improper bolstering was a serious error and one that competent
    counsel would not have made. Without the bolstering, Blackmon
    continues, the jury likely would have acquitted him because “the
    state presented almost no other evidence of [his] guilt aside from
    Chester’s accusations.”
    The Circuit Court found no merit in Blackmon’s ineffective
    assistance claim. The Circuit Court noted that it had “heard a lot
    of defense attorneys talk about their different strategies in closing
    arguments. Many attorneys take the view, as Mr. Eagen did, that,
    in the absence of something very egregious, it’s simply better not
    to object and not call attention to the State’s closing.” Although the
    Circuit Court stated that the comments were probably improper,
    it still found that Eagen’s decision not to object did not constitute
    deficient performance under Strickland because “reasonable
    attorneys could differ on that strategy.” Given this finding, the
    Court logically concluded that Blackmon had failed to satisfy the
    Strickland performance test—that Eagen’s performance was so
    deficient that he was not functioning as the counsel guaranteed by
    the Sixth Amendment. See Strickland, 
    466 U.S. at 687
    , 
    104 S. Ct. at 2064
    .
    The Circuit Court was bound to reach that conclusion. The
    Supreme Court made clear in Strickland that “a court must indulge
    in a strong presumption that counsel’s conduct falls within the
    wide range of reasonable professional assistance; that is, the
    defendant must overcome the presumption that, under the
    circumstances, the challenged action ‘might be considered sound

    , 101,

    , 164 (1955)).
    This is so, the Supreme Court explained, because “[t]here are
    countless ways to provide effective assistance in any given case”
    and “[e]ven the best criminal defense attorneys would not defend
    a particular client in the same way.”

    The Trial for Life: Effective Assistance of Counsel in Death Penalty
    Cases, 58 N.Y.U.L. REV. 299, 343 (1983)).
    The District Court correctly concluded that Blackmon failed
    to establish that the DCA’s affirmance of this ineffective assistance
    claim constituted an adjudication that was “contrary to, or an
    incorrect application of,” the Supreme Court’s holdings in
    Strickland.
    IV.
    For the foregoing reasons, the judgment of the District
    Court is
    AFFIRMED.
