    APPEAL FROM THE UNITED STATES DISTRICT COURT
    FOR THE NORTHERN DISTRICT OF OKLAHOMA
    (D.C. NO. 99-CV-00297-TCK-PJC)
    Jack Fisher, Fisher Law Office, Edmond, Oklahoma, and Paul S. McCausland,

    of Oklahoma, with her on the brief), Oklahoma City, Oklahoma, for Appellee.
    Before TYMKOVICH, GORSUCH, and PHILLIPS, Circuit Judges.
    TYMKOVICH, Circuit Judge.
    Jemaine Cannon was convicted in 1996 of murdering his then-girlfriend,
    Sharonda Clarke, and was sentenced to death. After a lengthy state appeals
    process, he filed a federal habeas petition in the Northern District of Oklahoma,
    which denied relief. In an appeal to this court in 2004, we concluded Cannon
    raised substantial questions about the performance of his trial and appellate
    counsel and remanded to the district court for further proceedings. We directed
    the court to consider whether Cannon’s counsel unconstitutionally (1) failed to
    investigate alleged contacts between jurors and prosecution witnesses and (2)
    denied him the right to testify at trial in his defense.
    The district court concluded that Cannon had not diligently pursued his
    claims relating to juror contacts in state court, denied his request for an
    evidentiary hearing on those claims, and denied relief. The court did, however,
    hold an evidentiary hearing on Cannon’s right-to-testify claim but ultimately
    denied relief after finding trial counsel had provided adequate assistance
    concerning the right to testify.
    Cannon raises two issues on appeal. First, he argues the district court erred
    in resolving his juror-contact ineffectiveness claims without an evidentiary
    hearing and in refusing to grant relief on those claims. We agree with the district
    court that Cannon was not diligent in developing the factual basis for these claims
    in state court and thus was not entitled to an evidentiary hearing. Given the
    resulting absence of any reliable evidence in the record showing that improper
    -2-
    contacts occurred, the district court did not err in denying relief on these claims.
    Cannon’s second argument is that the district court erred in finding that counsel
    (1) informed him of his right to testify, (2) did not prevent him from exercising
    that right, and (3) properly advised him as to the consequences of testifying. We
    find no error in the district court’s factual and legal conclusions on this issue.
    As a result, exercising jurisdiction under 
    28 U.S.C. § 2253
    , we AFFIRM.
    I. Background
    A. Factual Background
    Jemaine Cannon, who had recently escaped from custody for an unrelated
    assault conviction, stabbed his girlfriend, Sharonda Clark, to death on February 3,
    1995. When she was found more than twenty-four hours later, police discovered
    that she had been stabbed three times in the throat and once in the center of her
    chest. After the murder but before his arrest, Cannon spoke to his mother, telling
    her he had acted in self-defense and that Clark had fallen on the knife after she
    had attacked him. Although Cannon eventually turned himself in to police, he
    first called Tulsa police and provided an account of the attack to Detective Tom
    Fultz. In that conversation, Cannon admitted to stabbing Clark but claimed that
    he only did so after she attacked him and he snapped.
    A jury convicted Cannon of first-degree murder and sentenced him to
    death.
    -3-
    B. Procedural History
    After his conviction, Cannon appealed directly to the OCCA, which
    rejected all of his claims. He then petitioned that court for post-conviction relief,
    presenting a number of ineffective assistance of counsel claims concerning both
    trial and appellate counsel. Three of these claims are now at issue.
    In 1999, Cannon filed a petition for a writ of habeas corpus in federal
    district court, which the district court subsequently dismissed. Cannon then
    appealed to this court. We reversed the district court’s determination that
    Cannon’s failure to present his ineffective assistance claims on direct appeal, as
    required by Oklahoma law, meant that he was necessarily procedurally barred
    from raising those claims on federal habeas review. See Cannon v. Mullin
    (Cannon I), 
    383 F.3d 1152
    , 1174 (10th Cir. 2004). As we noted, a failure to
    comply with a state procedural rule requiring a petitioner to raise ineffective
    assistance claims on direct appeal will not always bar federal review. Such
    claims are only barred when the petitioner has had “an opportunity to consult with
    separate counsel on appeal.” 
    Id. at 1172
     (quoting English v. Cody, 
    146 F.3d 1257
    , 1259 (10th Cir. 1998)) (internal quotation marks omitted).
    Based on the record available in Cannon I, we found cause to believe that
    trial and appellate counsel were not separate because they both worked for the
    same federal public defender’s office. Nonetheless we noted that the district
    -4-
    court could hold an evidentiary hearing and allow Oklahoma an opportunity to
    establish otherwise. Id. at 1174.
    After determining that Cannon’s claims likely were not procedurally
    barred, we also considered whether he was entitled to an evidentiary hearing to
    establish his claim that certain state witnesses had improperly contacted his
    jurors. Id. at 1174–77. Pursuant to the Antiterrorism and Effective Death Penalty
    Act (AEDPA), a district court can only grant an evidentiary hearing when the
    petitioner has acted diligently in developing the state court record. See Williams
    v. Taylor, 
    529 U.S. 420
    , 432 (2000) (interpreting 
    28 U.S.C. § 2254
    (e)(2)). An
    evidentiary hearing was necessary to Cannon’s success on the juror-contact
    claims because—aside from a second-hand account contained in an affidavit from
    Cannon—nothing in the record hinted that any improper contacts had actually
    occurred. Despite their apparent availability, Cannon never provided the
    Oklahoma courts with affidavits, statements, or testimony from any of the family
    members or friends who allegedly witnessed the improper juror contacts. We
    noted in Cannon I that a “diligent person would have done as much, absent an
    impediment preventing him from doing so.” 
    383 F.3d at 1177
    . As a result, we
    remanded the issue to the district court with instructions to determine whether
    there were any such impediments excusing Cannon’s failure to develop the record
    that would thus entitle him to an evidentiary hearing on his juror-contact claims.
    We also concluded Cannon was entitled to an evidentiary hearing on his right to
    -5-
    testify because he had diligently developed the factual record underlying that
    claim by providing a first-hand affidavit to the OCCA.
    On remand, the district court found that trial and appellate counsel were not
    separate because of their close working and personal relationships. As a result,
    none of Cannon’s ineffective assistance claims were procedurally barred. But the
    court went on to find that Cannon was not entitled to an evidentiary hearing on
    the juror-contact issue because he was not diligent in developing the state court
    record and there were no impediments justifying this failure. Because there was
    no reliable evidence in the record of any improper juror contacts, the district court
    determined that both Cannon’s ineffective assistance of trial counsel and
    ineffective assistance of appellate counsel claims based on the alleged improper
    contacts were meritless.
    Finally, the district court turned to Cannon’s claim that trial counsel
    provided ineffective assistance concerning his right to testify. After review of the
    record, the court again found that Cannon had not met his burden of proving that
    counsel’s performance was in any way deficient.
    II. Analysis
    Cannon asserts two errors on appeal. First, he asserts both his trial and
    appellate counsel were deficient in pursuing his allegation that certain state
    witnesses improperly contacted jurors in his case, and that the district court erred
    on remand in denying an evidentiary hearing in which he could establish facts to
    -6-
    support these claims. Second, he argues the district court erred in finding both
    that trial counsel properly advised him concerning his right to testify and that
    counsel did not prevent him from testifying when he expressed a desire to do so.
    We consider each claim in turn.
    A. Improper Juror Contact
    Cannon raises two ineffective assistance of trial counsel claims concerning
    improper contacts between jurors and state witnesses. First, he says trial counsel
    ignored evidence he gave them regarding the improper contacts. He contends he
    had information from five friends and family members who observed several
    witnesses interacting with jurors. He claims his trial counsel were
    constitutionally ineffective for failing to pursue this information.
    Next, he claims his direct appellate counsel compounded the error by
    refusing to raise trial counsel’s ineffective assistance before the OCCA. Cannon
    argues he thus lost the opportunity for appellate review on a potentially
    meritorious claim.
    We agreed in Cannon I that the two ineffective assistance claims might
    have merit. But we were unable to review the substance of the claims because
    Cannon had yet to establish reliable evidence showing that any improper juror
    contacts actually occurred. As a result, we directed the district court to determine
    whether Cannon was entitled to an evidentiary hearing at which he would be able
    to supplement the record with evidence in support of his claims. But on remand,
    -7-
    the district court found Cannon had not been diligent in developing the factual
    record underlying his claim in state court and thus denied his request for an
    evidentiary hearing. More specifically, the court found no circumstances
    excusing his failure—on both direct and collateral review—to provide the
    Oklahoma courts with affidavits that might substantiate his claims.
    We review the district court’s legal conclusions de novo and its factual
    determinations for clear error. Fairchild v. Workman, 
    579 F.3d 1134
    , 1140 (10th
    Cir. 2009). We agree with the district court that Cannon was not entitled to an
    evidentiary hearing because he failed to diligently develop the record supporting
    his claims in state court. Because of this failure, there are no facts in the record
    from which we could conclude that any improper juror contacts occurred, much
    less that counsel performed deficiently in response to these alleged contacts.
    Accordingly, we must deny relief on this issue.
    1. Diligence
    Under AEDPA, a district court cannot hold an evidentiary hearing in a
    habeas proceeding if “the applicant has failed to develop the factual basis of a
    claim in State court proceedings.” 
    28 U.S.C. § 2254
    (e)(2). As the Supreme Court
    held in Williams v. Taylor, however, an applicant cannot be said to have “failed”
    to develop the factual basis of his claim “unless there is lack of diligence, or
    some greater fault, attributable to the prisoner or the prisoner’s counsel.” 
    529 U.S. at 432
    . Diligence, at a minimum, requires that an applicant both seek “an
    -8-
    evidentiary hearing in state court in the manner prescribed by state law,” and
    develop the record by submitting “evidence that would be readily available if the
    claim were true.” Cannon I, 
    383 F.3d at
    1176–77. 1
    In Cannon I, we concluded that Cannon had not yet demonstrated he had
    diligently developed the record underlying his improper juror-contact claims. The
    only evidence of improper contacts submitted to the Oklahoma courts was an
    affidavit from Cannon himself, and that affidavit did not assert any first-hand
    knowledge of the allegations. We noted that despite their apparent availability,
    Cannon never provided the Oklahoma courts with affidavits or statements from
    any of the family members or friends who allegedly witnessed the improper juror
    contacts. “A diligent person would have done as much, absent an impediment
    preventing him from doing so.” 
    Id. at 1177
    . The district court’s task on remand
    was to consider whether any legally significant impediments prevented Cannon
    from developing a record in state court on this issue.
    1
    Cannon cites Stouffer v. Trammell for the proposition that a mere
    allegation of improper juror contact automatically entitles a prisoner to an
    evidentiary hearing, regardless of diligence. See 
    738 F.3d 1205
    , 1220 (10th Cir.
    2013) (noting that the “proper remedy” for an allegation of jury tampering “is an
    evidentiary hearing”). Stouffer, however, cannot reasonably be read as
    establishing such a rule. Not only was the petitioner found to have been diligent,
    
    id. at 1219
    , but the court even explicitly stated that the petitioner “cannot receive
    a hearing if he ‘failed to develop the factual basis of [his] claim in state court,’”
    
    id.
     (quoting 
    28 U.S.C. § 2254
    (e)(2)). There is no special exception to the
    diligence requirement for improper contact cases.
    -9-
    The district court found Cannon was not diligent and rejected his request
    for an evidentiary hearing on the juror-contact claims. It found that Cannon was
    not diligent in developing the record on direct appeal because he never provided
    counsel with a list of potential witnesses and because he failed to prepare and file
    a pro-se request to supplement the record. The court found that Cannon also
    failed to act diligently during his state collateral proceedings because he failed to
    include first-hand witness affidavits in his application for post-conviction review.
    Cannon resists the district court’s conclusion for a number of reasons. As
    an initial matter, he restates an argument we rejected in Cannon I. He contends
    he satisfied the diligence requirement merely by requesting an evidentiary hearing
    in state court, submitting a personal affidavit detailing his juror-contact claims,
    and by seeking a similar affidavit from trial counsel prior to submitting his state
    application for post-conviction relief. But that argument is foreclosed by Cannon
    I, in which we concluded Cannon’s efforts were insufficient to establish diligence
    on the juror-contact claims unless he could show some kind of impediment
    excusing his failure to obtain eyewitness affidavits.
    Cannon thus presents two fall-back arguments for why we should excuse
    his failure to develop a reliable factual record in state court, and thus grant him an
    evidentiary hearing now. First, he argues that Oklahoma’s failure to provide him
    with separate trial and appellate counsel on direct review prevented him from
    raising the juror-contact issue in his initial appeal. Second, he says he was
    -10-
    prevented from developing a record on collateral review because his ineffective
    trial assistance claim was procedurally barred by OCCA rules.
    Although we assume for purposes of our review that the lack of separate
    counsel excuses Cannon’s failure to develop the record on direct appeal, we find
    there were no impediments that would prevent a diligent applicant from
    developing a reliable record on this claim during state post-conviction
    proceedings.
    a. Direct Appeal
    Cannon was represented by lawyers from the Tulsa federal defender’s
    office at both trial and on direct appeal. He argues that his appellate counsel’s
    failure to develop the record should not be attributed to him because trial and
    appellate counsel were not separate and the Constitution requires that criminal
    defendants have “an opportunity to consult with separate counsel on appeal in
    order to obtain an objective assessment of trial counsel’s performance.” English
    v. Cody, 
    146 F.3d 1257
    , 1263 (10th Cir. 1998). On remand, the district court
    found that although he had different lawyers at trial and on appeal, they were not
    legally separate because of their close personal and professional relationship.
    Because counsel were not legally separate, the district court concluded the
    ineffective assistance of trial counsel claim was not procedurally barred.
    Nonetheless, the court found the lack of separate counsel did not excuse Cannon
    of his obligation to develop the record.
    -11-
    Traditionally, the requirement that trial and appellate counsel be separate
    has been used to excuse a petitioner’s failure to bring an ineffective assistance
    claim on direct appeal. See, e.g., 
    id.
     (noting a lack of separateness trumps state
    procedural bar). We have yet to address whether the doctrine can also be used to
    excuse an appellant’s failure to develop the record relating to such a claim. We
    have, however, found that there are two concerns motivating the requirement of
    separateness between trial and appellate counsel: “First, a defendant, on his own
    as a layman, will ‘ordinarily be unable to recognize counsel’s errors and to
    evaluate counsel’s professional performance.’” Cannon I, 
    383 F.3d at 1173
    (internal citation omitted) (quoting Kimmelman v. Morrison, 
    477 U.S. 365
    , 378
    (1986)). “Second, a lawyer who renders ineffective assistance at trial will likely
    be hesitant to raise his own trial inadequacies on appeal, or even inform the client
    of any inadequacies.” 
    Id.
     Given these concerns, Cannon argues the district court
    erred in finding that he was still required to develop the record pro se on direct
    review concerning trial counsel’s failures despite the lack of separateness.
    Oklahoma argues that even though trial and appellate counsel were not separate,
    Cannon knew he had a potentially meritorious claim but failed to provide
    appellate counsel with the names of potential witnesses. The State also contends
    that nothing prevented Cannon from personally supplementing the record on
    direct appeal—Oklahoma law establishes a procedure by which criminal
    appellants can file pro-se pleadings with the OCCA and even move to supplement
    -12-
    the record. The district court agreed with both of Oklahoma’s arguments and
    found the lack of separateness did not excuse Cannon’s failure to develop the
    record on direct appeal.
    We need not decide whether Cannon’s knowledge of his potential claim
    combined with Oklahoma’s supplementation process makes him responsible for
    the failure to develop the record on direct review. 2 Nor do we address Cannon’s
    argument that he demonstrated sufficient diligence on direct appeal by bringing
    the juror-contact issue to his conflicted appellate counsel’s attention and that any
    failure to develop the record that occurred after that point is not attributable to
    Cannon. Rather, because we have determined that Cannon was not diligent in
    developing a record on collateral review, we assume for purposes of our
    discussion that a lack of separate trial and appellate counsel prevents us from
    attributing the failure to develop the record on direct appeal to Cannon.
    b. Collateral Review
    The district court also found that Cannon was not diligent because he failed
    to develop his ineffective assistance claim by submitting witness affidavits during
    the OCCA post-conviction process. We agree that his lack of diligence at this
    2
    Oklahoma points to Amos v. Roberts, 189 F. App’x 830 (10th Cir. 2006),
    as establishing a duty for defendants to file supplemental pleadings if possible
    under state law. But Amos only found that a petitioner could have raised
    supplemental claims on direct appeal in circumstances where he had conflict-free
    counsel. Amos never presented an ineffective assistance claim or a separateness
    challenge, so counsel’s failure to raise the defaulted claims was imputed to him.
    The court’s discussion of state pro-se procedures was superfluous to this point.
    -13-
    stage, even if he were diligent on direct appeal, cannot be excused under
    § 2254(e)(2). As a result, the district court did not err in denying Cannon’s
    request for an evidentiary hearing.
    Cannon presents several arguments challenging this conclusion. First, he
    argues that the diligence requirement does not apply at all to post-conviction
    proceedings. Second, he argues that requiring a pro-se petitioner to develop the
    record on post-conviction review violates the Sixth Amendment right to counsel
    and that, as a practical matter, his pro-se status prevented him from obtaining
    affidavits from family members who did not understand the importance of
    providing supplemental evidence in post-conviction proceedings. Finally, he
    contends that the OCCA’s improper procedural-bar finding—which precluded him
    from raising his ineffective trial-assistance claims on state collateral review—was
    an impediment that excuses his failure to develop the record on collateral review.
    i. Diligence in Post-Conviction Proceedings
    Cannon contends that diligence is only required on direct appeal and that
    lack of diligence at the post-conviction stage is immaterial. We disagree.
    First of all, nothing in the text of 
    28 U.S.C. § 2254
    (e)(2) distinguishes
    between appeals as of right and post-conviction proceedings—the statute simply
    requires that an applicant “develop the factual basis of a claim in State court
    proceedings.” 
    28 U.S.C. § 2254
    (e)(2). We see no obvious reason why AEDPA’s
    diligence requirement would apply only to direct appeals and not also to post-
    -14-
    conviction proceedings, especially when the post-conviction review involves legal
    errors not resolved on direct appeal. If anything, the policy of requiring
    petitioners to play all of their cards in state court is better served when prisoners
    have a second chance at demonstrating trial error and an opportunity to challenge
    errors made in the direct appeal. See Williams v. Taylor, 
    529 U.S. 420
    , 437
    (2000) (explaining the diligence requirement allows state courts “their rightful
    opportunity to adjudicate federal rights”). We note that this conclusion is in line
    with the Fifth Circuit’s finding in Dowthitt v. Johnson, which we cited favorably
    in Cannon I. Dowthitt v. Johnson, 
    230 F.3d 733
    , 758 (5th Cir. 2000) (finding that
    a petitioner was not diligent for failing to submit affidavits during state post-
    conviction proceedings); see also Lopez v. Ryan, 
    630 F.3d 1198
    , 1206 (9th Cir.
    2011); Koste v. Dormire, 
    345 F.3d 974
    , 985–86 (8th Cir. 2003); Alley v. Bell, 
    307 F.3d 380
    , 390–91 (6th Cir. 2002).
    We thus conclude 
    28 U.S.C. § 2254
    (e)(2) required Cannon to act diligently
    in developing the factual record during post-conviction review. Any other
    holding would deny the state its initial rightful opportunity to fully adjudicate the
    federal claims at issue. See Williams, 
    529 U.S. at 437
    .
    ii. Pro-Se Status and Developing the Record
    Next, Cannon argues that requiring a pro-se prisoner to develop the record
    during post-conviction review violates his Sixth Amendment right to counsel. In
    making this argument, Cannon points to the Supreme Court’s decision in Martinez
    -15-
    v. Ryan for the proposition that a pro-se prisoner is in “no position to develop the
    evidentiary basis for a claim of ineffective assistance, which often turns on
    evidence outside the trial record.” 
    132 S. Ct. 1309
    , 1317 (2011). In that case, the
    Supreme Court concluded that, where a state does not allow for ineffective trial
    assistance claims to be brought on direct appeal, ineffective assistance of
    post-conviction counsel can excuse a petitioner’s failure to bring a trial-assistance
    claim at that stage. 
    Id.
     at 1317–19. Cannon also points to Trevino v. Thaler, in
    which the Supreme Court extended Martinez to circumstances where it was
    “virtually impossible” to assert ineffectiveness claims on direct review because of
    obstacles created by state law. 
    133 S. Ct. 1911
    , 1915 (2013).
    Cannon argues that, because his trial and appellate counsel were not
    separate, his first realistic opportunity to raise his ineffective assistance claims
    was on post-conviction review. Citing the difficulty of investigating his claims
    from prison, which motivated both Martinez and Trevino, he argues that he could
    not have been required to develop the record pro se on post-conviction review.
    We see two problems with this argument. First, Oklahoma law, in contrast
    to the Supreme Court cases, grants defendants the right to an attorney for post-
    conviction challenges. As a result, petitioners are not required to develop either
    trial or appellate ineffective assistance claims on their own. And that is what
    happened here, at least initially. Cannon was provided appointed counsel through
    the Oklahoma Indigent Defense System for purposes of his post-conviction
    -16-
    appeal. See 
    Okla. Stat. tit. 22, § 1089
    (B) (1995). After several months, however,
    dissatisfied with appointed counsel, he insisted on representing himself. At a
    hearing to consider his request to go pro se, the trial court advised him to keep
    appointed counsel and detailed the problems with representing oneself from
    prison. Cannon insisted on proceeding pro se and the trial court reluctantly
    conceded Cannon was entitled to represent himself. Nonetheless, the trial court
    appointed stand-by counsel who was available to assist Cannon in investigating
    and presenting his application to the OCCA.
    In these circumstances, Cannon cannot refuse the assistance of counsel and
    then use his resulting pro-se status to argue that it would violate the Sixth
    Amendment to require him to develop the record. Nor has Cannon demonstrated
    how his confinement, as a practical matter, interfered in any particular way with
    his ability to obtain affidavits from his relatives and friends. As the district court
    found, Cannon did not need access to his legal files or records to obtain affidavits
    from his family members, and he never alleged any restrictions on his
    communications with them. In sum, Cannon’s pro-se status during post-
    conviction review does not excuse the requirement that he act diligently to
    develop the record.
    At oral argument, Cannon’s attorney advanced the theory that Cannon had
    diligently sought affidavits from eyewitness family members but that his relatives
    refused to accommodate him. In support of this contention, he referenced three
    -17-
    family-member affidavits he provided in support of diligence after our remand in
    Cannon I. In those affidavits his relatives asserted that Cannon had asked them to
    prepare affidavits for his state post-conviction application but they either were
    unable or refused because they did not understand the usefulness of additional
    evidence after completion of trial and direct appeal. 3 Cannon contends their
    reluctance constituted an obstacle excusing his failure to more fully develop the
    record and that the affidavits prove he was diligently attempting to develop the
    state court record.
    But Cannon did not pursue this argument in either his opening or reply
    brief to this court. Neither brief mentions that he previously requested affidavits
    from his family members, much less that his family members refused to provide
    them. This is especially problematic because the district court found that
    “Cannon’s diligence in obtaining the affidavits began in earnest only after the
    Tenth Circuit noted in its 2004 opinion that he had not provided affidavits from
    any of the alleged witnesses.” R., Vol. I, Doc. 222 at 9. The court also found “a
    reasonably diligent person would have been able to obtain the affidavits earlier”
    3
    We note that, despite claiming that they did not understand the value of
    providing affidavits after Cannon had already been convicted and lost his appeal,
    two of the affiants attended a post-conviction hearing at which Cannon sought to
    waive his appointed counsel.
    -18-
    because “each of the affiants states he or she was willing to testify at a hearing.”
    
    Id. at 11

    This court will not consider issues initially raised at oral argument. United
    States v. Irving, 
    665 F.3d 1184
    , 1210 n.23 (10th Cir. 2011) (issues raised for the
    first time in oral argument are waived); United States v. Rivera-Nevarez, 
    418 F.3d 1104
    , 1112 n.12 (10th Cir. 2005) (same). Not only is it “unfair to lie in wait until
    oral argument to present issues material to the appeal,” but “[r]aising [an] issue
    for the first time at oral argument affords the [opposing party] an inadequate
    opportunity to address it.” United States v. Almaraz, 
    306 F.3d 1031
    , 1040–41
    (10th Cir. 2002). Consequently, we decline to consider this argument as it has
    been waived.
    iii. Procedural Bar
    Finally, Cannon argues that the OCCA’s finding that his ineffective
    assistance of trial counsel claims were procedurally barred served as an
    impediment that prevented him from developing a record in post-conviction
    proceedings. Oklahoma does not seriously contest the notion that a procedural
    bar can serve as an impediment to factual development. Instead, the State argues
    that, due to the circumstances of this case, the procedural bar here did not prevent
    Cannon from submitting the contested affidavits and thus developing the record.
    4
    In the district court, Cannon only alleged that “Each [witness] had their
    own reasons for not providing affidavits to Mr. Cannon.” R., Vol. I, Doc. 216 at
    16.
    -19-
    As noted above, Cannon raised both of his ineffective assistance claims
    concerning improper juror contacts on state collateral review. Although the
    OCCA found Cannon’s trial-assistance claim was procedurally barred, it
    considered Cannon’s appellate-assistance claim on the merits. Ultimately, it
    rejected the appellate claim because Cannon failed to demonstrate that the juror-
    contact issue was any more meritorious than the claims his appellate counsel did
    raise.
    Cannon also petitioned the OCCA for an evidentiary hearing relating to his
    juror-contact claims. Because not all of Cannon’s claims were procedurally
    barred, the court considered this request on the merits but rejected it because
    Cannon’s personal affidavit did not establish by clear and convincing evidence
    that the testimony he sought to introduce was likely to be relevant. Oklahoma
    argues that Cannon could have submitted the contested affidavits as part of his
    application for an evidentiary hearing on his appellate-assistance claim.
    Given this contention, it is necessary to take a brief detour into Oklahoma
    post-conviction procedure. Under Oklahoma law, a petitioner in a capital case
    who wishes to supplement the record may file “an application for an evidentiary
    hearing, together with affidavits setting out those items alleged to be necessary
    for disposition of the issue petitioner is advancing.” R. Okla. Crim. App.
    9.7(D)(5) (1997). Affidavits from third-party witnesses may be submitted and
    considered under this rule and become part of the post-conviction record. See,
    -20-
    e.g., Slaughter v. State, 
    105 P.3d 832
    , 834–37 (Okla. Crim. App. 2005). The
    OCCA will only grant an evidentiary hearing when “[t]he application for
    evidentiary hearing and affidavits . . . ‘contain sufficient information to show . . .
    by clear and convincing evidence the materials sought to be introduced have or
    are likely to have support in law and fact to be relevant to an allegation raised in
    the application for post-conviction relief.’” 
    Id. at 835
     (quoting R. Okla. Crim.
    App. 9.7(D)(6)). 5
    And the record demonstrates that Cannon took advantage of these
    procedures. Acting pro se with standby counsel, he submitted a personal affidavit
    in support of his post-conviction application and requested an evidentiary hearing
    to further develop his claims. He also asked trial counsel to substantiate his
    juror-contact allegations but she refused, stating “I have no recollection of anyone
    talking with me about witnesses or anyone else making improper contact with
    jurors.” R., Vol. I, Doc. 218, Ex. 4. Nothing in the Oklahoma rules prevented
    him from attempting to obtain additional affidavits in support of his cause from
    family members, yet he failed to do so. After reviewing Cannon’s application and
    personal affidavit, the OCCA concluded he had not met his burden of showing by
    5
    Cannon argues he is entitled to an evidentiary hearing because
    Oklahoma’s Rule 9.7(D)’s “clear and convincing” standard is unconstitutionally
    strict. But whatever the statute’s shortcomings, it did not prevent Cannon from
    submitting the contested affidavits as part of his application to the OCCA. As we
    conclude, Cannon’s failure to submit these affidavits demonstrates his lack of
    diligence and thus precludes us from granting him an evidentiary hearing.
    -21-
    clear and convincing evidence that an evidentiary hearing would result in
    testimony likely to be relevant to his claims.
    We thus must agree with the district court that a diligent applicant would
    have submitted witness affidavits as part of his application for an evidentiary
    hearing. Cannon bore the burden before the OCCA of showing by clear and
    convincing evidence that the materials he wanted to add to the record were likely
    to support his claim that appellate counsel was ineffective. The affidavits could
    have established that appellate counsel never contacted the prospective witnesses.
    They also could have provided direct evidence that improper juror contacts
    actually occurred, bolstering the strength of both the ineffective trial assistance
    and appellate-ineffectiveness claims. This function is key, as the OCCA
    ultimately rejected Cannon’s appellate-assistance claim after finding that the
    claims appellate counsel did raise “were at least equally meritorious” to the
    omitted ineffective assistance of trial counsel claim. 
    Id.
     Doc. 216, Ex. 20 at 6.
    Finally, assuming that Cannon had been able to prove ineffective assistance of
    appellate counsel, he would have been given the opportunity to show the merits of
    his ineffective assistance of trial counsel claim. See Banks v. Reynolds, 
    54 F.3d 1508
    , 1516 (10th Cir. 1995) (applying Strickland v. Washington, 
    466 U.S. 668
    (1984)). 6 Evidence establishing that the improper contacts occurred would be
    6
    At the time of these post-conviction proceedings, the OCCA did not use
    the Strickland test for ineffective assistance claims, preferring its own standard
    (continued...)
    -22-
    necessary for Cannon to show that he was prejudiced by trial counsel’s
    performance.
    Given the obvious relevance of eyewitness testimony to Cannon’s claims,
    the hurdle he had to overcome to obtain an OCCA evidentiary hearing was
    establishing that he would actually be able to introduce such testimony at a
    hearing. As we said in Cannon I, a reasonably diligent person would not do as
    Cannon did and submit only a general hearsay affidavit claiming that such
    contacts occurred and that actual witnesses were willing to testify as to those
    contacts. This is especially true because the OCCA could easily interpret
    Cannon’s failure to submit additional information from his family and friends as
    evidence that no improper contacts actually occurred. Because Cannon should
    have submitted the disputed affidavits alongside his request for an OCCA
    evidentiary hearing on his appellate-assistance claim, the fact that he did not do
    so constitutes a failure of diligence that precluded the district court from granting
    6
    (...continued)
    from Walker v. State, 
    933 P.2d 327
     (Okla. Crim. App. 1997). This fact does not
    impact our analysis. Although Strickland and Walker differ in the showing
    required to prove ineffective assistance of appellate counsel, both end up in the
    same place if that showing is made: a full review of the omitted claim on the
    merits. Compare Banks, 
    54 F.3d at 1516
     (explaining that, under Strickland,
    “[a]ssuming [a petitioner] demonstrates ineffective appellate assistance, his
    procedural default will be excused and we may then review the merits of his
    claims”), with Cargle v. Mullin, 
    317 F.3d 1196
    , 1203 (10th Cir. 2003) (explaining
    that, under Walker, “[i]f ineffective assistance of appellate counsel is found in
    step two, the OCCA then proceeds to step three, where the omitted claim of trial
    error is fully reviewed on the merits”).
    -23-
    an evidentiary hearing. And to the extent he claims witnesses would not or could
    not submit affidavits during collateral review, he should have explained to the
    OCCA that these obstacles existed but that an evidentiary hearing would allow
    him to obtain the required evidence.
    The OCCA’s finding that Cannon’s ineffective assistance of trial counsel
    claim was procedurally barred does not undermine our conclusion. First, as we
    have already discussed and Cannon admits, both of his ineffective assistance
    claims—that is, his trial counsel and his appellate counsel claims—were
    dependent on the same underlying facts. See Aplt. Br. at 6–7.
    Second, the central purpose of the diligence requirement is to give state
    courts their initial “rightful opportunity to adjudicate federal rights.” Williams v.
    Taylor, 
    529 U.S. 420
    , 437 (2000). By failing to seize the opportunity to submit
    the juror-contact affidavits in support of his appellate counsel claim, Cannon
    denied the OCCA its rightful opportunity to consider and resolve both his
    appellate-assistance and his trial-assistance claims. This is because, had Cannon
    succeeded in showing ineffective assistance of appellate counsel, the OCCA then
    would have given his ineffective assistance of trial counsel claim a full merits
    review despite its earlier finding that the claim was procedurally barred. See
    Cargle v. Mullin, 
    317 F.3d 1196
    , 1203 (10th Cir. 2003). In other words, the
    procedural bar would not have prevented review of the trial-assistance claim had
    Cannon demonstrated ineffective appellate assistance. Therefore, it does not
    -24-
    matter that his ineffective trial and appellate counsel claims are distinct: a diligent
    petitioner would have presented facts demonstrating ineffective trial assistance as
    part of his ineffective appellate assistance claim.
    In sum, we agree with the district court that there were no impediments
    excusing Cannon’s failure to develop the record during his post-conviction
    proceedings. Because Williams requires that a petitioner show he diligently
    developed the record in state court in order to obtain an evidentiary hearing, see
    
    529 U.S. at 432
    , the district court did not err in denying Cannon’s request for a
    hearing.
    2. Merits
    Despite the lack of any reliable evidence of improper contacts in the state
    court record, Cannon argues that we can grant him relief on the merits even
    without granting an evidentiary hearing. After our remand in Cannon I, Cannon
    submitted to the district court affidavits from three family members asserting that
    improper juror contacts had, in fact, occurred. He argues that, although he was
    denied an evidentiary hearing, those affidavits are now part of the record and, as a
    result, we can consider them as evidence proving that improper contacts occurred.
    This argument, however, is foreclosed by Cargle v. Mullin, 
    317 F.3d at 1209
    . There, we found that 
    28 U.S.C. § 2254
    (e)(2) bars any documentary
    expansion of the record when the petitioner was not diligent in state court. See
    
    id.
     Because we conclude Cannon was not diligent in state court, we cannot
    -25-
    consider additional evidence outside the state court record. As we have already
    discussed, there is no reliable evidence in the record showing that improper
    contacts occurred. The district court was thus correct in dismissing both the trial
    and appellate juror-contact claims.
    B. Right to Testify
    Cannon also argues the district court erred in rejecting his claim that he
    was denied his Sixth Amendment right to testify. Unlike the juror-contact claim,
    the district court held an evidentiary hearing to resolve disputed facts.
    Every criminal defendant has the constitutional right to testify at trial and
    the ultimate decision of whether or not to testify belongs solely to the defendant.
    See Jones v. Barnes, 
    463 U.S. 745
    , 751 (1983). Defense counsel should inform
    the defendant of his right and that only he can decide whether or not to testify.
    United States v. Teague, 
    953 F.2d 1525
    , 1533–34 (11th Cir. 1992) (en banc).
    Counsel should also explain the strategic implications of testifying and whether or
    not they recommend that the defendant do so. Cannon I, 
    383 F.3d at 1171
    .
    Citing these principles, Cannon argues that his trial counsel failed to inform him
    of his right to testify and then prevented him from testifying when he expressed a
    desire to do so. He also argues they wrongly told him that certain damaging
    evidence would be admitted for impeachment purposes if—and only if—he were
    to testify. He thus argues his Sixth Amendment rights were violated because he
    did not make a knowing and voluntary waiver of his right to testify.
    -26-
    Demonstrating ineffective assistance of counsel requires a petitioner prove
    both that counsel’s performance was deficient and that he was prejudiced as a
    result. Strickland, 
    466 U.S. at 687
    . For deficient performance, the petitioner
    must show that counsel’s representation “fell below an objective standard of
    reasonableness.” 
    Id. at 688
    . “For counsel’s performance to be constitutionally
    ineffective, it must have been completely unreasonable, not merely wrong.” Boyd
    v. Ward, 
    179 F.3d 904
    , 914 (10th Cir. 1999). Prejudice requires a showing that
    there is a “reasonable probability that, but for counsel’s unprofessional errors, the
    result of the proceeding would have been different.” Strickland, 
    466 U.S. at 694
    .
    “A reasonable probability is a probability sufficient to undermine confidence in
    the outcome.” 
    Id.
     This requires that “[t]he likelihood of a different result must
    be substantial, not just conceivable.” Harrington v. Richter, 
    131 S. Ct. 770
    , 792
    (2011). 7
    After our remand in Cannon I, the district court held an evidentiary hearing
    on the Sixth-Amendment claims to resolve disputed facts. The court made a
    number of factual findings, including that trial counsel had informed Cannon of
    7
    Cannon argues that, although he has the burden of proof initially, he need
    only make a prima facie showing of ineffective assistance to shift the burden to
    the State, which then must rebut the inference that counsel was ineffective. In
    support of this theory, Cannon cites several cases dealing with race-based
    discrimination. See, e.g., Castaneda v. Partida, 
    430 U.S. 482
     (1977). Although a
    prima facie scheme makes sense for claims based on allegations of discrimination,
    where motive must be proved, it is not applicable to ineffective assistance claims.
    -27-
    his right to testify and had offered constitutionally adequate explanations of the
    implications of testifying. The court also found that counsel did not prevent him
    from testifying and, in any event, Cannon was not prejudiced by his failure to
    testify because he would not have offered credible testimony in his defense.
    Although our review of the district court’s legal analysis is de novo, Fairchild v.
    Workman, 
    579 F.3d 1134
    , 1140 (10th Cir. 2009), we must acknowledge the
    background principle that “counsel is strongly presumed to have rendered
    adequate assistance.” Strickland, 
    466 U.S. at 690
    . We review factual findings for
    clear error when they are the result of an evidentiary hearing. Douglas v.
    Workman, 
    560 F.3d 1156
    , 1170 (10th Cir. 2009).
    1. Strickland Deficient Performance
    Cannon contends that counsel’s performance was deficient because they
    failed to inform him of his right to testify, prevented him from testifying when he
    attempted to do so, and wrongly told him that certain damaging evidence would
    be admitted for impeachment purposes if he were to testify. The district court
    found that Cannon failed to establish the factual predicate of his first two
    contentions, and that counsel’s advice concerning the impeachment evidence was
    legally correct.
    Our independent review of the record finds no reason to supplant either the
    district court’s factual or legal findings.
    -28-
    a. Right to Testify
    At the evidentiary hearing, Cannon testified that trial counsel did not
    inform him of his right to testify and that they prevented him from testifying at
    trial when he attempted to do so. Although neither of Cannon’s counsel could
    explicitly remember telling Cannon about his right to testify, both testified that
    they did recall discussing the pros and cons of testifying with Cannon and both
    stated they always and without exception inform clients of the right to testify.
    Both also denied preventing Cannon from testifying.
    The district court found that Cannon’s testimony was not credible for a
    number of reasons. The court found that Cannon’s testimony contradicted other
    evidence and his own earlier statements, and that he was evasive on cross-
    examination and had an overly selective memory when it came to helpful and
    harmful facts. Given his extensive involvement in his defense, the court also
    found it unlikely that Cannon would have passively accepted any attempt to
    prevent him from testifying. “Credibility, of course, is a matter for the district
    court, not this court.” United States v. Draper, 
    24 F.3d 83
    , 85 (10th Cir. 1994).
    “[O]nly the trial judge can be aware of the variations in demeanor and tone of
    voice that bear so heavily on the listener’s understanding of and belief in what is
    said.” Anderson v. Bessemer City, 
    470 U.S. 564
    , 575 (1985). As a result, a trial
    judge’s “decision to credit the testimony of one of two or more witnesses, each of
    whom has told a coherent and facially plausible story that is not contradicted by
    -29-
    extrinsic evidence, . . . can virtually never be clear error.” 
    Id.
     Having
    determined that Cannon was not credible, the district court considered the
    testimony of trial counsel and concluded Cannon had not met his burden of
    proving that counsel provided ineffective assistance concerning his right to
    testify.
    In resisting the district court’s conclusions, Cannon first argues that
    because neither of his lawyers could specifically remember informing him of his
    right to testify, the district court necessarily erred by refusing to accept his
    uncontroverted testimony to the contrary. We disagree. Both of Cannon’s
    lawyers testified that they always and without exception informed defendants of
    their right to testify and we find no error in the district court’s decision to credit
    trial counsel’s testimony on this point. In response, Cannon argues that counsel’s
    testimony concerning their standard practices should not have been assigned
    significant weight because, in normal circumstances, the testimony would not
    have been admissible under Federal Rule of Evidence 406. 8 Rule 406 allows the
    admission of evidence concerning habits or routine practices, provided that
    sufficient foundation has been laid to establish their consistent application. More
    specifically, Cannon objects that neither of his attorneys testified as to how many
    8
    Because he elicited the testimony, Cannon does not challenge its
    admission, only its weight.
    -30-
    trials she had participated in, thus depriving the court of the ability to determine
    whether the claimed habit should be given any weight.
    Again, we cannot find that the district court clearly erred in its decision to
    credit trial counsel’s testimony over Cannon’s. Both attorneys were experienced
    public defenders, one of whom is the head of capital litigation with the Tulsa
    County Public Defenders Office and has been with that office since 1987.
    Cannon’s other attorney worked with that same office for over ten years. Given
    (1) their backgrounds and experience, (2) the presumption that counsel rendered
    adequate assistance, Strickland, 
    466 U.S. at 690
    , and (3) the district court’s
    finding on credibility, Cannon has not established that counsel failed to inform
    him of his right to testify.
    We likewise reject Cannon’s challenge to the district court’s finding that he
    failed to prove trial counsel thwarted his attempts to testify. Both of Cannon’s
    trial counsel unequivocally denied telling him that he could not testify and denied
    preventing him from doing so. One even confirmed this point in a letter she sent
    to Cannon during the post-trial appeal in which she stated, “I cannot swear out an
    affidavit claiming I would not let you testify, because I never told you that you
    couldn’t testify and I don’t recall you informing me you wanted to testify.” R.,
    Vol. I, Doc. 218, Ex. 4. The district court also reasonably found Cannon was
    engaged in his defense and would not have passively accepted a refusal to allow
    him to testify had it occurred. In short, we see no reason to overturn the district
    -31-
    court’s decision to credit counsel’s testimony that Cannon knowingly and
    voluntarily declined to testify, 9 and reject Cannon’s testimony to the contrary.
    b. Advice of Counsel
    Cannon’s second example of deficient performance is his claim that counsel
    incorrectly told him that if he testified he would be impeached with evidence
    showing a prior conviction for assault and with details of his recent escape from
    lawful custody. More specifically, Cannon had been convicted of assault and
    battery with intent to kill in 1991; a conviction which earned him a fifteen-year
    prison sentence. While serving that sentence, and shortly before his arrest in this
    case, Cannon escaped from Oklahoma Department of Corrections custody while
    participating in a work program. Cannon claims counsel incorrectly told him
    these facts would be admissible if he testified.
    In addition, Cannon claims counsel entered an agreement with the
    prosecutor in which the state agreed it would not introduce evidence of the prior
    conviction or escape unless Cannon testified. He contends he was never informed
    of this agreement and that this prevented him from knowingly and voluntarily
    waiving his right to testify.
    9
    Cannon also tangentially argues a waiver of the right to testify is
    ineffective unless made on the record. Nothing in this circuit, or any other,
    however, requires defendants to waive their right to testify on the record and we
    decline to adopt such a rule now. To the contrary, requiring judges to question
    each non-testifying defendant about his decision not to testify may result in
    defendants feeling pressured to give up their right not to testify. See United
    States v. Pennycooke, 
    65 F.3d 9
    , 13 (3d Cir. 1995).
    -32-
    The district court found that counsel provided effective assistance when
    they told Cannon that his prior conviction would be admissible. Under Oklahoma
    law, a prior felony conviction is admissible for its impeachment value if its
    “probative value of the evidence outweighs its prejudicial effect.” Cline v. State,
    
    782 P.2d 399
    , 400 (Okla. Crim. App. 1989). In making this evaluation, the court
    considers: “1. The impeachment value of the prior crime; 2. The point in time of
    the conviction and the witness’ [sic] subsequent history; 3. The similarity
    between the past crime and the charged crime; 4. The importance of the
    defendant’s testimony; and 5. The centrality of the credibility issue.” 
    Id.
     The
    district court concluded the prior conviction would have been admissible for
    impeachment.
    We agree. Factors two and five point in favor of admissibility. The prior
    crime was, at the time of the trial, relatively recent and Cannon’s credibility was
    crucial for the jury to assess whether or not it believed his self-defense argument.
    Factors one and four cut both ways. Although the relationship between a crime of
    violence and truthfulness is somewhat attenuated, the OCCA has repeatedly
    upheld the introduction of assault and battery convictions for their impeachment
    value. See, e.g., Shipman v. State, 
    639 P.2d 1248
     (Okla. Crim. App. 1982)
    (defendant charged with first-degree manslaughter); Campbell v. State, 
    636 P.2d 352
     (Okla. Crim. App. 1981) (defendant charged with first-degree murder). As
    for factor four, although Cannon’s testimony was naturally important, he was able
    -33-
    to introduce his version of events through other witnesses without testifying.
    Factor three cautions against admissibility. At bottom, competent counsel could
    conclude the evidence would likely be admitted on cross-examination if Cannon
    testified. Moreover, the damage the evidence would cause militated toward the
    strategy chosen—Cannon would not testify and his theory of self-defense would
    come in through the testimony of a police detective who spoke to Cannon before
    his arrest.
    Counsel’s advice on Cannon’s escape presents an easier question.
    Cannon’s own recorded statement indicated that he was afraid that the victim
    planned to turn him in to police once he left her apartment. The escape would
    have been admissible as evidence of Cannon’s motive to kill Ms. Clark.
    Of course, motive evidence could have been introduced even without
    Cannon testifying in his defense. But his counsel were able to enter into an
    agreement with the prosecution by which the state would not attempt to enter
    evidence of the escape or the prior conviction unless Cannon testified. Cannon
    asserts that he was never informed of this agreement and argues that counsel’s
    failure to tell him about it prevented him from making a knowing and voluntary
    waiver of his right to testify. But Cannon was correctly informed that if—and
    only if—he chose to testify, the state would seek to admit evidence of his prior
    felony and escape, and would likely be successful in doing so. Even if he were
    not informed of the details of any agreement, his counsel provided
    -34-
    constitutionally sufficient advice for him to knowingly evaluate his right to
    testify.
    In sum, we cannot conclude that counsel’s performance was
    constitutionally deficient or that Cannon’s waiver was involuntary. He was
    adequately informed of the consequences that would result from testifying.
    2. Strickland Prejudice
    Even though Strickland requires that Cannon establish both deficient
    performance and prejudice to obtain relief, having found no deficient
    performance, the district court went on to evaluate whether he was prejudiced by
    his failure to testify. For completeness, we review that conclusion.
    Prejudice requires a showing that there is a “reasonable probability that, but
    for counsel’s unprofessional errors, the result of the proceeding would have been

    The district court concluded that Cannon was not prejudiced by his failure
    to testify at trial because “his [evidentiary hearing] testimony was so
    untrustworthy and so inconsistent with other credible evidence that it was not
    substantially likely his testimony would have changed the result of the trial.” R.,
    Vol. I, Doc. 300, at 34. The court went on to state that “Cannon’s inability to
    -35-
    handle cross-examination—his evasive and uncooperative demeanor—would have
    rendered him a wholly ineffective witness.” 
    Id.
     The court also found that
    Cannon’s account of the murder “strain[ed] credulity beyond reasonable limit.”
    
    Id.
     Finally, the court noted that, had Cannon testified, his prior conviction and
    potentially his escape from custody would have come into evidence, further
    harming his defense.
    Cannon advances a number of objections to these conclusions. In
    summary, he contends the district court erred in finding that his testimony at the
    evidentiary hearing was inconsistent with his prior tape-recorded statement to a
    police detective. As Cannon explains it, the recorded conversation gives only a
    partial version of events. He says his testimony only deviated from the tape
    because he was filling in the blanks. He further argues that, where his testimony
    was contradicted by other evidence, the inconsistencies were inconsequential.
    We have reviewed all of Cannon’s objections to the district court’s
    credibility finding and see no error. Suffice it to say, the inconsistences between
    the record evidence, including his recorded statement, and his evidentiary hearing
    testimony support a conclusion that Cannon would not have advanced his cause
    by testifying at trial. Nor do we find any error in the district court’s conclusion
    that Cannon was evasive on cross-examination. For the reasons set forth by the
    district court, Cannon cannot show he was prejudiced by his failure to testify at
    trial.

    III. Conclusion
    The district court’s denial of Cannon’s petition for a writ of habeas corpus
    is AFFIRMED.
