*443¶1 Mr. Tyrus Lee Cooper moved the circuit court, prior to sentencing, to withdraw his guilty plea. The circuit court refused his request. Two years later, we disciplined his attorney (Michael J. Hicks) for professional misconduct that included his handling of Mr. Cooper's defense.1 Mr. Cooper believes our opinion in that disciplinary proceeding proved his counsel had provided ineffective assistance in his criminal case. That, he says, is a "fair and just reason" for withdrawing his plea. For the following reasons, we disagree.2
I. BACKGROUND
¶2 Mr. Cooper was charged with a single count of armed robbery as a party to a crime.3 The State Public Defender appointed Mr. Hicks to represent Mr. Cooper after the circuit court permitted his previous counsel to withdraw. Shortly afterwards, Mr. Cooper wrote to Mr. Hicks (in January of 2013) requesting a copy of discovery materials and raising concerns about his case-requests and concerns that he would repeat *444in subsequent letters. On October 8, 2013, which was approximately two weeks before his scheduled trial, Mr. Cooper personally wrote to the circuit court to claim that Mr. Hicks was interfering with his right to aid in his defense. He said Mr. Hicks had not provided him with a copy of the discovery materials and had failed to subpoena key witnesses. He also said he had not spoken to Mr. Hicks, by phone or in person, and therefore could not be prepared for trial.
¶3 Shortly before trial, the State offered to recommend a sentence of three years of initial confinement and three years of extended supervision if Mr. Cooper pled guilty as charged. He agreed, and on October 21, 2013, the circuit court heard his plea. Prior to accepting it, the circuit court4 confirmed that Mr. Cooper understood *195the plea agreement, maximum penalties, and elements of the charge. In response to the circuit court's questions, Mr. Cooper affirmatively asserted that he was aware of the constitutional rights he was waiving. The circuit court confirmed on the record that Mr. Cooper was of sound mind and capable of "freely, knowingly, and voluntarily"5 entering the plea.
¶4 The circuit court specifically asked Mr. Cooper about the allegations he made in his letter of *445October 8, 2013. Mr. Cooper stated that he wanted the circuit court to take "[n]o actions" with respect to the letter and indicated that he wanted the letter "disposed of." Mr. Cooper's final statement with respect to his plea was "I fully understand. I feel confident in what I did." The circuit court set sentencing for January 9, 2014.
¶5 Approximately three weeks before sentencing, Mr. Cooper personally sent another letter to the circuit court, this time asking to withdraw his plea "due to the fact of ineffective assistance of counsel." Mr. Cooper wrote that he was unaware that Mr. Hicks had been suspended from practicing law during part of his representation.6 And he claimed Mr. Hicks lied by failing to notify him of his suspension. He also said Mr. Hicks misled him into accepting the plea by stating he was destined to lose at trial. The circuit court allowed Mr. Hicks to withdraw as counsel and rescheduled the sentencing hearing.
¶6 Mr. Cooper's newly-appointed counsel formally moved to withdraw the plea. The motion asserts that the issues raised in the October 2013 letter were not resolved before the circuit court accepted the plea. It repeats many of the concerns Mr. Cooper listed in that letter, including that Mr. Hicks had not met with him from December 2012 until October 8, 2013, to discuss his case, and that Mr. Hicks failed to provide him with a copy of discovery materials. The motion *446also repeats the assertion that he had been unaware that Mr. Hicks' law license had been suspended. Finally, Mr. Cooper alleged that he did not knowingly and voluntarily enter his plea.
¶7 At the hearing on the plea-withdrawal motion, Mr. Cooper's new counsel said that if Mr. Cooper had known Mr. Hicks' license had been suspended, he would have asked for another lawyer. He also asserted that Mr. Cooper entered his plea in haste because he believed his attorney was not prepared for trial. However, Mr. Cooper's counsel also indicated that, if the circuit court granted his motion, Mr. Cooper might just enter the same plea because he was satisfied with the State's recommendation. Mr. Cooper testified at the hearing and claimed that he had believed part of the plea agreement included reducing the armed robbery charge to something with a lower maximum penalty. He did not say what he believed the reduced charge would have been. The circuit court questioned Mr. Cooper on this point, noting that the charge to which he pled had been read to *196him at the plea hearing, as well as its elements and the maximum penalty, and that he had affirmatively responded that he understood and wanted to enter his plea. Mr. Cooper said he thought the circuit court was required to read the original charge, but that he would actually be convicted of a lesser offense.
¶8 The circuit court denied Mr. Cooper's motion on June 27, 2014 (a date that will have some significance to our analysis). It concluded that the plea colloquy demonstrated that Mr. Cooper knowingly, intelligently, and voluntarily entered his plea, and that the matters in the October 8, 2013 letter had been properly addressed. It also concluded that granting Mr. Cooper's motion would cause substantial prejudice to *447the State. The circuit court made no factual findings regarding communications between Mr. Hicks and Mr. Cooper. In due course, the circuit court sentenced Mr. Cooper to five years of confinement and five years of extended supervision. Mr. Cooper appealed.
¶9 Two years after Mr. Cooper moved to withdraw his plea (and while his appeal was pending), we decided a disciplinary case brought by the Office of Lawyer Regulation (OLR) against Mr. Hicks. See In re Disciplinary Proceedings Against Hicks, 2016 WI 31, 368 Wis. 2d 108, 877 N.W.2d 848. After initially contesting the charges, Mr. Hicks withdrew his answer and filed a written "no contest" plea, agreeing that the referee could use the complaint's facts as a basis for identifying violations of the Rules of Professional Conduct for Attorneys.7 Id., ¶¶ 6-7. Based on that representation, the referee concluded that Mr. Hicks had engaged in nineteen acts of misconduct, including five that related to his representation of Mr. Cooper. Id., ¶¶ 6, 28.8 The OLR's complaint said that Mr. Hicks *448had failed to provide requested discovery documents to Mr. Cooper and failed to notify him and the circuit court of his *197license suspension for part of the time he was representing Mr. Cooper. Id., ¶¶ 23, 26. The complaint also said that Mr. Hicks did not discuss preparation for trial with Mr. Cooper, nor did he address the issues raised in Mr. Cooper's letters. Id., ¶¶ 23-24. Based on these facts, the OLR referee concluded, as a matter of law, that Mr. Hicks' misconduct "prevent[ed] [Mr. Cooper] from adequately understanding and participating in his own defense" in violation of SCR 20:1.4(a)(2).9 Hicks, 368 Wis. 2d 108, ¶ 28, 877 N.W.2d 848.
¶10 After reviewing the referee's report, we accepted his "factual findings as taken from the OLR's *449complaint." Id., ¶ 39. We also agreed "with the referee that those factual findings are sufficient to support a legal conclusion that Attorney Hicks engaged in the professional misconduct set forth in the 19 counts" contained in the OLR's complaint. Id.
¶11 On appeal, Mr. Cooper argued (in part) that our decision in Hicks established that he had received ineffective assistance of counsel prior to entering his guilty plea. The court of appeals considered the well-known analytical structure we use to assess such claims10 and concluded that Mr. Cooper had failed to show the allegedly deficient performance caused him prejudice. Therefore, the court of appeals affirmed the circuit court. State v. Cooper, No. 2016AP375-CR, unpublished slip op., 380 Wis.2d 508, 2018 WL 1100986 (Wis. Ct. App. Feb. 27, 2018).
¶12 We granted Mr. Cooper's petition for review, which presented the first and third of the following three issues. We asked the parties to brief the second issue:
1. When Cooper's counsel engaged in serious professional misconduct, preventing Cooper from adequately understanding and participating in his own defense, did this constitute ineffective assistance of counsel and provide Cooper with a fair and just reason to withdraw his guilty plea prior to sentencing?
2. In deciding whether Cooper may withdraw his guilty plea, is the circuit court bound by the Supreme Court's findings and/or conclusions in *450In re Disciplinary Proceedings Against Hicks, 2016 WI 31, 368 Wis. 2d 108, 877 N.W.2d 848 (2016), including, but not limited to, language stating that the failure of Cooper's trial counsel to properly communicate with him prevented him from adequately understanding and participating in his own defense ...?
3. Did the circuit court erroneously exercise its discretion when it denied defendant's motion to withdraw his plea prior to sentencing without a sufficient evidentiary record to support a finding that withdrawal of the plea pre-sentencing would result in substantial prejudice to the State?
For the reasons set forth below, we affirm the court of appeals.
II. STANDARD OF REVIEW
¶13 "[W]hether a defendant may withdraw his plea is left to the sound discretion of the circuit court." State v. Bollig, 2000 WI 6, ¶ 28, 232 Wis. 2d 561, 605 N.W.2d 199 (citation omitted). We review *198the circuit court's decision for an erroneous exercise of discretion. State v. Jenkins, 2007 WI 96, ¶ 30, 303 Wis. 2d 157, 736 N.W.2d 24. We will sustain an exercise of discretion if the circuit court "examined the relevant facts, applied a proper standard of law, and, using a demonstrated rational process, reached a conclusion that a reasonable judge could reach." Loy v. Bunderson, 107 Wis. 2d 400, 414-15, 320 N.W.2d 175 (1982).
¶14 "A claim for ineffective assistance of counsel is a mixed question of fact and law." State v. Wood, 2010 WI 17, ¶ 16, 323 Wis. 2d 321, 780 N.W.2d 63. We sustain the circuit court's factual findings "unless they are clearly erroneous." State v. Doss, 2008 WI 93, ¶ 23, 312 Wis. 2d. 570, 754 N.W.2d. 150. "Whether counsel's performance was deficient and prejudicial to his ...
*451client's defense is a question of law that we review de novo." State v. Hunt, 2014 WI 102, ¶ 22, 360 Wis. 2d 576, 851 N.W.2d. 434.
III. ANALYSIS
¶15 A court will generally grant a pre-sentencing request to withdraw a guilty plea upon presentation of a fair and just reason for doing so. State v. Canedy, 161 Wis. 2d 565, 582, 469 N.W.2d 163 (1991) ("The appropriate and applicable law in the case before the court, is that a defendant should be allowed to withdraw a guilty plea for any fair and just reason, unless the prosecution would be substantially prejudiced.") (emphasis omitted). This has been described as a "liberal rule" that fosters "the efficient administration of criminal justice" by "reduc[ing] the number of appeals contesting the 'knowing and voluntariness' of a guilty plea ...." Libke v. State, 60 Wis. 2d 121, 127-28, 208 N.W.2d 331 (1973). If the defendant establishes an appropriate reason by a preponderance of the evidence, Canedy, 161 Wis. 2d at 583-84, 469 N.W.2d 163, the State may nonetheless defeat the motion by proving substantial prejudice. Bollig, 232 Wis. 2d 561, ¶ 34, 605 N.W.2d 199.
¶16 The phrase "fair and just" is not, of course, susceptible to precise definition, and our cases have identified many reasons for withdrawing a plea that meet this standard. For example, an adequate reason "will likely exist if the defendant shows that the circuit court failed to conform to its statutory or other mandatory duties in the plea colloquy, and the defendant asserts misunderstanding because of it." Jenkins, 303 Wis. 2d 157, ¶ 62, 736 N.W.2d 24. See also *452Bollig, 232 Wis. 2d 561, ¶ 31, 605 N.W.2d 199 ("[I]f [the defendant] was unaware of his requirement to register as a convicted sex offender, he presented a fair and just reason for plea withdrawal."); State v. Shanks, 152 Wis. 2d 284, 290, 448 N.W.2d 264 (Ct. App. 1989) ("Genuine misunderstanding of a guilty plea's consequences is a ground for withdrawal.") (citation omitted). "[H]aste and confusion in entering the plea" is a fair and just reason for withdrawing a plea, as is "coercion on the part of trial counsel." State v. Shimek, 230 Wis. 2d 730, 739, 601 N.W.2d 865 (Ct. App. 1999) (citation omitted). Indeed, we have said that "the mere showing of some adequate reason for defendant's change of heart" will suffice. Canedy, 161 Wis. 2d at 583, 469 N.W.2d 163 (citation and internal marks omitted). But there are limits on the reasons we will accept as adequate. At a minimum, a "fair and just reason" must be something other than a bare desire to have a trial. Id.
¶17 Mr. Cooper says he should be allowed to withdraw his plea because he received ineffective assistance of counsel from Mr. Hicks before he pled. If true, that would certainly entitle him to relief because such a justification satisfies even the more rigorous post-sentencing "manifest *199injustice" plea-withdrawal standard. State v. Dillard, 2014 WI 123, ¶ 84, 358 Wis. 2d 543, 859 N.W.2d 44 ("One way to demonstrate manifest injustice is to establish that the defendant received ineffective assistance of counsel.").
A. Hicks as Proof of Ineffective Assistance of Counsel
¶18 The proof Mr. Cooper offers to establish the deficiency of his counsel is of no small moment, for he offers us the words of our own opinion in which we *453announced Mr. Hicks' discipline for his misconduct in handling Mr. Cooper's defense. Specifically, he says we conclusively answered the deficiency question when we addressed Count 13 of the OLR's complaint, which says:
By failing between the date on which he received [Mr. Cooper's] letter in January 2013 and February 12, 2013, between March 11, 2013 and August 16, 2013, and between August 18, 2013 and October 20, 2013, to communicate with [Mr. Cooper] regarding the issues raised in [Mr. Cooper's] January 2013 letter and to otherwise consult with [Mr. Cooper] regarding trial strategy and preparation, thereby preventing [Mr. Cooper] from adequately understanding and participating in his own defense, [Attorney] Hicks violated SCR 20:1.4(a)(2).
Hicks, 368 Wis. 2d 108, ¶ 28, 877 N.W.2d 848 (quoting OLR's complaint) (emphasis added) (some alterations in original). However, for the following three reasons, we conclude that our decision in Hicks has no material effect on the resolution of Mr. Cooper's case.
¶19 First, with respect to what we said in Hicks, there is a distinction to be drawn between our quotation of the OLR's complaint, on the one hand, and on the other our review of the referee's factual findings and our independent conclusions of law. We said we would accept the referee's "factual findings as taken from the OLR's complaint," id., ¶ 39, which means we must review the referee's findings of fact and the OLR complaint's allegations to determine whether we adopted the statement upon which Mr. Cooper relies. The factual background supporting Mr. Hicks' misconduct appears in paragraphs 52-62 of the OLR's complaint. The passage on which Mr. Cooper relies appears in paragraph 63, which is not part of the factual background *454but is the formal accusation of misconduct against Mr. Hicks. The referee's report tracked the complaint's distinction between the facts, on the one hand, and on the other the formal accusation of misconduct. Consequently, the referee's findings of fact do not contain the assertion that Mr. Hicks "prevent[ed] [Mr. Cooper] from adequately understanding and participating in his own defense ...." See Hicks, 368 Wis. 2d 108, ¶ 28, 877 N.W.2d 848. That statement appears in the referee's conclusions of law.11 So it cannot be said that we adopted the statement on which Mr. Cooper relies as a factual matter.
¶20 Nor could it be said that we adopted the referee's statement as a conclusion of law. Our analysis in Hicks started with the usual assertion that we "review the referee's conclusions of law on a de novo basis." Id., ¶ 38 (citation omitted). We did not deviate from that standard practice. Our terse conclusion did not comment on whether Mr. Hicks' misconduct interfered with Mr. Cooper's defense. Instead, we said we "agree with the referee that [the]
*200factual findings are sufficient to support a legal conclusion that Attorney Hicks engaged in the professional misconduct set forth in the 19 counts described above." Id., ¶ 39. The professional misconduct to which the complaint and referee referred in Count 13 was a violation of SCR 20:1.4(a)(2). So our conclusion of law, as relevant here, was that Mr. Hicks failed to "reasonably consult with the client about the means by which the client's *455objectives are to be accomplished ...." SCR 20:1.4(a)(2). The referee's statement that the misconduct had also "prevent[ed] [Mr. Cooper] from adequately understanding and participating in his own defense" had no necessary bearing on whether Mr. Hicks had violated SCR 20:1.4(a)(2). See Hicks, 368 Wis. 2d 108, ¶ 28, 877 N.W.2d 848. Our opinion did not specifically address that statement, analyze it, or in any other fashion suggest it was a conclusion we were adopting.12 Our conclusion went no further than a judgment that the referee's findings of fact described a violation of SCR 20:1.4(a)(2).13
¶21 The second reason Hicks does not stand for the proposition that Mr. Cooper received ineffective *456assistance of counsel bears a close relation to the first. Our purpose in Hicks was not to inquire into the validity of Mr. Cooper's guilty plea. It was to determine whether Mr. Hicks had engaged in professional misconduct. In particular, our inquiry into Count 13's allegations required us to go no further than considering the adequacy of Mr. Hicks' consultation with Mr. Cooper about the "means by which the client's objectives are to be accomplished." SCR 20:1.4(a)(2). Ineffective assistance of counsel, on the other hand, arises only when a defendant suffers prejudice as a result of his counsel's deficient performance. Strickland v. Washington, 466 U.S. 668, 687, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984) ; State v. Thiel, 2003 WI 111, ¶ 18, 264 Wis. 2d 571, 665 N.W.2d 305. Although it is possible for an attorney's misconduct to be so grave that it deprives a defendant of the effective assistance of counsel, the causal link between the two is not one of necessity, but of possibility. That is to say, it is possible that an attorney could violate SCR 20:1.4(a)(2) without running afoul of Strickland; not every violation of the Rules will rise to the level of ineffective assistance of counsel. That is so because the standards established by the Rules do not necessarily correlate exactly with those described in substantive areas of the law.
Violation of a rule should not itself give rise to a cause of action against a lawyer nor should it create any presumption in *201such a case that a legal duty has been breached.... Furthermore, the purpose of the rules can be subverted when they are invoked by opposing parties as procedural weapons. The fact that a rule is a just basis for a lawyer's self-assessment, or for sanctioning a lawyer under the administration of a disciplinary authority, does not imply that an antagonist in a collateral proceeding or transaction has standing to seek enforcement of the rule. Nevertheless, *457since the rules do establish standards of conduct by lawyers, a lawyer's violation of a rule may be evidence of breach of the applicable standard of conduct.
SCR Rules of Professional Conduct, Preamble, ¶20.
¶22 Therefore, our conclusion that Mr. Hicks failed to meet the demands of SCR 20:1.4(a)(2) cannot mean, ipso facto, that he performed deficiently within Strickland's meaning. More to the point, it may not be taken to mean we had specifically measured the impact of Mr. Hicks' violation of SCR 20:1.4(a)(2) on Mr. Cooper's ability to enter an appropriate plea. We simply did not address that subject, even tangentially. Nor could we have done so based on the record before us in Hicks. The OLR's complaint simply did not contain the information necessary for us to evaluate whether Mr. Hicks' performance was so deficient that it prejudiced Mr. Cooper's ability to knowingly, intelligently, and voluntarily enter a plea.
¶23 The third reason Hicks is uninstructive concerns its temporal relationship to this case. As we foreshadowed in our recitation of the procedural history, the date on which Mr. Cooper's motion was denied is important. We are reviewing the circuit court's exercise of its discretion, which necessarily means we focus on the facts available to the circuit court when it made its decision. Hartung v. Hartung, 102 Wis. 2d 58, 66, 306 N.W.2d 16 (1981) ("A discretionary determination, to be sustained, must demonstrably be made and based upon the facts appearing in the record and in reliance on the appropriate and applicable law."). We did not decide Hicks, of course, until almost two years after the circuit court denied Mr. Cooper's motion. And that means the referee's statement about the impact of *458Mr. Hicks' misconduct on Mr. Cooper's defense was not part of the record before the circuit court. We will not reverse a circuit court's discretionary decision based on facts outside of the record. Although there are mechanisms by which to challenge a court's judgment with facts discovered after its entry, Mr. Cooper does not engage them in this case. This is understandable because Hicks does not really present anything new, at least as it specifically relates to Mr. Cooper's plea (as we will discuss further below). For these three reasons, we conclude that Hicks has nothing instructive to say in evaluating whether the circuit court erroneously exercised its discretion when it denied Mr. Cooper's motion to withdraw his plea.
B. Hicks Adds Nothing to the Ineffective Assistance Analysis
¶24 Aside from the referee's statement regarding the effect of Mr. Hicks' misconduct on Mr. Cooper's defense (which we did not adopt), our opinion in Hicks suggests no additional support for Mr. Cooper's claim that he received ineffective assistance of counsel prior to entering his plea. To the extent the opinion bears on Mr. Cooper's case, it reflects that Mr. Hicks:
• had minimal communications with Mr. Cooper prior to the plea hearing;
• had not timely provided a copy of discovery material to Mr. Cooper; and *202• had not notified his client, the circuit court, or opposing counsel that his license to practice law had been suspended for part of the time he had been representing Mr. Cooper.
Hicks, 368 Wis. 2d 108, ¶ 28, 877 N.W.2d 848. The consequence of this misconduct, Mr. Cooper tells us, is that he acted with *459such haste and confusion in entering his plea that he genuinely did not understand its consequences. He also claims Mr. Hicks gave him misleading advice and coerced him into entering his plea.
¶25 All of these facts and allegations were already before the circuit court when it considered Mr. Cooper's motion to withdraw his plea. Thus, in January of 2014, Mr. Cooper personally wrote to the circuit court asserting that Mr. Hicks had misled him into pleading guilty and that Mr. Hicks had said Mr. Cooper was destined to lose at trial. His formal motion to withdraw his plea explained that the issues raised in his letter of October 8, 2013, had not been resolved. It also faulted Mr. Hicks for failing to disclose that his license had been suspended during part of the time the criminal case was pending. Finally, Mr. Cooper's motion claimed his plea was not knowing or voluntary, had been given in haste, and without sufficient consultation with his counsel or consideration of discovery materials.
¶26 At the hearing on his motion, Mr. Cooper once again asserted these deficiencies. He told the circuit court that he was confused regarding the charge to which he was pleading and the sentence range. He argued that Mr. Hicks had misled him about the nature of the charge, as well as the content of the plea agreement with the State. And he renewed his complaint about Mr. Hicks' lack of communication and his dissatisfaction with Mr. Hicks' failure to notify him of the temporary license suspension.
¶27 Our review of the record in this case, therefore, reveals that everything in Hicks relating to Mr. Cooper's defense had already been brought to the circuit court's attention before it decided the plea-withdrawal motion. Everything, that is, but for the *460referee's statement regarding the effect of Mr. Hicks' misconduct on Mr. Cooper's defense. But we are not bound by the statements of referees, and as we discussed above, we did not adopt the referee's statement as our own. Consequently, Hicks adds nothing relevant to the universe of facts that the circuit court was responsible for considering.
C. No Ineffective Assistance of Counsel
¶28 Hicks cannot do the work Mr. Cooper assigns to it. It does not, of its own force, establish that Mr. Hicks provided ineffective assistance of counsel. That leaves Mr. Cooper with the burden of showing: (1) "that counsel's performance was deficient"; and (2) "that the deficient performance prejudiced the defense." Strickland, 466 U.S. at 687, 104 S.Ct. 2052. This analytical structure applies specifically in the context of the plea process:
Although our decision in Strickland v. Washington dealt with a claim of ineffective assistance of counsel in a capital sentencing proceeding, and was premised in part on the similarity between such a proceeding and the usual criminal trial, the same two-part standard seems to us applicable to ineffective-assistance claims arising out of the plea process.
Hill v. Lockhart, 474 U.S. 52, 57, 106 S.Ct. 366, 88 L.Ed.2d 203 (1985). Even if we agreed that Mr. Hicks' misconduct rose to the level of deficient performance within the meaning of Strickland (a question on which we express no opinion), Mr. Cooper would nonetheless be unable to prove the prejudice element of the Strickland analysis. 14
*203*461¶29 In considering whether counsel's deficient performance prejudiced the defendant, we "evaluate whether 'there is a reasonable probability that, but for counsel's unprofessional errors, the result of the proceeding would have been different.' " State v. Sholar, 2018 WI 53, ¶ 33, 381 Wis. 2d 560, 912 N.W.2d 89 (quoting Strickland, 466 U.S. at 694, 104 S.Ct. 2052 ). When the alleged deficiency concerns the plea process, Hill says the prejudice component specifically requires that "the defendant must show that there is a reasonable probability that, but for counsel's errors, he would not have pleaded guilty and would have insisted on going to trial." Hill, 474 U.S. at 59, 106 S.Ct. 366. A probability sufficient to undermine confidence exists when there is "a 'substantial,' not just 'conceivable,' likelihood of a different result." Cullen v. Pinholster, 563 U.S. 170, 189, 131 S.Ct. 1388, 179 L.Ed.2d 557 (2011).
¶30 Determining whether a likelihood is substantial, as opposed to merely conceivable, can be a difficult undertaking when evaluating how an attorney's performance affects, for example, a jury's verdict, or the court's imposition of a sentence. We cannot, of *462course, reassemble and poll the jury to determine what it would have done in the absence of counsel's deficient performance. Neither do we return to the sentencing court to inquire into whether the sentence would have been different if counsel had performed better. Here, however, we need only know whether there is a substantial likelihood that Mr. Cooper would have pled differently if Mr. Hicks' performance did not fall below the Strickland standard. That information is, obviously, readily available to Mr. Cooper, and he had an opportunity to present it to the circuit court at the hearing on his motion to withdraw his plea. He did not comment, however, on whether his plea would have been different if Mr. Hicks had not performed as he did. To the contrary, his counsel said that "if the Court were to allow Mr. Cooper to withdraw his plea, he still might decide to enter a plea, because he does like-he's satisfied, I guess, with the recommendation that [the State] made." This does not describe a substantial likelihood of a different outcome. At best, it describes something conceivable. Therefore, he has shown no prejudice. Without prejudice, there can be no ineffective assistance of counsel. And because the ineffectiveness of counsel is the only "fair and just reason" Mr. Cooper gave for withdrawing his plea (at least in this court), his argument cannot prevail.15 *204*463¶31 The dissent is of a different mind. The author says: "I disagree with the majority opinion's conclusion that Mr. Cooper failed to allege that Attorney Hicks' deficient performance caused prejudice. Although Mr. Cooper's counsel stated at the hearing that Mr. Cooper still 'might' decide to enter a plea, Mr. Cooper is now asking this court to 'allow him to withdraw his guilty plea, and remand this case for further proceedings and a trial on the merits.' " Dissent, ¶38 (emphasis omitted). Our project here, of course, is reviewing whether the facts of record demonstrate "a 'substantial,' not just 'conceivable,' likelihood," Cullen, 563 U.S. at 189, 131 S.Ct. 1388, that Mr. Cooper would demand a trial. Although he conversed with the court at the hearing on his motion to withdraw his plea, he did not say he wanted to go to trial. To the contrary, his counsel told the circuit court that Mr. Cooper just might enter the plea again because he was satisfied with the State's recommendation.16
¶32 In any event, the dissent says, United States v. Davis, 428 F.3d 802, 808 (9th Cir. 2005), relieves defendants in Mr. Cooper's position of the obligation to even allege prejudice.17 The Ninth Circuit *464tried to reconcile its decision with Hill by distinguishing between pre-sentencing plea-withdrawal ( Davis ) and post-sentencing plea-withdrawal ( Hill ). It said that requiring a showing of prejudice in the former category would eliminate the distinction between the tests applied to each. Davis, 428 F.3d at 806. We disagree. The purpose of the "prejudice" component is to winnow the cases in which counsel's deficient performance would have no effect on the outcome of the proceedings: "This additional 'prejudice' requirement was based on our conclusion that '[a]n error by counsel, even if professionally unreasonable, does not warrant setting aside the judgment of a criminal proceeding if the error had no effect on the judgment.' " Hill, 474 U.S. at 57, 106 S.Ct. 366 (quoting Strickland, 466 U.S. at 691, 104 S.Ct. 2052 ) (alteration in original). We agree with Hill that Mr. Cooper cannot show prejudice unless "there is a reasonable probability that, but for counsel's errors, he would not have pleaded guilty and would have insisted on going to trial."

¶33 One final point bears mentioning. The dissent is embarking on a significantly different project from the one presented by this case. Our task here is to review the record of Mr. Cooper's criminal proceedings. The dissent, however, wants to create and review a hybrid record comprising Mr. Cooper's criminal case and Mr. Hicks' disciplinary proceedings. To further complicate matters, this hypothetical record did not become hybridized until after the circuit court completed its work, so the author is retroactively reading into the Cooper record information that was *205not available *465to the circuit court when the actions and decisions under review occurred. Making the dissent's proposed experiment in hybrid records even more problematic is the fact that one is criminal and the other is disciplinary. The differences between the two types of cases with respect to evidentiary standards, procedural safeguards, constitutional requirements, and interests of the different parties are too vast to catalogue here. Neither the dissent nor Mr. Cooper explain how we can iron out all of those differences in a way that would allow one record to rationally inform the other. Ultimately, the dissent's proposal to hybridize the record simply creates a path for collaterally attacking a criminal conviction via our attorney disciplinary proceedings. We are unwilling to blaze that trail.
IV. CONCLUSION
¶34 Our conclusions with respect to the three issues presented by this case are as follows. First, the record does not demonstrate that the professional misconduct described in Hicks prevented Mr. Cooper from receiving the effective assistance of counsel. Because that was the only rationale he offered (in this court) for withdrawing his plea, we conclude the circuit court did not erroneously exercise its discretion when it denied Mr. Cooper's motion. Second, we conclude that we did not adopt the referee's statement regarding the effect of Mr. Hicks' professional misconduct on Mr. Cooper's defense. And third, we need not determine whether the State would have been prejudiced if Mr. Cooper had been allowed to withdraw his plea because we conclude he did not present a "fair and just reason" for doing so.
By the Court. -The decision of the court of appeals is affirmed.
