Dеfendant-Appellant Duane Hamilton appeals the District Court’s denial of his motion to withdraw his guilty plea and its decision to sentence him to 322 months’ imprisonment. We exercise jurisdiction under 28 U.S.C. § 1291 and AFFIRM.
I. BACKGROUND
In May 2006, pursuant to a plea agreement with the Government, Mr. Hamilton pleaded guilty to two counts: (1) possession of 50 grams or more of cocaine base (i.e., crack cocaine) with intent to distribute in violation of 21 U.S.C. § 841(a)(1) and (b)(l)(A)(iii); and (2) possession of firearms in furtherance of a drug trafficking offense (i.e., thе offense charged in count one) in violation of 18 U.S.C. § 924(c)(1)(A)®. The probation office prepared a presentence report classifying Mr. Hamilton as a career offender under § 4B1.1 of the U.S. Sentencing Guidelines (“Guidelines” or “U.S.S.G.”) based on two prior felony convictions of a “controlled substance offense.” U.S.S.G. § 4B1.1(a)(3); see also U.S.S.G. § 4B1.2(b) (defining “controlled substance offense”). Due to the application of the career-offender guideline, Mr. Hamilton’s criminal history category was VI. See U.S.S.G. § 4B1.1(b). After a three-lеvel reduction for acceptance of responsibility under U.S.S.G. § 3E1.1, the probation office reported Mr. Hamilton’s adjusted offense level as 34. Based on his criminal history category and offense level, the sentencing range calculated under the career-offender guideline was 322 to 387 months’ imprisonment. See U.S.S.G. § 4B1.1(c)(2)(A).
Before his sentencing hearing, Mr. Hamilton filed a motion to withdraw his guilty plea, arguing that he received ineffective assistance of counsel when he entered into the plea agreement and pleaded guilty. 1 Specifically, Mr. Hamilton argued that his attorney should have informed him that the court could impose a sentence between 322 and 387 months’ imprisonment under the career-offender guideline. See U.S.S.G. § 4B1.1(a), (c). He also argued that his attorney should have investigated his two prior felony convictions to determine whether they would, in fact, trigger application of the career-offender guideline. According to Mr. Hamilton, his attorney assured him that the court would likely impose a sentence at the statutory minimum for both counts, resulting in a total sentence of 15 years’ imprisonment. Mr. Hamilton argued he should be allowed to withdraw his plea because, if he had known that he faced a minimum of 26, rather than 15, years in prison under the Guidelines, he would not have pleaded guilty and would have insisted on going to trial.
Before ruling on Mr. Hamilton’s motion, the District Court held a hearing on the matter. At the hearing, Mr. Hamilton’s original counsel testified that he likely told Mr. Hamilton to expect a sentence between 15 and 16 years. He also acknowledged that he did not investigate the prior felony convictions or advise Mr. Hamilton of the effect the career-offender guideline could have on his sentence. As detailed in a previously filed affidavit, the attorney *1213 did not investigate these convictions or consider the career-offender guideline because Mr. Hamilton told him that one of the felony charges had been reduced to a simple possession charge, and if this were true, Mr. Hamilton could not be classified as a career offender. At the hearing, the attorney also testified that he did not promise Mr. Hamilton that he would receive a particular sentence and that Mr. Hamilton was aware of both the minimum statutory sentence of 15 years and the maximum statutory penalty of life in prison.
At the conclusion of the hearing, the District Court denied the motion, emphasizing that Mr. Hamilton had repeatedly represented to the court that he understood his sentence would be determined solely by the court and that he was knowingly and voluntarily entering his plea. After denying the motion, the court conducted a sentencing hearing, during which Mr. Hamilton asked the court to vary from the Guidelines to avoid a sentence that over-represented his criminal history and the seriousness of his offense. After listening to Mr. Hamilton’s arguments, the court decided to impose a Guidelines sentence. Although the court recognized that the Guidelines are not mandatory, it found them “instructive” and sentenced Mr. Hamilton to 322 months’ imprisonment, a sentence at the bottom end of the advisory Guidelines range. Mr. Hamilton challenges this sentence on appeal, as well as the District Court’s denial of his motion to withdraw his guilty plea.
II. DISCUSSION
A. Motion to Withdraw the Guilty Plea
1. Consideration of an Ineffective-Assistance Claim on Direct Appeal
Mr. Hamilton’s appeal of the District Court’s denial of his motion is largely based on his allegation that he received ineffective assistance of counsel. Ineffective-assistance claims should generally be brought in collateral proceedings, rather than on direct appeal, so that a factual record enabling effective appellate review may be developed in the district court.
United States v. Galloway,
2. Whether Mr. Hamilton Established a “Fair and Just Reason” for Withdrawal
Our review of a district court’s denial of a motion to withdraw a guilty plea is for abuse of discretion.
United States v. Kramer,
Under Fed.R.Crim.P. 11(d)(2)(B), a defendant may withdraw a guilty plea before the court imposes a sentence if “the defendant can show a fair and just reason for requesting the withdrawal.” The defendant bears the burden of establishing a “fair and just reason.”
United States v. Black,
a. Assertion of Innocence
Mr. Hamilton contends that he asserted his innocence on both counts in his motion to withdraw. As to the possession of crack cocaine with intent to distribute, he argues he asserted his “legal innocence” by claiming that the seizure of the drugs violated the Fourth Amendment. With respect to the firearms charge, he argues he asserted his innocence by claiming he did not possess the firearms “in furtherance of’ a drug trafficking crime as required by 18 U.S.C. § 924(c)(1)(A). We find both arguments unconvincing.
We begin by noting that a defendant may satisfy the assertion-of-innocence factor by asserting legal innocence. When Rule 32 (now Rule 11) was amended to require that the defendant show a fair and just reason for withdrawal, the Advisory Committee indicated that “whether the movant has asserted his legal innocence is an important factor to be weighed.” Fed. R.Crim.P. 32 Advisory Committee’s note to 1983 amendments;
see also United States v. Maxwell,
But although the assertion of legal innocence may satisfy this factor in some instances, the mere assertion of a legal defense is insufficient; the defendant must present a
credible
claim of legal innocence.
See Cray,
In the present case, Mr. Hamilton has not presented a factual argument in support of a Fourth Amendment defense to the drug offense. Instead, he emphasizes that, early in his case, he told his attorney to file a motion to suppress evidence, but his attorney did not do so. He also alleges that he received ineffective assistance of counsel at this time. But as we discuss below, Mr. Hamilton’s ineffective-assistance claim is based on his attorney’s conduct in determining his potential sentence. He makes no argument that his attorney was ineffective in not filing a motion tо suppress evidence on Fourth Amendment grounds. Indeed, he presents no argument in support of such a motion. Consequently, he has not effectively asserted his innocence as to the drug offense.
We reach the same conclusion regarding Mr. Hamilton’s assertion of innocence as to the charge of possession of a firearm in furtherance of a drug trafficking crime. See 18 U.S.C. § 924(c)(1)(A)(i). He argues that he is innocent of this offense because he did not possess the firearms “in furtherance of’ а drug trafficking crime. In specific support of this contention, he notes that he was not near his vehicle and was not distributing crack cocaine when the firearms and drugs were seized. These arguments do not, however, amount to assertions of factual or legal innocence.
First, Mr. Hamilton has not repudiated his admission of guilt or otherwise asserted that he is actually innocent of the underlying drug offense to which he pleaded guilty. This offense, possession of crack cocaine with intent to distributе,
see
21 U.S.C. § 841(a)(1), qualifies as a “drug trafficking crime” for purposes of the firearms charge.
See
18 U.S.C. § 924(c)(1)(A), (c)(2). Second, police found the firearms and drugs together in the same vehicle. This is sufficient proof that the firearms were possessed “in furtherance of’ the possession with intent to distribute.
See United States v. Trotter,
b. Ineffective Assistance of Counsel and Voluntariness of the Plea
Mr. Hamilton argues that he should be permitted to withdraw his plea because he received ineffective assistance of counsel when his attorney failed to inform him of the effect the career-offender guideline could have on his sentence. He also argues that his plea was not voluntary because he receivеd ineffective assistance. Our review of both questions — whether Mr. Hamilton received ineffective assistance of counsel and whether his plea was voluntary — is de novo.
See United States v. Orange,
When a defendant’s challenge to a guilty plea is based on ineffective assistance of counsel, we аpply the two-part test established in
Strickland v. Washington,
In this case, we need not decide whether the attorney’s performance was deficient because Mr. Hamilton has failed to show that he suffered prejudice as a result of his attorney’s representations regarding his potential sentence.
See Strickland,
In light of the court’s careful explanation of the plea’s consequences and Mr. Hamilton’s testimony that he understood those consequences, Mr. Hamilton’s allegation that he would have gone to trial but for his attorney’s failure to advise him of the career-offender provision is insufficient to establish prejudice.

See Gordon,
4 F.3d
*1217
at 1571 (holding that the mere allegation that defendant would have gone to trial but for counsel’s failure to warn him about the use of relevant conduct at sentencing was insufficient to establish prejudice);
see also Bethel v. United States,
c. Other Factors
Mr. Hamilton argues that the other four factors (prejudice to the government, timing of the motion, inconvenience to the court, and waste of judicial resources) weigh in his favor. Regarding the timing of his motion, even if the delay in filing was reasonable, as Mr. Hamilton argues, a reasonable delay is not a “fair and just reason” for withdrawal. In addition, given that Mr. Hamilton has not asserted his innocence or prevailed on his ineffective-assistance claim, his arguments concerning the remaining factors are irrelevant because these factors speak to the potential burden on the government and the court, rather than the defendant’s reason for withdrawal. That is, even if these factors weigh in a defendant’s favor, they cannot establish a fair and just reason for withdrawal.
Indeed, we have previously held that a court need not address рrejudice to the government unless a defendant presents a fair and just reason for withdrawal.

B. Sentence
Mr. Hamilton аlso appeals his sentence of 322 months’ imprisonment. We review a sentence imposed by a district court for reasonableness.
See United States v. Geiner,
Mr. Hamilton does not challenge the substantive reasonableness of his sentence.
5
Rather, he argues that the District Court used an improper procedure to determine his sentence. Although he does not take issue with the District Court’s calculation of his sentence under the Guidelines, he argues that the court erred by failing to explain how it considered the § 3553(a) factors.
See Geiner,
Because Mr. Hamilton raised no contemporaneous objection to the court’s explanation of the method for determining his sentence, we review only for plain error.
See Lopez-Flores,
As the Supreme Court recently explained, a sentencing court’s decision to apply a Guidelines sentence does “not necessarily require lengthy explanation.”
Rita v. United States,
— U.S. -,
*1219
Like the sentencing court in
Rita,
although the District Court did not specifically respond to Mr. Hamilton’s arguments for a variance, the “context and the record make clear” the court’s reason for rejecting his arguments.
Id.
at 2469. After listening to Mr. Hamilton’s arguments for imposition of a non-Guidelines sentence, the court explained that it was imposing a sentence under the career-offender guideline, U.S.S.G. § 4B1.1(c), and stated that it found the advisory Guidelines “instructive and helpful and informative” in this case. In other words, the record and context demonstrate that the court considered Mr. Hamilton’s arguments for a variance and rejected them because it determined that a Guidelines sentence is appropriate based on the particular facts of this case.
Cf. United States v. Cereceres-Zavala,
III. CONCLUSION
For the foregoing reasons, we AFFIRM the District Court’s denial of Mr. Hamilton’s motion to withdraw his guilty plea. We also AFFIRM Mr. Hamilton’s sentence.
Notes
. Mr. Hamilton was originally represented by counsel from the Federal Public Defender’s office. After he pleaded guilty, his counsel resigned from his position in the public defender's office, and a different attorney from the same office entered an appearance on Mr. Hamilton’s behalf. After reviewing Mr. Hamilton’s file, this attorney filed a motion to withdraw as counsel, noting that the original counsel had failed to inform Mr. Hamilton of his career-offender status. The court granted the motion and permitted the appointment of substitute counsel, who then filed the motion to withdraw the guilty plea.
. The D.C. Circuit has characterized the necessary showing of innocence аs a "viable claim,”
United States v. Hanson,
. We do not hold that a defendant who acknowledges the district court's sentencing discretion is necessarily precluded from demonstrating prejudice in every case. Rather, the proper inquiry is whether the defendant has *1217 shown that, but for his counsel’s conduct, he would not have pleaded guilty. Mr. Hamilton has not done so here.
. We do not suggest that these factors actually weigh in Mr. Hamilton's favor. A plea withdrawal inevitably results in some inconvenience to the court and waste of judicial resources.
See Carr,
. In his opening brief, Mr. Hamilton asserts that he is challenging his sentence of 322 months as unreasоnable in light of the seriousness of his offense and his criminal history,
see
§ 3553(a)(1), (2)(a). If Mr. Hamilton had supported this assertion with an argument, he would have raised a challenge to the substantive reasonableness of his sentence. But Mr. Hamilton has failed to make
any
argument in support of this assertion; instead, he focuses solely on the alleged procedural error, that is, the court’s failure to explain if and how it considered the § 3553(a) factors. Because he did not "make any argument or cite any authority to suрport his assertion,” Mr. Hamilton has waived the argument that his sentence is substantively unreasonable.
