ORDER

Robert Leon was sentenced to a total of seventy-two months’ imprisonment and *426one year’s supervised release after he pleaded guilty to using a telephone to distribute crack cocaine. See 21 U.S.C. § 843(b). He was released from prison in May 2007 but tested positive for cocaine four times while on supervised release. His probation officer petitioned for revocation, and after a hearing the district court revoked the term and ordered Leon to serve another twelve months’ imprisonment. Leon appeals, but his appointed counsel moves to withdraw because he cannot identify any nonfrivolous argument to pursue. See Anders v. California, 386 U.S. 738, 744, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967). Leon has not accepted our invitation to respond to counsel’s submission. See Cir. R. 51(b). We confine our review to the potential issues outlined in counsel’s Anders brief. See United States v. Schuh, 289 F.3d 968, 973-74 (7th Cir. 2002).

Leon admitted the violations at his revocation hearing, and the only conceivable ground for appeal identified by counsel is whether twelve months is too much time. We will uphold a term of imprisonment imposed on revocation of supervision unless it is “plainly unreasonable,” a very narrow standard. United States v. Kizeart, 505 F.3d 672, 674-75 (7th Cir. 2007). In selecting an appropriate prison term to follow revocation, the district court must consider the policy statements in the guidelines, see U.S.S.G. ch. 7, pt. B, and the sentencing factors set out in 18 U.S.C. § 3553(a). United States v. Neal, 512 F.3d 427, 438 (7th Cir. 2008). In this case, the court acknowledged that Leon’s Grade B violation, see U.S.S.G. § 7Bl.l(a)(2), combined with his criminal history category of III, yielded a guidelines range of eight to fourteen months’ reimprisonment. U.S.S.G. § 7B1.4(a). The court then weighed the § 3553(a) factors, including the nature of the violations underlying the revocation, Leon’s history and characteristics, and the need for adequate deterrence to this type of violation. Thus, the court’s consideration of the guidelines and statutory factors was adequate, and we agree with counsel that any challenge to Leon’s term of reimprisonment would be frivolous.

We therefore GRANT counsel’s motion to withdraw and DISMISS the appeal.
