Henry Alfred Thomas appeals the post-Booker ** sentence imposed by the district court upon his conviction for distribution of crack cocaine. See 21 U.S.C. § 841. He argues that the district court’s imposition of the maximum guideline sentence of 210 months was unreasonable in light of the Government’s motion for downward departure pursuant to U.S.S.G. § 5K1.1 based on his substantial assistance.

Thomas has failed to rebut the presumption of reasonableness afforded his properly calculated guideline sentence. United States v. Alonzo, 435 F.3d 551, 554 (5th Cir . 2006).

AFFIRMED.
