Alvin Kamara, one of the nation's top-rated prep running backs, announced Wednesday that he would play college football at Alabama. Kamara is a 5-foot-10, 192-pound senior at Norcross High School in Norcross, Ga. He had more than 1,500 yards and 20 touchdowns in 2012.

Kamara was undecided until Wednesday afternoon, when he picked Alabama over Georgia.

Kamara and defensive tackle A'Shawn Robinson of Fort Worth, Tex. both signed with the Crimson Tide on National College Signing Day 2013 after being largely undecided for months.
