This is something of a puzzling move. Lewis was told he'd be a third-round pick, but that might be a stretch. He doesn't have the best speed and is only listed at 5-foot-8 and 195 pounds.
He didn't live up to expectations this season after rushing for 1,799 yards in 2009. In 2010, he ran for 956 yards and 12 touchdowns in 11 games. He closed the regular season strong, rushing for 261 yards and four touchdowns against Cincinnati on Dec. 4.
