Allen was a third-team All-American selection as a junior safety when he recorded 123 tackles annd forced three fumbles.
After considering entering the 2005 draft, Allen decided to return for his senior season and started at cornerback for the first five games until he dislocated his left hip.
Without the injury, Allen probably would have been a top 10 pick. Reports suggested some teams had dropped Allen on their draft boards because of medical concerns, but Nick Saban said the Dolphins medical staff thoroughly checked him out and came away satisfied.
On top of that, Allen ran a 4.39 at the Scouting Combine.
Allen should start in the secondary in the 2006 season, but there's a question as to where he'll line up. Saban said Allen would be tried at various positions during next weekend's rookie minicamp and a decision would be made shortly thereafter.
Allen and Saban first met when Allen was in high school and Saban tried to recruit him to LSU. Saban didn't have any luck in getting him to LSU, but a few years later he got his man.
