 In his first three seasons at Ohio State he played behind three-time All American Mike Doss, seeing action on the field primarily in nickel coverage on passing downs.Allen is perhaps best remembered among college football fans for two plays made during the 2002 BCS national championship season.The first occurred during the 2002 Ohio State-Michigan game, intercepting a pass from Michigan quarterback John Navarre during the closing seconds to preserve the 14-9 victory and an undefeated regular season.
