Alabama running back Trent Richardson will be one of the top Heisman contenders this fall. Finally the Tide's feature back after two years as Mark Ingram's backup, Richardson racked up 134 yards from scrimmage in last Saturday's spring game.... Michigan's defense, ranked 110th overall last year, should improve, but its offense may struggle to adapt to new coach Brady Hoke's pro-style attack. Big Ten Offensive Player of the Year Denard Robinson did not look comfortable passing in the spring game, completing just 5 of 14 throws.... How loaded is Oklahoma? Coach Bob Stoops said the team's best defensive player this spring was sophomore-to-be Corey Nelson, the backup to potential All-America linebacker Travis Lewis. The Sooners figure to start the season at No. 1.
