Top 25 Big Board

1. Calvin Johnson*, WR, Georgia Tech (6-4, 225) | previous: Same
He's not only a tremendous athlete, but he's a hard worker and very team oriented. Based on the needs of the Raiders and Lions, Johnson might not be the No. 1 overall pick, but he won't fall out of the top five.

2. Joe Thomas, OT, Wisconsin (6-6½, 313) | previous: Same
Huge, quick and athletic with a long wingspan.

3. Adrian Peterson*, RB, Oklahoma (6-1½, 218) | previous: Same
The most talented running back in the draft with an excellent burst to the outside for his size. The concern with Peterson is his durability.
