Between now and the NFL combine (Feb. 21-27 in Indianapolis), there will be only slight changes to my Top 25 Big Board. The movement you see on the board is based on film evaluation from a player's career. Expect more movement and changes on the Big Board after the combine and individual workouts take place.

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: 5
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.

4. Brady Quinn, QB, Notre Dame (6-3½, 225) | previous: 3
Poised, smart and at his best in pressure situations. Quinn did throw two interceptions in the Sugar Bowl after throwing just one INT in his previous eight games.

5. JaMarcus Russell*, QB, LSU (6-6, 260) | previous: 4
Big, strong signal caller with a powerful arm, and his decision-making improved significantly in 2006.
