1. Adrian Peterson, Oklahoma, 6-2, 218, JR:
Adrian Peterson will claim his status as the nation's top collegiate running back with Reggie Bush off to the NFL. There are some who feel Peterson would have been the top back in the country in 2006 even if Bush had remained with the Trojans for his senior season. Peterson signed with Oklahoma as an elite prep talent, and it didn't take him long to live up to the hype. As a true freshman, Peterson finished with an OU-record 1,925 rushing yards despite starting just eight games. He finished second in the Heisman voting as a true freshman, the highest any freshman has ever ranked in the Heisman polling.
Unfortunately, Peterson was hampered by an ineffective passing offense and injuries in 2005. With quarterback Jason White graduating, the Sooners were led into battle by Rhett Bomar, and opposing defenses were able to crowd the line of scrimmage. That slowed Peterson considerably, and a nagging ankle sprain was even more bothersome. The injury caused Peterson to miss all or more than half of four games in 2005. He still led all Big 12 backs with 1,024 yards and once again earned consensus All-Big 12 honors. He possesses a spectacular combination of size, speed, strength and is a natural, fluid runner who can change directions easily.
