Joseph Addai, Colts: Indianapolis has been dreadful running the ball the last few years and coaches are promising that will change. Addai, who has a nose for the end zone, could be a gem as a No. 2 back.
Marion Barber, Cowboys: He's notorious for wearing down as the season progresses. For whatever it's worth, Felix Jones (218 pounds) reported to camp heavier than Barber (214). That might tip the scales (ahem) in Jones' favor.
Cedric Benson, Bengals: Not only did Benson set a career high with 301 carries, his 4.2 yards per carry also was a personal best. Benson has never played a full season, so be sure to handcuff him with Bernard Scott. (Sorry, Bengals fans. Didn't mean to use Benson and "handcuff" in the same sentence.)
