As a pure runner, he's a great talent. Definitely one of the best to come along in years. He's not as dynamic, explosive, or versatile as Reggie Bush, but he might be the best pure runner since Tomlinson. He has rare breakaway speed and very good acceleration. He has good athletic instincts and balance. He doesn't have great lateral agility, but he's plenty quick. That's the good news. The bad news is that his frame is far from ideal. Whereas Tomlinson is built low to the ground with stocky legs, Peterson is a tall back who looks a little bit lean (almost like a WR). He's a big target for tacklers and he really takes some monster shots. Unlike Tomlinson, he doesn't appear to have a knack for protecting his body and avoiding unecessary collisions. With his long legs and upright style, he seems like an above average risk for serious injuries. Also, he's not very proven as a receiver. If he fails to develop in that category then his value could be somewhat limited. Bottom line is that he's a great talent. He has most of the skills you look for in an elite back. The only real flaws are his build and running style. If he was three inches shorter with a stockier build, then he'd be the perfect prospect. As it stands now, he's merely a great prospect whose career could be hampered and ultimately shortened by injuries resulting from his build and playing style. He also might struggle on a team with a weak supporting cast. He's not the niftiest back behind the line of scrimmage, which means he'll need an adequate run-blocking line in order to reach his full potential.
