Adrian Peterson is by far the best running back in the NFL. The guy can just flat out play football. Not only is he strong and fast, but the way he finishes a run is amazing. He looks to punish the people trying to tackle him. For instance, check out this run he made today against the Steelers.
Notice he didn't just run over the guy. He then stepped on him as he took off down field. Adrian is very fun to watch. This guy is an awesome football player.
