Adrian Peterson all the way
Adrian is a better running back. Reggie is a better reciever, especially a slot receiver. Reggie doesn't play reciever, though. So at the position they both play, running back, Adrian Peterson is a better player.
i would say they're about equal but if someone was better it would be Peterson
That is a matter of ones own opinion. Some people may think Chris Johnson is better. While others may think Adrian Peterson is better.
Peterson is better statistically, but turner is a better goal-line runner and gets more touchdowns. all in all i'd take Peterson
