Peterson had a much higher yards per carry though, 5.6 vs Edge's 3.8 though.
Peterson's yard total would have been higher if he hadn't missed 2 games.
One can only speculate what Peterson might have done as a Cardinal. We are a totally different team than the Vikings. He might have been super or just average. What is done is done and it is time to move on an deal with what we have. The bigger problem in not getting AP, if that was a problem, it is who is the man selecting our players. He is still with us and will be for a long time if it is Graves. There perhaps is the greater problem.
