I think of Payton, Sanders and Emmitt as the all time best. He isnt there yet.
But that leaves two spots in the top five, and it gets murky. But, I think you can make a strong case ADP deserves one of those two. This season is especially amazing, coming off the injury and putting up the largest numbers of his career.
Even if he starts to slow down some post-30, theres still a good chance he ends up he ends up ahead of Curtis Martin in all time rushing.
Bouyed by the fact that he'll probably run for 300 next sunday.
