Barry Sanders was the best running back I ever saw. Heck, the best football player I ever saw. Dude averaged 5 yards a carry and he never had anybody spectacular with him on offense. I have trouble even remember who the Quarterbacks and Wide Receivers are that played with him.
Jerry Rice - 2nd place, lol.
Note I never said that Barry Sanders was the best player you ever saw or anyone else ever saw. The best player I ever saw. The guy did amazing things with the ball in his hands, put up outstanding numbers without much of a supporting cast, and would have retired with many more records had he not retired so early.
I have nothing against Emmitt... one of the all-time greats, no question.
