TD didn't receive a bunch of post career recognition because of his career ending injuries. I think it's widely accepted, had he played a full career (whatever that means), he would have been recognized as one of the top 3 professional running backs of all time, but wish in one hand and crap in the other.
GMAFB with that argument. Elway is a top ten QB with or without TD.
(Davis is my all time favorite running back)
