Hands down the best RB in the history of the NFL IMO. Just an awesome football player. Class act too (except for the way he retired). His college stats are unreal.
Lots of people had problems with Saunders. Sure he was a yardage machine, comparable but not better than other great backs, but he also was missing some key intangibles he never proved he had.
He had some obvious flaws. One, he wasn't physical, which is huge in the playoffs. Emmitt did it on the regular, Saunders didn't, and that's only comparing him to his peers of that era, not even getting to other great backs. Without that physicality it's hard to come through with tough yards in the playoffs. He never had that. Second, his wasn't consistent, and most knew it-50 yard runs + 7 plays for no gain doesn't move the chains.
In other words, he made some great highlight films involving long runs, that he could watch over and over again while missing the playoffs. Never proved he was a big-time playoff back, didn't have those tools, wasn't tough and was of no value in short yardage.
