If you guys think that Barry Sanders was a better running back than Emmitt Smith, then you really don't have a high understanding of the running back position. It is much more than the threat of being able to break off long exciting plays... (which they were both able to do) It is also about having a team lean on you, when everyone knows that you are going to run the ball, and carrying your team through.... it's about catching.... BLOCKING. Emmitt was leaps and bounds above Sanders at protecting his Quarterback.
So....
Emmitt has more yards.
More touchdowns.
More wins.
Better blocker.
3 Super Bowl rings.
The All time Rushing Record
ect....
I will give it to you though... Barry does have the whole "More runs for a loss of yards" thing going for him. Which is great considering how many less times he even carried the ball.... and the fact that Emmitt was still playing much further into his downslope.
Emmitt Smith could throw his team on his shoulders, and carry them through any tough game. Barry Sanders might break you off a long run in a game... but he would get stuffed much more than the average back, and also cause a lot of three and outs for his team, but not simply getting a few yards on a play. Gaining 3-4 yards on a play isn't exacty a bad thing all of the time, when your team needs it.
Also... don't come out with the nonsense about Barry being on a horrible team, because Detroit had a high powered offense. Two of the leading receivers in the league, one of the leading QB's in the league as well. Detroit always had an awful defense, and that was their problem. It is a flat out MYTH that Barry was stuck in a horrible offense, and that he could have been so much greater with a better line. That line protected their QB enough to have amazing stats... as well as the WR's and Barry himself.
Don't get me wrong, Barry Sanders was an AMAZING running back. The main difference that I see, is what many people have said. Barry Sanders had GREAT moves, he shook people out of their shoes, and did things looked impossible. Emmitt Smith was a master at making subtle moves, cuts, drop his shoulder at a certain angle, ect... and almost looked like he was doing nothing. He was so great, that he made it look easy. Which is why a lot of people don't give him his credit... he made things look too easy.
