This all the way. It's funny, even before Marshall Faulk got up there in terms of "best RB talk", he pretty much introduced me to the game. I was too young for Sanders and those before him, but Faulk was pretty exciting. Over time, after watching film and learning about these guys, I'd definitely rank Dickerson, Sanders, Payton, Brown & OJ in the top 5. But in a top 10 I'd definitely have Faulk & Peterson, and even still, at some point between 6 and 9, Emmitt Smith. I don't think you can disregard the numbers Smith has put up in his career.
Between Barry & Rice, it'd be nice to see them both on the cover, personally. But if I had to pick one, it's a tough choich, but I'm going with Jerry Rice.
