Here is my top 3...
I don't know everything there is to know about football, but I am a big fan and these are the three that I came up with. I'm curious to hear your feedback and who you think are the top 3 runningbacks of all time.
LaDainian Tomlinson is the man, but I'm not going to put him in my top 3 yet...definitely my top 10 though.
1) Jim Brown
2) Walter Payton
3) Emmitt Smith/Barry Sanders (if Barry had a line like Emmitt he probably would've won a few titles too, but since Emmitt did make things happen just the same you can't put one above the other)
