a real good running game is a lost art in the NFL its all about passing now... the people that are being named in this list are from when i was young or in some cases before i was born i never saw O.J play i never saw gayle sayers or Tony Dorsett i did see Barry sanders and Emmitt Smith I do put emmitt in this convo even tho yes he did have one of the best O lines and arguably the best blocking fullback ever he still deserves to be in this convo.
