Of the top 12 running backs in NFL history, 6 were instrumental in helping their teams win Super Bowls; 2 more played in Super Bowls; only 4 never played in a Super Bowl.
Of the top 12 pass rushers in NFL history, only 5 were instrumental in leading their teams to Super Bowl wins; 3 more played in Super Bowls, and 4 never played in a Super Bowl.
Of the top 12 running backs, 10 were 1st round picks. Of those 10, only Emmitt Smith was not a top 10 pick. 2 others were 3rd round picks, both of whom reached the Super Bowl, but didn’t win.
Saying that top running backs are not important to winning Super Bowls makes about as much sense as saying you shouldn’t spend a 1st round pick on a pass rusher. It is completely ahistorical nonsense.
