Bo Jackson
Guy was a monster, would have been a top 3 greatest ever if he didn't break his hip.
I have to agree here. In terms of the BEST running back, Bo took the cake. In terms of best career as a running back, Sanders, Payton, Brown, Smith, Sayers in that order.
Here is a little idea why Bo was the best:
He was 2nd string most of his career behind Marcus Allen
He finished with an
average of 5.4-5.5 yards per carry.
When he did the combine for the draft (or the similar version) he was listed at 6'1" 225-230# and ran a 4.12 40. (

He was a baseball player...football was a hobby, a side sport to him.
He was able to hit the scoreboard in the Superdome with a football he threw. (No one had ever done it till then).
He amassed 220+ yards in a MNF game against Seattle (The Bosworth play)
His first 5 rushes in the NFL were 40+ yards (IIRC).
Oh, and he was just a freak of nature as well. I could see him having 20k yards if he could have played his entire career.
I guess I could just say he was one of the best Athletes ever. (Best thing I remember about Bo is him breaking bats over his knee when he struck out.)
And here's a college run: Roughly 71 yards in 7-8 seconds.
