Bo Jackson ... I'd say the best NFL running back of all time. Had he not been injured, he would have put up some prolific numbers. Only RB in history to have two TD runs of 90 or more yards. Mixture of speed and strength. Add to that his baseball career ... man, what an athlete. Also, was the best video game running back of all time ... in the Techmo Bowl game on the first Playstation.
Bo Jackson July 11, 1990: Bo ran up the outfield wall. Literally. He chased down a fly ball and caught it about four steps in front of the fence. To avoid hitting the wall, he put his right foot on the wall, then his left, then his right — until he was 7 feet off the ground and sideways. For a guy who didn't want to be seen as a superhero, he sure kept doing superhero things.
