He was the best runningback that I have ever seen or probably, will ever see in my lifetime. He had an extra gear that I have only seen in Deion Sanders. But Sanders was a defensive back. As far as Emmit Smith is concerned, it was two different styles of runningback. Emmit was a slasher, with no break-away speed. Emmitt could not hold Bo's jock. They should not be in the same conversation. Herschel was the closest, but he was not nearly as fast as Bo. Herschel also topped out at fourth gear. Bo had fifth gear.
