He might not be considered the Greatest of all Time — that title surely goes to Muhammad Ali — but there was perhaps no boxer in history as feared as Mike Tyson. Winner of 50 out of his 58 bouts with 44 coming via K.O., anyone who stepped in the ring with him knew they had a chance of hitting the canvas in the first round.
