This really hits a nerve with me, because if you watch the Tyson fights from the 80s, he could have been the best fighter of all time. There has never been a better match of speed and power...ever. Tyson made a series of bad choices when his mentor died, and dropped his trainer for no real good reason, and signed on with Don King. He then became a headhunter, looking for one punch to KO someone, rather than working the body and throwing combos like he did when he was 19 and 20 years old. In his prime, Tyson would have murdered Kimbo, literally. Kimbo is slow and telegraphs punches...Tyson was much quicker in his day...no doubt however that Kimbo would win now...for christs sake Tyson lost his last fight against Danny Williams...
