First of all I always thought Tyson was overrated. He had the head movement and busy for the first two or three rounds After that he would slow to a snails pace. Against Tucker Tyson threw 412 punches. Bowe threw 711 punches vs Holyfield. That's almost 300 more. Plus Tyson would always look to clinch rather than fight his way out. If Tyson is being out worked then he is beatable. Let's remember that it was Holyfield who loss 2 out his last 4 fights one by KO before the Tyson fight. Yet you could tell early that Holyfield came to fight. Watch the video Tyson is the one who wants to clinch. I think Ali and Marciano were great. Not because they were unbeatable. It's the fact you would have to kill them in order to win. Tyson like most bullies lack the heart of a Champion.
