Mike Tyson doesn't make some list makers top heavy weights of all time list. When Tyson does make the list it's because he popularized boxing in the time he was active. He is much like the Klitchko bothers are today, dominate, but not "great". Tyson would probably have been crippled by Ali, Fraser and 8-9 other guys who stood out as great heavy weights in their time. You want to see greatness look at http://www.youtube.com/watch?v=C84ZxM1txLA
That being said, Tyson was an terrible force to be reckoned with in his day, but as far are skill goes couldn't be compared to Mayweather or Pacio today.
