the sad thing about tyson is he had no one to fight that was truly world class.
if you look back to the 70's the calibre of the top heavyweights was far higher, which is why so many great fight took place, ali,foreman,frazier,norton,lyle,shavers,holmes,bugner and even the like of ellis and bonavena were better than the most of the top guys in the 80's and 90's.
for all his speed and aggression tyson was still unable to stop james smith and tony tucker two box fighters who were good but not in the league of the guys i mentioned before. he was exciting in a very poor era and what the sport needed at the time, people that rate him as the best heavyweight got caught up in the excitement of him knocking out poor fighters and believed the hype, he is in the top ten but not near the top imo.
