As much i watch Tyson as much i see that all his good fights are against "boxer" type boxers, which are making one and the same mistake...

Comparison between Frazier and Tyson is only possible about the size and shape, but in style there is absolutly nothing to compare. Frazier was classical swarmer, where Tyson tried to counter on streight punches and then clinch... For me here start all problems from Tyson. Formen didn't have streight punches and where Tyson loops all of his hooks Foreman will aways connect first because his are compact! Both of them have problems with boxers who can stand their ground and here againt Foreman is in advantage. I am sure that Foreman can make Tyson go backwards or he will just rest on him in the clinches...
