I have watched both of these guys and noticed that they have the exact same style. But the difference is Tyson is faster, stronger, and has better defense. It's like comparing Rampage to Forrest, Rampage is better at everything. The ONLY thing Frazier has on Tyson is heart. So I think if we want to indicate how Tyson would do against the golden age HW's, we look at how Frazier did, but Tyson is like Frazier 2.0. I seriously think Tyson would be the worse possible match up for ALI, in the history of HW's. I think he would beat Frazier via 2.0. But I think he would have a shit load of trouble with Foreman. That might be a fight he loses. And this is all of them in there primes.
