Tyson would get tagged hard, I just don't see him not getting hit. He did nothing but try to knock his opponents out. He did not move his back as much and he rarely jabbed. No doubt does Foreman win by KOI feel Tyson could get a decision over Foreman in 1991 granted he doesn't get tagged hard early. But prime vs prime Foreman steam rolls over Tyson in the same manner he did Frazier, just Tyson doesn't get up 6 times, he gets up maybe twice.
plus Tyson did not have the mental stability to do well over a 15 round fight, alot of his trainers said that Tyson got really impatient after round 6.Big man that stood up to Tyson were the ones that found more sucess against him.
Foreman wouldnt back up, and Tyson wasnt really a guy that would try to box in a fight. Foreman by late stoppage likely.
