Assuming you are talking the 1972 Foreman training for the Frazier bout, then I see Foreman bouncing Tyson off the canvass multiple times ending in a TKO, just like Cus D'amato had warned Mike about.
Great Fight! I don“t know, for me Prime Big George is the only one who can beat Prime Tyson. But I think speed kills so I go with Tyson by KO inside 5-6 Rounds.
Foreman was stronger but more crude. Tyson a lot smaller but more polished. I think Foreman would have to land only a couple of big ones to have Tyson in trouble, whereas to get Foreman out of there Tyson would have to land more. That said, Tyson would land better and be harder to hit. I think it would be an awesome match, actually. I can't really pick a winner right now.
I find it laughable how people think of Foreman as some indestructible juggernaut. The man was wide open and fought with his chin in the air. If Lyle could rock his world then so can a prime Mike. 50/50 fight. Foreman is bigger, stronger and has a stylistic advantage. Tyson is faster and way more polished.
Tyson because at their best he was faster, smarter better chin more heart and the better puncher and all round technician.
Foreman by KO in 3 rounds or less. Foreman is bigger, has a much better chin, is stronger, hits harder and is much meaner.
What? You've seen the strategy Ali used, correct? Tyson isn't doing that. Ali outsmarted Foreman and tired him out. Different situation altogether.
