Your example is ridicolous. Foreman beat Frazier but Ali (who wasn't in prime) destroyed the prime Foreman.These type examples don't work. Savarese or Stewart used Foreman like a punchin'bag. The old George wasn't impressive . Axel? Foreman wasn't good at all. Tyson quit against McBride.McBride did nothing special. This Axel/McBride example don't work.
The Axel/McBride example works perfectly. If McBride could kick Tysons ass, I bet a 65 year old Foreman could have stepped in there at that point in time and done the same thing. At that point all of Tysons heart and stamina were in the toilet and he would have been easy pickens for tons of heavyweights. Also, a 41 year old comeback Foreman was a totally different animal compared to the 48 year old version we saw that still had enough to (in reality) beat Shannon Briggs....which was totally amazing for his age.
You see in Tysons face when they mention Foreman, that the fight would've been troublesome, even against the old George.
