You have it backwards. Ali was an iconic social figure. People loved Ali. When Frazier knocked him down, many considered that to be a tragedy. People disliked Iron Mike.
Ali - Activist, culturally aware, handsome, articulate, leader, a representative of a race.
Tyson - Brutish, ignorant, unattractive, lisp, inarticulate, goon, "dirty fighter," ear biter, rapist, convicted felon.
In your wildest imagination you can't imagine that those non-boxing traits influence how their fighting careers are judged?
Ali would not have "danced" and "jabbed" at all, if he fought Tyson in his prime. Not one fighter was able to "dance" and "jab" Tyson in his prime. Ali would have tried the dance and jab crap and Tyson would have been up in his grill, in his unique manner, instantly, and Ali would have been just as overwhelmed as everybody else who had Tyson run them over in the ring.
Foreman maintains that he was given spiked water before the fight with Ali and wasn't at his best. Also, Tyson was a quicker and more accurate puncher than Foreman - one of the reasons he was so devastating.
Larry Holmes was KOed exactly one time in his career - it was Tyson.
Also, I went back and watched some Ali fights - he was knocked on his @ss by some British journeyman when he was 21 years old, and he needed his corner to cheat for him (smelling salts and delay through ripped glove) to survive into the next round. Overrated.
Anyway. Fun to hypothesize.
