Nothing against Lewis but speed kills and he didn't have enough for Ali, Ali gets a wide UD 9 to 3 IMO. Now Tyson, Holy, and Holmes would be very tough fights for Ali IMO.
So I guess the question the thread should ask is who wins these possible matchups between the following and by what outcome?: Prime Ali vs. Prime Tyson? Prime Ali vs. Prime Holyfield? Prime Ali vs. Prime Holmes?
In a 12 rounder he'd win around 4, maybe 5. Ali wasn't invincible, and against the long jab, power, skills of Lewis he would struggle.
60s ali is one of the only fighters id favor over " prime, motivated" :yep lennox. i think it would be more competitive than most think but ali's hand and foot speed, ring generalship along with his chin would earn him a 3-5 points victory.
