I like Chisora is this match-up. Hear me out. Vitali and Wlad were able to neutralise Frazier/Chisora's style, but Ali was unable to. Ali didn't have the best inside game and struggled to keep Frazier at bay. Chisora is an updated version of Frazier, but bigger and more powerful. Ali struggled to take Frazier's punches, so I can't see how he would deal with Chisora'. Ali would beat an out of shape version of Chisora, but I think the Chisora who fought Vitali would be too much for Ali.
1964-1967 Ali could have, size does not mean a single thing if you cannot catch what you are trying to hit, and back then Ali could dance non stop, for 15 rounds without missing a beat. As I have said in the past threads, Ali had accuracy confidence, footwork, catlike reflexes speed, and stamina. The 1970-1978 edition, Chisora would defeat him, all those above mentioned qualities gone.
I can no longer hear you out. You have lost any semblance of credibility. But, perhaps you have just been trolling from the start.
