I favor 60s Ali due to his great speed combined with condition + physical advantages. I think I still favor early 70s Ali as well, but not after 75 (I'm not sure about 73 to 75). It's easy to favor Ali when you consider his physical advantages, plus Rocky's susceptibility to cuts. Then you think of the shorter, older Walcott (who was in great shape though), who gave Rocky all he could handle in their first fight, or Charles I. On paper, it's not hard to make Ali the clear favorite. But overall, I think it's not as clear-cut as some people may think. You also never really know with Ali... issues with Jones and Cooper (yeah, I know he was young), but then defeated the seemingly invincible Sonny Liston. 70s Ali beat Foreman but lost to Norton. Bonavena, who in my opinion didn't have the raw power as a peak Marciano, still gave Ali a pretty tough fight until Ali landed his left hook. He didn't knock out 6'0" Rudi Lubbers in 73, and he didn't stop the Bayonne Bleeder—Chuck Wepner on cuts. I don't want to make Ali seem worse than he is. He was one of the greatest boxers ever. I just mean, you can never know for sure without a real fight. Every boxer is different, every fight is different, and styles match up differently. Rocky came from a smaller generation, but comparing those 2 ATGs is a whole different thing than matching up Ali with fighters like Lubbers, Weppner or London or whoever. I think it's way more unpredictable. And why should Rocky be an easier opponent than Norton, Young, Shavers or Spinks? Rocky was always in top shape (unlike Ali in the 70s). He was as determined as one could be, tough as nails, and not the best heavyweight of his era for no reason. And last but not least, Ali had great respect for Marciano. This content is protected
There are very few versions of Ali I give Rocky much of a chance of beating. Marciano is a legit ATG but does poorly in H2H match ups, mainly due to his size. Over the course of the fight, Marciano would take much more damage than Ali - who would find Rocky hard to miss. And if Ali needs a rest and rope-a-dopes for a round or two, are we saying Marciano hits harder than Foreman? Because Big George launched bomb after bomb at a stationary Ali and couldn't make a dent. If Ali is stationary for most/all of the fight then Marciano has a decent chance but I can't see Muhammad doing that. He'll sticking and moving for chunks of it, spamming that right cross and tying up and leaning all over the smaller Rocky. Marciano has his moments but can't land consistently enough.
