I love the rock for what he was and what he means for boxing but honestly big george is too strong on the inside for rocky to handle he couldn't stop george.
Marciano had great chin, Frazier had good one. Frazie rliked to keep hi shead in opponents chest of stomach area, Maciano didn't. Foreman shoved Frazier to get room for that first big shot, and Frazier was right where Foreman wanted him for it. I know Frazier underestimated Foreman
You know, Foreman was not that hard to hit, a lot of people think Marciano needs to get through early rounds safe--well, who doesn't? But Foreman needs to too, and in what would be a brawl probably, the cooler Marciano may take him out early. Of course it could go other way, but overall I see Marciano as better of two. That's head-to-head or overall.
REmember Ron Lyle who was a good puncher but not a Marciano puncher at all had Foreman down and badly hurt, look at Lyles record, he did not KO a lot of guys that were already KO;d but he almost had Big George, so its true you can look at the Frazier fight (different style than Rocky) and say this is what would have happened but reverse the logic and picture Marciano landing his big shots on a hittable Foreman and Big George getting hurt early,Marciano had better will to win than Lyle. Also Foreman may have hit harder than Walcott but Jersey Joe was a pinpoint power puncher with great timing and he could drop you hard with one punch from either hand but he was also a slick sharpshooter with great legs and upper body movement
Blind Freddy can see this particular matchup is a very very tough one stylistically for Marciano. As D'Amato said, no swarmer in history beats Foreman.
No chance Marciano escapes the third round. Marciano was dropped by sharp punches in Walcott and Moore- George is a heavy puncher- The rock was made to order for George's uppercuts and hooks. Marciano could be hurt and Foreman would do it. The Peralta fight that was mentioned was a very young Foreman. We're talking the destroyer of Frazier and Norton, right? Marciano's power wouldn't get far here; Foreman would shove him back into hook and uppercut range and destroy him. Foreman would make this look easy.
First, Moore didn't "hurt" Marciano. Did Foreman hit harder than Walcott? Ali "destroyed" Foreman, but not Frazier and Norton, right? Nobody, and I mean nobody, makes things look "easy" when they are facing Marciano... that certainly includes George.
Before one just sort of lumps Marciano and Frazier together and then figures that Foreman-Marciano will be a carbon copy of Foreman-Frazier, I do think it's important to remember that Frazier was past his prime and 10 pounds overweight when he fought Foreman, and that Frazier didn't have quite as sturdy a set of whiskers*(you don't have to agree, but I think so and the consensus of fans does, and I think the evidence points that way) as Rocky did or as much explosive and two-handed power. I also think Frazier was a slower starter than Marciano, and his bobbing-and-weaving, cross-armed defense, while very effective against straight punchers and jabbers, wasn't really the best for dealing with a largely underhanded, sweeping, hooking puncher like Foreman- in fact, it almost left him open to and caused him to move into Foreman's types of punches. I think Marciano would be considerably tougher for Foreman than a declining Frazier was. However, I will still go with the bigger, stronger man who loved guys who came at him to take the win. Foreman by TKO 4.
Walcott was winning handily when he got caught, and others displayed he could be ouboxed, even though they were'nt the best boxers, so against better opposition I imagine he could be outpunched or outboxed. He may not have been "hurt" against Walcott or Moore, but Foreman hit much harder and would have hit him much more based on Marciano's style and Foreman's punching angles. The hooks and uppercuts would easily find their target.
