Arm wrestling isn't a good indication of strength, its more technique and doesn't use much of the bodies muscles
As for the match up I like Frazier's speed and Marciano's underrated defense and timing. Allot would boil down to how each handle the other man's power. Frazier was blown out by Foreman, how would he handle Frazier's power? If Marciano was decked by Moore/Walcott how would he handle Frazier's relentless assaults? Anything could happen in this 1
I think the Marciano from the Walcott fights vs Frazier from FOTC would be a pretty good fight truthfully. A real battle of wills.
I can honestly say that I would bet my house that the Walcott of the first Marciano fight would have beaten Quary, Chuvalo, Bonavena. I think that a faded Charles would have done also. I even think that a 37 year old Louis could have taken them outside of Quary.
It's not about if these guys would beat these guys, that's a different topic, it's about who was more durable and tougher to stop.
Don't you think Frazier would get to old Louis, Charles and Walcott? Do you think Marciano would easily knock down and knock out George Chuvalo and Jerry Quarry? People have been arguing that Frazier doesn't have true KO power because he couldn't KO any of them "clean", he "only" won by TKO (after injuring both of them badly to the point they could not continue).
Not sure on Walcott and Charles, these guys were defenses genuis. Frazier would in deed have trouble landed his best on them imo. Old Louis is other story.
Well, then you might lose your house. Walcott had 10-9 record in his last 19 bouts, don't you think he was past him prime. Charles was also past his prime and Louis was a shot fighter. He only had 3 KO's in his last 9 bouts before he fought Rocky.
Both fighters would be on the inside, throwing bombs. I can't see Frazier recovering from one of those bombs which almost decapitated Walcott. Down goes Fraziah! Down goes Fraziah!
I'm not sure I would have those versions of Walcott and Charles beating prime Quarry or Bonavena. Close fights as far as I'm concerned. Prime for prime, yes. Or what about Ellis?
