Nobody has an iron chin. you either see a punch coming or you dont. a knockout punch is a knockout punch. If a knockout punch lands just right you are out. even if it lands on marciano or ali's chin they get knocked out. it is a fact both marciano and ali avoided geting put to sleep in the pro ring-and both faced chilling knockout experts. yes both got hit by good shots but not by knockout blows. granted the good shots they took may have knocked out other fighters but the best fighters levels of antisipation are much higher tuned. having the where with all to brace yourself before the moment of impact can be the difference between geting a concusion or not geting a concusion. some fighters are more resiliant but basicly having an "iron chin" is more a case of having beter anticipation. george foreman could hit a bag harder than archie moore could but since both could get the job done in the ring without using their entire maximum acheived force what does it mater? ali having a beter chin because he absorbed a george foreman right hand that he was timed and ready for does not outrank a joe walcott left hook that marciano was also ready for.
An interesting question would be that if Marciano and Ali fought, who would more likely be knocked down. It always felt to me like if they fought, Ali would stop Marciano on cuts. However, my view is that it is more likely Ali would hit the deck sometime during that fight. They both took a great shot but Marciano was the harder puncher of the two.
Louis was an out of shape 223lb, and looked like he wasn't even trying vs Layne..I hardly saw a moment in that fight where he threw a real punch. Louis did knock out Rex Layne in one of the exhibition matches. I just think Louis was better in all aspects than Layne. Better Jab, much better skills, bigger and taller, bigger puncher. Layne had youthness on his side, had top stamina, a good beard, a nice right hand, and looked great against Walcott in 1950...but I just can't see anyone besides Rocky Marciano, and possibly Clarence Henry walking into Joe Louis in 1951 and coming out alive.
The Cockell reference was said in jest. Ali`s chin was even better than Clays. As he matured, and slowed on his feet a bit. He was reachable, but his chin as Ali was granite. As for now one having an iron chin : see Lamotta,Jake...
obviously lamotta was very resiliant, had a bigger head, short neck but above all he realy rode shots well and knew what was coming. he rolled with a blow. blindfolded with his hands tied maybe willie pep would knock jake out. do you realy think he had that much harder bones and tolerance? we are all human.
ali was more proven. easy but still the marciano fanatics argue for their man. foreman or shavers might destroy him if they landed. ali proved he could take it from the reknowned big hitters. not saying marciano couldn't but ali is easily more proven against the really big punchers, liston, foreman, shavers v moore, walcott, charles, old louis, no contest.
I am a fan of both guys, please dont acuse me of being biased of marciano. ali acheived a whole lot more than marciano and yes his longevity counts. however ali not marciano was knocked out by kent green albeit it as a youngster. if ali (or anyone for that mater) had an iron chin did he grow one later on? like i said before you either see it coming or you dont. I still say both score 10 out of 10 for durability.
You're referring to a bout when Ali was a 17 year old amateur to make a point ? A little bit of a reach, isn't it ? The argument for Ali's chin is not one of longevity but of the punchers he faced : Liston, Williams, Frazier, Norton, Foreman, Shavers ... Marciano's may have been just as great but it is no where near as proven ...
Both had top level chins, Ali could roll with the punches well and Marciano's defense is underrated. Ali beat a lot of Big punchers like Foreman and Liston and he recovered from being seriously injured by Frazier in fight one in the 11th and 15th. Ali was also dumped hard by Cooper and was shaken. I think in the Foreman, Liston fights it was a matter of Alis speed and ability to roll Marciano was dumped by pin-point punchers like Walcott and Moore but bounced up quick and unshaken in both fights Its hard to evaluate a chin but I can only say they both had solid whiskers
the point im making is you cant grow a iron chin, you either learn to see a punch coming or you dont. if there was such a thing as an iron chin you would be born with it. the kent green episode is an example of ali overcoming suseptability to a ko blow.
The first round of Walcott one shows Marciano had a terrific chin ... Walcott jolted him .. Walcott was fresh. Walcott could hit and was all over him ... Rocky instead of crumbling came roaring back ... case closed on that one ..
