BULL. The top ranked big men of yesteryear in Willard, Baer, and Simon took a good punch. Before that time it was Jeffries. If size does not equate to either having ko power or the ability to take a punch then why not eliminate the weight classes?
I would not call Chuvalo small. He was a very compact man with a large head and thick neck. Two assets while taking a punch, combined with overall weight. It was the same thing with Holyfield, so perhaps neck size/strength and head weight is part of the equation too, and generally speaking the bigger you are the larger your head and neck are. Thanks, this was not an easy post to put together, but if you look at the data objectively I think there is a correlation
If size meant durability was a given it would not preclude lower ranked men from having good chins ,but the fact is many giants had decidedly average whiskers. Jose Santa,Ray Impelletiere,Victorio Campolo,Primo Carnera to name a few.One was champion and two were world ranked . Lower rankers who did not possess top mandibles include Mike White,Jack O Halloran,Sammy Scaff. Not only were they less than iron chinned they were not big punchers either.Perry is correct.
There is obviously a direct correlation (with obvious variations on an individual level). Just as obviously this correlation is subject to diminishing marginal returns. It could start at 190 pounds; it could start at 230. I don't know and I don't think we can know. US citizens will get what I mean when I explain the marginal utility of a chin. In the Nfl height is a prized attribute for quarterbacks. Given the choice between two otherwise identical quarterbacks one of whom is 6' (182 cm) and one of whom is 6'3" (190 cm) the taller one will be preferred and will probably be more successful. But at some point this breaks down. There are no very successful very tall (6'7"/200 cm+) quarterbacks because the utility from height is not infinite. Primo Carnera and Michael Grant do not have better chins than George Chuvalo and David Tua. At some point excess size is just excess.
90% of durability is down to anticipation and positioning. The last 10% probably represents how naturally robust a guy actually is and that is only called into question when being blindsided. Pro boxers rarely get blindsided when equally matched. Size? It's not so much that a fat guy has a iron jaw. That is so ludicrous. A bigger man can "take away" a smaller guys power through controlling ring centre, taking the front foot. Hard to knock a man out while you are backing up. So it gives the impression that a guy takes a better shot if he's the one going forward because he's leaning all over a smaller guy who has lost all his leverage and is sapped and drained of his full potentia with such a big guy barring down on him. The big guy is not getting hit with the guys best power shots. So chins and size, is there correlation? Physically No.
Yea he actually did. and if you look at all k.o statistics they all go down with the more heavier opponents,and in different weight classes a k.o artist may not be a k.o artist at a higher weight,this is shown almost always ..Pacman as example,he was not the monster puncher he was at a lighter weight because he fought BIGGER guys. this isnt that hard to ssee it really isnt. WEIGHT is a huge factor in the overall angle of how a fight is fought because then power to the who relies on it more when not as effective changes the dynamics of the fight itself. Its simply HARDER to get a k.o on a heavier guy on AVERAGE.
I'll tell you what is probably at least as important, if not more so, than size, when determining punch resistance: Conditioning. Guys who have top shelf conditioning seem to take punches better and also definitely seem to recover faster from punishment. But the most important question of all is: is the guy Samoan? They seem to be born with granite chins
To be fair he didn't really fight very many elite opponents. Also the fact that people had to work uphill to reach his chin might have helped.
Conditioning is a factor. The better conditioned a fighter is the harder it is for him to become so fatigued. He can continually react in time to what is coming his way. His ability to maintain distance remains sharp. He can prevent his brain rattle when he is hit since he retains strength enough to roll with the blows. Once fatigued a fighter finds it tougher to react in time to the blows coming his way. Harder to keep out of the way as he struggles to maintain safe distance. The more tired you get the more shots you get hit with. It's as simple as that. They get so tired they begin to brace themselves as a blow lands rather than roll with a blow. So the conditioned fighter gives the appearance of taking a better punch than the fatigued fighter. So yes. A well conditioned fighter can give the appearance of taking a better punch because a conditioned fighter remains alert enough to anticipate more.
Nice post. I haven't gone into it but always assumed that it had something to do with improved vascularity. Your post also makes sense. I also reckon that strong neck muscles and / or a big head help reduce torque forces causing the brain to bounce against the skull. That's conjecture, I hasten to add
