Do you think having a granite chin is genetic?

McCullough and Margarito both had small traps, and neither had thick heads. Margarito had an especially elongated, thin skill, but could take all kinds of punishment. Rios as pointed out, very thin neck, average size head at best, all three guys granite chinned.

Chuvalo may have the best chin of all time, so good call. Dude fought all kinds of amazing punchers, and never tasted canvas. Vitali and McCall top out the top three heavyweight chins in my opinion.

I think Margarito is a 10 chin, 9 minimum. 95% (atleast) of guys would have been KTFO in Cotto 1, and Pacquaio matches Margarito was involved in. Yes, he was KO'ed in the Mosely fight, but he had just been caught cheating, and I think his will was completely broken. Even with that fact, he took incredible shots from a VERY hard puncher who was literally almost knocking his block off for 8 rounds straight. Mosely was literally sitting down on nearly every power punch and slamming his head back 3 to 4 times in a row consistently. Most guys would have lasted MAYBE 2-3 rounds of taking that abuse, he showed an incredible chin even getting knocked out.

Logically I'd think so too, but I don't see any consistencies in the criteria. There are granite chinned fighters with large necks and small necks, thick skulls and thin skulls, large legs, small legs etc etc.

 

Right, obviously not getting hit is the best scenario, but when talking chins, we are talking about the ability to absorb punishment. We are discussing when these guys do get hit, what makes some be able to eat bombs all night, while others go lights out from one or two decent shots?

Speaking of which, Hopkins has shown to have a great chin. Rarely is caught, but when he is, seems to have a VERY solid chin.

 

In that case, having a smaller brain would be very beneficial :yep

The dehydration thing is without a doubt though, I've heard your cerebral fluid is among the slowest to rehydrate when you're drained and trying to put back on the weight, but I don't know for a fact if that's true, although it makes sense. Makes you wonder how many less fighters would wind up with brain damage if people had to fight in their natural weight classes? Meaning weigh in an hour before the fight or so, so fighters had to be at the weights they naturally belonged, and weren't dehydrated.

 

Go watch glass chins like Terry Norris and your boy Amir Khan especially against Prescott, then watch iron chinned guys like Evander Holyfield eat shots from guys 30-50 lbs heavier all night, or Margarito vs Cotto 1. You're going to tell me some guys aren't born with the ability to take significantly harder shots than others? That's garbage, plain and simple.
