yeah a head aint made to take blunt trama. aint no1 born with a natural ability to take punishment to the head that just makes no sence. now theres people who just have more heart and determination than others yes. andre berto and juan urango physically built the same. juan urango aint born any different then berto actually juan urango is prolly flatfooted. but anyway berto is more mobile and less likely to take hits than urango. because urango is slow he knows hes gonna get hit. he has to take one to give one. which helps him resist punishment. if berto was to lose his mobility he would be getting hit alot more and berto is not used to that which would make him likely to get KOED. or berto would realize that his mobility is gone and would anticipate getting hit more just like urango does. but because berto is mobile and fights with volume and more intensity he worries less about getting hit like urango.
It's almost impossible to predict how much a fighter can improve his punch resistance. For example, take Khan's KO from Prescott. Ever since that loss, if Khan constantly took a load of heavy shots and got accustomed to taking shots to the head to a certain degree then I personally think his punch resistance is likely to improve (not saying granite, but merely 'improve') and thats only by high quality sparring. Other factors such as improving leg strength and fighting at a more comfortable weight can only positively add to the theory. Saying - 'oh his chin has been and always will be glass' are just baseless assumptions (unless somebody could put down some facts).
How about him being floored in the amateurs? If that's not enough, how about the feather-fisted Willie Limond? Or the not-so big puncher Gomez? And then of course we have Prescott, the first decent puncher, who not only rocks him with a jab, but sends him to the canvas with the first power shots he throws. So I'd change the above to: "Saying - 'oh his chin has been improved since moving up' are just baseless assumptions (unless somebody could put down some facts)."
We are talking about chins. Look if you do not think fighters like Cobb, Chuvalo, Ali, Langford, Lamotta, Hagler and plenty others were born with chins then so be it. I'm not going to bother debating what has been an established pugilistic fact since it's Greek origins.
ok Ali is a perfect example im glad you got that name in there. when ali was younger and in the amatures. he has gotten knocked down a few times. now because he was fast as hell he definetly didnt worry about taking hits. so whenever he got hit flushed he went down (he still got right back up and won). the older and older he got he lost his mobility and and he began taking more hits. the same hits that would have had him kissing canvas when he was 10-15 years younger. because he lost his mobility he began to anticipate getting hit more and he became more punch resistant.
By Khan being floored in the amatuers and the rest of his chinny moments just show that he had(has) a weak chin but we all already know that, what is your point? My point is aimed at whether a fighter is able to improve his chin over the length of his career. By me using using Amir Khan, is just an example.
My point is.....when observing Khan's career so far and reviewing his knocked-down/out moments, the notion of him having a 'glass-jaw' is not unfounded. The question of whether Khan's chin has improved, has not been answered. We've yet to see any evidence that this is true.
I was questioning people saying Khan 'will ALWAYS have a glass jaw'. I agree Khan chin has not really been tested since the Prescott loss. But again, that wasn't my point but we will have to wait and see to the sort of punches Khan takes and whether their is any improvement.
Weak punch resistence can be improved, less draining, more muscles on the legs and other areas, better punch estimation and defensive techniques like head movement, plus experience, but it's unlikely that fighters showing a weak chin in several fights will be able to take flush bombs from big punchers. They can't allow that to happen therefor their job is to develop their skills to the level they don't get hit with those kind of bombs and hope their punch resistence improved to the point if they do get rocked by the average power shot that gets through even to the best defensive fighter every now and then, they keep composed not to offer the opening for the finishing bomb. Surviving skills are just that: skills. IMO that's the big question mark around Amir. He can't take Maidana's best shot, but if a smaller power punch gets through and rocks Khan, will he able to keep the hands up / grab / fight back on instinct effectively enough not to get caught by the biggie? We'll see.
