Does going up in weight improve your chin?

[Interloper]

It actually can improve your chin in two ways (one being the weight thing mentioned above).

Secondly, fighters in higher weight classes tend to be less explosive and slower than those in lower weight classes. You're less likely to get clipped with a shot you don't see as the punches slow down. Guys hit harder, sure, but not with the same dynamism of the lower weights. This alone can give the illusion of your chin improving, when it actually doesn't. Perceived improvement is still improvement though, especially in boxing.

It's an interesting question, and I think some good possible answers have been given. I'm going to speculate that, in addition to what's already been said, a fighter's higher body mass allows more absorption of force to the head. I believe that a fighter's chin does improve as he goes up in weight. The trouble is that there are generally harder punchers at the higher weights.

It depends, if a fighter moves up in weight, it can strengthen his legs and his neck, two things needed for a good "chin". Anybody who gets hit flush on the jaw/chin area by a big hitter is going down, how he recovers from that punch, can he get back up? can he stay on his feet without looking funny? That all comes down to fitness, strength of the fighters legs and neck and natural God given physique.

Guys like Hagler, Ali and prime Leonard could take HUGE shots and not even look like going down or go down flash but be back up. Khan in his recent fight was taking average shots and looked troubled every time, with him I do think it's a weight issue and who ever is conditioning him needs to work on his legs and neck area.

Will there be taxi drivers at the weight Khans chooses... if the answer is yes then he'll still be doing the "stanky leg"

if you are draining yourself to make weight absolutely. look at cotto moving up from 140 to 147.

i dont think thats the issue with khans chin though, as far as i know he doesnr kill himself to make 140 anyways. just a case of an average chin and really poor defense.
