There is no such thing as a 'glass jaw' or a 'weak chin'

If Khan has such an dog awful glass china chin, he doesnt need a heavy handed KO artist to knock him out. Fail.

 

There are fighter's with weak chins whether's It's genetics or not I doubt anyone really knows all I know is the Chin is one of two places the other I believe being your balls that it is impossible to build muscle on It's one of the reasons fighters get knocked out when they get hit there the others are of course the impact of the punch and the speed that It's delivered i've also heard people say the snapping motion of head after a punch, ive also heard building neck muscles like Holyfield can lessen that. So why some fighter's have a great beard and other don't is unclear I've thought about it a lot whether it's there will maybe just there mentality then I think but Foreman KO'd Frazier the perfect example of Will and having the mentality of a fighter. So to me at least It's a great unknown but there are fighters with great punch resistance and those with little.
