Definition of a Glass Jaw...

If those guys took 100 power punches from a comparable puncher to Mosely p4p, that were not even partially blocked, slipped or rolled theyde get knocked out too. Margo has no defense, alas.

 

If Mack had given his all to finish Andrade after he knocked him down, he'd probably have KOed him. However, he decided (wrongly) to box again, letting Andrade off the hook.

 

Mosley (an old Mosley) shattered the myth of Margarito's Iron Chin. Literally.

Cotto had no problem taking Mosley's punches.

 

Cotto didn't take nearly as many and Shane wasn't able to sit down on them like he did against Margie because Cotto actually has a defense. Seriously, Shane was teeing off on Margie's ****ing head.

 

Rico, this post alone proves you know next to nothing about chins, power, punching effectiveness, and styles. Sorry.

 

Who wins in a battle of the Glass Jaws:

Herbie "The dancing canvas kisser" Hide vs Audley "King of Oxygen" Harrison

 

...And shattered his jaw.
