I been reading up on here ..and on the topic of glass jaws a few names get mentioned .. Amir Khan ,James Kirkland to name a couple... i mean they even claim Roy J Jnr has a glass jaw ... What are the unspoken parameters of glass jaw-ism ..lol my belief is ..Khan got clocked by a shot he never saw ..thats usually bye bye for most ..ask Paul Williams ..that doesnt signify a Glass jaw ...Maidana is a know puncher , Khan took it and stayed on his feet .. Kirkland ?? ok the jury is out with that one RJ Jnr ..i think he got an average chin ...and if yu slow down and and get caught they way he did ...it wud be over ... Dont forget some fighters style is to take some to give some ...they are the granite chin fighters ...Katsidis , Mayorga etc Others are to box and be elusive ...if caught and caught flush its possible ..its curtains ...does that mean they have a glass jaw ??? Ali went down to Fraziers left Hook and Coopers Right ...yet his chin was never in question?? Tyson went down several times in his lata career ..his chin was never in question ... Holyfield ...superhuman chin ...been down tho see my question??? what determins glass ???
There are, in my view, two main ways to determine that a fighter has a china chin: 1) If he gets knocked the **** out early, particularly if it happens more than once. Getting knocked the **** out at any time at the very least raises substantial questions about punch resistance. 2) If he hits the deck often, particularly against light punchers. This is usually not indicative of someone who has as bad a chin as number one. Bottom line - getting knocked unconscious is the best indicator of a glass jaw. And Khan CERTAINLY has one.
According to today's fans it seems to be anyone who has ever been knocked out, knocked down, stunned, or in some cases even slipped.
Simply put , i'd say a boxer who demonstrates practically little to no punch resistance. The type of guy that reacts everytime his chin is checked. No matter who you are you can be knocked down or out. So I wouldn't go as far as to say just because a fighter has been stopped he's "chinny". But You also have those tommy morrison types that seemingly every time the got hit with a flush shot they go down or wobble.
On ESB, you have a glass jaw if you are in any way hurt (even momentarily) by a punch to the head. You're also EXPOSED when you lose a fight. And you're a bum if you aren't elite p4p fighter.
Barrera got ko twice and you wouldn't say he has a glass jaw people over exaggerate to much and just want attention
I'd say Enzo Maccarinelli has a glass jaw. Andrei Arlovski in MMA. But I wouldnt say RJJ, Hatton or even Khan have one.
