Do glass jaws exist in boxing?

Why are cubans so terribly glass jawed? can a chinchecker answer this question?

they're the capital city of glass jaws. people talk about the brits being glass jawed frauds, but they have thousands of pro boxers

Cuba only has like 30 pro boxers, and among them maybe only 2 or 3 seem to have any semblance of good whiskers, the rest of them are a bunch of glass jawed jokes, no wonder why they tend to be defensive specialists, everytime you land something semi-solid on a Gamboa, Rigo, Lara, April, etc, it's bambi dance time.

 

I think with the upcoming holiday season we need ChinChecker university to create a bambi dance vid with Khan, judah and the crew lopetego mentioned

 

Na they don't exist
