Fighters you suspect have a GLASS JAW 100%

[Rocky Balboa]

One thing that you said I agree with. That is PBF's chin. Many people think defensive fighters are the way they are because they cant take a punch. Personally, I am an extremely defensive fighter. But I can take bombs square on the chin without getting even dizzy. I have a great chin yet I love the "sweet science" too much to just sit and trade (something I call blasphemy ). Im sure PBF is similar. Take Ali as well for example.

Calm down son, you're not Sugar Ray Leonard yet

I agree though that assuming a defensive fighter has a weak chin is silly. The fact that Mayweather got caught by the likes of De La Hoya, Corrales, Hatton & Judah at some point shows that he has a chin that can hold up. Any fighter with 30+ fights (a lot at a high level) who has never been down from a punch has to have a good chin.
