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.
