Marvin Hagler had a ridiculously good chin. He took Hearns's best right hand shots, and his chin broke Hearns's hand lol. Oliver McCall Sugar Ray Robinson, his chin is one of his greatest assets.
Vitali is an interesting 1 for me, not sure i mean he took some savage shots against lewis however he was in a lot of trouble against sanders, i am not sure (i know sanders is a big puncher)
:good When you think of chin they are the ones who immediatly spring to mind, likeswise with Jackson and Hearns in ther power department
Chavez, hands down. It's why he won many of his fights. (not that he didn't also have skill and great aggression.) Supposedly his head was x-rayed once, and found to have unusually thick bones.
