Re: Best chin from this list: Muhammad Ali, Vitali,Marvin Hagler, George chuvalo
Chuvalo and Hagler are both granite chinned. I wouldn't pick anyone in history to knock either out, around their natural weight division. Chuvalo couldn't be stopped by anyone in history and I wouldn't pick any light heavyweight, including Foster, to knock Hagler down or stop him.
Ali didn't have the greatest chin on the list, though his was excellent. He was one of the toughest fighters of all-time though, with an enormous heart.
Vitali has a good chin but he's not been tested enough. Sanders and Lewis both hurt him, so he isn't impossible to stop. He isn't a tough man either and is prone to quitting.
