Re: Best chin from this list: Muhammad Ali, Vitali,Marvin Hagler, George chuvalo
Chuvalo had a good enough defence to not get hit on the jawline too much.
He obviously had a very good chin anyway but went in survival mode every time he got hurt.
Ali in the 60s got really hurt by a left hook from Cooper.
In his autobiography he said foreman took him to his limits a few times.
Vitali has been hurt but never been down, has a lot of confidence in his chin.
Except Corrie Sanders if you want to count that as a KD
Hagler is the most proven of them all.
