Good point. His chin did hold up to the initial punches of Hagler and Barkley and Leonard. And he took a good Duran right hand in his fight with Roberto in 1984. Problem with Hearns was more stamina. He took alot of Hagler's punches in 1985 and did not fall when other guys would have, yet then he is stopped. Just seems like his chin was not dependable, but it was not necessarily weak. With his body you get that big leverage punching and the long frame which does not absorb good punches sometimes. Look at Bob Foster. Foster could punch like heck and landed so well at Light heavy that his chin was not exposed, but at heavyweight they could take his punches better and then he was clocked. That long frame did not absorb. Hearns and Foster are the cream of the crop of that style of fighter who is stretched out. Other guys like that were Breland who is not in the Hearns and Foster class since Breland was just a little too weak. Milton McCrory was that king of fighter although Milton had a 73 inch reach.. So he was tall but not that good a reach,,..
