I agree; I think Camacho had a good chin, but it goes back to what Manassa said earlier about survival instincts. That and chin are a different thing. Camacho had both I think. I was just arguing about weight gain.
McCall is definately my pick. Seriously, people need to WATCH Lewis-McCall II. McCall wasn't even holding his hands up during the "quit round", he took a RIDICULOUS number of right crosses from Lewis (who was throwing everything he had towards taking McCall out), a very hard puncher himself. McCall was just walking around the ring taking clean shots to the head, and he wasn't even fazed.
I had forgotten that Ross went down a few times against Garcia in '35... that demotes him. As for Napoles's chin -strictly speaking it was great, of that I have no doubt. My definition of a elite/great chin factors in more than yours however... Ross was never stopped but he went down -he's no Hagler. Napoles was stopped, and I detract points based on that -whether it was for cuts (damn near always the case with him) or his corner really doesn't rehabilitate the fact that he was stopped. I factor it against him in terms of chin. In the last minute of the fifth, Napoles was stunned by a series of hard shots. He went backwards and stopped punching to regain composure. He took the shots, but he was stunned, if not hurt... in the sixth, yes, he was standing at the end, but he was hurt. I wouldn't put him at the top based on this fight. ...I do agree that the more youthful Napoles would have handled the Monzon onslaughts better but we would not have such a clear measure of his chin -you take more shots as you age because that mind's eye that prepares you for shots is based on reflexes and those diminish markedly in your 30s. All you have left eventually is chin and will.
Round 7, Duran-Barkley. Barkley, facing the camera, wound up and nailed Duran flush with a left hook... then he winds up again and doubles it. Duran took these flush. Duran was taking monster shots in that bout that he shouldn't have. And don't forget he was a bit smaller than Napoles and Barkley was a bigger mann than Monzon. I'd argue that Duran's chin was slightly better than Napoles... but neither are in Hagler's league.
Why? I thought you read the same lines as me when it comes to separating raw durability from the ability to survive; there are many factors; defence, reflexes, cut resistance, counter punching (discourages attackers), stamina etc... If I'm not mistaken, we are talking about pure 'chin.' I don't think criticizing Napoles for being stunned against a heavy handed, larger fighter is fair. We never saw Hagler take light heavyweight punches.
Napoles was stopped 4 times in his career. Three because of cuts, one because Monzon landed too many concussive blows to his head. Napoles's inability to continue means to me that his chin was about to fail him, or that he was going to be hurt. Don't mistake me, he had a top chin, I just wouldn't put it up there with Haglers'. "Chin" is the ability to take a punch to the face. It isn't literally the chin area -it includes the temple and cheekbones and the end of the jawbone under the ear -all the nerve centers. Cuts probably shouldn't count, but I can't help it. If you get stopped, you get stopped. Perhaps I am confusing the argument; I just can't say that I'd place Hagler at the top if he was stopped 3 times on cuts. Great chins take monster shots. But the "best chins" don't acknowledge monster shots, the fighter doesn't skip a beat and the fighter isn't stopped -ever.
We'd have a better understanding of who had a better chin between Napoles and Hagler if a past prime Hagler took some flush shots from cruiserweights, which is about equivalent to the natural 135-140 pound Napoles taking flush shots from the 160 pound Monzon.
