Margarito and Toney have mammoth chins. But, I give the title to Margarito. Hes the best Ive seen that can take a power shot, and in an instant return a power shot right back. He doesnt care about covering up, but just delivering. He will even smile after getting hit hard, I think the guy loves pain. I think Holyfield is the greatest pound for pound all time. Im curious to see if Chris Arreola has a mammoth chin. If he does, look out.
I'd say: 1.James Toney 2.Antonio Margarito 3.Bernard Hopkins Kelly Pavlik very very nearly got KO'd in the 2nd round by Jermain Taylor, who isn't exactly Earnie Shavers. Joe Calzaghe has been floored by Kabary Salem and Byron Mitchell- he has a good chin yes, but I don't think it is as good as the top 3 guys mentioned above. James Toney is a natural middleweight who can stand and slug it out with a fully fledged, full sized, power-punching heavyweight in Sam Peter. The guy's natural resilience is incredible. Honourable mentions here to Oliver McCall and Vitali Klitschko.
Andrade because he got hit by Kessler who is a big puncher and Margarito because of Cintron also Cotto who are big punchers.
Peter has shown he can't take hooks he can only take straight punches. Peter has chin issues when he is not hit straight on.
Steve Forbes is a good shout. I would have to say Margarito. Not only his ability to take the punch, but fire back straight away and continue walking his opponent down.
