I have another source that claimed there was not a layer of muscle but a boxing glove hidden inside his head.
Thats why he has an 88% KO rating right? Or why he has 43 KO's out of 49 wins, and why he knocked soooo many people out cold, and put Carmine Vingo into a coma.
Sixto Escobar(Puerto Rico's first world champ) was never hurt in any fight.He had 75 or something like that.
Great mention. Others in the same league are Kid Gavilan, Billy Graham, Panama Al Brown, Jack Britton, Harry Greb, Sandy Saddler, Carlos Monzon, Tony Canzoneri, Barney Ross, Ray Robinson, Benny Leonard, Duilio Loi, Ismael Laguna and Sammy Angott.
Perhaps, although I don't know how many punchers he faced. Sammy Angott faced such debilitating punchers as Ike Williams, Henry Armstrong, Ray Robinson and Lew Jenkins multiple times, and was only ever stopped once when he quit on his stool. Willie Joyce is another who deserves to be mentioned. Some of these men were exceptionally tough.
Actually, who can find the most amazing record, durability-wise? Take into account their opposition, how many times they were down or stopped, under what circumstances they were stopped etc. I'm tempted to go for Jack Britton.
Ali was knocked down three times in reality, if we're talking head blows not 'tripping over boots' blows. And he must have been over 50 when "Bert Cooper" floored him. ps. Hagler is one of the better choices here, perhaps the best. :bbb
Although I would replace him with Monzon if we were talking about cuts stoppages as well - tougher skin.
