Danny Williams when he dislocated his right arm and came out with a left hand knockout by knocking down Mark Potter three times
OMG give it a rest already!!!! LOL Id say Calzaghe in response to the thread, and good call to who mentioned Mayweather and mental toughness, ive never seen the guy lose his cool when things arnt going his way.
so many honorable mentions, but pacman, margarito, vasquez, and jmm all come to mind. i mention jmm because not often do many fighters get off the canvas multiple times to put a masterful performance at that level of the game. any of those guys are great examples
Also JMM showed grit towards Manny Pac in both fights, Pac-man said Eric Moralez was his hardest fight even after the second fight with JMM. I would have said JMM.
Vazquez for sure. Sugar Shane deserves some love to be honest. Takes a lot of heart to fight margarito.
