:yep pac, margarito, calzaghe and even jmm has a very good stamina. juan diaz and katsidis deserves a mention.
Mayweather has great stamina, but he doesn't have nearly as much output as the other great horses on this list. Still he has great stamina, but I've seen him take time off in some rounds. Juan Diaz is definitely one that has great stamina. Calzaghe & Pacquiao are tops too, but people haven't seen enough of Berto to realize that that guy has some serious lung capacity. Considering that he puts way too much on his punches, it's unreal that he doesn't punch himself out.
Definitely, forgot him too. Watch the Kostya Tsyzu fight. That should tell you why. He's a ferocious body puncher, and usually attacks from the beginning to end. He's had problems with stamina at 147 though and as he's grown older, but he has solid stamina for the most part and outworks people.
Damn, I expected the usual uproar from the Pac fans for my vote. Looks like they're learning to control themselves. I was obviously joking, as his stamina is among the best in boxing.
Hopkins might have to be added to this list too. He paces himself very well, and I haven't seen him tired in a fight.
so you just go by whatever someone says online, unverified? He was joking It's Manny Pacquiao, the Engergizer Bunny.
