Where boxers fought much more frequent and say the time when there was 15 rounds. I think someone like Pacquiao who is constantly in shape and would have the stamina to go the 15 rounds, I think Mayweather and someone like Andre Dirrell may also be able for it, although both would have problems in certain aspects, such as the hand trouble Mayweather would have if he had to fight alot more often. Who do you's think?
Toney would've done it despite being perpetually out of shape. actually it might've helped him Hopkins easy MAyweather no way. injured hand problems
It's tough to say, I remember reading how Sugar Ray would sometimes fight 3 times in a month all 15 rounders, that's pretty incredible.
