Conner seems to have awful stamina and gassed out after 1 round against Diaz he doesn`t know how to pace himself and MMA fighters dont seem to do stamina building road work because they only fight 4 rounds, if MMA fans think he has a chance against Mayweather do they think he could`ve won a points verdict against Floyd over 15 rounds or a lesser boxer? Do MMA fighters have bad stamina in general?
