When you compare his workouts to footage there is of victors workouts, it seems at first glance that mayweather has a different standard of workouts. though it is very likely that both fighters havent shown their real conditioning workouts to the public.
Compare those with video's of Mayweather training for DLH and you will find he his hand speed has slowed down alot. But I've seen many recent video's of him training with weights and strength training so he's probably trying to convert into a fan friendly fighter.
