That's clearly a fat and not a rehydrated man. You should probably understand how weight cutting works before writing idiotic, yet assertive posts about the subject. GGG has said he'll fight anyone from 154 to 168. GGG is built for the 160lbs amateur division, there are junior welterweights his size in the pros.
No need to be defensive, there's nothing idiot about what I said. Floyd barely goes above 150 on fight night and isn't even fighting Alverez at the 154 limit. So yes, it's a waste of time even suggesting the fight. Mayweather already said he only wants to fight people at their comfortable weight.
