that's great
doesn't mean shit against that sort of physical disadvantage
he is 5'10" and 220lbs, that's plenty big. That much weight on that short of a frame allowed him to generate beastly power
Mayweather is 5'8" and less than 150, not even in the same class, he's a twig that would get snapped in half
It's true that once you reach a certain size, additional size isn't always an advantage. It's why the heavyweight class can span such a huge range of sizes and still be competitive.
But that is absolutely, categorically not the case when we're dealing with the manlet sizes Floyd fights at.
again you're ignoring the fact that he's a manlet and will get manhandled by those monsters
