Good theories... Quite a way outside of my scope of boxing knowledge but i will say one thing... Corrales who was 6ft 1ins blew up to 160 in his fight with Clottey after weighing in at 147.

Now if a guy standing at 6ft 1 only blows up to 160 then I just can't see Mayweather getting near that kind of weight on fight night.

My point being; I'm pretty sure Mayweather doesn't have to cut too much weight to make 147.

But like i say, sports nutrition and 'explosive' weight training ain't my thing



P.S Im also pretty sure Tommy Morrison became a punching bang when he stopped juicing.
