The weights probably make your power more "natural" meaning you're more used to throwing punches harder rather than trying to throw power shots. If nothing else, it makes you feel lighter in the ring and maybe gives you more stamina going down the stretch.

I agree. Mosley is such a nice guy; nobody has a bad word to say about him. Even Oscar is mum and he was the other party to that match (being business partners probably has something to do with it). If it had been Bernard Hopkins we'd all be ready to toss him in the garbage can.
