As Steward had said during the fight, Mayweather didn't look bigger, just tighter/stronger then Mosley, but Mosley has always been able to put more muscle on his frame then other guys his size.
I the weigh-in you can say Mosley's back was much larger and wider then Mayweather's.
I agree with the ts, Mayweather isn't a huge ww, he doesn't come in to fights having rehydrated 15 lbs. At this stage of his career i'd imagine he rehydrates at most, 6-8lbs.
Also based on my observation of the footage on 24/7 as well as the interview on fighthype, Mayweather actually looks smaller when he's not training for a fight.
