Money Mayweather would win....he's still undefeated. :D

Floyd Mayweather in his prime would destroy Bruce Lee in his prime but also would have been murdered the ring by Ali

^^^ I agree because of the weight and reach difference.

Mayweather is more of a defensive boxer....I've never seen him take a direct punch.
I've been to two of his fights and watched most of his others on tv....boring. But it's made him a lot of money.
