Floyd Mayweather Jr would beat the shit out of Williams and Cintron on the same night

Nah, you gotta factor in the fact that Mayweather doesn't go for the KO so each fight would probably last for all rounds. I'm not sure how good he'd look for 20+ rounds. He has the skill to do it though.

Joe Calzaghe and Ricky Hatton have a bigger fan-base in America then Williams and Cintron. I found it hilarious how HBO ripped on Williams and Cintron saying they don't have fan-bases even on the East-Coast which where I'm from! Now when two british/welsh fighters are more known and have a bigger fan base then two American fighters, don't you find that odd?
