What would Mayweathers record be against Mosley, Cotto, Paul Williams, Joshua Clottey, or Vernon Forrest?
Mosley, Cotto, Paul Williams can and will beat Mayweather. Clottey and Forrest have a chance as well. To be honest , if Mayweather fought these guys he would have more losses than wins. I think he will beat JMM but he will get KOd by Pacquiao. Mayweather’s record of 38-1 of course is controversial since all of these guys you mentioned are way better fighters than Judah, Baldomir, Hatton, De la Hoya, or even Castillo.
