Hatton/Mayweather winner for sure, that fight would be great for boxing and make both fighters good money.
Mayweather or Hatton However, I expect his next opponent to be Yuriy Nuzhnenko because I believe that will be his mandatory. Expect this fight in March. In May or June, I see him facing eithe Oscar De La Hoya or Antonio Margarito. If he can get past them, then a fight with Mayweather will be made. Or perhaps a fight with the winner of Williams/Cintron.
I picked Margarito because he is the only one left that won't be busy. Plus if Mayweather wins I think he will fight the Williams vs. Cintron winner.
