If not Mayweater than Berto. People are only thinking for the short term with Mosley, it would make money but it wouldn't be as exciting. The Berto fight would make less intially but would be an exciting fight, Andre would get sparked but he's got the speed and size to make some trouble early on. Pacquiao would have rthe chance to be in a FOTY and he would be WBC Welterweight champ.
