I think Mayweather, but he would have to do some different things, like take more of a chance offensively, otherwise Pacquiao could jam up Mayweathers offensive flow, and how he can now mix it going forward and staying back with improved skills of late.

Mayweather by decision, just. BTW.....it doesnt matter if Pacquiao beat common opponents more easily, as different styles produce different results. Pacquiao was impressive, bt if Floyd is sharp v Marquez, I choose PBF by decision.
