This is when the fight should have taken place. Pacquaio went 6-0 (2) during this stretch. Mayweather went 3-0 (1). Pacquiao beat Hatton KO2, Cotto KO12, Clottey W12, Margarito W12, Mosley W12, and Marquez W12. Mayweather beat Marquez W12, Mosley W12, and Ortiz KO4. Pacquiao had beat Diaz KO9 and DeLaHoya KO8. Mayweather had beat DeLaHoya W12 and Hatton KO10. Pacquiao would beat Bradley but get robbed on the scorecards. Mayweather would beat Cotto W12. Who wins?
Not much different than the actual fight except Pac takes more risks, walks on to more counters and ends the fight looking more busted up than the 2015 fight.
