The point I'm trying to make is that Pacquiao has too much too lose if he happens to come up hot on a drug, especially one after the fight. Sure, whatever damage he did to Floyd would be already done, and no, Floyd would take no pride in being right, but...what I'm trying to say is, I don't think Pacquiao would risk the backlash...
2. Nobody is scared...not Pac, not Floyd. That side of the conspiracy theory is just ridiculous. The evidence points to PBF being scared. He said himself 'I will never lose to a smaller man' Pac was the smaller weaker man and looked beatable to Mayweather until Pac fought Cotto and Walked through his biggest punches and knocked Cotto around like Pac was the bigger stronger man. If you also take into acount that PBF hasn't fought the biggest, strongest and BEST fighters in the the Welterweight division it starts to become even more clear: Clottey, Cotto, Margharito, Berto, Mosely. Mayweather is also terrified of losing his '0'
