I think everyone knows about this, especially the matchmakers of Top Rank. It is the reason why it took them years before they allow Pacquaio to face Marquez for the third time; they thought the change in the weight will severely affect Marquez, but it fell flat on their face. Stylistically, Marquez is a nightmare for Pacquaio, and is Mayweather. Arum won't give Mayweather a chance to embarrass him at the same time, earn the biggest pot in the history of boxing.
