Roach..
Roach is just too conscious of the percentage they will get in the fight. Of course, their camp believe that because Pacquiao is more famous and has higher market value, he must get the upper percentage of the payment but the other side doesn't agree with that. And plus the fact that Mayweather is afraid of Pacquiao. He doesn't want to mess his record and besides, he doesn't need to prove anything with Pacquiao.
