Why hasn't that same 80percent ow up at any of Marquez's other fights? Because Mayweather is the draw. Granted the majority of the fans may come to see him lose, but they come to see him... In boxing being a vilan does pay. People will always want to see you lose, and try to do what they can to help the boxer that they want to win, which is to come support them, and hope that that will help boost them over thier opponent.
