The Bradley fight bombed with Pacquiao, it would have to be on free HBO for Marquez.
Add to that, another Pacquiao loss and Pac's stock drops even further on the PPV market.
Not to mention a Mayweather-Pacquiao possible fight gets tossed completely out the window.
The problem here is that if Pacquiao loses, he's a dimished on the PPV market. I dont see Pac-Rios doing more than 1 million PPV if Pacqiuao walks in there having lost to Marquez.
