They just want a big fight for Mosley. They're not worried who wins Manny Cotto, whoever it is is promoted by Arum and they're not part of the deal of any future Manny/Cotto vs. Floyd fight. I think Floyd will fight Cotto if Cotto beats Manny, he'll have more leverage in the negotiations and it'll piss GBP and Mosley off. I'm sure Floyd would like to do that after the Kellerman ambush. If Cotto did beat Manny it would be a much bigger fight than the Mosley fight anyway. I'm pretty sure Floyd will fight Mosley at some point because he needs to pile up as much cash as possible before he quits again.
