If Cotto loses, then I don't see him fighting Margarito next. He'd probably take a step back and fight an easier opponent. That'd be a tough assignment for Cotto to fight Margarito coming off a defeat to Mosley.

If Cotto beats Mosley, his stardom and drawing appeal will be higher than ever, and he and Arum will go after a superfight with Mayweather for Summer '08. If that fight didn't happen for some reason, then you could see a Margarito fight as Plan B. But there'd be too much money to be made from a Mayweather-Cotto fight, I think both sides would be ready to strike a deal.
