This is the second best fight that could be made, but I still find it hard not to be disappointed about the collapse of Mayweather - Pacquiao.

I do think, like Legion said, that Mayweather has the ability to make Mosley look old. Still, it's a compelling fight between the two best welterweights in the sport, both of whom are considered top 5 P4P fighters so it's definitely something to get excited about. I'm picking Mayweather to win by wide UD. Maybe I'm underrating him, but I'd be surprised if Mosley won more than a couple of rounds.
