I love Chael, think he's hilarious, but Floyd's opponents are not tomato cans that nobody's heard of. His last three I will admit were much less known than his previous opponents like De La Hoya, Mosley, Marquez and Hatton, but there's almost nobody left for Floyd to fight.
This is what I would like to see happen, even though it's almost certain that it won't: Pacquiao beats Brandon Rios in China decisively (preferably by KO/TKO). Mayweather fights the winner of Bradley-Marquez next May (even though I don't like Bradley, I hope it's him for the sake of this because Floyd already trounced JMM four years ago). Around the same time, Pacquiao should have a fight against a formidable guy, not sure who, but it would set up a superfight between the two in September on Showtime.
