I would say Pacquiao, Mayweather & Marquez are too small to fight Williams, and both Cotto & Mosley will duck him as they are (if Floyd & Manny are ducking them, then they're duckin Williams). Only possibility at 147 would be Clottey should he beat Cotto, but maybe Arum would keep him away. Forrest won't fight him, Kirkland is in jail, leaves Martinez & Dzindziruk who aren't money fights. The best bet I think is Pavlik at 160 if he can get him.
