The welterweight division has the winner of Cotto-Clottey, Mosley, and Berto, and maybe Paul Williams if he can get back down. I can't see any of these guys fighting Margarito again.
There is a lot of depth in the division but not a lot of big fights.
Also besides Guzman, I don't see Bradley or Holt as exciting fights for Pacquiao IMO he beats both of them easily, so do any of hte top WW and Mayweather.
