I'm not a fan of Berto either. He's got a very peculiar style which doesn't fit my tastes. But I think Pacquiao would rather easily tame him and crush his ambitions.
On the other hand, I don't even see Mosley beating Pacquiao... And I'm not that anxious to see Pacquiao-Marquez III... I wanna see what perhaps any other boxing fan wants to see... Pacman vs Money... Will that ever happen?
