I don't give him much chance at all. Too old, too small, too worn out. But if by some miracle Pacquiao beats Thurman. Would that move him into top 10 ATG??? He's already somewhere between 12-18 or so. Easily the greatest p4p fighter since Roberto Duran and SRL. And he's right there with Leonard as it stands now. The CV of Pacquiao -Flyweight to Welterweight -Destroyed Miguel Cotto -Destroyed Marco Antonio Barrera -Absolute wars and basically dead even fights with Morales and Marquez - 25 year career Imagine if 40 year old Pacquiao pulled this one off.
