I'd have to go with Duran anything above lightweight. but even at lightweight In the first fight it's Duran in a rematch it's a toss up. Duran has too much ring savvy. Pacquiao would get very frustrated and would have to learn how to deal with Duran's clever use of the body. Even with Roach in pacquiao's corner, it will take a second fight for Pacquiao to be able to coup.
