Im not sure Pacquiao will even get past Marquez so lets not count our chickens just yet. If it did happen i would favor Hatton because he is so much bigger than Pacquiao naturally i really can't see Pacquiao beating Hatton at Jr Welterweight. And why in the world would Pacquiao want to go up to Jr Welterweight anyway ?? there are so many other matches at Super Featherweight/Lightweight that can happen. Like Joan Guzman, David Diaz, Juan Diaz, Michael Katsidis, Edwin Valero, ETC. I would favor Pacquiao in almost all of those fights i really think moving up to Jr Welterweight is a big no no.

And you said about Mosley moving up from Lightweight trying to compare that with Pacquiao moving up. Thats totally different for 1 Mosley started at Lightweight so it was easier for him to move up. Pacquiao started at Flyweight, thats 7 weight classes below Jr Welterweight. Plus Pacquiao hasn't even fought at Lightweight yet so we don't know how he will perform. I really think your expectations are a bit too high on Pacquiao just think logically about what weight class Pacquiao started at and your expecting him to jump up another 2 weight classes and beat Hatton at 140 who is the best Jr Welterweight at the moment ??
