To get peoples opinions you'd be better off reading one of the other thousand threads we have like this going already.
There comes a point in a boxer's career where moving up in weight without impacting negatively on performance becomes increasingly difficult. Pacquiao already moved up seven weight divisions since his junior flyweight days therefore it's reasonable to think that he's reaching that critical point or close. Pacquaio is an exceptionally determined and capable fighter yet I wouldn't give him a great deal of chances to beat Hatton, sorry.
