I know, it's not the fight we wanted, but it has the potential to be a very entertaining fight. Bradley (28-0 1 non-decision) is a young fighter, in his prime, and probably has the fastest hands of any recent Pacquaio opponent. Freddie Roach, Pacquiao's trainer, has compared Bradley to previous opponent Ricky Hatton who Pacquiao knocked out in the 2nd round, but if they believe that; they'll be in for a rude awakening.
The questions I have on Bradley are his resume and his defense. His biggest fights so far in my opinion have been against Devon Alexander and Lamont Peterson; both excellent fighters, but not in Pacquiao's universe. The way in which he won the Alexander fight though, stoppage after a headbutt, is also his best chance to win this fight. Bradley is famous for "accidental" headbutts, and if he "lands" one on Pacquiao; it'll change the fight. Some fighters handle cuts well and it seems they get a boost of energy from it, while others start to shut down and their aggressiveness drops; Pacquiao is one of the latter. That being said, I still think Pacquiao will win this fight because I don't trust Bradley's defense. Even against lesser fighters, Bradley gets caught with a few very flush shots in every fight. With the way Pacquiao moves and changes angles, he'll catch Bradley often and Bradley hasn't faced many guys with Pacquiao's power. On top of that, Bradley doesn't have much power (only 12 knockouts in 29 fights) and I don't think he's capable of hurting Pacquiao.
Prediction:
Pacquiao by Majority Decision 116-112
