First, let's just assume that Manny Pacquiao will get another gift decision over Juan Manuel Marquez. It's inevitable that the judges will be under pressure to right the alleged wrong done in the Timothy Bradley fight. The next question is who will he fight next? And let's take Floyd Mayweather out of the discussion since as long as Bob Arum is involved that fight will never happen.
Depends IF he (Pac) wins or not. Tim Bradley would be the ideal choice for either a JMM/Pacquiao winner.
most obvious is floyd, but if he can't get his 15lbs. of muscles back, bradley or rios. 1st option should be bradley especially if he beats somebody noteworthy...2nd option, rios.
Floyd Bradley Cotto ? I guess you throw up the high ranked guys at 40-47. Matthysse Garcia Alexander Zaveck Malignaggi Brook Rios
Not many opponents left. Bradley for a rematch, brandon rios is being lined up. Amir Khan as a future opponent, but he's with GBP. There are some good jnr middleweights but can they get them to drain themselves for the payday. A few jnr welters who can come up but wont be beating him. Opponents are running out it's either repeat fights, time to retire or fight once a year like floyd
If Pacquiao wins by gift. He should fight Bradley. In fact Bradley should be his next oppoent if his win is honest.
In the scenario Pacman gets another gift, most likely it might be inhouse. I believe even Arum was very interested in a Pacman-Rios fight. Pacman-Cotto at 154 another strong possibility, but those 2 most likely at least while Pacquiao's still under contract with Arum.
He needs to fight for a title so Malignaggi, Alexander or Bradley if they still hold their titles would be ideal. He could go for the WBC strap though.
