Pacquiao's best option if no PBF fight?

[Rantcatrat]

Jumping the gun a little bit because PBF has until tomorrow to make a decision, but who do you think is Pacquiao's best option for an opponent if PBF chooses to not fight Pacquiao at this point in time? I have no interest in seeing him fight Cotto again even at 154 because I believe Pacquiao is a bad style match-up for Cotto at any weight and I don't believe Margarito deserves the fight at least not now (if ever). Maybe Shane Mosley? Tim Bradley? Marquez? Pacquiao has said in the past that Foreman was too tall, which eliminates Paul Williams and Sergio Martinez from the equation.
