If Pacquiao's next opponent is a GBP fighter....

If Pacquiao's next opponent is a GBP fighter, which one do you think would be the best/most credible opponent? Obviously the dust needs to settle with the whole Golden Boy shake-up. But these are a few opponents I'd like to see them consider:

Adrien Broner: He's called out Pacquiao recently. Although Maidana did expose him, it would be interesting to see Pacquiao fight against a "slick" fighter with a style similar to that of Mayweather's. He's very immature but I think his antics do create a buzz. I could see this fight possibly doing better than Pacquiao-Bradley because Pacquiao already has his loyal fan base but then Broner brings something different to the table that Pacquiao's previous opponents haven't.

Danny Garcia: Arum seems in favor of this match-up. I think Garcia is tailor-made for Pacquiao. In addition, Pacquiao has adopted a little bit more of a safety-first approach, so I'm not sure Garcia would be able to land anything significant on him. I think Pacquiao's in-and-out style would be very tricky for him. Garcia is a credible opponent with wins against Matthysse and Khan.

Marcos Maidana: I honestly think this would be the best high risk/high reward fight right here. He'd finally get an opportunity to "one-up" Mayweather with a superior performance against a common opponent. Something which has been difficult to do with the whole "cold war." Maidana I think would be open to doing this fight since he would certainly get paid well.

Amir Khan: I think this makes great sense for both fighters. Khan has been named as a possible Mayweather opponent. The whole story line with them being former sparring partners and Khan leaving Freddie Roach would make for some interesting press conference quotes. Virgil Hunter has recently gotten a bit more vocal as well so I could see some war of words here. This fight makes perfect sense for Khan. If he could somehow defeat Pacquiao, he'd for sure have earned his shot at Mayweather in May. Tough fight for both fighters. With Pacquiao's "diminished" power and Khan looking much bigger now at 147, this could be a tough fight for Pacquiao.

Just curious, what do you all think? What would be Pacquiao's best "next" opponent? Taking into consideration PPV sales, excitement, build-up, and lead up to future opponents (i.e. Mayweather)
