Pacquiao's going to fight Juan Manuel Marquez—yes, again. But every fight Pacquiao has taken for the last few years has something of "when are they going to get to the fireworks factory?" about it. When are we going to get the damn Mayweather fight already?
There have been two sticking points. In the first, Mayweather actually had something of the moral high ground, even if he was probably just being a dick about it. Mayweather wanted Pacquiao to undergo Olympic-style drug testing, including a blood sample drawn the day of the fight. Mayweather does this for all his matches, but Pacquiao demurred, preferring the less invasive Nevada SAC guidelines. There was no agreement; the fight, scheduled for March 2010, was called off. (In the wake of that, Mayweather accused Pacquiao of doping. Pacquiao brought a defamation lawsuit. Mayweather has been dodging his deposition, and has been ordered to pay $114,000 in legal fees.)
