Why doesn't he just agree to the 14 day cut off man? It's not like they're going to be taking pints of blood during the random blood test. Plus it's random anyway, there's no telling how many times he'll be tested or how much blood will be drawn. 14 days before the fight they won't even have to worry anymore.
You have no idea if that 14 days was even proposed though. That's what Mayweather claims now, after the fight was called off entirely.
All we know is there were 9 hours of mediation two days ago and they couldn't agree on the terms. Pacquiao's camp said their compromise was 24 days and mayweather never mentioned 14 days, Mayweather claims he did. So really as far as that one point goes it's a he said she said thing.
Further, Bernard Hopkins who's apart of Golden Boy may have accidentally spilled the beans when he stated that he thought the fight wasn't going to happen and that mayweather would fight shane mosley, pacquiao would fight "that jewish kid" (lol) and after they'd fight at the end of 2010. Hopkins said there isn't enough time to promote the fight and that all this is for publicity. He also said mayweather faked a rib injury against marquez to have more time to promote the fight and in the end did 1 million PPV buys, so it was a smart business move.
So really, I'm having a hard time believing anything Golden Boy/Mayweather say, as well as Top Rank/Bob Arum.
