Wait, correct me if I'm wrong but wasn't it Pac-man who refused a drug test?
It's not like they take a pint of blood, they would only need a little bit. It wouldnt exactly hinder Pac's performance in any way. Besides, Mayweather would be subjected to the same thing anyway.
im kinda with you on this one, i cant stand boxing one way or another but it seams like pac's the one that said no, superstitious or not mayweather has to do the same things too, it seams like paq is the one with something to hide
