Mayweather is trying to turn the tables on Pacman, but why is he making such demands? He isn't bigger than the sport and he has never done this with any other opponent. It's just typical Mayweather.
At the same time, why Pacman won't do the test I don't know, but it does make you wonder.
None of them come out of this well, you're right. Too many excuses for my liking, do either of them really want the fight?
