I was wrong about the tablespoon then. That is such a small amount of blood there is noway you can't be suspicious of Pacquiao if he doesn't submit to the testing.
It doesn't matter the amount of blood, it could be 1 drop, the point is it's not necessary! Urine analysis can detect everything they would be looking for. The Mayweather camp is just using this to get out of the fight. And if Pac agrees as he had 2 earlier times, they will just come up with something else. I think Floyd will win this fight, but I'm not sure he has the balls to fight this fight!
don't think its happened in boxing before. But let the biggest fight in awhile be the example that the rest of boxing should go by from now on.
