“Sounds like Pacquiao has something to hide no?”
That’s what Mayweather wants you to think so he can chicken out of the fight.
Ask Floyd which of his other fights used these special extraordinary blood tests BEFORE the fight. None. Pacquiao has volnuteered to have his blood drawn immediately following the bout, but somehow that’s not good enough for chicken-hearted Floyd.
Too much $$$$$ involved for Mayweather to want out
Maybe just a head game
