Mayweather is scare of Pacquiao but he wont scape

This drug test protocol is ridiculous. Mayweather and his people know Pacquiao is clean but the guy is playing mind game by one side and by the other trying to chicken out. Pacquiao is accepting the blood and urine tests right after the fight, so what? Pure skills has proven to be more effective than any other thing in boxing, so if Mayweather is so confident he has by far more skills that the Pacman, why don’t dropping these stupid drug test request and sign the fight? This is unfair to Pacquiao, all boxers should be tested equal or if is so simply to success just using these drugs why isn’t everybody else on it?
