why don't pacquiao and mayweather solve everything this way?

this is simple, random testing with a cutoff date, but they can test them even inside cutoff date, but if so, the fight is delayed for 1 or 2 weeks. Mayweather could even simply choose not test pacquiao in that cutoff date and pacquiao would never never test positive, knowing that it's possible that they test him in that so called cutoff date

the advantages will be that pacquiao will never be weak with this method, and he will be clean, and on top of that this way will detect cheaters, and cowards at the same time (if mayweather doesn't test pac inside the cutoff date he isn't a coward), also it can at the same time prove who are cowards and who are clean fighters, true intentions, and on top of that way the best boxer wins, his legacy improves tons of places in the all time list, etc etc, and if both are clean and both aren't weak, the best one gives a beating to his enemy in the fight, or well, at least maybe another more close boring result like a draw hahaha...
