Great point, I never really thought about until I saw Mayweather do it in his last fight.
Shows tremendous skill, patience, training, etc not to just get the insta-win when it's there. To have the confidence to basically air the fight out for whatever reason is remarkable.
Great point about USADA also. I dk if they went this overbearing drug policy route due to legal concerns or what but it is hard to argue the sport is anything but clean, to it's own detriment - but could possibly stave off future lawsuits/whatever if somone got hurt really bad from some roided out/PED monster that's out of his skull.
The head of USADA was on Rogan and the guy is basically judge/jury/executioner for all things PED and he is not fucking around. It's almost like he's getting paid on commission.
