If drug use is so widespread in sports as those that say anti-doping policies needs to be revised, do you really think the Olympic style testing from WADA and USADA is an appropriate model for any professional sports organization to follow when they have such a failed history? While there may be widespread use, why should boxing take advise from a drug expert with no background in sports or sport medicine? The appropriate experts are the nutritionist, trainers and conditioning coaches.

Rules are made for people that follow the rules. Those that don't, don't care what rules you use because they are not bound by them. If Anti-doping policies are going to make a difference in sports culture, then there has to be fundamental changes in the ethics of all sports, armature through professional. That is impossible.

Even if the rules are changed for more stringent testing procedures to catch users, it won't change the culture, It will only affect it's appearance.

The commission could be more positive in it's stance by promoting boxings biggest stars and taking the lead to show both fighters are 100% clean. By removing any doubts and speculation.
