He didnt back off, but he made it clear that it's very expensive. I think it was over 100K, so quite a sum. But I believe that was for OST; testing like it was for Floyd-SSM. Less than that will do IMO. Both fighters should subject themselves to random testing and the threat alone should be deterrent enough. That's (part of) what's being done in cycling which is the frontrunner in anti-doping. Random out-of-competition testing. That's the way forward. Nobody likes cheaters and we all want a level playing field. This issue needs to be solved or else the suspicions will get more and more tiresome.
Of course. This OSDT gimmick was all dreamed up to justify the biggest duck and doge in history when Mayweather did everything he could to get away from Manny Pacquiao.
It's a lil ****ed up to ask at this point in the fight instead of upfront, but I can see his reasons. I can also understand the reasons for not wanting to on part for Ward.
