do you think pac uses performance enhancing drugs?
i think he probably does. there were a number of ways to respond to floyd's drug test requirement: agree to the tests; agree to the tests and plan a libel action at the same time; agree to the tests and respond with more requirements of your own at the negotiating table; agree to the tests but still make the same complaints in the media that they've been making, which'd still make floyd like a scared asshole while securing the fight nonetheless; .... but instead they chose to quit the fight. the pac camp knew that refusing the tests would be a huge public relations black-eye, that it'd sully the reputation of the world's most popular boxer and prevent the fight-of-the-century from happening, but for some reason they felt committed to doing it, felt they just couldn't agree to the tests.
if pac really does react badly to taking blood, does it really hit him so bad that's he's willing to tarnish his reputation to avoid it? or if he wanted to make an ethical stand and make floyd look like an asshole for introducing extra stipulations, he would have achieved this better if he'd complained about how silly the tests were while still going ahead and agreeing to them.
it's far from certain, but it looks more likely that he's using the drugs rather than not.
of course, he's still a great great boxer, and a great great credit to the sport (more than can be said for floyd). i guess he's got a choice - stop the drugs, do the test, go into the fight unroided and (probably) lose to floyd, thus causing people to question your entire career; or stay on the drugs, beat some other people and protect at least some of the pacman aura, ready for your post-boxing political career. it's not a surprise he chose the second.
whether floyd's an asshole or not, whether this was an unfair thing to ask for or not, it looks like pac's probably been using performance enhancers.
