He's a moron, and a hypocrite. And he just pissed away his re-match...literally.
Sonnen, 33, of West Linn, Ore., was apparently concerned enough about the possibility that he would render a positive test that he told CSAC executive director George Dodd he used an illegal performance enhancing drug leading up to the biggest fight of his life.
"He only indicated that he was taking it but he never indicated why," Dodd said of a conversation he and Sonnen shared during drug testing conducted by the state a day prior to the fight.
Sonnen "just let me know he was taking [something] and that's when I called over an inspector to get it documented. But when you do take it you still have to show a medical reason."
Looks like he told George Dodd about it at the weigh-ins... http://sportsillustrated.cnn.com/2010/mma/09/20/sonnen.drugtest/index.html
Mike...your understanding of this would be better than mine...but why wouldn't the commission then step in and subject him to testing at that point? Or are rules set in stone that the testing takes place after the match all the time?
A better question is...they caught Barnett a week before the fight occurred...how was Sonnen not subject to drug testing during training? If he was, why would he have started doping that close to the fight itself? Supposing he had his last test a week before and passed...I don't think it would've provided much benefit that close in would it?
