Is the USADA program having the desired effect in the UFC, or is it actually an unwarranted intrusion into fighters’ lives, yielding little but questionable results? In this week’s Trading Shots, retired UFC and WEC fighter Danny Downes discusses the anti-doping program with MMAjunkie columnist Ben Fowlkes. Downes: Ben, I don’t know if you caught Frank Mir’s appearance on “The MMA Hour” this week. He was on there discussing his current two-year suspension for testing positive for a DHCMT metabolite. He claims innocence (of course) and went on to detail the trials and tribulations of dealing with USADA. Iain Kidd over at Bloody Elbow has an excellent piece debunking some of Mir’s claims, but I’m not necessarily interested in debating the effectiveness of this particular DHCMT test.
