(Seen here: Something Thiago Silva has not able to honestly do since 2009.)  If you thought Matt Riddle was just blowing smoke up our asses when he criticized the subjectivity of the UFC’s hiring/firing policy on The MMA Hour a couple days ago, look no further than Thiago Silva for proof that he wasn’t. The Brazilian slugger has not only failed two drug tests in his past three bouts, once for using synthetic animal urine in an attempt to fool his post-fight test at UFC 125 and once for marijuana metabolites at UFC on FUEL 6 last November, but has gone 0-2 in the bouts he actually managed to show up clean for. Combine that with the fact that he nearly costs as much to show as that super fucking expensive Jon Fitch and you’ll be left wondering how someone so incompetent still holds a job in the sport’s highest promotion. Our guess: DW and friends really appreciate the fact that — on the off-chance Silva isn’t trying to cheat the system or cheapen the value of a win — the dude brings it.  Whatever the case, Silva will be given what we can only assume is his final, final chance at UFC 162, where he will meet fellow piss test savant Rafael Cavalcante.
