He suffered one of the most and gruesome injuries ever in the octagon at UFC 168, many people didn't believed he might come back after such a devastating injury, it really sucked to see the REAL GOAT going out like that.
People here love to talk shit about he is not the goat anymore, how he doesn't deserve to be in the goat talks, like his career and everything he did automatically get disqualified but they NEVER mention his broken leg.
I honestly believed he started to using it after UFC 168 to recover from his broken leg, that is way he was able to recover so fast and I have to agree he might just like the taste of the juice and that is why he might have failed his latest test, this is not like Jon Jones when he got busted right during his very prime.
People love to give a pass to sherdog darlings like Cro Cop, Ortega and Machida, I feel Silva rightfully deserve a pass too mainly because he didn't pope during his GOAT run, the best run in all UFC
