I think it's an integrity issue or at least supposed to appear like one. No matter your personal feelings, and the "everyone's doing it mentality" this information shows without a doubt that Sonnen was cheating. Sure he gives good sound bites, but I suppose fox is trying to keep the thin line that remains keeping the UFC sport and not fully sports entertainment.
In my opinion Sonnen would have served himself better to show his integrity and retired when the trt era ended, it's a shame, he seems like a cool guy, it's just that he was always firmly on the sports entertainment side of that argument, and though I believe we we "sport" types are clearly losing that war... I am happy with any small victory we get.
