I expect this is nothing but one big PR
exercise. The UFC is the one doing the tests and Dana doesn't give a damn about roids, otherwise he'd never have signed Overeem, given such an easy acceptance to TRT etc.
So what if they do random tests? They're by the UFC for the UFC. Is there some guarantee that they don't turn around and flush the tests right after they get home? Is there even any assurance that there are tests being done? Internal auditing is no auditing. Get VADA or a neutral third party involved, then I'll be impressed.
Heck, Chael Freaking Sonnen of 16:1 fame is praising this, that in itself should tell you guys what a laugh they're having at the gullible fans who believe this.
