The problem with Overeem, in comparison to Lesnar, is that there is plenty of evidence that Brock is a freak of nature, he had that massive size from high school if I'm not mistaken, plus, he got tested regularly during his NCAA career, so, it is far more plausible to believe that Brock is just huge, in comparison to A.O.... A.O. began his fighting career as a lhw... and then over months he became huge?? somehow... AO being clean isn't that easy to believe.... I'm not saying he's guilty, I'm just saying that it is hard to believe AO is innocent...
