You have to hold back your judgements/attitudes/racial biases (for some) for a second and listen. Jon Jones does have a history of messing up, I am not denying this for one second. But when we attempt to claim he intentionally took supplements we are - in our own way- discrediting his accomplishments in the cage. If we look at the objective facts, in both cases USADA (the major organization responsible for examining the scientific information and passing judgment) agreed that both of these were a result of unintentional error such as contaminated supplements. If you believe Jon Jones cheated intentionally, you may as well say Lyoto Machida cheated intentionally, as he was suspended too. You may as well say Mendes cheated intentionally. Last point, separate from this thread, but PEDS don't make you throw perfectly setup high kicks.
