The rules state he has to be in the pool for 6 months. The whole Lesnar debacle should clearly explain to you why USADA would want nothing to do with giving another exemption to a star athlete who "May" be on the juice. Conor's refusal to join the pool until now and his physical appearance certainly led credence to those who are accusing him of juicing. USADA never said Conor is on the Juice. That's your interpretation. They wanted him to follow the rules they were hired to enforce. The UFC didn't want to follow said rules, and here we are.
As to my second point, why didn't Conor join the pool a year ago, or 6 months ago? Conor and the UFC both know the rules, now they're crying about having them enforced when it affects their collective bottom line. They are demanding USADA grant an exemption after USADA got burned (BADLY) by the whole Lesnar incident. People have been accusing Conor of being on the gear for a while now. LOL NO ONE is making a more reckless statement of their own guilt than Conor and the UFC are. Neither Conor nor the UFC can even explain why it was such a "Scumbag Move", they can just rant.
Edit: I will also add that I am no Dana hater. I appreciate what he has done and what the UFC has become. I have spoken favorably of Dana and the UFC counter to the sentiment of many posts in this forum. This time, Dana and Conor's actions (and Conor's appearance) don't pass the sniff test.
