My reaction was despite winning that it was the first time he faced the wrestler problem and he failed the test. After that he never faced another wrestler until Khabib, where he failed again. I think Mendes with a full camp wins that fight, Chad was never known to gas and it almost certainly had to do with taking a fight on 2 weeks notice. (Yes im aware, Conor kicked the body).
Chad was an amazing talent, dude gets no respect. All the fans these days don't understand fighters fall out of their primes.
