"Controversial" decision aside...dude just shut all the haters up (myself included) that said he wouldn't be able to compete at the highest level against the best fighters in his weight class while he's not cheating.
Well, we still don't know "if he wasn't cheating"... that usually comes in the weeks after the fight
But assuming he was clean, it does not answer many questions IMO.
this was an atypical fight. He got tagged, hurt, injured.
So you don't know what/how he would be otherwise.
But beyond the judging controversy (if he did win or not), he did push through all of it and never gave up, which is a good sign.
He beat a top opponent, and I do think he is/has always been a top talent in the division.
Moreover, imagine how he'd be without all those things going against him?
The question is: can he continue doing it without the "help"? Or will he be tempted/pressured to do it again to stay at the top?
