He forced an entire round of standup by defending all 3/3 TDs and outstruck Khabib 44-17, being the first guy to ever officially win a round off of him. He successfully nullified Khabib on the ground for the entirety of round 1 and huge portions of the rest of the fight while other guys got 30-24'd. His only truly bad moment was round 2 where he got knocked down and pounded on for most of the round, but everybody just ignores he successfully worked his way back to his feet anyways with like a minute left before the round ended and Khabib couldn't get him back down until round 4.
Anybody who came out of that fight thinking that Conor absolutely couldn't win is delusional. It's not an easy win for him by any means, but he showed he can outstrike Khabib when he can force Khabib to stay standing by successfully defending his takedowns, that he can stem Khabib's ground game when taken down, and he can get back to his feet.
Again, guys like Barboza were down 30-24 after 3 rounds. THAT is an example of someone being extremely unlikely to be able to win. Conor was down 29-27. That literally means he's winning portions of the fight, and not getting blown out. How can you say Conor has no chance? It not being easy is not the same thing as it being impossible. He just needs to do what he was doing successfully more. Or just KO him.
