I think anyone counting Conor or Khabib out is delusional. Khabib could very well get face-planted, and Conor could very well get mauled for a few rounds.
I do, however, think the discrepancy in skill is greater on the feet than it is on the ground. I'm not saying Khabib isn't a grappling monster, but I do think Conor is much more of a killer in his specialty. Khabib's fights are painful to watch because he's hitting the other guy while controlling him and there's nothing the other guy can do to stop him. Conor's fights, you have rewind and watch in slow-mo just to see what happened.
I've thought about this fight a lot. I still think it's 50/50 but I'm leaning a little toward Conor because Conor's tdd is underrated due to his sense of range, timing, and his footwork.
