Never thought I would say this...but I think Conor has value at +odds.
Khabib's only great win is against RDA, and wrestlers always smash BJJ guys. Colby Covington also beat RDA, and I wouldn't bet him against Conor in a million years.
His wins vs Barboza, MJ, and Iaquinta were all comfortable, but Conor is light years better than any of those guys. He has also beat 5 guys who are better than all 3-- Alvarez, Aldo, Poirier, Mendes, and Holloway.
Conor will spend some time on his back, but he doesn't need a huge time window to finish. Only needed 30 seconds at the end of round 2 to KO Mendes. And Khabib is such a non-finisher, Conor should have plenty of windows to KO over course of 5 round fight.
Also Khabib's takedowns not the same as Mendes, who is much more explosive. Just bc Mendes got there doesn't mean Khabib will. Not that Eddie's wrestling is nearly on Khabib's level, but Conor's takedown D was excellent in that fight.
Only concern is that Conor is always drunk or coked up lately, but he is only 30 and I doubt he is completely washed. Maybe he's a bit worse than before, but he's the better athlete, 4" better reach, better finisher, has a better hit list. Those are a lot of favorable points for a +140 dog.
