The best possible scenario for Mcgregor, is that Tony beats Khabib. There is no way that Conor would ever beat Khabib even though he is actually bigger than him. Cucuy has a decent chance at catching Khabib in a tricky choke. And as we know cucuy has been dropped many times by hits to the head. Cucuy winning the title is the only way McNuggets can be champ again, he needs a chinny/ hitable opponent to shine!!!
tony vs conor is a tricky fight, conor can legit catch him in the early rounds, but every one does and tony doesn't care because of his incredible recovery, so conor would have to one shot KO him like the aldo fight. But if the fights goes on after the 2nd round, we will witness one of the worst beating in a UFC main event I believe. Conor's image will never be the same if he stays in the octagon with tony for 25 minutes.
