Usually in these kind of fights I will take the guy with finishing ability, and that is definitely Conor.
I think the first one who can impose their will onto their opponent, wins the fight.
Right off the hop. Khabib's best chance, is to aggressively take McGregor down.
He gets kicked, or punched hard, forcing him to backtrack, and tentative on his takedowns from then on, and that's the fight right there. McGregor has an iron chin, so a punch from Khabib is highly unlikely to crack it.
He manages to pressure McGregor into biting into one of his faints, where he then goes for your legs, and mauls him, and just man handles him from the start--the fight is over then and there, the longer this goes on.
