Logic tells me khabib, bc that wrestling Is on another level. But I'm rooting for the upset. I think that if Justin can work that takedown defense of his, khabib is gonna be surprised by how hard he punches.
Against the fence, Khabib is more of an invincible. The only matter to see to is if Justin can somehow keep it in the middle and if he secures enough TD, those leg kicks are gonna be problem for the Eagle.
I really don't think Justin is gonna shoot for a takedown. I think he's gonna put the same game plan he used on Tony and keep it standing and out box khabib. Unless khabib can drag him down, I think khabib is gonna get outboxed.
