Khabib is great because he has extremely high fighting IQ, perfect technique, and never ending cardio.
He has one weakness, the same loyalty DC has: loyalty. He will never abandon deadweight to pick up new, better friends. That's a weakness that can be exploited. Someone that's willing to abandon deadweight and take on all new, better people to replace them can use those new, better people to develop and surpass Khabib. Unfortunately: Conor has the same weakness of loyalty as Khabib does. So, Conor will never beat Khabib.
