Khabib isn't your average UFC step over. The dude commands a certain type of respect. How many fighters could say the shit he did to Dana White at UFC 205 without being mega stars like Conor and get away with it.
Yep. While Conor maybe the moneymaker and freakshow attraction. Khabib is literally an ambassador routinely doing showcases and touring all over Centrial-Asia and Russia, promoting both MMA and the UFC (and the Eagles MMA) brand.
If you follow his IG, he' all over the place commanding "respect" as you put it. Not to mention, his charity work: he was at an orphanage/disable center not long ago. He's also a big ambassador for Reebok in that part of the world, the store appearances get mobbed like crazy.
