Khabib beat Raphael dos anjos. dos anjos beat nate diaz. Nate diaz beat connor mcgreger. I realise mma math don't always work, but you can't do it the other way round because khabib is undefeated. Khabib beat the guy that beat the guy that beat connor, and that says alot, but styles make fights and if nothing else that's a big psychological advantage.
