As much as I hate Khamzat because he's a pullout artist, he strikes me as the kind of guy who is almost unbeatable if he makes it to the octagon healthy.
This guy seems terrified of losing, and so he cuts maximum weight and overtrains like crazy. That in turn means he pulls out of a lot of fights due to bad weight cuts and/or injuries (because you simply can't train like him without getting injuries).
But when he does make it to the octagon without injury and makes weight, he's unstoppable. That's why people should never agree to fight him a 2nd time after he pulls out of a fight. You give him one chance, and you tell the UFC if he doesn't show up, you'll never fight him again.
That way you make Khamzat beat himself by showing up injured, or with a bad weight cut. Eventually he will be forced to do that, and then he will lose. And once he loses, his entire career will unravel.
