Umm. Yes. Would they beat him in an MMA fight? No, but they are clearly better grapplers/wrestlers. This is like someone saying McGregor has better hands than Mayweather because he would beat him in an MMA fight.
My man you are clearly so wrong on this. The whole point is that Khabib is the best wrestler in the UFC ever. Not the most accomplished, not the best wrestler ever, but simply the best wrestler ever to grace the Octagon under the set rules. No one will even attempt to offer a counterpoint to that because it’s as unanimous as it gets with the opinions of people who know way more than you and I.
