How is the percentage of shots missed against him misleading? It's a representation of what happens when guys throw strikes at him standing.
He's not easy to hit. It doesn't matter if it's all based on the threat of the TD or if he doesn't look technically sound doing it. It's effective.
If Khabib's defense were as bad as you people are making out, he'd look like Corey Anderson or Pat Cummins. Those are two strong wrestlers who literally can't avoid a punch and constantly get hurt badly even when they're having success grappling their opponents.
Sorry, but if Khabib were as limited as you people are claiming, he would have suffered an embarrassing loss by now.
