What works so well for Khabib is that he has a sense of urgency on his feet. He strikes solely to disrupt his opponent, drive him back toward the fence and take his opponent down.
Contrast this with an exaggerated polar opposite in Nate Diaz who, when his opponent runs away, simply walks after him instead of hunting him down quickly.
Khabib gobbles up the space between himself and his opponent by running after him with a raised guard, and jab. He’s still very open to side kicks, teeps and counters upstairs but his bumrush style makes it hard to be planted and or accurate.
I personally think Conor has a good chance of beating Khabib since Conor uses kicks to disrupt rhythm and distance long enough to time a well placed left counter shot. Edson threw low kicks which doesn’t prevent closing of the distance well.
Lastly, I think a lot of Khabib’s opponents respect him too much, that combined with a good chin makes all his opponents fight scared. That said, the credit must be given to Khabib for at least fighting in such a way that emphasizes urgency and suffocating pressure while keeping his right glove planted firmly against his chin - Obvious, but smart move.
A fight between Conor and Khabib would be fun to watch and I give Khabib a 65% chance of winning, which is much less than most people think.
I can’t stand the UFC’s politics regarding Conor but truth be told, Conor’s timing, accuracy and left hand causes people tons of problems, regardless of his crap cardio and limited arsenal of skills.
