Why else wouldn’t Khabib go and get a 4th UFC lightweight defence?? It’s because he has the most utmost respect for the real lightweight goat BJ Penn!!! And I think deep down inside of khabib, he knows a motivated BJ Penn would finish him within 3. I can not understand any other reason. And neither should anyone else. Khabib and his dad, mother too- knew this. And they wanted to pay their own respect to the real lightweight goat. Now this retirement is one thing I can admire about Khabib, one thing I can not is if he chooses to return. Because I can’t help but think this.
