He can manage to prolong the fight. He is definitely one of the most durable fighters in the UFC even at his age. The only was I see Chimaev stopping him is by submission.

Well, Nate still has the arsenal to upset anyone. The question here is if he's motivated enough to win and I'm not sure about that now. In his fight with Edwards, he had a chance to finish him but I was surprised he paused and taunted which gave Leon few seconds. In case he hurts Chimaev, I think he'll do the same as the previous fight.
