Khamzat looked mentally broken despite winning a close decision over Burns, he realized that he's not an invincible Khabib 2.0 as many saw him before. He couldn't run through Burns despite making fun of his size and ability before the fight.
Nate Diaz is extremely hard to finish, cardio for days (Chimmy was huffing and Puffing by round 2), and good BJJ (Khamzat wasn't confident enough to entertain grappling with Burns, so we know it's a weakness)
Nate Diaz by Double Finger Triangle
Nate got absolutely owned by Masvidal. I don't see him faring better with Khamzat
