It's pretty simple, IMO. He can fight moving backwards well enough to deal with the bigger HWs, and his clinch game is the best I've seen in all of MMA. And the knees to the body from the clinch to me are easily one of the most stamina sapping moves in MMA. Also, he has some of the most versatile body attacks in mma. And his chin is God tier. With his body composition, he's almost a cheat code to the game. He has the perfect physique for fighting, and his style.
