Khamzat dug deep vs Burns and Usman, where he faced adversity and still came out on top, against vastly more experienced opponents. Also, against 2 tough stylistic match-ups.Gassed DDP is the best DDP lol. Have you been watching his career? One of these guys has shown a great ability to dig deep while gassed, and it isn't khamzat.
He showed that he could still take down Burns after getting knocked down, increase his output in round 3 to win the fight on the feet. He threw 94 punches in round 3, and Burns looked more gassed.
Against Usman he was sick + injured his hand at the end of round 1, yet still took him down in rounds 2 and 3 to be able to win a decision.
Let's not pretend like either of them are helpless while gassed/tired.
