9. Kevin Lee vs. Gregor Gillespie
Lee is one of the most frustrating fighters in MMA. The Detroit native has all of the athletic gifts but often lacks the tactical nuance against high-level athletes. However, he has provided some superb moments. His most notable KO victory came against Gillespie when he landed a crushing head kick to win the fight. He crashed to the ground with a sickening thud.
After going back-and-forth for most of the round, Lee threw two punches with a rear-leg roundhouse close behind them. He connected with ‘The Gift’s’ temple, sending him to sleep immediately. Gillespie lay on the floor motionless for a few minutes before he finally came to his senses. As savage head kicks go, this one was brutal and terrifying in equal measure.
