With a single devastating overhand right, Alex Garcia knocks out Mike Pyle at UFC 207. This KO is neither luck nor a fluke: Pyle has made a fatal mistake.
It appears that Pyle is trying to strike with his rear right knee. This is Pyle’s critical error–he leads with a rear weapon. He extends his right hand as a counterbalance to wind up for the rear knee. Pyle is loading up for a strike that must travel all the way from his rear foot to its intended target. Pyle’s lead right hand is neither defensive to guard against the overhand right, nor offensive in the form of a jab to distract his opponent. The result is a long, slow attack without a preparatory offense (e.g., a jab, hand in the face, an attempt to tie up one of Garcia’s hands).
Pyle is literally walking straight into a brutal overhand right, and he’s out cold before he even hits the canvas. Be aware that if this is you on the street, the impact of your skull hitting the concrete will be even more injurious than the contact of his knuckles on your jaw. Some people KO’d on the street hit the pavement so hard while unconscious that they never wake up.
Delivered properly, the rear knee can annihilate an opponent, but you must set it up by combination. Throw a jab, then the rear straight. The rear hand can be used to grab after the straight punch, or is pulled back as the rear knee is thrown forward. The lead hand comes up to guard the head as the torso declines backward, which adds penetration to the rear knee while withdrawing the head as a target.
