Nah man here's the best kick in martial arts
But seriously this dude went into instant concussed mode the second Barboza's heel touched his face
Hell yeah good one spicer
On a serious note, that is about the most devastating kick in martial arts. A reverse hook to the head is hard to pull off if your opponent is paying attention, but that dude is going down if you land it with force! Heel to the head/temple - ouch!
