Sokoudjou's Fists Of Death?
Playback his last two KO's.
Either Trigg or his co-host mentioned this in 34:
When Sokou hit Arona with the game-over uppercut, he was almost totally off balance. There was no opportunity to put any lower body in his hit.
Rewind to the little Nog fight. His KO was not 100% deliberate. In fact, if you ask me, it was a reactionary punch. I don't think Sokou even thought it would connect, rather using it for a keep-away.
"This guy must have some heavy hands". Anyone ever seen anything like this before? I sure haven't.
