Not that impressed???? How can you not be that impressed by someone taking there gi and wrapping it around the others neck. It's not like they fell like that, he set it up and held Mayhem broken down long enough to do it. I've rolled with Mayhem and he is a beast. Holding him in guard with broken posture was made to look easy, Mayhem is a strong dude, it wasn't easy.
I am not familiar with that gi choke, but it looks like a tough one to do to anyone not to mention a fresh opponent with no shirt on.
Great video.
