I was just watching HLN and saw a guy named Coleman (at the Junior Nationals) execute the following takedown.
He jumped straight up and over his opponent's left shoulder, came down (upside down) on his opponent's lower back, took him down, did a half twist while they were falling and ended up on top. He calls it the "flying squirrel".
They had a video of the takedown. Does anyone know how to find it? It was amazing!!
