Mount to Back Control when Opponent Turns to Rear Naked Choke (Fundamentals)

Professor Lucas Lepri demonstrates how to get the rear naked choke starting from the mount position. Lucas has the mount position on the opponent. The opponent tries to escape by turning to one side. Lucas lets the opponent turn by relieving some pressure. As soon as he can, Lucas goes for the back and establishes the seat belt grips. With the opponent now in the turtle position, Lucas turns him forwards the arm that is over the opponent's shoulder and finishes taking the back. From the back control, Lucas nos goes for the rear naked choke and submits the opponent.
