Guard Recomposition Drill when Opponent Leg Drags (Drill)

Professor Frederico Silva shows a drill on how to recompose the guard when the opponent leg drags in an attempt to pass the guard. Frederico is playing guard and the opponent grips the leg and drags it to pass. Frederico reaches back to the hip with his foot and spins back to face the opponent. The opponent leg drags again and the sequence repeats.
