Watch as Coach Glenn Schumann explains and shows practice video of this shoulder reduction LB pass rush drill. The drill simulates a LB working the A or B gaps and continuing to gain ground. The coach is the QB and can move the aim point for the backer and every tackle will be an open field tackle. The LB is working on transitioning from a long stride to a short stride then coming to balance. Coach shows game clips of this technique with further explanations.
