Texas A&M receivers coach David Beaty takes 12thManTV through a drill called "the box drill" in the film room with some very good footage from a recent practice, and provides some excellent coaching points.
Beaty says that Kevin Sumlin and the staff have really put a renewed emphasis on making every off season drill they do very competitive, with a definitive winner and loser.
The box drill works release moves, with a focus on getting the defensive back in a trail position. The object is to stay inside of the marked 5 yard area and touch the coach once the receiver gets stacked back on top of his route.
Very good drill and good coaching points in the video below.
