Goal: Teach the DL to react quickly to the movement of the Offensive Lineman (OL)… Description: Set up 3 cones in a triangle about 10 yards apart. Two linemen face each other in the middle between two cones with a designated ball carrier at the third cone. The player facing the ball carrier is the defender, the other player the OL. The coach stands behind the DL signaling the direction and the snap count. On the command, the ball carrier runs in a straight line to the designated cone, while the OL blocks accordingly. The DL reacts to the movement of the OL, controls and escapes the OL making the tackle before the ball carrier reaches the cone. The defender's shoulders and hips stay square to the Line of Scrimmage (LOS), the feet stay moving and the hands/arms control and escape the OL. After the DL gets comfortable with the Drill, bring in 'real' OL and Running backs to increase intensity and speed… Equipment: 3 cones, 1 ball when run with offensive personnel."
