All Secondary Drills:
Since we consider our ends as part of our defensive secondary, as I explained previously, they will take part in all of the drills explained and illustrated in [Figures 120-128], if feasible.
DRILLS FOR THE DEFENSIVE INTERIOR LINEMEN
The following drills are used to teach individual and team techniques to the interior linemen:
Butt Ball Drill (8-10 men):
An offensive man is given a football and told to run a straight line laterally back and forth, carrying the ball on the side he is moving toward. The defensive man must be in a good football position moving back and forth with the offensive man, butting the football with his forehead. He bounces back and forth and keeps butting the football trying to knock it out of the ball carrier’s arm. The tackler’s head should be up and his back straight. (The Butt Ball Drill is not illustrated by diagram.)
4-on-1 Drill (6-8 men):
[Figure 131] illustrates four offensive blockers playing one defensive man. The coach stands behind the defensive player, and indicates by hand signal the starting count and the blocking assignments of the offensive men. The defensive man must react to the various blocks—double team, wedge, trap, etc., and fights pressure.
