This numbering system is referred to as “defensive line techniques.” In a sense, the name is a little bit misleading because the numbering system instructs a defensive lineman where he is to line up in relation to the opposing offensive lineman. It is not a step-by-step procedure on the type of blocks to use or what he should “key” off of in different downs and distances.
So why should you, the average fan, learn this system? Well once you understand it, you can learn a lot about how the offensive and defensive linemen are going to attack each other.
