There are many teams that rely upon pull schemes to move the ball. These schemes create problems for defenses that try to play base gap control defense and read and react. Plays like the dart are troublesome for these schemes. Lets take a look at the couple of typical pull schemes that teams employ.


If you look closely a problem is created. The gap the pulling linemen is going throw gets split into two. This is similar to the problem that the ISO creates. This extra gap gives flexibility to the running back. Usually teams try to leverage their backers to deal with this. However this is not a viable option because the backers create a huge cutback lane, if they do this. Consider these two plays with the backers leveraging the puller.



There are six gaps and in this example we have 6 defenders to cover each of these gaps. So, whats the problem? The problem is that the offense moves where the gaps are on pull type plays.


Another way to defend this is have one of the linemen defeat the linemen at the point of attack. However, this is not the most reliable method year in and year out.
This was a long explanation of some simple plays, but I wanted to establish the problem the offense creates for the defense. The most effective way for countering an offensive concept is to look at the weakness of a particular scheme.
I was beating my head against the wall when I first started dealing with these plays, I tried to rearrange my fronts, stunt backers, and twist linemen. There would be some success, but I would leave myself open to other plays. It was a guessing game, but sooner or later I would get the defense out of position and give up a big play. I needed an effective counter that would remain sound against other plays.
What I realized was that both these plays relied on the guard base blocking the 3-technique one on one. I started slanting the 3-technique from B to A-Gap. This was a problem for guards to pick up because they did not expect a three technique to do this. If I had a tackle that had a problem with this technique, then I would cheat him back a step. This is not a hard technique to execute on defense, an it became my best defense for these types of plays. In one game the 3-tech had 6 tackles for a loss on this stunt.
The best part of it was, I was sound against everything else. The only change in the defensive scheme was that the backers had the B gaps.


This might seem like an overly simple adjustment. But I have found it to be one of the most effective ways to defend pull schemes. Teams have tried to counter it, but it more or less takes them out of pull schemes. Whenever you run a front with a 3 and a 1, the three technique draws a one on one block. This block is the weakness that the defense can take advantage of.
Even if you pull towards the 3 there is a one on one created. Consider this example.

This might have been too long an explanation for such a simple adjustment, but I found it helpful to understand it this way.
