Football Fundamentals: Defensive Gap Discipline vs Formations, Pulling OL, and FBs
For a defense to be successful, they need to have "gap discipline". Being "gap sound" means having a defender in place to stop the offense on both sides of every blocker. By having a defender responsible for stuffing the play in each gap, the defense forms a wall at the LOS, and the offense has no way to be successful. It's the offense's goal to force the defense to lose gap discipline or be unable to cover the gap (by creating space). Each gap is an option for the ball carrier, and each open gap is potential for the offense to spring a play. In this post, we'll look at how gaps form against a few formations, and how lead blockers and pulling blockers change the numbers at the point of attack.
