Football Fundamentals: One-Gap 3-4 Defense
As teams begin to get faster, more spread out, and more pass heavy on offense, a way many defenses are counteracting this is by moving to a 3-4 defense. A 3-4 defense sacrifices some of the beef, at least in terms of numbers, at the LOS in favor of an extra LB (relative to a 4-3). However, not all 3-4 defenses are equal. From a high-level POV, there are two standard types of 3-4 defenses: One-Gap and Two-Gap. Both have different strengths and weaknesses and are generally played differently. In this article, we’re going to focus on the One-Gap 3-4 defense, it’s nomenclature, it’s strengths and weaknesses, the fundamentals of the front, and how it generally plays against a variety of offensive sets.
