Introduction: Defensive football terminology can be confusing to new players and fans, but it’s important to understand the key terms used by coaches and players to communicate on the field. In this lesson, we’ll cover some of the most common defensive football terms and what they mean.

  1. Types of Defense: There are two main types of defensive schemes in football: the 4-3 and the 3-4 defense. The 4-3 defense uses four down linemen and three linebackers, while the 3-4 defense uses three down linemen and four linebackers. The choice of which defense to use depends on the strengths of the players on the team and the opponent’s offensive tendencies.

  2. Defensive Line: The defensive line is made up of the players who line up opposite the offensive line. The defensive line’s primary job is to stop the running game and pressure the quarterback on passing plays. The defensive line is made up of defensive ends and defensive tackles.

  3. Linebackers: Linebackers are responsible for stopping the run, covering receivers, and rushing the quarterback. They line up behind the defensive line and are typically the most versatile players on defense. There are three types of linebackers: strongside (SAM), middle (MIKE), and weakside (WILL).

  4. Defensive Backs: Defensive backs, also known as the secondary, are responsible for covering receivers and preventing big plays in the passing game. There are two types of defensive backs: cornerbacks and safeties. Cornerbacks cover the outside receivers, while safeties cover the middle of the field and help defend against the run.

  5. Blitz: A blitz is when a defense sends extra players to rush the quarterback. This can be done by sending linebackers, defensive backs, or even the defensive line. The goal of a blitz is to disrupt the quarterback’s timing and force him to make a mistake.

Conclusion: Understanding the basic terminology of defensive football is important for anyone who wants to understand the game. By understanding the different defensive schemes, the roles of the players on the defensive line, linebackers, and defensive backs, and what a blitz is, you’ll be well on your way to becoming a knowledgeable football fan.
