The defensive line position is one of the grittiest positions in football. It requires quick reactions, strong hands, and the ability to shed offensive linemen.

This article will show you how to play defensive line in football and what you need to be a great defensive lineman.

Defensive Lineman In Football

The defensive line controls the line of scrimmage. It is up to these players to make sure the offense can’t effectively run the football.

If a team has a weak defensive line, there’s a good chance that the offense can run whatever play they want.

Defensive linemen must possess tough qualities, as they contact bigger offensive linemen every play.

Before you decide to play defensive line, there are a few qualities that every defensive lineman should have.

Defensive Line Positions

The defensive line is broken up into positions. Each position has a certain body type and skill set necessary to excel at their position.

Defensive Tackle

The first position is the defensive tackle. This is the 2 interior linemen in an even front and the one interior lineman in an odd front.

It’s common that the most inside defensive tackle is called the nose tackle, or nose guard. This player is often the heaviest player on the field, as they are responsible for anchoring the A gaps on defense.

Nose tackle and defensive tackle positions

The defensive tackle is someone who needs to be quick enough to the guard pulling or attacking him. They should be quick with their hands and strong enough to fight a double team from offensive linemen.

Defensive Ends

Defensive Ends In Football

The next position is the defensive end position. Defensive ends are responsible for containing the run and making sure nothing gets to the outside. On passing plays, the defensive end is in charge of trying to beat the offensive tackle and get to the quarterback for a sack.

In an even front, they are typically lined up on the outside of the offensive tackle. In an odd front (three defensive linemen), they are lined head-up with the offensive tackle or on the inside shoulder. It all depends on the coach and how many defensive formations he wants to use.

Their job is to make sure that the team’s primary ball carrier on offense doesn’t get to the outside, into space on running plays.

Defensive ends can choose to be in a three-point stance or a two-point stance on the line of scrimmage.

Defensive Lineman Qualities

Toughness

The first quality of a defensive lineman is their toughness. When we say tough, we mean both mentally and physically demanding.

Mental toughness is being consistently blocked by an offensive lineman, but still giving maximum effort.

Physical toughness is being able to hold your ground against single-man blocks, as well as double-team blocks.

This means you may have to fight off two offensive players simultaneously while maintaining your gap fit responsibility.

Endurance

The second quality of an excellent defensive lineman is good stamina and endurance. All it takes is one play for the other team to score in football.

If you’re someone who tires easily, playing the defensive line may not be the position for you.

That way, defensive linemen need to play at 100% every play; they can force the offense not to run the football or not run it to your side.

If you’re not in shape, the offensive coordinator on the other team will see that and continuously run the football to your side.

Relentless Effort

The last characteristic of a good defensive lineman is a relentless attitude. This means whenever the ball goes, you’re running full speed to it.

Defensive players who take plays off or jog to the ball carrier are only hurting their team.

Defensive linemen should run as fast as they can to the football every play.

This is why being in shape is crucial, as defensive players need to swarm the ball carrier so he doesn’t gain yards.

How To Play Defensive Line In Football

Now that you know the mentality and qualities a defensive lineman should possess, let’s talk about playing defensive line in football.

Stance

A defensive lineman’s first and most important learning is a proper stance. The stance helps propel the defensive lineman toward the offensive lineman at maximum power.

Remember, speed and power are the two crucial elements when playing as a defensive lineman. You’ll want to maximize both efforts when getting into your stance.

First, start with your feet shoulder-width apart from each other.

Next, move your power foot back, 6 inches behind your opposite heel.

From here, get into a squat, so your elbows are touching your knees.

Last, reach out with the same hand, on the same side as your power foot (the foot that is back). This should get you into a stance where you are ready to explode off and play football.

Start

Now that we’ve taught you the proper stance, it’s time to practice your start. Your start, also known as the “get-off,” moves toward the line of scrimmage when the ball is snapped.

Your stance and start are essential to getting past an offensive lineman as a defensive lineman.

When the ball is snapped, fire off to the offensive lineman and make contact with your hands first. You want to make contact with your hands first to get separation from the offensive lineman.

If you bury your head or hit with your shoulder pads, you will have no vision of the ball carrier. Our job as a defensive lineman is to disengage the offensive player and make a tackle in the backfield.

Run Fits

Run fits are responsibilities that each defensive lineman has in the run game.

Each play will be responsible for a gap (or sometimes 2). This means they must punch the offensive player and protect their gap if the running back or quarterback tries to run through it.

To understand run fits, you must first understand gaps and techniques. We recommend you check out this article, which explains everything you need to know about gaps and techniques.

Pass Rush Moves

Pass rush moves are the key element when playing the defensive line. When the opposing quarterback drops back to pass, it’s essential to get to him as fast as possible.

Our goal as a defensive lineman is to disrupt the quarterback. This means making him feel uncomfortable and making a wrong decision.

Constant defensive pressure on the quarterback will cause him to make poor decisions, which will benefit your team.

A pass rush move is a movement that you do to get past the offensive lineman trying to block you. We recommend checking out this article for a complete list of pass rush moves.
