The 4-2-5 Defense: A High School Coach’s Perspective

 

The 4-2-5 Defense

This blog is apart of a defensive scheme series where each blog I break down different defenses and explain how the defense works, the structure and alignment, strengths, weaknesses, and when to use it. This is the fourth blog in the defensive scheme breakdown series and below are the previous blogs:

To start things off, I want to be clear that I am not saying the 4-2-5 defense is better or worse than other defenses. The best way to put it is, it is just a different strategy a coach can choose to play football. As I have said in the other blogs, a coach must choose their defense based on what best fit their personnels. The best personnel for the 4-2-5 defense are teams who have a good mix of players: big players AND speed players. The defense has become extremely popular, especially at the high school and college levels, because of pass heavy teams. At the high school level, if you have a good defensive back who is really good in space at tackling, then the 4-2-5 could be a great choice for you. The 4-2-5 defense has four players on the defensive line, two linebackers, and five defensive backs in the secondary. From a coach’s perspective, the best thing about the 4-2-5 defense is the simplicity and versatility. It is a great hybrid and mix of two great defensive schemes: the 4-3 and 3-3-5. The worst thing about the defense is since it takes a linebacker way, it can struggle against power run teams if you do not have six guys in the box that are strong, big, and dominant. 

How the 4-2-5 Defense Works

The 4-2-5 defense is built around speed, size, and simplicity. With four defensive linemen, the defense can consistently generates pressure without having the need of sending a blitz, keeping more players in coverage. This is one of the main advantages of the 4-2-5 defense. Behind them, the two linebackers have the same responsibilities as other defenses: fitting the run and defending short passes. Similar to the 3-3-5, behind the linebackers there are five defensive backs. They are primarily responsible for defending the pass and rallying to the run. The nickel (the fifth DB, who is typically a LB/DB hybrid), needs to be fast enough to play the pass and strong enough to stop the run. 

The Structure and Alignment

• Four Defensive Linemen: Responsible for controlling the line of scrimmage and getting pressure on the quarterback.
• Two Linebackers: Primarily responsible for fitting the run and defending short passes.
• Five Defensive Backs: 
• Two corners and two safeties who are primarily responsible for defending the pass but can help out in the run game when needed. 
• One nickel or sometimes called "rover", who is a hybrid that primarily defends the pass while also providing some run support.

The 4-2-5 is a great defense if you have the guys because it is a hybrid defense that is best fit to defend the pass while also having a good ability to stopping the run. Below is a very common look against the doubles formation.

Honestly, a 4-2-5 is just a different version of the 4-3, one specifically designed for defending the pass.

Strengths of the 4-2-5 Defense

1. Speed. One of the biggest strengths of the 4-2-5 defense is the extra speed. What it lacks in size is made up for with the speed and athleticism. This makes it very effective against all types of offenses.

2. Great against the pass. With an extra defensive back, the defense matches up well in the passing game against other teams.

3. Flexibility. If you have a very athletic nickel defender who can defend the pass AND RUN, the 4-2-5 allows defenses to adjust easily without changing personnel. This makes it easier to defend different offensive formations.

Weaknesses of the 4-2-5 Defense

1. Only two linebackers. With only two linebackers, it can be difficult to defend power run teams. The linebackers must be able to make tackles and play physical. This is why many teams will sub out the nickel for another linebacker to give a 4-3 look.

2. Personnel. The 4-2-5 requires a great front six, who must be strong and dominant to stop the run without relying on help. It is also good to have athletic defensive backs who can tackle and play in space.

When to Use the 4-2-5 Defense

The 4-2-5 defense is a great choice for teams who have a good mixture of big and small kids. The defense works best if you have a few big guys who take up space and very physical linebackers and safeties. It works best when teams have athletic linebackers and defensive backs who can tackle in space. At the high school level, the 4-2-5 defense is becoming more popular because many offenses are throwing the ball more but can struggle against teams who run the ball. So, my recommendation is if you are playing a pass heavy team, use the 4-2-5 but if you are playing a run heavy team, adapt into a 4-3.

The 3-3-5 Defense: A High School Coach’s Perspective

The 3-3-5 Defense

This blog is apart of a defensive scheme series where each blog I break down different defenses and explain how the defense works, the structure and alignment, strengths, weaknesses, and when to use it. This is the third defensive scheme breakdown, click here to find the 4-3 defensive breakdown and click here for the 3-4 defensive breakdown. 

To start things off, I want to be clear that I am not saying the 3-3-5 defense is better than other defenses. Simply, it is just a different way and strategy to play football. As I have said in the other blogs, a coach must choose their defense based on their personnel. The best personnel for the 3-3-5 defense are teams who do not have a lot of size, but have a lot of speed. In high school, the defense has became very popular in recent years due to a lot of pass heavy offenses. The 3-3-5 defense has three players on the defensive line, three linebackers, and five defensive backs in the secondary. From a coach’s perspective, the best thing about the 3-3-5 defense is the speed and versatility. I believe if it is ran correctly, it not only stops the pass, but also puts defenses in positions to shut down the run. The worst thing about the defense is it can struggle against power run teams and getting pressure if players are not disciplined, well-coached, and physical.

How the 3-3-5 Defense Works

The 3-3-5 defense is built around speed, versatility, and confusion. This defense does a great job at allowing defenses to move players around and disguise where pressure is coming from. My favorite part about the defense is how it can go from a three defensive linemen to five or three linebackers to five in a snap of a finger. Same as the 3-4 defense, the 3-3-5 can send pressure from the left, right, or both. In this defense, your two extra safeties need to be studs and are typically the best athletes on the team. They need to be fast enough to play the pass, strong enough to take on kick out blocks, and versatile enough to stop the run. Now, for the big guys on the line, their job is to control the line of scrimmage and really just get in the way of the offensive line. Doing so, they will keep the linebackers clean so they can make plays. Behind them, the three linebackers read and react. They must be able to fit the run, rush the quarterback, and drop into coverage. The other three defensive backs are responsible for defending the pass and serves as the last line of defense.

The Structure and Alignment

• Three Defensive Linemen: Responsible for controlling the line of scrimmage and forcing double teams.
• Three Inside Linebackers: Primarily responsible for fitting the run and defending short passes.
• Five Defensive Backs: 
• Two corners and one free safety who are primarily responsible for defending the pass but can help out in the run game when needed. 
• Two safeties that are hybrids who, depending on the play can primarily provide run support or primarily provide pass support.

The 3-3-5 defense can line up in so many ways, but requires strong communication and discipline. Which is definitely why I personally love the defense. Below are three different common base alignments I use to the doubles formation.

Depending on the situation, you can have your safeties deep or close to the line of scrimmage. It is easy to confuse an offense when you give them so many different looks. 

Strengths of the 3-3-5 Defense

1. Speed. One of the biggest strengths of the 3-3-5 defense is the extra speed. What it lacks in size is made up for with the speed and athleticism. This makes it very effective against all types of offenses.

2. Confusing the opponent. The 3-3-5 defense allows defenses to move players around and disguise where pressure is coming from. This makes it difficult for the offense to know who is rushing and who is dropping into coverage, making it tough for the offense to execute their assignment.

3. Great at stopping the run and pass. Depending on the situation, a good coach can put their players in a great position to stop what they are expecting. If it is a passing situation, the coach can easily put the defense in a great position to stop it. If it is a running situation, the coach can easily put the defense in a great position to stop it. 

Weaknesses of the 3-3-5 Defense

1. Complexity. The 3-3-5 puts more pressure on the coach and if you are a coach who hates pressure, this defense is not for you. You need to be a good coach to run this defense correctly. The 3-3-5 defense makes a coach have to think in every situation so they can put the team in the correct position. 

2. Physicality. Because the defense has smaller players on the field, it usually lacks size in the box. If players are not disciplined and physical, teams can take advantage by running the ball.

3. Communication. The 3-3-5 defense requires strong communication between coaches and players. This is because every player is constantly moving around. If everyone is not on the same page, it can lead to big plays for the offense.

When to Use the 3-3-5 Defense

The 3-3-5 defense is a great choice for teams who do not have a lot of big sized kids but have a lot of fast kids. The defense works best if you have a few big guys who take up space and very physical linebackers and safeties. At the high school level, the 3-3-5 defense can be very effective but at lower levels it can be difficult to teach and may not be a good defense to use because teams are usually run heavy at that age.
