In American football, defense is not only about strength and speed. It is also about how players are positioned on the field before the play starts. Coaches use different alignments to stop the offense from running or passing the ball.
One important term used in football strategy and in video games like Madden NFL is “Under 4 Tech.” This term describes a specific defensive alignment used by many teams.
To understand what Under 4 Tech means, we need to learn two basic ideas:
-
Defensive technique numbers
-
The Under defensive front
This guide explains these ideas in simple and easy language.
Understanding Defensive Technique Numbers
In football, defensive players line up across from offensive players. Coaches use technique numbers to describe exactly where a defender stands.
A technique number tells the defender:
-
Which offensive player they face
-
Where they stand on the line
-
Which area of the field they must defend
Common Defensive Techniques
Below is a table showing some common technique numbers.
| Technique | Where the Defender Lines Up | Description |
|---|---|---|
| 0-Tech | On the center | Directly in front of the center |
| 1-Tech | Next to the center | On the shoulder of the center |
| 3-Tech | Outside of the guard | Between the guard and tackle |
| 4-Tech | On the tackle | Directly in front of the offensive tackle |
| 4i-Tech | Inside of the tackle | Inside shoulder of the tackle |
| 5-Tech | Outside of the tackle | Outside shoulder of the tackle |
What Is 4-Tech?
A 4-technique means the defender lines up directly in front of the offensive tackle.
This position is often used by defensive ends in a 3–4 defense.
What Does “Under” Mean in Defense?
The word “Under” describes how the defensive line shifts based on the offense.
Most offenses have a strong side. This is usually the side where the tight end lines up because that side has more blockers.
An Under front means the defensive line shifts away from the strong side.
This helps the defense control running lanes and balance the defensive line.
Key Features of an Under Front
An Under front usually includes:
-
Defensive line shifted away from the tight end
-
One defensive tackle in a 3-tech position
-
A nose tackle near the center
-
Linebackers ready to fill running gaps
Example of an Under Front
| Defensive Player | Usual Technique | Main Job |
|---|---|---|
| Nose Tackle | 0 or 1-Tech | Stop inside runs |
| Defensive Tackle | 3-Tech | Attack gaps |
| Defensive End | 4 or 5-Tech | Control offensive tackle |
| Linebackers | Different spots | Stop runners and cover passes |
This setup helps the defense stop running plays more easily.
What Is Under 4 Tech?
Under 4 Tech is a defensive alignment that combines two ideas:
-
The Under defensive front
-
A defensive lineman positioned in a 4-technique
This means a defender lines up directly in front of the offensive tackle while the defensive line is shifted in an Under formation.
This alignment is often used in 3–4 defensive systems.

Typical Under 4 Tech Alignment
Below is a simple example of how players may line up.
| Defensive Player | Alignment | Role |
|---|---|---|

| Opposite End | 5-Tech | Protect the outside edge |
| Inside Linebackers | Behind the line | Stop inside runs |
| Outside Linebackers | On the edges | Rush the quarterback |
Each player has a specific gap or area to defend.
Under 4 Tech in Madden NFL
Many people see the term Under 4 Tech in the Madden NFL video game.
In Madden, defensive formations are named based on how the defensive players line up. One of these formations is called 3–4 Under 4 Tech.
Several team playbooks in Madden include this formation.
Teams That Use It in Madden Playbooks

|---|---|
| Philadelphia Eagles | 3–4 defense |
| Atlanta Falcons | 3–4 defense |
| Los Angeles Rams | Hybrid defense |

Players can choose many different defensive plays from this formation.

Zone coverage plays
-
Blitz plays
These plays combine defensive positioning with pass coverage strategies.
Purpose of the Under 4 Tech Alignment
The Under 4 Tech alignment helps defenses stop both running plays and passing plays.
Run Defense
The formation is strong against the run because defenders control important gaps.
Run Defense Benefits
-
Stops inside running plays
-
Forces runners toward linebackers
-
Helps defenders control blockers
| Feature | Benefit |
|---|---|
| 4-Tech alignment | Controls the offensive tackle |

Because of these challenges, defenders must stay focused and disciplined.
Difference Between 4 Tech, 4i Tech, and 5 Tech
These technique numbers are similar but have different alignments.
| Technique | Position | Meaning |
|---|---|---|
| 4-Tech | Head-up on tackle | Directly in front of tackle |
| 4i-Tech | Inside shoulder of tackle | Between guard and tackle |
| 5-Tech | Outside shoulder of tackle | Outside edge of tackle |
Small changes in alignment can change how defenders attack the play.
Why Defensive Techniques Are Important
Defensive techniques help teams organize their defense. When every player knows where to line up, the defense becomes stronger and more effective.
Benefits of Using Technique Alignments
-
Helps defenders understand their job
-
Improves teamwork on the defensive line
-
Makes it easier to stop running plays
-
Allows coaches to design better defensive strategies
These techniques are used at all levels of football, from high school to the NFL.
Conclusion
Under 4 Tech is a defensive alignment used in football where a defender lines up in a 4-technique position within an Under defensive front. This formation shifts the defensive line away from the offense’s strong side while placing a defender directly across from the offensive tackle.
The formation helps defenses control running lanes, pressure the quarterback, and maintain strong gap discipline. It is commonly used in 3–4 defensive systems and also appears in Madden NFL playbooks.
By understanding concepts like Under 4 Tech, football fans and players can better understand how defenses work and why teams choose certain formations to stop the offense.
