One of the most critical and versatile positions on the defensive side of the game is the linebacker.
Linebackers play a vital role in stopping the opposing team’s offense and are often considered the backbone of the defense.
They are responsible for stopping the opposing team’s running plays, covering receivers in pass plays, and even rushing the quarterback in some situations.
Below we look at the different types of linebackers, their roles, and the specific responsibilities associated with each position.
The Different Types of Linebackers
There are several types of linebackers in football, each with its own set of responsibilities.
The main types of linebackers include:
- Inside Linebacker (ILB)
- Outside Linebacker (OLB)
- Strongside Linebacker (Sam)
- Middle Linebacker (Mike)
- Weakside Linebacker (Will)
Inside Linebacker (ILB)
The inside linebacker, also known as the ILB, is typically positioned in the middle of the defense, behind the defensive line.
They are responsible for stopping the run, covering short passes, and providing support to the defensive line.
The ILB needs to have excellent tackling skills and be able to read the opposing team’s offensive plays quickly.
Outside Linebacker (OLB)
The outside linebacker, or OLB, is positioned on the outer edges of the defensive formation.
They have a more versatile role compared to the ILB, as they are responsible for both stopping the run and defending against pass plays.
OLBs need to be agile, fast, and have good coverage skills to effectively defend against both the run and the pass.
Strongside Linebacker (Sam)
The strongside linebacker, often referred to as the Sam linebacker, lines up on the side of the offensive formation with the most players.
Their primary responsibility is to set the edge and prevent runs to their side of the field.
Sam linebackers are typically larger and more physical, as they often have to take on offensive linemen and tight ends.
Middle Linebacker (Mike)
The middle linebacker, also known as the Mike linebacker, is positioned in the middle of the defense, behind the defensive line.
They are often considered the leader of the defense and are responsible for making play calls, adjusting the defensive formation, and reading the opposing team’s offense.
Mikes need to have exceptional football IQ, strong communication skills, and the ability to quickly react to changing situations.
Weakside Linebacker (Will)
The weakside linebacker, commonly referred to as the Will linebacker, lines up on the side of the offensive formation with fewer players.
Their primary responsibility is to cover the weak side of the field and provide support in pass coverage.
Will linebackers are typically more athletic and excel in coverage skills, as they often have to defend against running backs and tight ends in pass plays.

Responsibilities of Linebackers
Linebackers have a wide range of responsibilities on the football field.
Some of their key responsibilities include:
- Stopping the run: Linebackers are responsible for filling gaps, shedding blocks, and tackling ball carriers to prevent them from gaining significant yardage.
- Pass coverage: Linebackers need to be able to cover tight ends, running backs, and sometimes even wide receivers in pass plays. They must read the quarterback’s intentions and react accordingly.
- Blitzing: Linebackers are often utilized as pass rushers, where they blitz the quarterback to disrupt the opposing team’s passing game. This requires speed, agility, and the ability to navigate through offensive linemen.
- Setting the edge: Certain linebackers, such as the Sam linebacker, have the responsibility of setting the edge in run defense. This means they need to maintain outside containment and force ball carriers back inside towards their teammates.
- Play recognition: Linebackers must quickly analyze the opposing team’s offensive formation, read the play, and react accordingly. This involves studying film, understanding tendencies, and making split-second decisions.
- Leadership: Middle linebackers, in particular, are often responsible for making play calls, adjusting the defense based on the offensive formation, and communicating with their teammates on the field.
Linebackers in 3-4 Defense vs. 4-3 Defense
The main difference between the 3-4 and 4-3 defensive schemes lies in the number and alignment of the linebackers, which affects their roles and responsibilities on the field.
3-4 Defense
In a 3-4 defense, there are three defensive linemen and four linebackers.
The linebackers in a 3-4 defense are typically divided into two categories: inside linebackers and outside linebackers.
- Inside Linebackers: In a 3-4 defense, there are two inside linebackers, commonly referred to as the “Mike” (middle) and “Jack” (weak inside) linebackers. These players are responsible for defending the run and covering short-to-intermediate pass zones. They need to be strong against the run, able to shed blocks, and have good instincts to diagnose plays effectively.
- Outside Linebackers: In a 3-4 defense, there are two outside linebackers, known as the “Sam” (strongside) and “Will” (weakside) linebackers. These players are typically positioned on the edge of the defensive formation. Outside linebackers in a 3-4 defense often have dual roles: setting the edge against the run and providing pass rush. They are expected to be versatile, capable of dropping into coverage, rushing the passer, or stopping the run.
4-3 Defense
In a 4-3 defense, there are four defensive linemen and three linebackers.
The alignment and responsibilities of linebackers in a 4-3 scheme differ from those in a 3-4 scheme.
- Middle Linebacker: In a 4-3 defense, there is a single middle linebacker, often called the “Mike” linebacker. The Mike linebacker is the quarterback of the defense, responsible for making defensive calls, reading the offense, and adjusting the alignment of the front seven accordingly. They are typically strong against the run, skilled at filling gaps, and have good coverage ability.
- Outside Linebackers: In a 4-3 defense, there are two outside linebackers, referred to as the “Sam” (strongside) and “Will” (weakside) linebackers. These players are primarily responsible for covering the flats, providing support against the run, and occasionally rushing the passer. Outside linebackers in a 4-3 scheme often have more coverage responsibilities compared to their counterparts in a 3-4 defense.
Overall, the differences between 3-4 and 4-3 linebackers come down to the number of players at the position, their alignment on the field, and the specific roles and responsibilities assigned to them within their respective defensive schemes.
These variations impact how linebackers contribute to the overall defensive strategy, particularly in run defense, pass coverage, and pass rushing.
