Linebacker (LB) is a playing position in gridiron football. Linebackers are members of the defensive team, and typically line up three to five yards behind the line of scrimmage and the defensive linemen, playing closer to the line of scrimmage than the defensive backs (secondary).

Contents

As such, linebackers play a hybrid role and are often the most versatile players on the defensive side of the ball; they can be asked to play roles similar to either a defensive lineman (such as stopping the runner on a running play) or a defensive back (such as dropping back into pass coverage). How linebackers play their positions depends on the defensive alignment, the philosophy of the coaching staff, and the particular play the offense may call.

Linebackers are divided into middle linebackers, sometimes called inside linebackers, and outside linebackers. The middle linebacker, often called "Mike", is frequently the "quarterback of the defense". His central role on the field means he is in the best position to call defensive plays and direct shifts and changes based on what the offense is doing. Outside linebackers are often in a position to blitz, a defensive maneuver where the player rushes into the offensive backfield to disrupt a running play or sack the quarterback on passing plays. Besides "Mike", other nicknames such as "Sam", "Will", or "Jack", are commonly used to refer to various linebacking roles.

Historically, some of the most impactful defensive players, such as Pro Football Hall of Fame members Chuck Bednarik, Dick Butkus, Jack Lambert, Ray Lewis, Ray Nitschke, Mike Singletary, Brian Urlacher, and Lawrence Taylor, were linebackers.

Before the advent of the two-platoon system with separate units for offense and defense, the player who was the team's center on offense was often, though not always, the team's linebacker on defense. Hence, in contemporary football, one usually sees four defensive linemen to the offense's five or more. Most sources claim coach Fielding H. Yost and center Germany Schulz of the Michigan invented the position. [2] [3] [4] [5] [6] Schulz was Yost's first linebacker in 1904 when he stood up from his usual position on the line. Yost was horrified at first, but came to see the wisdom in Schulz's innovation. [7] William Dunn of Penn State was another Western Conference linebacker soon after Schulz.

However, there are various historical claims tied to the linebacker position, including some before 1904. For example, Percy Given of Georgetown is another center with a claim to the title "first linebacker," supposedly standing up behind the line well before Schulz in a game against Navy in 1902. [8] Other sources have the first linebacker in the South as Frank Juhan, who played at Sewanee during 1908–1910. [9]

In the East, Ernest Cozens of Penn was "one of the first of the roving centers," [10] another archaic term for the position, supposedly coined by Hank Ketcham of Yale. [11] Walter E. Bachman of Lafayette was said to be "the developer of the 'roving center' concept". [12] Edgar Garbisch of Army was credited with developing the "roving center method" of playing defensive football in 1921. [13]

In professional football, Cal Hubbard is credited with pioneering the linebacker position. He starred as a tackle and end, playing off the line in a style similar to that of a modern linebacker. [14]

Types

Middle linebacker

The middle or inside linebacker (MLB or ILB), sometimes called the "Mike" or "Mac", [15] is often referred to as the "quarterback of the defense". [16] Often it is the middle linebacker who receives the defensive play calls from the sideline and relays that play to the rest of the team, and in the NFL he is usually the defensive player with the electronic sideline communicator. A jack-of-all-trades, the middle linebacker can be asked to blitz (though they often blitz less than the outside linebacker), cover, spy the quarterback, or even have a deep middle-of-the-field responsibility in the Tampa 2 defense. In standard defenses, middle linebackers commonly lead the team in tackles. The terms middle and inside linebacker are often used interchangeably; [17] they are also used to distinguish between a single middle linebacker playing in a 4–3 defense, and two inside linebackers playing in a 3–4 defense. [18] In a 3–4 defense, the larger, more run-stopping-oriented linebacker is usually still called "Mike", while the smaller, more pass protection/route coverage-oriented player is called "Will". [19] "Mikes" usually line up towards the strong side or on the side the offense is more likely to run on (based on personnel matchups) while "Wills" may line up on the other side or even a little farther back between the defensive line and the secondary. [19]

Outside linebacker

The outside linebacker (OLB), sometimes called the "Buck, Sam, and Rebel", is usually responsible for outside containment. This includes the strongside and weakside designations below. They are also responsible for blitzing the quarterback. Not only is the OLB responsible for outside containment and blitzing the QB, but they also have to perform pass coverage in the flats – sometimes called a drop. Outside linebackers pass coverages covers quick slants outside, in curls in the flats. The "flats" are the edge of the field closest to the sideline, from the line of scrimmage down about ten yards. John Alexander is the first person to have played outside linebacker in the NFL.[ citation needed ]

Strongside linebacker

The strongside linebacker (SLB) is often nicknamed the "Sam" for purposes of calling a blitz. Since the strong side of the offensive team is the side on which the tight end lines up, or whichever side contains the most personnel, the strongside linebacker usually lines up across from the tight end. Often the strongside linebacker will be called upon to tackle the running back on a play because the back will be following the tight end's block. He is most often the strongest linebacker; at the least he possesses the ability to withstand, shed, and fight off blocks from a tight end or fullback blocking the backside of a pass play. The linebacker should also have strong safety abilities in pass situation to cover the tight end in man on man situations. He should also have considerable quickness to read and get into coverage in zone situations. The strongside linebacker is also commonly known as the left outside linebacker (LOLB).[ citation needed ]

Weakside linebacker

The weakside linebacker WLB), or the "Will" in 4–3 defense, sometimes called the backside linebacker, or "Buck", as well as other names like Jack or Bandit, [15] must be the fastest of the three, because he is often the one called into pass coverage. He is also usually chasing the play from the backside, so the ability to maneuver through traffic is a necessity for the Will. The Will usually aligns off the line of scrimmage at the same depth as Mike. Because of his position on the weakside, the Will does not often have to face large interior linemen one on one unless one is pulling. In coverage, the Will often covers the back that attacks his side of the field first in man coverage, while covering the weak flat in Texas Loop or hooks/curl areas in zone coverage. The weakside linebacker is also commonly known as the right outside linebacker (ROLB).[ citation needed ]

Formations

The number of linebackers is dependent upon the formation called for in the play; formations can call for as few as none, or as many as seven. Most defensive schemes call for three or four, which are generally named for the number of linemen, followed by the number of linebackers (with the 46 defense being an exception). For example, the 4–3 defense has four defensive linemen and three linebackers; conversely, the 3–4 defense has three linemen and four linebackers.

4–3 defense

In the 4–3 defense there are four down linemen and three linebackers. The middle linebacker is designated "Mike" (or "Mac") and two outside linebackers are designated "Sam" and "Will" according to how they line up against the offensive formation. If there is a strong call, the linebacker on the strongside is called "Sam", while the linebacker on the weakside is called "Will". The outside linebacker's job is to cover the end to make sure a run does not escape and to watch the pass and protect from it. The middle linebacker's job is to stop runs between the tackles and watch the entire field to see the play develop. On pass plays, the linebackers' responsibilities vary based upon whether a man or zone coverage is called. In zone coverage, the linebackers will generally drop into hook zones[ clarification needed ] across the middle of the field. However, some zones will send the outside linebackers into the flats (area directly to the left and right of the hash marks, extending 4–5 yards downfield). In a man-to-man call, the "Sam" will often cover the tight end with help from a safety over the top, while at other times, the "Sam" and "Will" will be responsible for the first man out of the backfield on their side of the center, with the "Mike" covering if a second man exits on that side of the field.

In the "Tampa 2" zone defense, the middle linebacker is required to drop quickly into a deep middle zone pass coverage thus requiring a quick player at this position.

3–4 defense

A base 3-4 defense Linebacker34.svg
A base 3–4 defense

In the 3–4 defense three linemen play the line of scrimmage and four linebackers back them up, typically two outside linebackers and two inside linebackers. The weakside inside linebacker is typically called the "Will", while the strong side or middle inside linebacker is called the "Mike". "Sam" is a common designation for strong outside linebacker, while the other position is usually called "Jack" and is often a hybrid DE/LB. Usually, teams that run a 3–4 defense look for college defensive ends that are too small to play the position in the pros and not quite fluid enough to play outside linebacker in a 4–3 defense as their "Jack" linebacker.[ citation needed ]

The idea behind the 3–4 defense is to disguise where the fourth rusher will come from. Instead of the standard four down-linemen in the 4–3, only three players are clearly attacking nearly every play. A key for running this defense successfully is having a defensive front of three large defensive linemen who command constant double teams. In particular, the nose tackle, who plays over the offensive center, must be able to hold ground and to occupy several offensive blockers to allow the linebackers to make plays. The focus of the 3–4 defensive line is to occupy offensive linemen thus freeing the linebackers to tackle the running back or to rush the passer or otherwise drop into pass coverage.

The primary responsibilities for both outside linebackers are typically to stop the run and rush the quarterback in passing situations, in which they line in front of the tackles like true defensive ends. The outside linebackers in a 3–4 defense must be very skilled at rushing the quarterback, and would be playing defensive end in a 4–3 defense. Among inside linebackers, one is generally a run-stuffer who is better able to handle offensive linemen and stop running backs, while the other is often a smaller, faster player who excels in pass coverage. However, the smaller or cover LB should also be able to scrape and plug running lanes decently.

The design concept of the 3–4 defense is to confuse the offensive line in their blocking assignments, particularly in pass blocking, and to create a more complex read for the quarterback. Many 3–4 defenses have the ability to quickly morph into a 4–3 on the field.

46 defense

In the 46 defense, there are four linemen, three linebackers and a safety who is moved up behind the line of scrimmage. Thus, it appears as if there are four linebackers, but it is really three linebackers with one safety playing up with the other linebackers.

Three of the defensive linemen are over both of the offensive guards and the center, thereby making it difficult to double-team any one of the three interior defensive linemen. This can also take away the ability of the offense to pull the guards on a running play, because this would leave one of the defenders unblocked, or, at best, give another lineman a very difficult block to make on one of the defenders. The safety, like the linebacker, can blitz, play man-on-man, play zone, or drop back into deep coverage like a normal safety would do. The 46 is used in heavy run situations to stop the run, when a team wants to apply much pressure, or merely to confuse the quarterback and offensive line.

4–4 defense

This defense is effective at run-stopping but is weaker than a 4–3 defense at pass coverage because it uses only three defensive backs. This defensive scheme is often played with two inside line backers and two outside line backers. The names of the two inside line backers are often called Sam and Mike and these two are lined up about four yards from the line of scrimmage and are lined up with the offensive guard. The inside line backers are often more of a run player so they will defend the run before they will the pass. These line backers will be reading the offensive guard so they know what to do, so if the guard sets up to pass block the line backers know to get into their zone in order to cover the pass. If the guard come out for a run play they know that they need to fill the gap that they are supposed to so that they can make a play if it comes to them. Also, these inside line backers are often called on a blitz which is when no matter what the offense does, as soon as that ball is snapped they are shooting their gap and trying to get into the back field to make a play as fast as possible. Outside line backers sometimes are considered to be pass players before they are run players. But that depends on where they are lined up, if they are outside of the box of the defense then they will be pass first players, but if they play inside the box lined up behind the defensive end then they are typically a run player. One of the outside linebackers is usually called into either blitz or pass coverage to make up for the missing defensive back. In the NFL and college football, this alignment is used mainly in short yardage situations or near the goal line. It is commonly used in high school football.

In gridiron football, a lineman is a player who specializes in play at the line of scrimmage. The linemen of the team currently in possession of the ball are the offensive line, while linemen on the opposing team are the defensive line. A number of NFL rules specifically address restrictions and requirements for the offensive line, whose job is to help protect the quarterback from getting sacked for a loss, or worse, fumbling. The defensive line is covered by the same rules that apply to all defensive players. Linemen are usually the largest players on the field in both height and weight, since their positions usually require less running and more strength than skill positions.

<span class="mw-page-title-main">Cornerback</span> Position in gridiron football

A cornerback (CB) is a member of the defensive backfield or secondary in gridiron football. Cornerbacks cover receivers most of the time, but also blitz and defend against such offensive running plays as sweeps and reverses. They create turnovers through hard tackles, interceptions, and deflecting forward passes.

<span class="mw-page-title-main">Screen pass</span> Kind of play in North American football

A screen pass is a play in gridiron football consisting of a short pass to a receiver who is protected by a screen of blockers. During a screen pass, a number of things happen concurrently in order to fool the defense into thinking a long pass is being thrown, when in fact the pass is merely a short one, just beyond the defensive linemen. Screens are usually deployed against aggressive defenses that rush the passer. Because screens invite the defense to rush the quarterback, they are designed to leave fewer defensive players behind the rushers to stop the play.

In gridiron football, blitzing is a tactic used by the defense to disrupt pass attempts by the offense. During a blitz, a higher than usual number of defensive players will rush the opposing quarterback, in an attempt either to tackle them or force them to hurry their pass attempt.

Strategy plays a crucial role in American football. Both teams carefully plan various aspects of their gameplay in an effort to win. This includes deciding on formations, selecting players for specific positions, and assigning roles and instructions to each player on offense and defense.

The 46 defense is an American football defensive formation, an eight men in the box defense, with six players along the line of scrimmage. There are two players at linebacker depth playing linebacker technique, and then three defensive backs. The 46 defense was originally developed and popularized with the Chicago Bears by their defensive coordinator Buddy Ryan, who later became head coach of the Philadelphia Eagles and Arizona Cardinals.

A formation in American football refers to the position players line up in before the start of a down. There are both offensive and defensive formations and there are many formations in both categories. Sometimes, formations are referred to as packages.

The Tampa 2 is an American football defensive scheme popularized by the Tampa Bay Buccaneers National Football League (NFL) team in the mid-1990s–early 2000s. The Tampa 2 is typically employed out of a 4–3 defensive alignment, which consists of four linemen, three linebackers, two cornerbacks, and two safeties. The defense is similar to a Cover 2 defense, except the middle linebacker drops into a deep middle coverage for a Cover 3 when he reads a pass play.

<span class="mw-page-title-main">American football positions</span> Specific roles that players take in American football

In American football, the specific role that a player takes on the field is referred to as their "position". Under the modern rules of American football, both teams are allowed 11 players on the field at one time and have "unlimited free substitutions", meaning that they may change any number of players during any "dead ball" situation. This has resulted in the development of three task-specific "platoons" of players within any single team: the offense, the defense, and "special teams". Within these three separate "platoons", various positions exist depending on the jobs that the players are doing.

There are several defensive formations commonly used in eight-man football. Defensive formations are classified by the total number of linemen and linebackers in the formation. The three basic types of formations in eight-man football are seven-man fronts, six-man fronts and five-man fronts.

In American football, a play is a close-to-the-ground plan of action or strategy used to move the ball down the field. A play begins at either the snap from the center or at kickoff. Most commonly, plays occur at the snap during a down. These plays range from basic to very intricate. Football players keep a record of these plays in a playbook.
