Skill positions in gridiron football are the positions that ordinarily handle the ball and are most responsible for scoring points. Offensive players such as quarterbacks, running backs, and wide receivers are typically considered skill positions. Defensive backs primarily playing corner are also classified as a skill positionas are tight ends on occasion.
Gridiron football, also known as North American football or, in North America, simply football, is a football sport primarily played in the United States and Canada. American football, which uses 11-player teams, is the form played in the United States and the best known form of gridiron football worldwide, while Canadian football, featuring 12-player teams, predominates in Canada. Other derivative varieties include indoor football, football for smaller teams, and informal games such as touch and flag football. Football is played at professional, collegiate, semi-professional, and amateur levels.
In American football each team has 11 players on the field at one time. The specific role that a player takes on the field is called their position. Under the modern rules of American football, teams are allowed unlimited substitutions; that is, teams may change any number of players after any play. This has resulted in the development of three "platoons" of players: the offense, the defense, and the special teams. Within those platoons, various specific positions exist depending on what each player's main job is.
A quarterback, colloquially known as the "signal caller", is a position in American and Canadian football. Quarterbacks are members of the offensive team and line up directly behind the offensive line. In modern American football, the quarterback is usually considered the leader of the offensive team, and is often responsible for calling the play in the huddle. The quarterback also touches the ball on almost every offensive play, and is the offensive player that almost always throws forward passes.
Skill positions are contrasted with linemen and defensive players.Skill position players are generally smaller than linemen, but they must also be faster and have other talents; such as the ability to throw, handle or catch the ball, avoid tacklers, or read and exploit defensive weaknesses; which are less of a priority for linemen.
A running back (RB) is an American and Canadian football position, a member of the offensive backfield. The primary roles of a running back are to receive handoffs from the quarterback for a rushing play, to catch passes from out of the backfield, and to block. There are usually one or two running backs on the field for a given play, depending on the offensive formation. A running back may be a halfback, a wingback or a fullback. A running back will sometimes be called a "feature back" if he is the team's starting running back.
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.
A linebacker is a playing position in American football and Canadian football. Linebackers are members of the defensive team, and line up approximately three to five yards behind the line of scrimmage, behind the defensive linemen, and therefore "back up the line". Linebackers generally align themselves before the ball is snapped by standing upright in a "two-point stance".
The tight end (TE) is a position in American football, arena football, and formerly Canadian football, on the offense. The tight end is often seen as a hybrid position with the characteristics and roles of both an offensive lineman and a wide receiver. Like offensive linemen, they are usually lined up on the offensive line and are large enough to be effective blockers. On the other hand, unlike offensive linemen, they are eligible receivers adept enough to warrant a defense's attention when running pass patterns.
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 defensemen behind the rushers to stop the play.
In American and Canadian football, a single-wing formation, created by Glenn "Pop" Warner, was a precursor to the modern spread or shotgun formation. The term usually connotes formations in which the snap is tossed rather than handed—formations with one wingback and a handed snap are commonly called "wing T" or "winged T". The single wing was superior to the T formation in its ability to get an extra eligible receiver down field.
This is a glossary of terms used in Canadian football. The Glossary of American football article also covers many terms that are also used in the Canadian version of the game.
A rugby league team consists of thirteen players on the field, with four substitutes on the bench. Each of the thirteen players is assigned a position, normally with a standardised number, which reflects their role in attack and defence, although players can take up any position at any time.
Strategy forms a major part of the game of American football, and both teams plan many aspects of their plays (offense) and response to plays (defense), such as what formations they take, who they put on the field, and the roles and instructions each player are given. Throughout a game, each team adapts to the other's apparent strengths and weaknesses, trying various approaches to outmaneuver or overpower their opponent to score more points in order to win the game.
A formation in 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.
In sports, a starting lineup is an official list of the set of players who will participate in the event when the game begins. The players in the starting lineup are commonly referred to as starters, whereas the others are substitutes or bench players.
In American football, a zone blitz is a defensive tactic that sends additional players to rush the opposing team's quarterback, whilst also unexpectedly redirecting a supposed pass rushing player into pass coverage instead. This tactic also likely includes zone coverage.
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.
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 their playbook.
The prevent defense is a defensive alignment in American football that seeks to prevent the offense from completing a long pass or scoring a touchdown in a single play and seeks to run out the clock. It is used by a defense that is winning by more than a touchdown, late in the fourth quarter, or in specific situations, such as third-and-very-long if it seems clear that the offense must pass the football to gain long yardage.
The following terms are used in American football, both conventional and indoor. Some of these terms are also in use in Canadian football; for a list of terms unique to that code, see Glossary of Canadian football.
Players in the National Football League wear uniform numbers between 1 and 99, and no two players on a team may wear the same number on the field at the same time. Rules exist which tie a player's number to a specific range of numbers for their primary position. Additionally, rules exist which limit who may handle the ball on offense, generally players who are designated as offensive lineman, who wear numbers 50-79, are not allowed to handle the ball during a play from scrimmage, though they are allowed to do so if they report to the referee as playing out of position.
