American Football Defensive Schemes
Strategy forms a major part of American football. 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 in order to win the game. Offensive strategy The goal of the offense is, most generally, to score points. In order to accomplish this goal, coaches and players plan and execute plays – based on a variety of factors: The players involved, the opponent's defensive strategy, the amount of time remaining before halftime or the end of the game, and the number of points needed to win the game. Strategically, the offense can prolong their possession of the ball to prevent the opponent from scoring. Offensive scoring chances, or drives, end when they cannot move the ball 10 yards or th ...

American Football
American football (referred to simply as football in the United States and Canada), also known as gridiron, is a team sport played by two teams of eleven players on a rectangular field with goalposts at each end. The offense, the team with possession of the oval-shaped football, attempts to advance down the field by running with the ball or passing it, while the defense, the team without possession of the ball, aims to stop the offense's advance and to take control of the ball for themselves. The offense must advance at least ten yards in four downs or plays; if they fail, they turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the drive. Points are scored primarily by advancing the ball into the opposing team's end zone for a touchdown or kicking the ball through the opponent's goalposts for a field goal. The team with the most points at the end of a game wins. American football evolved in the United States, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wildcat Formation
Wildcat formation describes a formation for the offense in football in which the ball is snapped not to the quarterback but directly to a player of another position lined up at the quarterback position. (In most systems, this is a running back, but some playbooks have the wide receiver, fullback, or tight end taking the snap.) The Wildcat features an unbalanced offensive line and looks to the defense like a sweep behind zone blocking. A player moves across the formation prior to the snap. However, once this player crosses the position of the running back who will receive the snap, the play develops unlike the sweep. The Wildcat is a gambit rather than an overall offensive philosophy. It can be a part of many offenses. For example, a spread-option offense might use the Wildcat formation to keep the defense guessing, or a West Coast offense may use the power-I formation to threaten a powerful run attack. The Wildcat scheme is a derivation of Pop Warner's Single Wing offense ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Football Plays
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. Order of a play A play begins in one of two ways: *A play from scrimmage begins when the ball is delivered from the center to a back, usually the quarterback. *A free kick Once the play begins, it will continue until one of the following events happens: *The ball carrier is down, usually defined as when any body part besides the hands and feet touches the ground. *The ball carrier's forward progress is stopped to the point where a stalemate occurs and it is clear that the ball cannot be advanced any farther, nor is he easily going down as defined above. *The ball carrier steps ''out of bounds''. *A forward pass touches the ground before it i ...

Quarterback Kneel
In American football and Canadian football, a quarterback kneel, also called taking a knee, genuflect offense, kneel-down offense, or victory formation, occurs when the quarterback immediately kneels to the ground, ending the play on contact, after receiving the snap. It is primarily used to run the clock down, either at the end of the first half (regardless of which team is ahead) or the game itself, to preserve a lead. Although it generally results in a loss of a yard and uses up a down, it minimizes the risk of a fumble, which would give the other team a chance at recovering the ball. The play is meant to keep the defense from seriously challenging for possession of the ball. The rules penalize rough play after the ball is dead, which in this play usually occurs a fraction of a second after the snap. Especially when the outcome of the game is all but certain, defenses will often give little resistance to the play as a matter of sportsmanship as well as to reduce the risk ...

Pistol Formation
The pistol offense is an American football formation and strategy developed by coaches Michael Taylor of Mill Valley, California and popularized by Chris Ault when he was head coach at the University of Nevada, Reno. It is a hybrid of the traditional shotgun and single back offenses. In the pistol offense, also commonly referred to as the "pistol formation", the quarterback lines up four yards behind the center, which is much closer than the seven-yard setback in a traditional shotgun formation. The running back then lines up three yards directly behind the quarterback, which is in contrast to the shotgun, where they are beside each other. It is argued that the position of the quarterback in the pistol formation strikes an advantageous compromise: the quarterback is close enough to the line of scrimmage to be able to read the defense, as with run situation sets such as the I formation, but far enough back to give him extra time and a better vision of the field for passing plays, a ...

List Of Formations In American Football
The following is a list of common and historically significant formations in American football. In football, the formation describes how the players in a team are positioned on the field. Many variations are possible on both sides of the ball, depending on the strategy being employed. On offense, the formation must include at least seven players on the line of scrimmage, including a center to start the play by snapping the ball. There are no restrictions on the arrangement of defensive players, and, as such, the number of defensive players on the line of scrimmage varies by formation. Offensive formations This list is not exhaustive; there are hundreds of different ways to organize a team's players while still remaining within the "7 on the line 4 in the backfield" convention. Still, this list of formations covers enough of the basics that almost every formation can be considered a variant of the ones listed below.

T Formation
In American football, a T formation (frequently called the full house formation in modern usage, sometimes the Robust T) is a formation used by the offensive team in which three running backs line up in a row about five yards behind the quarterback, forming the shape of a "T".Bible, pp. 115-117. Numerous variations of the T formation have been developed, including the Power-T, where two tight ends are used, the Pro T, which uses one tight end and one wide receiver, or the Wing T, where one of the running backs (or wingback) lines up one step behind and to the side of the tight end. Any of these can be run using the original spacing, which produced a front of about seven yards, or the Split-T spacing, where the linemen were farther apart and the total length of the line was from 10 to 16 yards.Faurot, pp. 12-16. History The T formation is often said to be the oldest offensive formation in American football and is claimed to have been invented by Walter Camp in 1882. However, a ...

Single-wing Formation
In American and Canadian football, a single-wing formation 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". Created by Glenn "Pop" Warner, the single wing was superior to the T formation in its ability to get an extra eligible receiver down field. History Among coaches, single-wing football denotes a formation using a long snap from center as well as a deceptive scheme that evolved from Glenn "Pop" Warner's offensive style. Traditionally, the single-wing was an offensive formation that featured a core of four backs including a tailback, a fullback, a quarterback (blocking back), and a wingback. Linemen were set "unbalanced", with two on one side of the center and four on the other. This was done by moving the off-side guard or tackle to the strong side. The single-wing was one of the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
I Formation
The I formation is one of the most common offensive formations in American football. The I formation draws its name from the vertical (as viewed from the opposing endzone) alignment of quarterback, fullback, and running back, particularly when contrasted with the same players' alignments in the ''T formation''. The formation begins with the usual 5 offensive linemen (2 offensive tackles, 2 guards, and a center), the quarterback under center, and two backs in-line behind the quarterback. The base variant adds a tight end to one side of the line and two wide receivers, one at each end of the line. History The exact origin of the I formation is unclear. Charles M. Hollister of Northwestern in 1900 is one source, as is Bob Zuppke in 1914. Tom Nugent is credited with developing the I formation at Virginia Military Institute in 1950 as a replacement for the single-wing and an alternative to the T formation. Don Coryell, before popularizing Air Coryell, was also a pioneer o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wishbone Formation
The wishbone formation, also known simply as the bone, is an offensive formation in American football. The style of attack to which it gives rise is known as the wishbone offense. Like the spread offense in the 2000s to the present, the wishbone was considered to be the most productive and innovative offensive scheme in college football during the 1970s and 1980s. History While the record books commonly refer to Emory Bellard developing the wishbone formation in 1968 as offensive coordinator at Texas, the wishbone's roots can be traced back to the 1950s. According to Barry Switzer, it was Charles “Spud” Cason, football coach at William Monnig Junior High School of Fort Worth, Texas, who first modified the classic T formation in order “to get a slow fullback into the play quicker.” Cason called the formation “Monnig T”. Bellard learned about Cason's tactics while coaching at Breckenridge High School, a small community west of Fort Worth. Earlier in his career Bellard ...

Shotgun Formation
The shotgun formation is a formation used by the offensive team in gridiron football mainly for passing plays, although some teams use it as their base formation. Instead of the quarterback receiving the snap from center at the line of scrimmage, in the shotgun he stands farther back, often five to seven yards off the line. Sometimes the quarterback will have a back on one or both sides before the snap, while other times he will be the lone player in the backfield with everyone spread out as receivers. The shotgun formation can offer certain advantages. The offensive linemen have more room to maneuver behind the scrimmage line and form a tighter, more cohesive oval “pocket” in which the quarterback is protected from “blitzing” by the defense. If the quarterback has speed, mobility or both, he can use this formation to scramble before his pass; or, to run to an open field position in the defensive secondary or to the sideline, usually gaining first-down yardage.
