Iso (American Football)
An Iso, short for isolation and also known as a Halfback Lead, is a simple run play in American Football which is designed to isolate the fullback on a lead block with a linebacker, giving the halfback an easy 5 yards. Meanwhile, the other linebackers are blocked on combo blocks from the offensive line. It is one of the most commonly run concepts in football, and is useful in most situations. Types/variants Iso plays are almost always run out of I formations due to the fact that they require a fullback, however, coaches have developed many ways to run them. Quarterback Iso The quarterback iso is a recently developed variant of the iso that is run out of shotgun and pistol formations. Often seen at the youth and high school levels of football, it takes advantage of mobile quarterbacks and uses the halfback as the lead blocker rather than a fullback. It is successful against defenses that put a limited number of players in the box A box (plural: boxes) is a container us ...

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 ...

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] |
Fullback (gridiron Football)
A fullback (FB) is a position in the offensive backfield in gridiron football, and is one of the two running back positions along with the halfback. Fullbacks are typically larger than halfbacks and in most offensive schemes the fullback's duties are split among power running, pass catching, and blocking for both the quarterback and the other running back. Many great runners in the history of American football have been fullbacks, including Jim Brown, Marion Motley, Bronko Nagurski, Jim Taylor, Franco Harris, Larry Csonka, John Riggins, Christian Okoye, and Levi Jackson. However, many of these runners would retroactively be labeled as halfbacks, due to their position as the primary ball carrier; they were primarily listed as fullbacks due to their size and did not often perform the run-blocking duties expected of modern fullbacks. Examples of players who have excelled at the hybrid running–blocking–pass-catching role include Vonta Leach, Mike Alstott, William Henderson, ...

Linebacker
Linebacker (LB) is a playing position in gridiron football. Linebackers are members of the defensive team, and line up three to five yards behind the line of scrimmage and the defensive linemen. They are the "middle ground" of defenders, playing closer to the line of scrimmage than the defensive backs (secondary), but farther back than the defensive linemen. 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 a linebacker plays their position 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 ...

Halfback (American Football)
A halfback (HB) is an offensive position in American football, whose duties involve lining up in the offensive backfield and carrying the ball on most rushing plays, i.e. a running back. When the principal ball carrier lines up deep in the backfield, and especially when that player is placed behind another player (usually a blocking back), as in the I formation, that player is instead referred to as a tailback. Sometimes the halfback can catch the ball from the backfield on short passing plays as they are an eligible receiver. Occasionally, they line up as additional wide receivers. When not running or catching the ball, the primary responsibility of a halfback is to aid the offensive linemen in blocking, either to protect the quarterback or another player carrying the football. History Overview Before the emergence of the T formation in the 1940s, all members of the offensive backfield were legitimate threats to run or pass the ball. Most teams used four offensive back ...

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.

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 ...

Quarterback
The quarterback (commonly abbreviated "QB"), colloquially known as the "signal caller", is a position in gridiron football. Quarterbacks are members of the offensive platoon and mostly line up directly behind the offensive line. In modern American football, the quarterback is usually considered the leader of the offense, and is often responsible for calling the play in the huddle. The quarterback also touches the ball on almost every offensive play, and is almost always the offensive player that throws forward passes. When the QB is tackled behind the line of scrimmage, it is called a sack. Overview In modern American football, the starting quarterback is usually the leader of the offense, and their successes and failures can have a significant impact on the fortunes of their team. Accordingly, the quarterback is among the most glorified, scrutinized, and highest-paid positions in team sports. '' Bleacher Report'' describes the signing of a starting quarterback as a Catch- ...

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.
