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 with zone 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. Requirements The play requires a fullback ...

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 i ...

American Football
American football, referred to simply as football in the United States and Canada and also known as gridiron football, is a team sport played by two teams of eleven players on a rectangular American football field, field with goalposts at each end. The offense (sports), offense, the team with possession of the oval-shaped Ball (gridiron football), football, attempts to advance down the field by Rush (gridiron football), running with the ball or Forward pass#Gridiron football, throwing it, while the Defense (sports), 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 the ball at least ten yard, yards in four Down (gridiron football), downs or plays; if they fail, they turnover on downs, turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the Glossary of American football#drive, drive.

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, Tom Rathman, 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 Mike Alstott, Larry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linebacker
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 so back up the defensive linemen. They play closer to the line of scrimmage than the defensive backs (secondary). 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 is frequently the "quarterback of the defense". His central role on the field means he is in the best positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halfback (American Football)
A halfback (HB) is an Offense (sports), offensive position in American football, whose duties involve lining up in the offensive backfield and Carry (gridiron football), carrying the ball (gridiron football), ball on most rush (gridiron football), rushing American football plays, 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 (American football), blocking back), as in the I formation, that player is instead referred to as a tailback (TB). 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. The term "halfback" has seen a decline since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 further 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. The quarterback also has a better view of the defense from the shotgun formation. 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 ...

Pistol Formation
A pistol is a type of handgun, characterised by a barrel with an integral chamber. The word "pistol" derives from the Middle French ''pistolet'' (), meaning a small gun or knife, and first appeared in the English language when early handguns were produced in Europe. In colloquial usage, the word "pistol" is often used as a generic term to describe ''any'' type of handgun, inclusive of revolvers (which have a single barrel and a separate cylinder housing multiple chambers) and the pocket-sized derringers (which are often multi-barrelled). The most common type of pistol used in the contemporary era is the semi-automatic pistol. The older single-shot and lever-action pistols are now rarely seen and used primarily for nostalgic hunting and historical reenactment. Fully-automatic machine pistols are uncommon in civilian usage because of their generally poor recoil-controllability (due to the lack of a buttstock) and strict laws and regulations governing their manufacture and s ...

Quarterback
The quarterback (QB) is a position in gridiron football who are members of the offensive side of the ball and mostly line up directly behind the Lineman (football), 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 Quarterback sack, sack. The position is also colloquially known as the "signal caller" and "field general". The quarterback is widely considered the most important position in American football, and one of the most important positions in team sports. 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.

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 p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
