Stunt (gridiron Football)
A stunt in American football and Canadian football, sometimes called a twist, is a planned maneuver by a pair of players of the defensive team by which they exchange roles to better slip past blockers of the offensive team at the beginning of a play, in order to better rush the passer. The purpose of a stunt is to confuse opposing blockers, which is an aid to the defense in rushing an opposing forward pass or kick. The main weakness of a stunt is that it is more vulnerable than average to running plays by the opposing team. In most cases, the defense will not use a play incorporating stunting if it expects a running play from the offense. There are two main types of stunts. In one, a line player, who would otherwise try to charge forward, instead drops back, and a nearby linebacker or defensive back charges forward instead. In the other, which is known as ''cross-rushing'', line players, instead of charging straight ahead, cross paths. One of them may follow a looping path tha ...

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] |
Canadian Football
Canadian football () is a team sport, sport played in Canada in which two teams of 12 players each compete for territorial control of a field of play long and wide attempting to advance a pointed oval-shaped ball into the opposing team's scoring area (end zone). In Canada, ''football'' may refer to Canadian football and American football collectively, or to either sport specifically, depending on context. Outside of Canada, the term Canadian football is used exclusively to describe this sport, even in the United States; the term ''gridiron football'' (or, more rarely, ''North American football'') is also used worldwide as well to refer to both sports collectively. The two sports have shared origins and are closely related but have comparison of American and Canadian football, some key differences. With the probable exception of a few minor and recent changes, for which there is circumstantial evidence to suggest the existence of at least informal cross-border collaboration, ...

Defensive Team
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 team with possession of the ball, which is trying to score), the defense (the team trying to prevent the other team from scoring, and to take the ball from them), and the so-called 'special teams' (who play in all kicking situations). Within these three separate "platoons", various positions exist depending on the jobs that the players are doing. Offense In American football, the offense is the team that has possession of the ball and is advancing toward the opponent's end zone to score points. The eleven players of the offen ...

Blocking (American Football)
In American football, blocking or interference (or running interference) involves legal movements in which one player uses his body to obstruct another player's path. The purpose of blocking is to prevent defensive players from tackling the ball carrier, or to protect a quarterback who is attempting to pass, hand off or run the ball. Offensive linemen and fullbacks tend to do the most blocking, although wide receivers are often asked to help block on running plays and halfbacks may be asked to help block on passing plays, while tight ends perform pass blocking and run blocking if they are not running routes to receive passes. Overall, blocking is a skill that virtually every football player may be required to do at some point, even defensive players in the event of a turnover. Essentially, blocking is pushing, with certain restrictions; in blocking one may not grasp another player or do any sort of pulling, and the hands must not extend beyond the line of each armpit; otherwise ...

Pass Rush
On defense in American football, a pass rush is charging across the line of scrimmage towards the quarterback in an effort to stop or " sack" them. The purpose is tackling, hurrying or flushing the quarterback out of their protective pocket or the play's design. "Pressures" and "hurries" are terms used to describe pass rushes which successfully alter a quarterback's performance on a play - forcing them to throw before they find their best target or scramble out of the pocket to elude being tackled - that fall short of completed sacks. A related form of defensive rush is to disrupt or sack a kicker attempting to kick a field goal, extra point, or punt the ball. On offense, "rushing" is to run forward with the ball to gain yardage. In both college and professional football, getting a strong pass rush is an important skill, as even an average quarterback can be productive if he has enough time to find an open receiver, even against a good secondary. To increase pressure, teams w ... [...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 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 ...

Defensive Back
In gridiron football, defensive backs (DBs), also called the secondary, are the players on the defensive side of the ball who play farthest back from the line of scrimmage. They are distinguished from the other two sets of defensive players, the defensive linemen who play directly on the line of scrimmage, and the linebackers, who play in the middle of the defense, between the defensive line and the defensive backs. Among the defensive backs, there are two main types, cornerbacks, which play nearer the line of scrimmage and the sideline, whose main role is to cover the opposing team's wide receivers, and the Safety (gridiron football position), safeties, who play further back near the center of the field, and who act as the last line of defense. American defensive formations usually includes two of each, a left and right cornerback, as well as a strong safety and a free safety, with the free safety tending to play further back than the strong safety. In Canadian football, which ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walter Camp
Walter Chauncey Camp (April 7, 1859 – March 14, 1925) was an American football player, coach, and sports writer known as the "Father of American Football". Among a long list of inventions, he created the sport's line of scrimmage and the system of downs. With John Heisman, Amos Alonzo Stagg, Pop Warner, Fielding H. Yost, and George Halas, Camp was one of the most accomplished persons in the early history of American football. He attended Yale College, where he played and coached college football. Camp's Yale teams of 1888, 1891, and 1892 have been recognized as national champions. Camp was inducted into the College Football Hall of Fame as a coach during 1951. Camp wrote articles and books on the gridiron and sports in general, annually publishing an "All-American" team. By the time of his death, he had written nearly 30 books and more than 250 magazine articles. Life Camp was born in New Britain, Connecticut, the son of Leverett Camp and Ellen Sophia (Cornwell) Camp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lineman (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. Offensive line The offensive line consists of the center, who is responsible for snapping the ball into play, two guards who flank the center, and two offensive tackles who flank the guards. In addition, a full offensive line may also include a tight end outside one or both of the tackles. An offensi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Scrum-half (rugby Union)
In the game of rugby union, there are 15 players on each team, comprising eight forwards (wearing jerseys numbered 1–8) and seven backs (numbered 9–15). In addition, there may be up to eight replacement players "on the bench", numbered 16–23. Players are not restricted to a single position, although they generally specialise in just one or two that suit their skills and body types. Players that play multiple positions are called "utility players". Forwards compete for the ball in scrums and line-outs and are generally bigger and stronger than the backs. Props push in the scrums, while the hooker tries to secure the ball for their team by "hooking" it back with their heel. The hooker is also the one who is responsible for throwing the ball in at line-outs, where it is mostly competed for by the locks, who are generally the tallest players on the team. The flankers and number eight are expected to be the first players to arrive at a breakdown and play an important role in se ...
