Defensive Halfback
The halfback in Canadian football, and most commonly the Canadian Football League, currently refers to the defensive back rather than the running back, as in American football. The defensive halfback lines up inside covering the slotback. They are usually slightly larger than the cornerback to assist the linebackers in stopping the run. They can also be seen backing off the line early, to counter the forward motion of a slotback, which is allowed before the snap in the CFL. The cause of the difference in naming between the two positions between the American and Canadian game, which otherwise uses the same names for positions, stems from the early history of the game. In both games, the early formations featured identical offensive and defensive formations, with seven down linemen and four players (five in Canada) in the backfield. Thus, both the offense ''and'' defense had quarterbacks, halfbacks and fullbacks. Over the course of the 20th century, the American and Canadian games ...

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, ...

Canadian Football League
The Canadian Football League (CFL; french: Ligue canadienne de football—LCF) is a professional sports league in Canada. The CFL is the highest level of competition in Canadian football. The league consists of nine teams, each located in a city in Canada. They are divided into two divisions: four teams in the East Division and five teams in the West Division. As of 2022, it features a 21-week regular season in which each team plays 18 games with three bye weeks. This season traditionally runs from mid-June to early November. Following the regular season, six teams compete in the league's three-week playoffs, which culminate in the Grey Cup championship game in late November. The Grey Cup is one of Canada's largest annual sports and television events. The CFL was officially named on January 19, 1958, upon the merger between the Interprovincial Rugby Football Union or "Big Four" (founded in 1907) and the Western Interprovincial Football Union (founded in 1936).

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] |
Running Back
A running back (RB) is a member of the offensive backfield in gridiron football. The primary roles of a running back are to receive American football plays#Offensive terminology, handoffs from the quarterback to Rush (American football)#Offense, rush the ball, to line up as a receiver to catch the ball, and Blocking (American football), 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 (American football), halfback (in certain contexts also referred to as a "tailback" — see #Halfback/tailback, below), a wingback (American football), wingback or a Fullback (American football), fullback. A running back will sometimes be called a "feature back" if he is the team's starting running back. Halfback/tailback The halfback (HB) or tailback (TB) position is responsible for carrying the ball on the majority of running plays, and may frequently be used as a receiver on ...

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] |
Slotback
Slotback, sometimes referred to as an A-back or slot receiver, is a position in gridiron football. The "slot" is the area between the last offensive lineman on either side of the center and the wide receiver on that side. A player who lines up between those two players and behind the line of scrimmage fills that "slot." The slotback position is a fixture of Canadian football and indoor football where they act as extra receivers. It is also used in American football where the position requires a versatile player, who must combine the receiving skills of a wide receiver, the ball-carrying skills of a running back, and the blocking skills of a tight end. A similarly named position is the slot receiver, who is the third wide receiver in a 3-receiver set, the one who lines up between the outermost receiver and the end of the offensive line. Slotbacks are often as many as five yards behind the line of scrimmage when the ball is snapped and, in the Canadian and indoor game, may ...

Cornerback
A cornerback (CB) is a member of the defensive backfield or secondary in gridiron football. Cornerbacks cover receivers most of the time, but also blitz and defend against such offensive running plays as sweeps and reverses. They create turnovers through hard tackles, interceptions, and deflecting forward passes. Other members of the defensive backfield include strong and free safeties. The cornerback position requires speed, agility, strength, and the ability to make rapid sharp turns. A cornerback's skill set typically requires proficiency in anticipating the quarterback, backpedaling, executing single and zone coverage, disrupting pass routes, block shedding, and tackling. Cornerbacks are among the fastest players on the field. Because of this, they are frequently used as return specialists on punts or kickoffs. Overview The cornerback’s chief responsibility is to defend against the offense's pass. The rules of American professional football and American coll ...

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 ...

Motion (football)
In gridiron football, motion refers to the movement of an offensive player at the time of the snap. While there are different rules regarding motion, most mandate that no more than one player may be in motion at the time of the snap, and the player must not be an offensive lineman (typically, the player in motion is a wide receiver or running back). Additionally, the NFL (professional), NCAA (college), and NFHSAA (high school) require that they be moving laterally or backwards; they are not allowed to be moving towards the line of scrimmage when the ball is snapped. The Canadian Football League and the Arena Football League allow for motion towards the line of scrimmage at the time of the snap. Motion and shift There is a distinction drawn between a ''shift'' and ''motion'' in football. Motion occurs when a player is moving ''at the time of the snap''. A shift occurs when one or more players changes their position on the offensive side of the ball ''before the snap'', causing ...

History Of American Football
The history of American football can be traced to early versions of rugby football and association football. Both games have their origin in multiple varieties of football played in the United Kingdom in the mid-19th century, in which a football is kicked at a goal or kicked over a line, which in turn were based on the varieties of English public school football games descending from medieval ball games. American football resulted from several major divergences from association football and rugby football. Most notably the rule changes were instituted by Walter Camp, a Yale University athlete and coach who is considered to be the "Father of American Football". Among these important changes were the introduction of the line of scrimmage, of down-and-distance rules, and of the legalization of forward pass and blocking. In the late 19th and early 20th centuries, gameplay developments by college coaches such as Eddie Cochems, Amos Alonzo Stagg, Parke H. Davis, Knute Rockne, and ...

Forward Pass
In several forms of football, a forward pass is the throwing of the ball in the direction in which the offensive team is trying to move, towards the defensive team's goal line. The forward pass is one of the main distinguishers between gridiron football (American football and Canadian football) in which the play is legal and widespread, and rugby football (union and league) from which the North American games evolved, in which the play is illegal. The development of the forward pass in American football shows how the game has evolved from its rugby roots into the distinctive game it is today. Illegal and experimental forward passes had been attempted as early as 1876, but the first legal forward pass in American football took place in 1906, after a change in rules. Another change in rules occurred on January 18, 1951, which established that no center, tackle, or guard could receive a forward pass, unless such a player announces his intent to the referee beforehand that he will ...

Formation (American Football)
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. Offense At the highest level of play in the NFL and NCAA, the one constant in all formations is the offensive line, consisting of the left and right tackle, left and right guard, and a center. These five positions are often referred to collectively as the "line", and have the primary role of blocking. By rule there must be two additional players on the line of scrimmage called ends. These players are eligible receivers and may play near the linemen (tight ends) or farther away ( split end or wide receiver). Most teams play additional players near (but still off) the line of scrimmage to act as extra pass receivers. Offensive positions Up to four players can be behind the offensive line, but one is always designated the quarterb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
