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] |
Down (American Football)
A down is a period in which a play transpires in gridiron football. The down is a distinguishing characteristic of the game compared to other codes of football, but is synonymous with a "tackle" in rugby league. The team in possession of the football has a limited number of downs (four in American football, three in Canadian football) to advance ten yards or more towards their opponent's goal line. If they fail to advance that far, possession of the ball is turned over to the other team. In most situations, if a team reaches their final down they will punt to their opponent, which forces their opponent to begin their drive from further down the field; if they are in range, they might instead attempt to score a field goal. Description A down begins with a snap or free kick (such as a kickoff or safety kick), and ends when the ball or the player in possession of it is declared down by an official, a team scores, or the ball or player in possession of it leaves the field of play. ...

High School Football
High school football (french: football au lycée) is gridiron football played by high school teams in the United States and Canada. It ranks among the most popular interscholastic sports in both countries, but its popularity is declining, partly due to risk of injury, particularly concussions. According to ''The Washington Post'', between 2009 and 2019, participation in high school football declined by 9.1%. It is the basic level or step of tackle football. Rules The National Federation of State High School Associations (NFHS) establishes the rules of high school American football in the United States. In Canada, high school is governed by Football Canada and most schools use Canadian football rules adapted for the high school game except in British Columbia, which uses the NFHS rules. Since the 2019 high school season, Texas is the only state that does not base its football rules on the NFHS rule set, instead using NCAA rules with certain exceptions shown below. Through t ...

American Football Strategy
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 ...

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 The T formation is the precursor to most mo ... [...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 ...

One-platoon System
The one-platoon system, also known as iron man football, is a platoon system in American football where players play on both offense and defense. It was the result of smaller roster sizes in the early days of the game and rules that limited player substitutions, rules that are also standard procedure in many other sports but were eliminated in the 1940s as free substitution was legalized. The alternative system is the two-platoon system (or simply the ''platoon system''), which uses separate offensive and defensive units (three platoons if special teams is also counted). Each system was used at different times in American college football and in the National Football League. One-platoon football is seen in modern times mostly on lower-end and smaller teams at the high school and semi-pro levels, where player shortages and talent disparities require it; the system allows teams to play with a smaller roster than a two-platoon or multiple-platoon team, but because players are on the f ...

Penalty (American Football)
In gridiron football, a penalty is a sanction assessed against a team for a violation of the rules, called a foul. Officials initially signal penalties by tossing a bright yellow colored penalty flag onto the field toward or at the spot of a foul. Many penalties result in moving the football toward the offending team's end zone, usually either 5, 10, or 15 yards, depending on the penalty. Most penalties against the defensive team also result in the offense receiving an automatic first down, while a few penalties against the offensive team cause them to automatically lose a down. In some cases, depending on the spot of the foul, the ball is moved half the distance to the goal line rather than the usual number of yards, or the defense scores an automatic safety. Rationale Because football is a high-contact sport requiring a balance between offense and defense, many rules exist that regulate equality, safety, contact, and actions of players on each team. It is very difficult to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Defensive Lineman
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 offens ... [...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, ...
