A hard count by a quarterback at the beginning of a gridiron football play is an audible snap count that uses an irregular, accented (thus, the term "hard") cadence. When used, the center will hike the ball to the quarterback on an accented syllable (for example, "hut one ... hut two ... hut three ... hut hut HUT").
Quarterbacks can use a snap with two or more accented syllables in the hope of drawing an opposing player offside before the last accented syllable (for example, "hut one ... hut two ... hut three hut HUT ... hut HUT"). A loud home crowd can deprive a visiting quarterback of the ability to use this strategy.
This play is often used in a fourth down situation, when fewer than 5 yards are needed for a first down. If the defense jumps offside, they are penalized 5 yards, resulting in a first down for the offense.
When used on fourth down if the defense does not go offside, the offense can either call a time out or take a five-yard penalty for delay of game and punt the ball away, or purposefully done to burn time near the end of the game and kick a field goal to tie or win the game.
If the defense jumps offside, but the offense begins their play, it is called a "free play", because if the offense gains yardage or scores a touchdown, they can decline the penalty and benefit from the gain or score, while if they execute a risky pass that is intercepted or are in their own end zone and are taken down for a safety, the turnover or defensive score is nullified by the offsides penalty.
The offense may choose to use the hard count throughout the game, in an attempt to confuse the defense, and get them to play more conservatively.
The offense's own offensive line is sometimes fooled by the hard count, resulting in a false start offensive infraction.
Canadian football is a sport played in Canada in which two teams of 12 players each compete for territorial control of a field of play 110 yards (101 m) long and 65 yards (59 m) wide attempting to advance a pointed oval-shaped ball into the opposing team's scoring area.
A snap is the backwards passing of the ball in gridiron football at the start of play from scrimmage.
The quarterback, colloquially known as the "signal caller", is a position in gridiron football. Quarterbacks are members of the offensive team and line up directly behind the offensive line. In modern American football, the quarterback is usually considered the leader of the offensive team, and is often responsible for calling the play in the huddle. The quarterback also touches the ball on almost every offensive play, and is the offensive player that almost always throws forward passes. When the QB is tackled behind the line of scrimmage, it is called a sack.
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.
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 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 them to begin their drive from further down the field; if they are in range, they might instead attempt to score a field goal.
This is a glossary of terms used in Canadian football. The Glossary of American football article also covers many terms that are also used in the Canadian version of the game.
American and Canadian football are gridiron codes of football that are very similar; both have their origins in rugby football, but some key differences exist.
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.
Gameplay in American football consists of a series of downs, individual plays of short duration, outside of which the ball is dead or not in play. These can be plays from scrimmage – passes, runs, punts, or field goal attempts – or free kicks such as kickoffs and fair catch kicks. Substitutions can be made between downs, which allows for a great deal of specialization as coaches choose the players best suited for each particular situation. During a play, each team should have no more than 11 players on the field, and each of them has specific tasks assigned for that specific play.
In gridiron football, clock management is the manipulation of a game clock and play clock to achieve a desired result, typically near the end of a match. It is analogous to "running out the clock" seen in many sports, and the act of trying to hasten the game's end is often referred to by this term. Clock management strategies are a significant part of American football, where an elaborate set of rules dictates when the game clock stops between downs, and when it continues to run.
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.
Center (C) is a position in gridiron football. The center is the innermost lineman of the offensive line on a football team's offense. The center is also the player who passes the ball between his legs to the quarterback at the start of each play.
A trick play, also known as a gadget play, gimmick play or trickeration, is a play in gridiron football that uses deception and unorthodox tactics to fool the opposing team. A trick play is often risky, offering the potential for a large gain or a touchdown if it is successful, but with the chance of a significant loss of yards or a turnover if not. Trick plays are rarely used not only because of the riskiness, but also to maintain the element of surprise for when they are used.
In American football, a quarterback kneel, also called taking a knee, genuflect offense, kneel-down offense, or victory formation occurs when the quarterback immediately kneels to the ground, ending the play on contact, after receiving the snap. It is primarily used to run the clock down, either at the end of the first half or the game itself, to preserve a lead. Although it generally results in a loss of a yard and uses up a down, it minimizes the risk of a fumble, which would give the other team a chance at recovering the ball.
Street football, also known as backyard football or sandlot football, is a simplified variant of American football primarily played informally by youth. It features far less equipment and fewer rules than its counterparts, but unlike the similar touch football, features full tackling.
The following terms are used in American football, both conventional and indoor. Some of these terms are also in use in Canadian football; for a list of terms unique to that code, see Glossary of Canadian football.
In gridiron football, a penalty is a sanction called against a team for a violation of the rules, called a foul. Officials initially signal penalties by tossing a bright yellow or orange 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 giving the offense 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.
Offside is a minor foul in gridiron football caused when a defender crosses the line of scrimmage ahead of the snap of the ball. The penalty associated with the infraction is the advancing of the ball five yards and a replay of the down.
In gridiron football, a punt is a kick performed by dropping the ball from the hands and then kicking the ball before it hits the ground. The most common use of this tactic is to punt the ball downfield to the opposing team, usually on the final down, with the hope of giving the receiving team a field position that is more advantageous to the kicking team when possession changes. The result of a typical punt, barring any penalties or extraordinary circumstances, is a first down for the receiving team. A punt is not to be confused with a drop kick, a kick after the ball hits the ground, now rare in both American and Canadian football.
