List Of Gridiron Football Rules
The following is a description of the various and alternating rules of gridiron football. Numerous leagues or organizations tend to send a laundry list of rules in order to better distinguish themselves from their counterparts. American football (general) Field and players American football is played on a football field that is . The longer boundary lines are ''sidelines'', while the shorter boundary lines are ''end lines''. Sidelines and end lines are out of bounds. Near each end of the field is a ''goal line''; they are apart. A scoring area called an ''end zone'' extends beyond each goal line to each end line. The end zone includes the goal line but not the end line. While the playing field is effectively flat, it is common for a field to be built with a slight crown—with the middle of the field higher than the sides—to allow water to drain from the field. ''Yard lines'' cross the field every , and are numbered every 10 yards from each goal line to the 50-yard line, or m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Snap (American Football)
A snap (colloquially called a "hike", "snapback", or "pass from center") is the backward passing of the ball in gridiron football at the start of play from scrimmage. Action The ball begins on the ground with its long axis parallel to the sidelines of the field, its ends marking each team's line of scrimmage in American football; in Canadian football, the line of scrimmage of the team without the ball is 1 yard past their side of the ball. The player snapping the ball (known officially as the "snapper" in rule books) delivers the ball to another player, and that action is the snap. The snapper may hand, throw, or even roll the ball to the other player. The snap must be a quick and continuous movement of the ball by one or both hands of the snapper, and the ball must leave the snapper's hands. The various rules codes have additional requirements, all of which have the effect of requiring the ball to go backward. The snapper almost always passes the ball between his legs, but on ...

Punt (gridiron Football)
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. The type of punt leads to different motion of the football. Alex Moffat invented the now-common spiral punt, as opposed to end-over-end. Description A punt in gridiron football is a kick performed by dropping the ball from the hands and then kicking the ball before it hits the ground. In football, the offense has a limited number of downs, or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kickoff (American Football)
A kickoff is a method of starting a drive in gridiron football. Typically, a kickoff consists of one team – the "kicking team" – kicking the ball to the opposing team – the "receiving team". The receiving team is then entitled to ''return'' the ball, i.e., attempt to advance it towards the kicking team's end zone, until the player with the ball is tackled by the kicking team, goes out of bounds, scores a touchdown, or the play is otherwise ruled dead. Kickoffs take place at the start of each half of play, the beginning of overtime in some overtime formats, and after scoring plays. Common variants on the typical kickoff format include the onside kick, in which the kicking team attempts to regain possession of the ball; a touchback, which may occur if the ball is kicked into the receiving team's end zone; or a fair catch, in which a player on the receiving team asks to catch the ball without interference from the kicking team, waiving his entitlement to attempt a return rush ...

Turnover On Downs
In gridiron football, a turnover on downs occurs when a team's offense has used all their downs but has not progressed downfield enough to earn another set of downs. The resulting turnover gives possession of the ball to the team currently on defense. In American football, both indoor and outdoor, a team has four opportunities (each opportunity is called a "down") to gain at least ten yards or to score. Any ground gained during each down short of these ten yards is kept for the next chance, and any ground lost must be regained in addition to the ten yards. Thus, if a team gains four yards on first down, it then has three chances to gain the six remaining yards, and if a team loses four yards on first down then it must gain a total of fourteen yards over the next three chances. If a team gains the required ten yards, it receives another four downs to gain another ten yards (an event called a "first down") or cross the goal line for a score. The same principles apply in Canadian fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Football Play
A play from scrimmage is the sequence in the game of gridiron football during which one team tries to advance the ball, get a first down, or score, and the other team tries to stop them or take the ball away. Once a play is over, and before the next play starts, the football is considered dead. A game of American football (or Canadian Football) consists of many (about 120–150) such plays. Specifications The term is also used to denote a specific plan of action, or its execution, under a particular set of circumstances faced by either team.Shields, Patricia and Rangarajan, Nandhini. 2013''A Playbook for Research Methods: Integrating Conceptual Frameworks and Project Management''Stillwater, OK: New Forums Press, p. 1. For instance, the offensive team may be faced with one or two downs left in a possession and still ten or more yards to go to earn a new set of downs. In this instance, they may decide to employ a forward pass. Well in advance of the particular game, a number o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incomplete Pass
An incomplete pass is a term in gridiron football which means that a legal forward pass is not successfully caught by an eligible offensive player within the field of play. An incomplete pass can occur if (1) the ball hits the ground in the field of play before a player on either team gains possession; (2) the ball is caught by a player on either team who, at the moment of possession is out of bounds; or (3) the ball is thrown outside the field of play. An incomplete pass causes the down to advance by one and the offensive team gains no yards. The game clock is stopped. Becoming a fumble or interception If the receiver catches the ball and has possession of it, then loses control of it for any reason and a player from the other team catches it a fumble is called. In the NFL, both feet must be in bounds and the player must have clear control of the ball and make a football move or have the ability to perform such an act. In other leagues, only one foot must be in bounds with clea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Out Of Bounds
In sports, out of bounds (or out-of-bounds) refers to being outside the playing boundaries of the field. Due to the chaotic nature of play, it is normal in many sports for players and/or the ball to go out of bounds frequently during a game. The legality of going out of bounds (intentionally or not), and the ease of prevention, vary by sport. In some cases, players may intentionally go or send the ball out of bounds when it is to their advantage. Baseball In baseball, there are two ways for a batted ball to be out-of-bounds. One is to exit the field of play between the foul lines (the foul lines themselves are fair territory). If this is achieved without touching the ground first, it is a home run, and the batter and teammates who are on base run to home plate and score a point for their team. If the ball bounced off the ground before exiting play, it is a ground rule double, and the batter and all runners not on third advance exactly two bases; runners only score if they were ...

Official (American Football)
In gridiron football, an official is a person who has responsibility in enforcing the rules and maintaining the order of the game. During professional and most college football games, seven officials operate on the field. Since 2015, Division I college football conferences have used eight game officials, the Alliance of American Football (AAF) in its only season in 2019 and the 2020 version of the XFL have used eight game officials. College games outside the Division I level use six or seven officials. Arena football, high school football, and other levels of football have other officiating systems, which use less than the standard seven officials. High school football played under the National Federation of State High School Associations (NFHS) rules typically use five officials for varsity and 3, 4, or 5 for non-varsity games. Football officials are commonly, but incorrectly, referred to collectively as referees, but each position has specific duties and a specific name: Co ...

Tackle (football Move)
Most forms of football have a move known as a tackle. The primary purposes of tackling are to dispossess an opponent of the ball, to stop the player from gaining ground towards goal or to stop them from carrying out what they intend. The word is used in some contact variations of football to describe the act of physically holding or wrestling a player to the ground. In others, it simply describes one or more methods of contesting for possession of the ball. It can therefore be used as both a defensive or attacking move. Name origin In Middle Dutch, the verb meant to grab or to handle. By the 14th century, this had come to be used for the equipment used for fishing, referring to the rod and reel, etc., and also for that used in sailing, referring to rigging, equipment, or gear used on ships. By the 18th century, a similar use was applied to harnesses or equipment used with horses. Modern use in football comes from the earlier sport of rugby, where the word was used in the 19th ...

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 ...

Rush (gridiron Football)
Rushing is an action taken by the offense that means to advance the ball by running with it, as opposed to passing, or kicking. Running Rushing, on offense, is running with the ball when starting from behind the line of scrimmage with an intent of gaining yardage. While this usually means a running play, any offensive play that does not involve a forward pass is a rush - also called a run. It is usually done by the running back after a handoff from the quarterback, although quarterbacks and wide receivers can also rush. The quarterback will usually run when a passing play has broken down – such as when there is no receiver open to catch the ball – and there is room to run down the field. A team with a quarterback who is fast and skilled at running may regularly call intentional running plays for that quarterback, but this is rare due to the increased risk of injury. A wide receiver can act as a rusher on several kinds of plays, such as on a reverse, on an end-around, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
