In gridiron football, a turnover occurs when the team with the ball loses possession of the ball without kicking or punting it, which is then gained by the other team. In American football, the two events that are officially classified as "turnovers" are fumbles (accidental loss of a live ball after a player has possession) [1] and interceptions (passes intended for a member of the passing team, but caught by a member of the defending team).

In addition, the term "turnover" is often used to refer to a turnover on downs, when a team attempts to gain a first down, touchdown or field goal on a fourth down play (known as a fourth down conversion), but is unsuccessful. When this occurs, the opposing team automatically gains possession at the spot to which the ball was advanced at the end of the play, unless a penalty has occurred (every defensive penalty, if accepted, results either in an automatic first down or a replay of down). In this event, the team that has lost possession is not permitted an opportunity to advance the ball any further.

A play that results in a turnover is rare in gridiron football as only less than 3% of passes in the NFL result in interceptions and less than 1% of run plays in the NFL end in a fumble recovered by the defense. It can have a major effect on the outcome of the game, though, ending an offense's momentum, as it ends their drive without a score and often results in the other team having better field position compared to a punt or a kickoff return following a score. [2] One multiseason analysis of NFL games by Harvard University in 2014 found that teams with a positive turnover differential of one in a game ultimately won 69.6% of the time. Whereas a team with a positive turnover differential of two in a game won 83.7% of the time and a team with a positive turnover differential of three in a game won 90.7% of the time. [3]

NFL Football

National Football League game statistics recording turnovers only include lost fumbles and intercepted passes; turnovers on downs are not included (e.g., a team whose only turnovers are turnovers on downs is credited with having "no turnovers").

Canadian Football

In Canadian football, turnovers generally occur in a similar manner to American football, except that a turnover on downs will occur after three downs instead of four. In addition, Canadian Football League statistics record turnovers on downs on an equal basis to turnovers caused by fumbles and interceptions.

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 consists of many such plays.

<span class="mw-page-title-main">Touchdown</span> Means of scoring in both American and Canadian football

A touchdown is a scoring play in gridiron football. Scoring a touchdown grants the team that scored it 6 points. Whether running, passing, returning a kickoff or punt, or recovering a turnover, a team scores a touchdown by advancing the football into the opponent's end zone. More specifically, a touchdown is when a player is in possession of the ball, any part of the ball is in the end zone they are attacking, and the player is not down.

<span class="mw-page-title-main">Gridiron football</span> Team sport primarily played in North America

Gridiron football, also known as North American football, or in North America as simply football, is a family of football team sports primarily played in the United States and Canada. American football, which uses 11 players, is the form played in the United States and the best known form of gridiron football worldwide, while Canadian football, which uses 12 players, predominates in Canada. Other derivative varieties include arena football, flag football and amateur games such as touch and street football. Football is played at professional, collegiate, high school, semi-professional, and amateur levels.

<span class="mw-page-title-main">Down (gridiron football)</span> Period in which a play transpires in gridiron football

A down in gridiron football is an attempt by the offensive team to run a play to advance the ball, while the defending team simultaneously attempts to halt their advance. The down is a distinguishing characteristic of the game compared to other codes of football, but is synonymous with the 6 "tackle" rule in rugby league.

In American football, a touchback is a ruling that is made and signaled by an official when the ball becomes dead on or behind a team's own goal line and the opposing team gave the ball the momentum, or impetus, to travel over the goal line, but did not have possession of the ball when it became dead. Since the 2018 season, touchbacks have also been awarded in college football on kickoffs that end in a fair catch by the receiving team between its own 25-yard line and goal line. In the 2023 season, the NFL adopted the same rules as college football in regard to awarding touchbacks on kickoffs that end in a fair catch. In 2024, the NFL moved the placement of the ball after a touchback on a kickoff to the receiving team's 30-yard line; this was part of a radical change to the league's kickoff procedure. Such impetus may be imparted by a kick, pass, fumble, or in certain instances by batting the ball. A touchback is not a play, but a result of events that may occur during a play. A touchback is the opposite of a safety with regard to impetus since a safety is scored when the ball becomes dead in a team's end zone after that team — the team whose end zone it is — caused the ball to cross the goal line.

Gameplay in American football consists of a series of downs, individual plays of short duration, outside of which the ball is or is 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.

<span class="mw-page-title-main">Quarterback kneel</span> American football and Canadian football play

In American football and Canadian football, a quarterback kneel, also called taking a knee, genuflect offense, kneel-down offense, or victory formation, occurs when the quarterback touches a knee to the ground immediately after receiving the snap, thus downing himself and ending the play. 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 or ensure a game goes into overtime if the game is tied and in the fourth quarter. Although it generally results in a loss of some yardage and uses up a down, it minimizes the risk of a fumble, which would give the other team a chance at recovering the ball.

The 1982 San Diego Chargers season was the team's 23rd year, and 13th in the National Football League. The team had a 10–6 record in 1981. 1982 was a strike-shortened season so the league was divided up into two conferences instead of its normal divisional alignment — the Chargers finished 6–3, qualifying for the playoffs as the #5 seed. Their run ended with a second round loss to the Dolphins. This would prove the team's last playoff appearance until 1992.

In gridiron football, a turnover on downs occurs when a team's offense has used all its downs but has not advanced the ball enough to earn another set of downs. The resulting turnover gives possession of the ball to the team on defense.

<span class="mw-page-title-main">Penalty (gridiron football)</span> Penalty in 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.

<span class="mw-page-title-main">Punt (gridiron football)</span> Kick downfield to the opposing team in 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 maximizing the distance the opposing team must advance in order to score. 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.
