Clock management

Last updated October 11, 2023

In gridiron football, clock management is an aspect of game strategy that focuses on the game clock and/or play clock to achieve a desired result, typically near the end of a match. Depending on the game situation, clock management may entail playing in a manner that either slows or quickens the time elapsed from the game clock, to either extend the match or hasten its end. When the desired outcome is to end the match quicker, it is analogous to " running out the clock" (and associated counter-tactics) seen in many sports. 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.

In American football

Rules for the game clock

Upon kickoff, the clock is started when a member of the receiving team touches the ball, or, if the member of the receiving team touches the ball in their end zone, carries the ball out of the end zone. The clock is stopped when the down ends. (The clock never starts if the receiving team downs the ball in their own end zone for a touchback.) The clock is then restarted when the offense snaps the ball for their first play and continues to run unless one of the following occurs, in which case the clock is stopped at the end of the play and restarts at the next snap unless otherwise provided:^[1]

A player carrying the ball goes out of bounds. The clock stops in all 4 quarters and, for most of the game, it is restarted upon the referee spotting the ball and blowing the whistle to signal the resumption of play. In college football, the clock restarts upon the snap of the ball when the clock was stopped with less than 2:00 left in either half. The NFL rule is the same as in the college game for the first half of games, but the clock restarts upon the snap when there is under 5:00 left in the 4th quarter. In high school football, the clock starts on the snap the entire game.
A loose ball is out of bounds. The clock is restarted when a ball is returned to the field in the NFL. In NFHS and NCAA rules, this is the same as when the ball is carried out of bounds, although under NCAA rules, the clock starts^{[ when? ]} after a forward fumble the entire game.
A forward pass is ruled incomplete.
Either team calls for a timeout.
An official calls for a timeout, perhaps because a player is injured or there is a penalty on the play. Officials will restart the clock after an official timeout has concluded unless another of the conditions applies. In the NFL, if the timeout is for a penalty enforcement after the 2-minute warning of the first half or inside the last 5 minutes of the second half/overtime (absent special timing rules for specific fouls), the clock starts on the snap.
- 10 seconds will be taken off the clock, and the clock started when the ball is spotted, if the offense, after the 2-minute warning of either half, fouls or commits certain other acts that cause the clock to stop (including an injury when the offense is out of timeouts, except under certain circumstances), unless the clock will stop anyway for a different reason. In Canadian football, the offense may execute one additional untimed play if the clock expires while the ball is not in play.
A score or touchback occurs. Additionally, the clock does not run during or after a conversion attempt.
Possession of the football is transferred between teams for any reason.
In high school and college football, the clock is briefly stopped when a team earns a first down to allow the chain crew to reposition themselves. The NFL has no such stoppage.

If the clock runs out during a play, the current play is allowed to continue to its conclusion. If the clock runs out between downs, the period ends in American football, but in Canadian football the offense is allowed one last down.

Each team is given three timeouts per half which they can use to stop the clock from running after a play. In the NFL, teams get two timeouts in a preseason or regular season overtime period, or three in a postseason overtime half.

On a fair-catch kick in the NFL, the clock starts at the kick and stops at the end of the play.

Strategies

Strategies for leading teams on offense

A team on offense that has the higher score seeks to use as much time as possible. A drive may therefore benefit the team, even if it scores no points, by taking time off the clock. The team may:

Favor run plays over pass plays.
Use the center of the field rather than the sidelines to avoid going out of bounds and stopping the clock.
Delay the start of each play until the play clock approaches 0.

The team may use counterintuitive game plans, such as declining to score or allowing the opponents to score, to accelerate the end of the game.

If the defense does not have enough time-outs to stop the clock before the ball is turned over on downs, the offense can run out the clock by executing repeated quarterback kneels until the clock runs out. In the NFL and college football, up to 40 seconds can be taken off the clock between plays. The NFL also has a built-in two-minute warning that stops the clock after the play that occurs when the clock hits two minutes ends. In order to successfully run out the clock by kneeling, there must be less than 40 seconds on the clock if the opponent has two time-outs, 1 minute 20 seconds if the opponent has one time-out, or 2 minutes if the defense has no time-outs remaining, at the snap on a first down (an additional 40 seconds can be run off if the clock keeps running after the play that gains the first down). The offense can burn further time off the clock by timewasting: keeping the ball live (and the clock running) simply by keeping away from any defensive player, regardless of position on the field.

Strategies for trailing teams on offense

A team on offense that has the lower score seeks to conserve time. The team may:

Use a no-huddle offense; forgo detailed design of a play and instead signal and initiate a play quickly.
Have the quarterback "spike" the ball, sacrificing a down to stop the clock. (An explicit exception is written into the American football rule books so that the move is not penalized for intentional grounding nor ruled a fumble, so long as he spikes the ball immediately after the snap from the center.)
Use a passing play and/or attempt to get the ball carrier near the sidelines so that the ball carrier can go out of bounds before being tackled. (Taking the ball out of bounds and incomplete passes both stop the clock.)
If a play ends such that the game clock continues running, use a timeout.
If the ball is still alive while the clock runs out and the team with the ball is still trailing, do everything within the team's power to keep the ball alive until it can be advanced to the end zone. Often this incorporates a series of lateral and backward passes to avoid the ball carrier being tackled and the game ending.

A team that is tied or trailing by one or two points but is within the red zone (and thus in easy field goal range) seeks to burn a specific amount of time off the clock, such that they can stop the clock with five or fewer seconds on the clock, so that their placekicker can kick a field goal with no time remaining and win the game.

One exceptionally rare strategy that a team in possession of the ball near the end of the game can use is the fair catch kick. For the fair catch kick to be a viable option, several conditions must be met: the opposing team must have punted the ball within play and the receiving team used the fair catch to secure the ball, the punt must have been exceptionally short so that the spot of the fair catch is within field goal range and unlikely to be returned, the team using the fair catch kick must be either tied or within three points, and the game must not be played under NCAA rules (the NCAA has no fair catch kick rule).

Strategies for the defense

A team on defense has little control over the pace of the game. It may expend its timeouts to ensure that there is adequate time left on the clock, in case the team regains possession. The defense can make decisions on how to stop the ball carrier based on whether the team is trailing or leading: if the offense is trying to conserve time, the defense can foil that by tackling the ball carrier in-bounds before they can get out of bounds. Defenses likewise can safely devote more personnel to the perimeter and leave the center of the field and areas near the line of scrimmage less defended, as an offense that cannot afford to keep the clock running will have to throw toward the sidelines (see also: prevent defense).

Various rules ensure that the defense cannot deliberately commit fouls to manipulate the game clock, and in the most extreme such cases, an unfair act can be declared and the game forfeited to the offense. (Likewise, if the offense commits fouls to burn off time and get extra downs, the clock is reset and unsportsmanlike conduct is called on them.)

Canadian football

In Canadian football, a team trailing by one point or tied has an additional option: a ball can be kicked from anywhere on the field in that sport, and balls kicked into or through the end zone and not returned score a single point. This allows a team trailing by one to advance the ball upfield, then punt the ball toward the end zone in hopes of tying the game for one point (the player could also drop kick the ball, which would allow the kicking team to win on a field goal if kicked through the uprights). To prevent this scenario, defending teams will place their punter in the end zone to retrieve the ball and kick it back out of the end zone, preventing that single point from being scored.

Several of the strategies discussed above for American football above can be used in the Canadian code, however rule differences mean that running out the clock much more difficult:

Teams are allowed only three downs to advance the ball 10 yards without losing possession (as opposed to four in the American game).
The offensive team has only 20 seconds after the ball is whistled into play to start a new play (as opposed to 25 seconds in American high school football and 40 seconds from the end of the last play in college football and the NFL).
Prior to the three-minute warning in Canadian football, when the ball is snapped, the clock starts on the ready for play.
After the three-minute warning in Canadian football, two key timing changes occur:
- The clock stops after every play. The clock restarts when the referee whistles the ball in play after a tackle in bounds, and with the snap after an incomplete pass or a tackle out of bounds.
- A "time count" (the same foul as "delay of game" in American football), which is a 5-yard penalty (with the down repeated) at other points in the game, becomes a loss of down penalty on first or second down and a 10-yard penalty on third down. Additionally, if the referee deems a time count violation on third down in the last three minutes of a half to be deliberate, he can require the offensive team to legally place the ball in play within the 20-second count, with a violation resulting in loss of possession.^[2]
If the clock hits 0:00 between plays, Canadian teams are required to execute one final play, even if the ball has not yet been snapped. In the American game, if the clock hits 0:00 between plays, the game is over unless the previous play ended in a defensive penalty, a score, or circumstances warranting various types of kicks.

These differences make for radically different endgames if the team with the lead has the ball. In the NFL, a team can run 120 seconds (2 minutes)--and slightly more in the NCAA--off the clock without gaining a first down (assuming that the defensive team is out of timeouts). In the Canadian game, just over 40 seconds can be run off. The Canadian Football League is proud of this distinction, with "No Lead Is Safe" being one of the league's catchphrases.^[3]

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.

<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.

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 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.

American and Canadian football are gridiron codes of football that are very similar; both have their origins partly in rugby football, but some key differences exist between the two codes.

United Indoor Football (UIF) was an indoor football league in the United States that operated from 2005 to 2008. Ten owners from the National Indoor Football League, including one expansion and two from arenafootball2 (af2) took their franchises and formed their own league. The league was based in Omaha, Nebraska.

In sports, a time-out or timeout is a halt in the play. This allows the coaches of either team to communicate with the team, e.g., to determine strategy or inspire morale, as well as to stop the game clock. Time-outs are usually called by coaches or players, although for some sports, TV timeouts are called to allow media to air commercial breaks. Teams usually call timeouts at strategically important points in the match, or to avoid the team being called for a delay of game-type violation, such as the five-second rule in basketball.

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.

A kickoff is a method of starting a drive in gridiron football. Additionally, it may refer to a kickoff time, the scheduled time of the first kickoff of a game. 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.

In sports strategy, running out the clock is the practice of a winning team allowing the clock to expire through a series of preselected plays, either to preserve a lead or hasten the end of a one-sided contest. Such measures expend time but do not otherwise have a tactical purpose. This is usually done by a team that is winning by a slim margin near the end of a game, in order to reduce the time available for the opposing team to score. Generally, it is the opposite strategy of running up the score.

<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. 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.

In most levels of professional American football, the two-minute warning is a suspension of play that occurs when two minutes remain on the game clock in each half of a game, i.e., near the end of the second and fourth quarters, and overtime. Its effect on play is similar to that of a timeout: the game clock stops and the teams gather to discuss strategy. The suspension of play is two minutes long, the same as the short two-minute intermissions between quarters within each half. Its name reflects its origins as a point in the game where the officials would inform the teams that the half was nearly over, as the official game clock was not displayed in the stadium at the time the two-minute warning was created.

In Canadian football, the three-minute warning is given when three minutes of game time remain on the game clock in the first and second halves of a game. The three-minute warning stops the game clock in all cases. American football has a two-minute warning.

A comparison between American football and rugby league is possible because of their shared origins and similar game concepts. Rugby league is arguably the most similar sport to American football after Canadian football: both sports involve the concept of a limited number of downs/tackles and scoring touchdowns/tries takes clear precedence over goal-kicking.

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 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 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.

In gridiron football, replay review is a method of reviewing a play using cameras at various angles to determine the accuracy of the initial call of the officials. An instant replay can take place in the event of a close or otherwise controversial call, either at the request of a team's head coach or the officials themselves.

In gridiron football, a spike of the ball is a play in which the quarterback intentionally throws the ball at the ground immediately after the snap. Officially an incomplete pass, a spike play stops the clock at the cost of exhausting a down without any gain or loss in yardage. It is principally used when a team is conducting a hurried drive late in a half, and the game clock is running after the previous play. Stopping the clock – particularly when the offense has no timeouts remaining or wishes to conserve timeouts – typically allows the offense more time to plan their next play without losing scarce game clock time.

<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 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.
