Icing the kicker

Last updated

In the sports of American football or Canadian football, the act of icing the kicker or freezing the kicker is the act of calling a timeout immediately prior to the snap in order to disrupt the process of kicking a field goal. The intent is to throw the kicker off of his routine and force him to feel pressure for a longer amount of time. The tactic is used at the collegiate and professional levels, although its effectiveness has not been proven.



In order to ice a kicker, either a player or a coach on the defending team will call a timeout just as the kicker is about to attempt a game-tying or game-winning field goal. This is intended to either stop the kick immediately as the kicker is mentally prepared, or allow for the kicker to kick immediately after the timeout so that the initial kick does not count, in an attempt to mentally disrupt the kicker for the actual kick. If the tactic is successful, the kicker will miss the kick due to choking. Should the kicker make the subsequent kick, then the attempt to ice the kicker is considered unsuccessful.

In the NFL, only one timeout can be called between the same two plays. In contrast, repeated icing in collegiate football is legal. [1]

One variant of this tactic, attributed to former Denver Broncos coach Mike Shanahan, [2] is to call time out from the sidelines just before the ball is snapped. This prevents the kicking team from realizing the kick will not count until after the play is over. However, this has the potential to backfire: the invalid first kick could miss or be blocked, only to be followed by a successful second kick.


A study was undertaken by Scott Berry, a statistician and the former chairman of the Statistics in Sports section of the American Statistical Association, and Craig Wood, a biostatistician, life-long Pittsburgh Steeler fan, who won the Inaugural Henry Hood Center for Health Research Pillar Award, was published in 2004 in the journal Chance. [3] Berry and Wood looked at every field-goal attempt made in the 2002 and 2003 NFL seasons, including playoffs, and concluded that, for "pressure kicks" those made with 3 minutes or less remaining in the game or overtime period which would tie the game or put the kicking team in the lead in the 40–55 yard range, icing the kicker caused the percentage of successful attempts to drop by about ten percent for an average kicker on a sunny day. On shorter kicks, the effect was found to be negligible. [2] [4] [5] However, the statistical significance of the difference found which amounted to four kicks out of 39 attempts has been questioned, [6] and an examination by Nick Stamms of STATS, Inc. found that "pressure kicks" (defined as above except within two minutes, not three) in the NFL regular season from 1991 to 2005 showed an insignificant difference between non-iced kicks (457 out of 637, or 71.7%) and iced kicks (152 out of 211, or 72.0%). [7]

In other sports

A similar tactic is also common in basketball, known as icing the shooter. A team may call a timeout just before the opposing team's free-throw shooter is given the ball on the final free throw, in an attempt to disrupt the shooter, typically if a missed free throw allows for the calling team to either have a chance to win the game with a successful field goal, or allows the calling team to preserve a lead.

A penalty kick is a method of restarting play in association football, in which a player is allowed to take a single shot at the goal while it is defended only by the opposing team's goalkeeper. It is awarded when an offence punishable by a direct free kick is committed by a player in their own penalty area. The shot is taken from the penalty mark, which is 11 m from the goal line and centred between the touch lines.

<span class="mw-page-title-main">Onside kick</span> Short kickoff in gridiron football to try to keep possession of the ball

In gridiron football, an onside kick is a kickoff deliberately kicked short in an attempt by the kicking team to regain possession of the ball. This is in contrast with a typical kickoff, in which the kicking team intends to give the ball to the other team and thus kicks the ball far downfield in order to maximize the distance the receiving team has to advance the ball in order to score. The risk to the team attempting an onside kick is that if it is unsuccessful and the receiving team gets the ball, the receiving team usually has a much better field position than it might have with a normal kickoff. Rules and procedures for onside kicks differ between the different codes and leagues of gridiron football.

Gamesmanship is the use of dubious methods to win or gain a serious advantage in a game or sport. It has been described as "Pushing the rules to the limit without getting caught, using whatever dubious methods possible to achieve the desired end". It may be inferred that the term derives from the idea of playing for the game as opposed to sportsmanship, which derives from the idea of playing for sport. The term was popularized by Stephen Potter's humorous 1947 book, The Theory and Practice of Gamesmanship . It had, however, been used before by Ian Coster in his autobiographic book Friends in Aspic, published in 1939, where it was attributed to Francis Meynell.

<span class="mw-page-title-main">Time-out (sport)</span> Intentional delay in sports

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.

<span class="mw-page-title-main">American football rules</span>

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 sports, 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">Field goal</span> Means of scoring in gridiron football

A field goal (FG) is a means of scoring in gridiron football. To score a field goal, the team in possession of the ball must place kick, or drop kick, the ball through the goal, i.e., between the uprights and over the crossbar. American football requires that a field goal must only come during a play from scrimmage while Canadian football retains open field kicks and thus field goals may be scored at any time from anywhere on the field and by any player. The vast majority of field goals, in both codes, are place kicked. Drop kicked field goals were common in the early days of gridiron football but are almost never done in modern times. In most leagues, a successful field goal awards three points.

<span class="mw-page-title-main">Two-point conversion</span> Play in American and Canadian football

In gridiron football, a two-point conversion or two-point convert is a play a team attempts instead of kicking a one-point conversion immediately after it scores a touchdown. In a two-point conversion attempt, the team that just scored must run a play from scrimmage close to the opponent's goal line and advance the ball across the goal line in the same manner as if they were scoring a touchdown. If the team succeeds, it earns two additional points on top of the six points for the touchdown, for a total of eight points. If the team fails, no additional points are scored. In either case, if any time remains in the half, the team proceeds to a kickoff.

Field goal range is the part of the field in American football where there is a good chance that a field goal attempt will be successful.
