The game is tied. Five seconds left. The kicker jogs out for the game-winning field goal — and that’s usually when icing the kicker comes into play. He sets his feet, the crowd goes silent, and right as the snap is about to happen, the opposing coach calls timeout.
That’s icing the kicker. It’s one of football’s most debated tactics, and it happens in nearly every close game with a field goal on the line. This guide covers exactly what icing the kicker means, where the term came from, and what the data actually says about whether it works.
Quick Answer: What Is Icing the Kicker?
Icing the kicker is when the defensive team calls a timeout right before the snap on a field goal attempt, usually late in a close game. The goal is to disrupt the kicker’s rhythm and routine, forcing him to wait and think about the kick longer than he normally would, in hopes that the extra pressure causes a miss.
The kick still happens after the timeout, but it doesn’t count. The kicker essentially gets a free practice attempt, then has to do it again for real.
How Coaches Actually Ice a Kicker
Timing is everything. A coach who calls timeout too early just gives the kicker extra time to relax and reset. The tactic only works, in theory, if the timeout comes at the very last possible second, right as the ball is about to be snapped.
Some coaches have taken this a step further by deliberately waiting to signal the referee until the absolute last moment, so the kicking team doesn’t realize the timeout is coming until the play has already happened. That means the kicker sometimes goes through the entire motion of the kick, watches it sail through the uprights, celebrates, and only then finds out it didn’t count.
Where Did the Term Come From?
The tactic itself is old, but it became a household term thanks to one very specific rule change and one very specific coach.
Before 2004, only players on the field could call a timeout, not coaches from the sideline. That meant icing a kicker required a defensive player to notice the field goal unit setting up and call timeout in real time, which didn’t leave much room for perfect timing.
In 2004, the NFL changed that rule. Coaches could now call a timeout directly from the sideline. That single change opened the door for a far more calculated version of the tactic.
Denver Broncos head coach Mike Shanahan is widely credited with popularizing the modern version of icing the kicker. In Week 2 of the 2007 season, Shanahan called a timeout just before Oakland Raiders kicker Sebastian Janikowski attempted a 52-yard field goal. Janikowski made the initial kick. It didn’t count. On the second attempt, after the ice, he missed. The moment got national attention, and coaches around the league started using the same approach far more often.
Does Icing the Kicker Actually Work?
This is where things get genuinely messy, because researchers have been arguing about it for two decades, and the data doesn’t point in one clean direction.
The case that it doesn’t work: A widely cited study published in the journal Chance looked at every field goal attempt during the 2002 and 2003 NFL seasons. A separate analysis by STATS Inc., covering pressure kicks from 1991 to 2005, found non-iced attempts succeeded 71.7% of the time compared to 72.0% for iced attempts, a difference so small it isn’t statistically meaningful. Multiple later academic studies have reached similar conclusions: once you control for kick distance and game situation, icing barely moves the needle.
The case that it does work, at least sometimes: Other research tells a different story. One analysis of NFL data found that in game-critical situations, kickers succeeded 76% of the time overall, but succeeded only 77% when iced versus 82% in low-pressure situations, suggesting pressure itself matters more than the ice specifically. A separate breakdown from Sharp Football Analysis found that over a recent four-season stretch, iced kicks in clutch situations had a lower success rate than non-iced clutch kicks in every single year, with the gap averaging 12.8 percentage points.
The distance matters more than almost anything else. Nearly every study agrees on one point: icing seems to have little to no effect on short kicks, but starts showing a real, measurable impact once the distance passes somewhere around 33 to 34 yards. Kicks under 30 yards are considered close to automatic regardless of any timeout, which makes sense, since a kicker’s margin for error shrinks dramatically as the distance grows.
Selection bias muddies everything. Here’s the catch that makes this debate so hard to settle. Coaches don’t call timeouts randomly. They ice kickers specifically in the hardest, highest-pressure situations, which are exactly the kicks most likely to be missed anyway, ice or no ice. That means raw success-rate comparisons can make icing look more effective than it actually is, since the iced kicks were already the tougher attempts to begin with.
So What’s the Real Answer?
The honest answer is that the evidence is genuinely split, and even researchers who study this professionally disagree with each other. Multiple rigorous statistical studies have found no meaningful effect. Other analyses, using different date ranges and different definitions of “pressure,” have found a real, if modest, drop in success rate. Even ESPN once published an analysis arguing icing has the opposite effect, making kickers marginally more accurate, not less.
If there’s a consensus at all, it’s a narrow one: icing probably has little to no effect on short, routine kicks, and might have a small, hard-to-isolate effect on longer, high-pressure attempts. Beyond that, most researchers who’ve dug into the numbers describe the tactic as somewhere between a minor psychological factor and pure football folklore.
Why Coaches Keep Doing It Anyway
If the data is this uncertain, why does nearly every coach still ice the kicker in a close game?
Part of it is simple risk management. If a coach doesn’t call the timeout and the kicker makes the field goal, that coach faces immediate criticism for not trying “everything.” If a coach does call the timeout and the kicker still makes it, nobody blames the coach, since the tactic is expected. The downside of not icing feels much larger than the downside of icing and having it not work, even if the actual statistical impact is close to zero either way.
There’s also a simpler explanation: coaches have unlimited timeouts to burn in that exact situation anyway, since the game is often already over after the kick either way. Calling timeout costs a coach essentially nothing at that point in the game, so even a small, unproven chance of forcing a miss is worth taking.
The Rules Around Icing the Kicker
In the NFL, a team can only call one timeout between the same two plays, meaning a coach can’t repeatedly ice the same kicker on the same play over and over. College football works differently. Under NCAA rules, a team can call multiple timeouts back to back on the same field goal attempt, as long as they still have timeouts remaining, which has occasionally led to a kicker facing two or even three separate ice attempts before a single kick actually counts.
Frequently Asked Questions
What does it mean to ice the kicker?
It means calling a timeout right before the snap on a field goal attempt, usually late in a close game, to disrupt the kicker’s rhythm and add extra mental pressure before the real attempt.
Who popularized icing the kicker in the NFL?
Denver Broncos coach Mike Shanahan is widely credited with popularizing the modern tactic, notably icing Raiders kicker Sebastian Janikowski in a 2007 game.
When did coaches start being allowed to call timeouts for icing?
The NFL changed its rules in 2004 to allow coaches to call timeouts directly from the sideline, which made precisely timed icing attempts possible for the first time.
Does icing the kicker actually work?
The data is mixed. Most large statistical studies find little to no meaningful effect, especially on shorter kicks, though some research suggests a modest effect on longer, high-pressure attempts.
Can a team ice a kicker more than once on the same kick?
In the NFL, no, teams are limited to one timeout between the same two plays. In college football, teams can ice a kicker multiple times in a row if they have enough timeouts remaining.
Does the distance of the kick matter for icing to be effective?
Yes. Most research agrees that icing has little impact on kicks under 30 yards, with any measurable effect showing up mainly on longer attempts past roughly 33 to 34 yards.
Conclusion
Icing the kicker sits in a strange spot in football: a tactic nearly every coach uses, based on evidence that still isn’t settled after two decades of study. Some of the smartest sports statisticians in the country have looked at the same basic question and walked away with different answers. Until that changes, expect to keep seeing that same scene: kicker set, crowd silent, and a timeout called right at the last possible second.
