Red Zone Defense

Inside the 20-yard line the field shrinks and the defense gains an ally in the end line. See how coverages, pressure and run fits change when the goal is to hold a team to three.

A defense can play well for fifty yards and still lose the game in the last twenty. The final stretch of the field, the one between the offense and the end zone, is where drives either end in points or end without them. Coaches talk about it constantly, and the way they defend it is noticeably different from the way they defend the rest of the field.

The area inside the opponent's 20-yard line is called the red zone. The label is not an official part of the rules; it is shorthand used by coaches, broadcasters and statisticians for the stretch where an offense is close enough to score a touchdown or a field goal on most drives. How a defense plays there is a distinct subject, with its own coverages, its own priorities and its own measures of success.

This article explains how the shrinking field changes the game, what defenses do about it, how they defend both the pass and the run, and what to watch for when a team is stopped inside the 20.

What the red zone is

The red zone runs from the 20-yard line to the goal line. Coaches often divide it further into a high red zone, roughly from the 20 down to the 10, and a low red zone or tight red zone inside the 10, though the exact boundaries differ among teams. The area very close to the goal line, inside the 5 or so, is often called the goal line, and it has its own set of tactics, covered in goal-line offense and fourth-and-short from the offensive side.

Two things matter about this part of the field.

Field goals become likely. Once an offense reaches the red zone, it is usually within range of a field goal. Even a failed drive may produce three points.
The end zone is close. A pass completed in the end zone scores six points, so short, quick plays can be enough.

Both facts shape what a defense is trying to accomplish.

The goal changes: from stopping yards to stopping touchdowns

Outside the red zone, a defense wants to stop the offense from gaining yards and picking up first downs. In the red zone, the defense usually accepts that it may not stop the offense from advancing; its goal is to hold the offense to a field goal, or better, to a turnover or a missed kick.

That sounds like a small shift, but it changes decisions. A defense that gives up three points rather than seven is better off by four, and a defense that forces a punt or turnover is better off by much more. Coaches describe this as the difference between bending and breaking: the defense can bend (give up yards and a field goal) as long as it does not break (give up a touchdown).

Statisticians track this as red zone efficiency: the share of an offense's trips inside the 20 that end in a touchdown. The inverse describes the defense. These figures are useful, but they can also move around a lot over a small number of games, because a team may only have a few red zone trips in a game. Treat a single season's figure with some caution, and check current team data on the teams page and the leaders page rather than relying on a number remembered from a broadcast.

How the field helps the defense

The shrinking field is a gift to the defense in a few specific ways.

There is less room behind the defenders. In the middle of the field, a defender has to worry about being beaten deep. In the red zone, the end line is an extra defender: the deepest a receiver can go is the back of the end zone, which is only a few yards away.
Deep routes disappear. The long bomb and the deep post are not available when the offense is 12 yards from the goal line.
The sidelines get closer. The offense has fewer places to throw and fewer places to run.
Time to throw is short. A pass needs only a few yards, so offenses throw quickly, but that also means receivers cannot spread out wide.
Plays gain fewer yards. Runs and catches inside the 10 have only a few yards of room before the goal line or the end line, so a tackle often comes quickly.

This is why offenses find red zone scoring hard even when they move the ball well in the middle of the field. It is a common experience for a team to dominate the field and still settle for field goals.

What defenses change in coverage

The most visible difference is in how defenders cover receivers.

More man coverage

Because there is less room behind the defenders, man coverage is safer in the red zone. A cornerback who is beaten has less distance to give up, and a safety does not have to cover a huge area. Coordinators often call more man-to-man in the red zone, including press technique near the goal line. See press coverage and bump-and-run for how that technique works.

Man coverage also helps against rub routes and picks, and it allows the defense to put a defender on every receiver without leaving a gap, which matters when the offense might line up with several receivers bunched together.

Compressed zone

Zone coverage works differently in the red zone. With little depth, the deep thirds or halves shrink, and defenders can be closer together. Zones become tight, and a receiver who catches the ball in a gap has less room to run. A defense that plays zone is trying to give the quarterback no open spots in a small space.

Some teams are cautious about zone near the goal line because the space between defenders is small but a receiver only needs a few feet. A pass thrown into a tight window against a zone defense is risky for the quarterback, but a defender who is out of position by a step can allow a touchdown.

Two-man and bracket calls

Variations that mix man coverage underneath with safeties deep, called two-man, are a common red zone call because the safeties can help in the end zone while corners and linebackers stay on their men. Coaches also use bracket coverage on a dangerous receiver, with one defender inside and one outside or over the top.

Zero coverage

Near the goal line, some defenses use zero coverage: every defender is in man and nobody is deep. The logic is that the end zone is so close that deep help is of little use, and extra rushers can bother the quarterback. It is a high-risk call, because if the quarterback has time and a receiver beats his man, there is no help. It is typically reserved for situations where a team feels strongly about the matchups.

Defending the routes that work in the red zone

Offenses lean on certain plays in the red zone because they suit the space. Defenders prepare for these plays.

The fade. The quarterback throws a high pass toward the corner of the end zone for a tall receiver to catch. The cornerback's technique is to play with leverage, keep the receiver from running his route cleanly, and turn to find the ball at the last moment. Height and jumping ability matter.
Slants and quick outs. Fast routes designed to get the ball out before the rush arrives. Defenders use press technique to disrupt timing.
Rub and pick plays. Receivers cross paths so that one blocks the defender covering another. Defenders try to avoid contact and switch assignments when needed. The rules about legal contact differ by level; check your league's rulebook.
Bunch and stack formations. Receivers line up close together to complicate man coverage. Defenders are taught to communicate and trade assignments.
Tight end and big-body targets. Large receivers can win jump balls in tight space. Defenders need strong hands and good timing.
Quarterback runs. In a small space, a mobile quarterback is a threat to run for the end zone. A spy or contain defender is often assigned.

Defending the run near the goal line

When an offense gets close, running plays become more common, and the defense changes its personnel accordingly.

Defenses may bring in extra linemen and linebackers in a goal-line package, with more bodies on the field in the area near the line. The aim is to fill every gap, so that the runner has no room to move. This is the same idea described in run fits and gap responsibility, but with more defenders in the box and fewer in coverage.

Goal-line defenses commonly emphasize:

Penetration. Linemen try to get into the backfield and stop the runner before he reaches the line.
Gap integrity. Every gap has a defender; no gap is left for the runner to reach.
Low pad level. Defenders attempt to stay lower than the blockers to win leverage.
Safeties coming up. Deep safeties may move to the line, because there is little to protect behind them.
Tackling the runner before he crosses the goal line. The ball is judged by whether it crosses the plane, so even a runner who is stopped short may fall forward, and defenders aim to hit him before his momentum carries him over.

The result is a front that looks very different from the base defense, with extra large players and little in the secondary except the corners.

Pressure in the red zone

The pass rush matters more inside the 20 for a specific reason: the quarterback has little time to wait for a receiver to run a deep route, but if he is hurried, even a short throw can be tipped or misplaced. Some defenses blitz more often near the goal line because the shorter field means any rusher who gets home forces a quick, bad throw.

But blitzing carries risk. Man coverage with no deep help means a beaten defender gives up a touchdown. And an offense that anticipates the blitz can throw a quick pass to the open area. For more on that trade-off, see the discussions of blitzes and their counters in the articles on pressure packages.

A defense may also use its linemen to get their hands up, since batting a pass down at the line of scrimmage is often as effective as a sack in the red zone.

Penalties and the red zone

Penalties are especially costly inside the 20. Defensive pass interference is the best example. In the NFL, pass interference is a spot foul, which means the ball is placed at the spot of the foul, and a penalty in the end zone puts the ball at the 1-yard line. Other levels of football use different rules, some with a fixed number of yards from the previous spot, so check the rulebook for your level.

A defensive penalty can also give the offense an automatic first down, so a stalled drive keeps going. Defenders therefore have to balance aggressiveness with discipline. A small mistake, such as grabbing a receiver in the end zone, can turn a three-and-out into a touchdown.

Making sense of the clock and the score

The situation matters. A team that is ahead late in a game may be happy to concede a field goal; a team that is behind may need to force a turnover. The distance and the down also change the call. On first down at the 12, the defense may expect either a run or a pass. On third-and-goal from the 3, the offense is likely to pass or run a short-yardage play. The defense picks its call accordingly.

Coaches also consider the kicker. A defense that knows an opponent's kicker is limited may be more willing to hold on third down and force a field-goal attempt from a long distance; but kicking ability varies and should not be assumed.

What the offense is trying to do

It helps to remember the other side of the matchup. The offense tries to create a mismatch, a quick throw, a rub or a run with more blockers than defenders. The tactics are summarized in red zone offense. Seeing the two articles together gives a full picture of why red zone football is a chess match.

Common misconceptions

"The red zone is an official area." It is a convention used by coaches and media.
"The defense always plays tighter coverage in the red zone." Often, but not always. Some teams stay in zone shells.
"A field goal is a defensive failure." A field goal is usually a defensive success compared with a touchdown.
"The goal line is the same as the red zone." The goal-line area is the last few yards, and it calls for a different set of tactics.
"Blitzing is always smart near the goal line." It can be, but man coverage with no deep help raises the risk.

Watching for it

When a team drives into the red zone, listen for the announcers' mention of the formation, and look at the defense. Count the defenders near the line. See whether the cornerbacks are pressed against the receivers and whether the safeties are deep or close. Then watch the first move after the snap. Does the pass rush get home, or does the quarterback throw a quick pass? On running plays, does the defense fill every gap?

You can follow games on the scores page and look up how a team has performed using the teams and leaders pages. If you want to learn the game, the Play section may be a good place to start.

The short version

The red zone is the area inside the 20-yard line; it is a convention, not an official rule.
The defense's main goal changes from stopping yards to stopping touchdowns, holding the offense to a field goal if necessary.
The shrinking field helps the defense: there is little room behind it, no deep routes and the end line acts like an extra defender.
Coverages shift toward man, two-man, bracket and tighter zones; zero coverage is a high-risk option.
Common offensive plays include fades, slants, rubs, bunches and quarterback runs, and defenders prepare technique for each.
Near the goal line, defenses add linemen, fill every gap and emphasize penetration and leverage.
Penalties such as pass interference are especially costly; the rules differ by level.
