The Screen Pass: Why It Works
The screen pass invites the defense to rush the quarterback, then hands the ball to a runner with blockers in front. Here is how it is built, who it fools and why it fails.
It is third-and-long, the crowd is loud, and the defense is pinning its ears back. Every defensive lineman knows the offense must throw, so every defensive lineman is thinking about one thing: getting to the quarterback. The quarterback drops back, looks downfield, and then lofts the ball softly over the heads of the onrushing linemen to a running back standing alone near the sideline. A wall of blockers is already in front of him. The back catches the ball, tucks it, and sprints upfield while the defenders who were chasing the quarterback are now eight yards behind the play.
That is a screen pass, and it is one of the few plays in football that wins by getting the defense to do exactly what it wants to do. This article explains how a screen is built, the main versions you will hear called, the signs defenders look for, and the reasons a screen that looks beautiful on a whiteboard can turn into a loss of yards in real life.
The basic idea: let them in, then go around
Most pass plays fight the pass rush by blocking it. A screen takes the opposite approach for a moment. The offensive linemen set up as if they were pass blocking, let the defensive linemen come through or around them, and then release to the side to run in front of the receiver. The quarterback drops back, sells the idea that he is looking for a deep target, and throws the ball a short distance, usually just behind the line of scrimmage, to a receiver with blockers waiting.
Three things have to happen for a screen to work:
- The pass rush has to commit. If the defensive line stays at home, the linemen have nobody to get around, and the whole play is just a short throw into traffic.
- The blockers have to arrive. Linemen who release too early tip off the defense. Linemen who release too late are not in position when the catch is made.
- The ball has to be thrown at the right time and in the right place. Too early and the rushers are still near the quarterback. Too late and the defense has recovered.
The result is a play that turns the defense's strength, a fast and aggressive pass rush, into a weakness. A defender running hard toward the quarterback cannot easily change direction and run back toward the sideline, and a team that blitzes can be punished because the defenders who would normally tackle a running back in space are the ones who just left.
Who catches the ball, and the main versions
"Screen" is a family of plays rather than a single call. The names vary by team, and some coaches use the same name for different things, but the common versions are consistent enough to describe.
Running back screen
The classic. The running back begins by pass blocking for a moment, or by showing a run action, then slips out of the backfield and drifts toward one side. Offensive linemen from that side peel away from their rush assignments, form a short line in front of him, and escort him up the sideline. This version has the most obvious timing: the back must wait long enough for the rush to get past him and the blockers to set up, but not so long that a linebacker reads it and lingers.
Many teams use a version of this called a slip screen, where the back appears to block a rusher for a beat and then slips past him into the flat. The fake block is the deception.
Wide receiver screens
A wide receiver screen puts the ball in a receiver's hands at or behind the line of scrimmage, usually near the sideline, with other receivers and sometimes linemen blocking in front. Two common names:
- Bubble screen. An inside receiver, often the one in the slot, takes a step or two toward the quarterback as if running a quick route, then turns outside and catches a quick, flat throw. The receivers near him block the cornerback and the nearest defenders. The route looks like a bubble drawn in the air, which gives the play its name.
- Tunnel screen. The receiver steps back toward the quarterback, catches a short throw, and runs into a "tunnel" created by blockers, including linemen, who release to that side and take on defenders in front of him.
Teams that spread the field often treat the bubble screen as a quick-game throw that is essentially a handoff with a pass. It is called more because the defense must spread out to cover the whole field, which leaves the player with the ball in space.
Tight end and middle screens
A tight end can be the screen target too. A middle screen has a back or tight end catching the ball in the middle of the field, with the guards and center releasing to lead him. It is rarer because the ball has to be thrown over the middle of the rush.
Jailbreak screen
In a jailbreak screen, a group of blockers forms a wall and the receiver runs behind it. Usually the receiver is near the line, with linemen and receivers working as a cluster, and the quarterback's throw is quick and flat.
Why defenders cannot simply ignore it
You might think a defense can avoid being burned by a screen simply by not rushing the quarterback so aggressively. But a defense that does not rush loses its most important weapon on passing downs. A quarterback with time to throw is dangerous, and a defense that sits back and plays only the screen gives up easy completions on other routes.
This is the basic tension of screens: the defense has to be aggressive enough to disrupt a normal pass and disciplined enough to stop and react if the play is a screen. Defenses spend practice time on screen awareness for exactly this reason. A few typical solutions:
- The rusher who feels the block is too easy. If an offensive tackle lets a pass rusher run past him without much contact, a smart rusher recognizes that this is unusual. Real pass protection usually fights; a block that gives way invites suspicion.
- The late-drop defender. A linebacker or safety who sees the running back leaking out instead of staying home to block takes a step backward, away from the quarterback, to be in position for a possible throw.
- The turn-and-chase habit. Many defenses teach linemen who recognize a screen to stop rushing, turn, and chase the ball carrier from behind.
Because defenders cannot know before the snap, offenses try to call a screen at times that make a pass rush likely. Two situations are commonly cited:
- Obvious passing downs, such as third-and-long, when a defense is likely to pin its ears back.
- After the defense has been successful rushing, because a team that has recently hit the quarterback or recorded sacks is likely to come with a similar rush.
Blitzes and screens
Screens have a reputation as the answer to a blitz, and the logic is straightforward. A blitz sends extra rushers, which means fewer players are left in coverage. If the quarterback reads the blitz and throws a screen, the blockers are facing fewer defenders than usual downfield, and the ball carrier is in space where only a couple of defenders remain.
That said, the offense has to read the blitz in time, and most screens are called before the snap rather than switched to at the line. A quarterback who sees a blitz coming and has a screen available as an automatic can use it, but he needs the protection and the receiver in the right spot. If the blitzer reaches the quarterback before he releases the ball, the play is dead, and the quarterback may be sacked for a loss. Our overview of blitz types and pressure packages describes the ways defenses send extra rushers, which also explains why some blitzes are easier to screen than others. A defense that sends a pressure from the side where the screen is set, for example, can hurt the play.
What the offensive line actually does
The blockers are the center of the play, and the work is subtler than it looks. On a running back screen, the linemen on the side of the throw go through a sequence:
- Pass set. They take their normal pass-blocking stance for a count or two, looking like any other protection.
- Allow the rush. They let the defenders get upfield, often steering them past the quarterback rather than fully stopping them.
- Release. The designated linemen turn and run toward the sideline, usually keeping their eyes on the nearest defender they intend to block.
- Block in space. They find the defenders who are chasing the ball and take them out of the play, often by blocking the nearest defender, then the next one.
Our guide to pass protection schemes explains the normal philosophy; a screen deliberately abandons it for a count or two. The linemen on the side opposite the throw typically continue to block the rush to protect the quarterback. If they stopped, he would be hit as he threw.
The rules that shape it
Linemen are normally ineligible receivers, meaning they cannot catch a forward pass and, in most cases, cannot be far beyond the line of scrimmage when a forward pass crosses it. A screen is designed to work within those rules because the ball is thrown behind the line, and rules about ineligible players going downfield generally apply to passes that cross the line. The specific limits, and the way they are written for run-pass options, differ by level and by year, so read our explanation of ineligible receivers downfield and screen pass rules for the full picture, and check the current rulebook for your level.
Penalties that can end a screen include:
- Holding by a blocker who grabs a defender instead of using legal hand placement.
- Illegal use of hands and similar contact fouls.
- Ineligible receiver downfield, if the pass actually travels past the line.
- Illegal blocking by receivers, in situations where the rules limit how early or how far downfield a receiver may block.
The last varies the most. Rules about receivers blocking before the catch differ between levels and are revised from time to time, so a coach who builds a bubble screen with receivers blocking at the line has to know what is legal in his league this year.
Timing: the hardest part to teach
A screen looks simple and is often executed badly. The problem is timing, and it shows up in three ways.
The quarterback's patience. He has to hold the ball long enough for the rush to commit, yet every instinct says to throw quickly. If a rusher is on him before he releases, the play is lost. Many screens are thrown with a defender in the quarterback's face, and the throw is made over or around him.
The receiver's patience. The back or receiver who is the target must stay at the right spot until the blockers arrive. If he runs into the open too early, he is easy for a defender to see.
The blockers' spacing. If the blockers are too close to the ball carrier, a single defender can tackle him and a blocker simultaneously. If they are too far in front, the ball carrier cannot use them. The best screens have blockers who are about a few strides ahead of the receiver and who each take a different defender.
In practice, teams rehearse the screen against a scout team that plays the part of the aggressive defense, repeating it until the three timings line up. The exact count varies from play to play and from team to team.
Common mistakes and why screens fail
A screen can go wrong in several ways:
- The defense recognizes it. A defensive lineman who sees the blockers releasing may stop his rush and cover the throw, which turns a screen into a loss.
- The throw is off. A pass that is too high, too low or too far from the receiver is an incomplete pass. If it is behind the line of scrimmage and is not caught, it is still a forward pass that falls incomplete, so the cost is a down rather than a turnover.
- The blockers get lost. If one lineman's assignment is confused, an unblocked defender makes the tackle.
- The quarterback is hit. If a rusher reaches him before the throw, the play becomes a sack or, worse, a fumble.
- The call is stale. A defense that has seen a screen on a certain down and distance several times may take the screen away by keeping linemen at home.
What to watch for on your next broadcast
Screens offer clues you can recognize live, even if you have never played.
- The line looks wrong. Pass protection normally holds a tight pocket. If the tackle lets a defender slide by and then turns to run to the sideline, a screen is likely.
- The back goes out slowly. A running back who walks into the flat rather than sprinting is almost certainly part of a screen.
- The quarterback's eyes. Quarterbacks on screens often look downfield first, then back to the target. The look-away is part of the deception.
- Receivers blocking at the line. On wide receiver screens, you will see receivers stand tall at the line to occupy cornerbacks rather than release downfield.
When you see a screen succeed, notice which defender is missing at the point of attack. The play usually works because someone who should have been there, a rusher or a linebacker, was pulled to another part of the field. After a game, check the final numbers on our scores page and the individual lines on player pages; a back with a few catches and a surprisingly long reception often had a screen behind it.
The short version
- A screen invites the pass rush to come through, then throws the ball short to a receiver behind a group of blockers.
- The main types are the running back screen, the bubble screen, the tunnel screen, the middle screen and the jailbreak screen.
- It works best when the defense expects a pass and rushes aggressively, such as on obvious passing downs.
- The offensive line pass-blocks for a moment, lets the rush through, and then releases to the side to run in front of the ball carrier.
- Timing is the hardest part: the quarterback, the receiver and the blockers must each wait just the right amount.
- Screens fail when defenders recognize the blocks, when the throw is off or when the quarterback is hit.
- Rules on ineligible players, blocking and contact before the catch vary by level, so check your league's rulebook.
