Flag Route in Football

What is a flag route?

The flag and the corner are two names for the same route. On FlagSketch's numbered route tree, it is route 7. The pylon is a direction cue, not a requirement to reach the end zone: from midfield, the receiver still breaks toward the sideline at the called depth.

A flag sells a vertical stem, then leaves for the sideline. The quarterback gets a target running away from the defender, toward the boundary. It is a deeper throw than a hitch or a slant. Match the timing to your league's passing clock and rush rules. In NFL FLAG, the seven-second passing clock and the seven-yard rush line are separate rules: an eligible rusher can come at the snap. Seven seconds is not seven seconds of protection. Be ready to release as the receiver breaks, or take the short route if pressure arrives first.

How to run a flag

Stem depth by age and format

Count yards, or put a cone down. Flag fields do not share one set of tackle-football hashes, so a landmark has to be a number of yards your players can see. The angle stays about 45 degrees at every age. What changes is how far they stem before they break.

• First-year players and roughly ages 7–8: break at 6–8 yards. The cone is the lesson. A stem that is too deep turns into a player who keeps running, or a throw the quarterback cannot reach. If the arm cannot get the ball there, teach the shape at practice and call a shorter route in the game.
• Most youth teams, including 5v5: break at 8–10 yards, on the same spot every rep. The catch comes a few yards after the break, near the sideline. That 8–10 yard break is the landmark on the numbered tree.
• Older players with the arm strength and field space: push the stem to 12–15 yards, then the same angle, so the catch can be 15 yards or more downfield. Player count alone does not set the depth. A bigger field does not flatten the break into an out. A square cut at about 5 yards is an out. A stem with no break is a go.

Use the same depth on the left and the right. A flag that breaks at 8 yards on one side and 15 on the other is two routes. Pick one cone for the team you have.

The break

Stem on a straight line, at the defender's outside shoulder. Drifting toward the sideline on the way up tells them the break is coming, and it moves the landmark the quarterback is throwing to.

At the cone, sell the post for one beat. The eyes and the inside shoulder peek toward the goal post. That is the whole fake. A long stutter lets the rusher arrive and gives the defender time to recover.

Then plant the inside foot. That is the foot nearest the middle of the field. A receiver breaking toward the right sideline plants the left foot. Sink the hips and drive toward the pylon at about 45 degrees. A square cut is an out. A soft banana is a fade. The route leaves the cone on a straight line.

The cue that holds up at practice: "Stem, show the post, break to the pylon."

Eyes stay up the field on the stem. After the break, locate the ball over the shoulder and adjust the hands to its height and angle. The catch is near the sideline, with the receiver still in bounds. Stay on the 45-degree line through the catch, then turn upfield.

Walk the route once so everyone sees the cone. After that, run it at full speed. A break that only looks sharp in a walk-through will round off once the game speeds up.

The route running drills are where the plant gets rehearsed. The flag is a break-point route. Full-speed reps at a cone teach it faster than another whiteboard drawing.

Quarterback timing and where to throw

The ball leaves as the inside foot hits. Waiting until the receiver is already at the pylon spends the window the route just created, and it gives the safety time to get over.

• Catch the snap and peek the flag side. Staring the receiver down tells the defender to stay outside.
• Match the shotgun footwork to the route depth in practice. Be balanced and ready as the receiver plants; do not add a long drop that delays the throw. Check your league's passing clock and rush rule separately. If pressure arrives before the break, take an open short route.
• Aim for the outside shoulder, on a line that leads the receiver toward the sideline and away from the defender. Against man, lead the receiver away from the trail defender. Against zone, use enough arc to clear the underneath defender while arriving before the safety; a flat bullet can be intercepted underneath, while a hanging floater gives the safety time to close.
• A ball thrown back to the inside shoulder is a throw into the safety, or into the defender who is still inside. If that defender is already outside the receiver before the snap, do not throw the flag. Throw the flat, the hitch, or the post.

Footwork for the rest of the dropback is in the flag football QB development guide.

How the flag beats man and zone

Man coverage

The flag wins when the defender is even or to the inside. The head-and-shoulder sell opens them toward the post, and the break toward the sideline creates separation outside. The ball is already going to the outside shoulder.

Outside leverage is the other look. The defender is between the receiver and the sideline before the snap, so the break runs into them. Throw the post, or the flat underneath.

A no-contact flag game has no jam. The stem is free. The defender has to turn and run with a vertical, then flip when the receiver leaves for the sideline. That is why the sell matters. A flag with no post fake never opens the defender inside, so a corner who is already outside stays on the hip.

Zone, and a corner who squats

The flag can open when the corner over the receiver is sitting short and the safety cannot close the window. It is a poor throw when that corner is already dropping deep and outside.

In Cover 2, two safeties split the deep field and the corner plays the flat and the curl. That corner squats. The flag breaks behind them, in front of the safety who owns the deep half. The hole on the sideline is the throw.

In Cover 3, the corner owns a deep third and should drop. A flag into a corner who is bailing runs into that defender. Throw the flat or the hitch underneath, in the space they left. If that Cover 3 corner squats instead — they jump the flat, or they sit — look for the flag behind them, then confirm that no rotating safety has taken that space. Read the corner's hips and the deep help, not just the name on the call sheet. A bailing corner usually leaves room for the route underneath.

A flat underneath the flag makes that one read. The flat gets width right away, about 3–5 yards toward the sideline. The flag breaks high and outside. If the corner drops with the flag, throw the flat. If the corner sits on the flat and the deep window is clear, throw the flag. Use a hitch at 5–6 yards instead of the flat and the pair is Smash.

5v5

Five defenders. One rusher leaves four in coverage. The offense has four routes once the center releases: three skill players plus the center.

On a small field the flag is a shot, not the first play you install. Pair it. An outside flag with a flat from the same side puts the corner in conflict. The center's short release is the checkdown when the rusher arrives before the break. Two flags ask both deep defenders to be wrong at once. One flag, and a short route under it, is enough.

6v6

Six defenders. One rusher leaves five in coverage for five routes: four skill players plus the center.

Against Cover 2, the corner squats, and a safety owns the deep half. The flag is the high throw. A hitch or a flat is the low throw. A flag with nothing under it lets that corner turn and run with it.

The safety can still get over if nothing else holds them. A go or a post away from the flag, or a seam, keeps that safety from sitting on the sideline break. If the safety is already wide to the flag side before the snap, throw the other way.

7v7

Seven defenders. One rusher leaves six in coverage for six routes: five skill players plus the center.

If the field and quarterback allow a 12–15 yard stem, use it here. Smash is the edge read: the flag breaks high and outside, and the hitch sits at 5–6 yards. If the corner drops, throw the hitch. If the corner sits, check the safety before throwing the flag. A two-high defense can help on both sides; choose an open window rather than assuming one edge is uncovered. Install one side before you run the read to both edges.

Against man with one rusher, six defenders can match all six eligible receivers, including the center. The center is uncovered only if the defense leaves them unassigned. The flag is the throw to the receiver whose defender has inside leverage.

Flag route vs post route vs corner route

Two of these names are the same route. The third is the break in the other direction.

Corner route. The chart name for this path. Route 7. Vertical stem, then about 45 degrees toward the sideline.

Flag route. The same path. The word points at the pylon in the corner of the end zone, which is why flag-football coaches already say "flag." It does not mean a play about pulling flags. Pick either word for your sideline. Use one name and one cone so the practice sheet and the call match.

Post route. The opposite break. Route 8. The receiver stems the same way, then breaks about 45 degrees inside, toward the goal post. The 5 essential routes page teaches that inside break. The post attacks the middle. The flag attacks the sideline.

Post versus flag is one choice after the same stem. If the safety stays in the middle, throw the flag to the sideline. If the safety widens to take the flag, throw the post. They leave the cone in opposite directions.

Routes that make the flag a play

Flag and a flat

A high-low that a young quarterback can learn as one read. The flat gets width immediately. The flag breaks over the top at about 45 degrees. One corner. If they sit on the flat and the safety cannot close, throw the flag. If they drop with the flag, throw the flat.

Swap the flat for a hitch and the same read is Smash. The Smash templates are drawn with that short stop under the corner.

The same shape is in the 6v6 Smash and 7v7 Smash templates. Y-Sail is the Air Raid version with a corner and a shorter route that gets width: 5v5 Y-Sail, 6v6 Y-Sail, and 7v7 Y-Sail.

Draw the pair in the play creator. It works without signup.

Flag and a go

Two deep routes, and one defender who cannot be on both. The go holds the safety high. The flag breaks outside, away from that safety, toward the sideline. If the safety stays on the go, throw the flag. If the safety widens to the flag, throw the go.

On a small 5v5 field, two deep routes and no flat leaves the quarterback with nothing when the rusher wins. Keep a flat or a hitch on the flag side so the deep read has a short answer.

Common mistakes

The break is rounded

The receiver banana-cuts and leaks toward the sideline with no plant. The quarterback throws to the 45-degree landmark and the ball sails past the outside shoulder. Plant the inside foot and snap the angle. The route leaves the cone on a straight line.

There is no post sell

The receiver breaks outside without showing the post. The defender never opens inside, and the flag becomes a slow out into outside leverage. One beat: eyes and inside shoulder toward the post, then the break to the pylon.

The cut is an out, or there is no cut

A square break at about 5 yards is an out. A receiver who keeps running with no angle is on a go. The flag is the stem, then about 45 degrees to the pylon. Cone the break until it is the same route every rep.

The ball is thrown to the inside shoulder

Throw to the outside shoulder, toward the sideline, away from the defender. A ball thrown back inside is a throw the safety can catch. If the corner is already outside before the snap, check to the flat.

The stem does not match the arm

An 8-year-old asked to break at 15 yards will round the route, or watch the ball fall short. Cone the depth your quarterback can actually throw, and use that cone for every receiver.

The flag is the only route on that side

A corner who has nothing underneath can turn and run with the flag. Put a flat or a hitch under it so that defender has to choose a depth.

Frequently Asked Questions

What is a flag route in football?

A flag route in football is a receiver route, also called a corner route. The receiver stems straight upfield, then breaks about 45 degrees toward the sideline and the pylon. It is not about the flags players wear. On FlagSketch's numbered tree it is route 7.

Is a flag route the same as a corner route?

Yes. In flag football, the flag route and the corner route are the same break: a vertical stem, then about 45 degrees toward the sideline. Flag is the name many coaches use, because the receiver runs at the pylon. Corner is route 7 on the numbered tree. Teach one name and one cone.

What is the difference between a flag route and a post route?

A flag route and a post route use the same vertical stem, then break opposite directions. The flag, also called the corner, is route 7 and breaks outside toward the sideline at about 45 degrees. The post is route 8 and breaks inside toward the goal post at about 45 degrees. If the safety sits in the middle, throw the flag. If the safety widens toward the flag, throw the post.

How deep is a flag route?

Most youth teams break a flag route at 8–10 yards, then continue toward the sideline. First-year players and roughly ages 7–8 can break at 6–8 yards. Older players with enough arm strength and field space can push the stem to 12–15 yards, with the catch farther downfield toward the sideline. Choose depth by ability and space, not player count alone. A square cut at about 5 yards is an out, not a flag.
