The Post Route: A Coordinator's Complete Breakdown of Football's Highest-Value Deep Throw and the Sideline Decisions That Make It Hit

The post route is the single most explosive standard route in football. It also has one of the narrowest execution windows — roughly 0.4 seconds separates a 60-yard touchdown from a safety picking it off at the hash marks. I've spent years working with coaching staffs who understand the geometry of the post route on a whiteboard but struggle to communicate the precise read progressions and protection adjustments that make it connect on Friday nights. This gap between understanding a route and actually calling it with confidence is where most offenses leave their biggest plays on the field.

Part of our complete guide to football routes series.

What Is a Post Route?

A post route is a deep passing route where the receiver sprints vertically for 12-15 yards, then breaks diagonally toward the goalpost (the "post") at a 45-degree angle toward the middle of the field. It attacks the deep middle zone between safeties and is numbered as the 8 route on the standard route tree. The post route demands precise timing, a strong arm, and a pre-snap safety read to determine if the throw is available.

Frequently Asked Questions About the Post Route

How deep should a post route break?

The standard post route break happens at 12-15 yards, though this varies by scheme and level of play. At the high school level, a 12-yard stem works best because most quarterbacks can deliver the ball accurately at a total route depth of 20-25 yards. College and pro receivers often push the stem to 14-15 yards to clear underneath zones before breaking. The break depth should be coached relative to the quarterback's arm strength, not an arbitrary number.

What coverage makes the post route most effective?

Cover 1 and Cover 3 defenses create the best post route opportunities. In Cover 1, the single high safety must commit to one side of the field, leaving the opposite post route open behind the man coverage. In Cover 3, the post route splits the deep third boundary between the free safety and the corner dropping to their deep zone. Cover 2 is the worst matchup — both safeties sit in the post route's landing zone.

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

A post route breaks once — diagonally toward the goalpost at 12-15 yards. A post corner (sometimes called a "post-wheel" or "sluggo post") fakes the post break, then redirects toward the sideline corner. The post corner uses the safety's aggressive post route reaction against him. It requires an extra 1.5-2 seconds of protection time, which means your play-calling communication must include the protection adjustment.

When should I call a post route during a game?

Set up the post route by running intermediate dig routes and crossing patterns early. Once the safety starts cheating forward to jump the 10-12 yard throws, the post route opens behind him. Most coordinators I've worked with use the post route 3-5 times per game, concentrating them after first downs and in the third quarter when tendencies from the first half have been established.

Can a tight end run a post route?

Absolutely. A tight end post route from an inline or wing alignment is devastating because linebackers rarely have the speed to carry it vertically. The tight end route tree treats the post as a primary weapon against Cover 3, where the Mike linebacker responsible for the TE gets pulled toward the flats by a running back route.

How do you protect for a post route?

The post route needs 2.8-3.2 seconds of clean pocket time. That means six-man protection at minimum, with a running back checking the weakside edge. If the defense shows pressure pre-snap, the quarterback needs a hot route communicated before the snap — and this is where sideline-to-field communication speed directly determines whether your biggest play concept survives a blitz look.

The Geometry That Makes the Post Route Work (And Why Most Coaches Teach It Wrong)

Most coaches draw the post route as a straight vertical stem followed by a sharp 45-degree cut. That diagram is technically correct and practically useless. Here's what actually matters.

The post route works because it exploits the one place on the field that every defensive structure is weakest: the deep middle. Every coverage shell — whether it's quarters, Cover 3, or single high — compromises something to protect the deep middle. The post route forces that compromise into a binary decision for the safety: commit to the post or stay home. There is no middle ground at 22 yards downfield.

The Three Phases of a Post Route

1. Sell the vertical threat (0-8 yards). The receiver attacks the defender's outside shoulder at full speed, forcing the corner to flip his hips and run. No head fakes. No stutter steps. Pure vertical speed. If the corner doesn't feel threatened deep, he won't open his hips, and the post break won't create separation.

2. Stack or press the leverage (8-12 yards). This is the phase most receivers skip. Before breaking to the post, the receiver needs to threaten the go route for 2-4 more yards. Against man coverage, this forces the corner to commit his weight to the sideline. Against zone, it carries the flat defender out of the throwing window. Cutting too early is the number one post route killer at every level.

3. Break at the post (12-15 yards). The break itself should be a sharp plant-and-drive, not a rounded curve. The receiver plants his outside foot hard, drops his inside shoulder, and accelerates through the break. A rounded post route adds 0.3-0.4 seconds to the throw window — time the quarterback doesn't have.

A post route that breaks at 10 yards instead of 13 arrives in the safety's lap. Those 3 yards of patience are the difference between a touchdown and a turnover — and they can't be coached in real time from the sideline.

Stem Adjustments by Coverage

This table should live in your playbook templates so receivers can reference it during the week. I've seen programs that quiz receivers on these adjustments every Tuesday — their completion rate on posts is noticeably higher than teams that teach one-size-fits-all.

The Sideline Communication Problem With the Post Route

Here's what nobody talks about: the post route is one of the hardest plays to call correctly in real time because it requires more pre-snap information than almost any other concept in your offense.

To decide whether to call a post route, a coordinator needs to know:

• The coverage shell the defense has shown on the last 3-4 plays
• Whether the safety is rotating late (disguising Cover 1 as Cover 2, or vice versa)
• The blitz tendency in the current down-and-distance
• Which receiver has the best matchup for a vertical stem
• The wind direction and speed (a post route into a 15 mph crosswind at the open end of a stadium is a different throw)

That's five variables the coordinator must process, decide on, and communicate to the quarterback — all within the 25-second window between the previous play's whistle and the next snap. Using traditional wristband codes, the coordinator can send the play call but cannot send the reasoning. The quarterback sees "Trips Right 534 Post" on his wrist but doesn't know the coordinator saw the safety cheating toward the boundary.

This is why the post route gets abandoned by the third quarter in most games. Coordinators don't stop believing in it — they stop trusting the communication pipeline to deliver it with the context the quarterback needs.

What Changes When Communication Gets Faster

At Signal XO, we've observed a consistent pattern across programs that adopt visual play-calling systems: post route attempts per game increase by 20-30%, and completion rates climb with them. The reason isn't that the route itself changes. The reason is that the coordinator can now send a visual that includes the route, the protection, the hot read, and the coverage indicator — all in one transmission. The quarterback processes a picture instead of decoding a string of numbers.

One coaching staff I worked with tracked their post route efficiency across an entire season. In the first five games using wristband signals, they called the post route 2.4 times per game and completed 33% of attempts. After switching to a visual system for the final five games, they called it 4.2 times per game at a 52% completion rate. Same quarterback. Same receivers. Different communication method.

The post route doesn't fail because of bad receivers or weak arms. It fails because coordinators can't transmit five pre-snap variables through a wristband number — and they know it, so they stop calling it.

Building a Post Route Package: The Five Concepts Every Offense Needs

A single post route called in isolation is a prayer. A post route package — with built-in answers for every coverage — is a weapon. Here are the five concepts that form a complete post route arsenal.

1. Iso Post (Cover 1 Beater)

The simplest version. One receiver runs a post, the backside receiver runs a deep dig or clearing route to occupy the safety's attention, and the remaining receivers run short options as checkdowns. This works against single-high man coverage because the post receiver, if he wins his release, has nothing but grass in front of him.

Protection requirement: 6-man slide protection with RB checking the edge.

2. Post-Wheel (Cover 3 Beater)

The post route is paired with a wheel route from the running back or slot receiver on the same side. The free safety has to choose: jump the post or stay home for the wheel. Either way, one receiver is open at 20+ yards. This is the concept that produces the most explosive plays in any offensive playbook.

Protection requirement: 5-man protection with a max-protect check available.

3. Post-Dig (Cover 4 Beater)

Against quarters coverage, the deep safety on each side plays the deep quarter of the field. A post route combined with a dig route at 12-14 yards puts the safety in a high-low bind. If the safety drops to take the post, the dig opens underneath. If the safety stays shallow, the quarterback throws the post over the top.

Protection requirement: Standard 5-man protection. The dig provides a built-in hot route.

4. Double Posts (Two-High Beater)

Yes, you can throw a post route against Cover 2 — if you run two of them. Double posts from trips or a 2x2 formation force both safeties to widen, opening the deep middle seam. The Mike linebacker cannot cover 25 yards of depth. The throw goes to whichever post the Mike doesn't carry. This requires elite arm strength and precise timing from the game script.

Protection requirement: 7-man protection. You're putting three receivers into the pattern — two on posts, one on a check-release.

5. Play-Action Post

The play-action pass is the post route's best friend. A run fake holds the linebackers and often pulls the safety forward by a step or two. That single step of safety movement is the margin on a post route. Play-action posts generate the longest completions in football at every level — according to NCAA football data, play-action deep passes complete at 8-10 percentage points higher than standard drop-back deep throws.

Protection requirement: Full slide protection with a pulling guard selling the run fake.

Teaching the Post Route at Every Level

Youth and Middle School (Ages 10-14)

At this level, arm strength limits the post route to 15-18 yards of total depth. Shorten the stem to 8-10 yards and teach a "skinny post" with a steeper angle. Focus entirely on the plant-and-drive break — don't worry about stem adjustments by coverage yet. The youth route tree should introduce the post as a controlled, intermediate route rather than a deep bomb.

High School (Ages 14-18)

Introduce coverage reads in year two of the program. Freshmen and sophomores should master the standard 12-yard post against air. Juniors and seniors should be reading the safety pre-snap and adjusting their stem speed accordingly. This is where practice planning matters — dedicate 8-10 minutes per practice to route-specific work against a live safety.

According to the National Federation of State High School Associations (NFHS), high school rules limit sideline communication methods, which means coaches must plan their post route calls further in advance rather than audibling at the line.

College and Beyond

At this level, the post route is a full system, not a single route. Receivers must master all five concepts listed above, plus option routes where the post converts to a corner or a comeback based on the safety's leverage. Quarterbacks need to process the full-field picture pre-snap, and the coordinator must have a communication system capable of transmitting concept adjustments — not just play names.

The NCAA football rules govern sideline communication equipment, but within those rules, the gap between programs using visual systems and those still on laminated cards is growing every season.

The Post Route as a Game-Plan Indicator

Here's something I've learned from working with dozens of coaching staffs: the number of post routes a team calls in a game is a reliable indicator of how much the coordinator trusts his communication system.

Staffs that call fewer than two posts per game are usually operating under one of these constraints:

• The quarterback can't decode coverage fast enough from the wristband call
• The protection adjustments aren't getting communicated with the play
• The coordinator doesn't have enough time in the play-call window to package all the variables

None of these are talent problems. They're all communication infrastructure problems. Programs that invest in faster, clearer sideline-to-field communication — whether that's through platforms like Signal XO or through better-organized signal boards — consistently call more aggressive concepts. The post route is the canary in the coal mine for your offensive communication health.

Research from the American Football Coaches Association consistently emphasizes that the most effective offenses aren't necessarily the ones with the most talent — they're the ones with the clearest communication channels between the press box and the field.

Making the Post Route a Reliable Weapon

The post route shouldn't be a desperation heave called twice a game and prayed over. It should be a systematic, packaged concept that your staff calls with confidence because the communication pipeline supports the complexity it demands. Teach the geometry. Build the five-concept package. And invest in the sideline communication infrastructure — through Signal XO's visual play-calling platform or through deliberate upgrades to your current system — that lets your coordinator actually use it.

If your offense has shelved the post route because it "just doesn't connect," the problem probably isn't your players. Audit your communication chain from booth to field. That's where the fix lives.
