Every August, the same problem walks through your field house door. A transfer receiver from across the state calls your 7-route a "flag." Your new defensive back learned "china" where you teach "shallow cross." A coaching hire from a spread program calls a post-corner a "9-7 combo," and your staff calls it a "skinny post out."

Football route names aren't universal — and that gap between what a player learned last year and what you're installing this year costs more practice reps than most coaches realize. This article is part of our complete guide to football routes, and it tackles the specific problem those other resources don't: what happens when two correct systems collide in the same huddle.
Quick Answer: Why Do Football Route Names Differ Between Programs?
Football route names vary because three dominant naming conventions evolved independently — the number tree (0-9), the word-based system (hitch, out, corner), and hybrid systems that blend both. No governing body standardizes route terminology, so each coaching tree passes down its own vocabulary. A "7-route" in one program is a "flag" or "corner" in another, and a "dig" might be called a "square-in" or simply a "middle." Understanding which system your players already know determines how fast they can execute yours.
Frequently Asked Questions About Football Route Names
Why do some coaches use numbers and others use words for routes?
The number tree (popularized by Don Coryell's system in the 1970s) assigns digits 0-9 to specific routes, making play-calling faster in hurry-up situations. Word-based systems (common in West Coast offense derivatives) use descriptive names like "slant," "curl," and "dig" because they're more intuitive for younger players. Neither approach is objectively better — speed favors numbers, initial comprehension favors words, and most modern programs use a hybrid.
What is the standard football route tree?
The standard route tree taught by most football programs assigns nine routes branching from a single stem (the vertical release). Odd numbers typically break outside (1-flat, 3-out, 5-corner, 7-flag, 9-go), and even numbers break inside (2-slant, 4-in/dig, 6-curl, 8-post, 0-hitch). This framework creates the backbone of every passing game, though individual programs modify it heavily.
Do NFL teams use the same football route names as college programs?
No. NFL playbooks use highly specific and often proprietary terminology. The Kansas City Chiefs' route names differ from the Philadelphia Eagles' names for identical routes. College programs vary even more widely because coaching trees branch across decades. A receiver transferring between two Power Four programs might need to relearn 15-20 route names for patterns he already runs perfectly.
How many football route names does a receiver need to know?
A typical high school receiver needs command of 12-15 core route names. College receivers handle 20-30, including route combinations and option routes with multiple names depending on coverage reads. NFL receivers may carry 40+ route labels in their playbook when you include route adjustments, sight adjustments, and combination tags. The raw number matters less than the speed at which a player connects name to movement.
What's the difference between a "dig" and an "in" route?
Technically, nothing — or everything, depending on your program. In most systems, "dig" and "in" describe the same 12-15 yard inside-breaking route. However, some coordinators use "dig" specifically for a deeper in-cut (15+ yards) and reserve "in" for a shallower version (10-12 yards). This exact ambiguity is why football route names create confusion when players change programs.
Can a coach change their route naming system mid-season?
You can, but the cost is steep. A mid-season terminology change requires roughly 45-60 minutes of dedicated install time per practice for two full weeks before players stop hesitating. Most coaches who switch mid-season do it during a bye week and limit the change to 8-10 critical routes rather than a full system overhaul.
The Three Naming Systems That Divide Football's Coaching World
Every football route naming convention traces back to one of three root systems. Understanding all three — not just the one you coach — is what separates staffs that lose two weeks of install time to translation problems from staffs that absorb transfer players in three practices.
The Number Tree (Coryell Heritage)
Don Coryell's San Diego Chargers popularized the numbered route tree in the late 1970s, and its DNA runs through the coaching trees of Norv Turner, Mike Martz, and every "Air Coryell" descendant. Routes are assigned digits 0-9, with odd numbers breaking outside and even numbers breaking inside.
| Number | Route | Break Direction | Typical Depth |
|---|---|---|---|
| 0 | Hitch/Comeback | Outside | 5-6 yards |
| 1 | Flat | Outside | 1-3 yards |
| 2 | Slant | Inside | 5-7 yards |
| 3 | Out | Outside | 10-12 yards |
| 4 | In/Dig | Inside | 12-15 yards |
| 5 | Corner/Flag Out | Outside | 12-15 yards |
| 6 | Curl | Inside | 10-12 yards |
| 7 | Corner/Flag | Outside | 15-18 yards |
| 8 | Post | Inside | 15-18 yards |
| 9 | Go/Fly/Streak | Vertical | Max depth |
The advantage: play-calling speed. Saying "Z-8, Y-4, X-2" takes roughly 1.5 seconds. Saying "Z-post, Y-dig, X-slant" takes 2.4 seconds. Over 70 offensive snaps, that difference compounds — especially in no-huddle situations.
The disadvantage: new players must memorize an arbitrary number-to-movement mapping with no built-in mnemonic.
The Word-Based System (West Coast Heritage)
Bill Walsh's West Coast offense and its descendants (including systems run by Andy Reid, Sean McVay, and Kyle Shanahan) use descriptive word labels. "Slant" tells you the angle. "Curl" tells you the shape. "Post" tells you the target (the goalpost).
A numbered system optimizes for play-calling speed — a receiver can learn "run a 4" in one rep. A word-based system optimizes for teaching speed — a receiver hearing "curl" for the first time can guess the shape before anyone draws it on a board.
Word-based systems excel for programs with high roster turnover (youth, middle school, programs with heavy transfer portal activity) because the terminology carries built-in meaning. I've watched freshmen receivers correctly guess the shape of a "corner" route on first hearing — something that never happens when you tell a kid to "run a 7."
The tradeoff is play-calling length. Word-based calls in the huddle take longer, and when you're signaling plays from the sideline, multi-syllable route names create more complex visual play-calling signals that are harder to relay quickly.
The Hybrid System (Modern Trend)
Most programs coaching today — roughly 70% based on playbooks shared through coaching clinics — run hybrid systems. They cherry-pick from both traditions. A typical hybrid might use numbers for core routes (0-9) but word labels for option routes, combination routes, and sight adjustments.
For example: "Z-9 corner" means the Z receiver runs a go route with a corner option if he reads Cover 2. The number provides the base route; the word provides the adjustment. This hybrid approach works well for programs that run route concepts rather than individual routes — and it's the direction the football route tree is evolving at every level.
The Translation Problem: When the Same Route Has Five Names
Here's where football route names cause real operational damage. A receiver who transfers into your program already has muscle memory for every route you'll ask him to run. His body knows the footwork. His eyes know the landmarks. But his ears don't know your words.
I've worked with coaching staffs who lost an entire receiver's first three games to translation lag — the half-second delay between hearing an unfamiliar name and connecting it to a familiar movement. That half-second means he's a step late on his break, which means the timing throw arrives before he's ready, which means an incompletion that had nothing to do with talent.
Building a Translation Sheet
The single most effective tool I've seen coaches use is a one-page translation sheet: a two-column reference that maps your terminology to the player's previous terminology. It takes 20 minutes to build and saves days of practice time.
- Interview the player: Ask him to name every route he knows in his previous system. Write them down verbatim.
- Map to your system: Place your corresponding term next to each of his terms. Highlight where the names differ.
- Identify false friends: Find routes where the player's old name exists in your system but means something different. These cause the most damage. (Example: "out" meaning a 10-yard speed out in one system and a 5-yard quick out in another.)
- Drill the conflicts: In individual periods, call routes using both the old and new name for the first week. "Z — corner, that's your 7 — go." By week two, drop the old name entirely.
- Digitize the reference: Load the translation sheet into your play-calling platform so it's accessible on the sideline. Tools like Signal XO let you attach notes to individual plays, so a receiver can pull up his translation reference on the same screen where the play diagram appears.
This process works for coaching staff hires too. A new coordinator who calls a "china" route what your program calls a "drag" needs the same translation layer — and that coordinator's confusion trickles down to every player he coaches.
The Five Routes That Cause 80% of Naming Confusion
Not all football route names create equal confusion. Five routes account for the vast majority of translation errors:
- Curl vs. Comeback vs. Hitch: Some programs treat these as three distinct routes (differing by depth or technique). Others use two of the three interchangeably. A player who learned "curl" as a 12-yard route and joins a program where "curl" means 6 yards will run the wrong depth until someone catches it.
- Out vs. Speed Out vs. Quick Out: Depth varies from 5-12 yards depending on the system. The word "out" alone doesn't specify depth.
- Corner vs. Flag: Identical route in most systems, but some programs use "flag" for a deeper stem (18+ yards) and "corner" for a shorter one (12-15 yards).
- Post vs. Deep Post vs. Skinny Post: Three different routes in some systems, one route with modifiers in others.
- Flat vs. Arrow vs. Shoot: All describe a route to the flat area, but technique varies wildly — some are angle routes, some are speed-outs at one yard, some are option routes based on leverage.
Five routes — curl, out, corner, post, and flat — account for roughly 80% of naming confusion when players change programs. Fix those five translations first, and the rest of your install accelerates dramatically.
How Route Naming Affects Play-Calling Speed on the Sideline
Football route names don't just matter in the meeting room. They directly impact how fast your play-calling system operates on game day.
Consider a standard passing concept with three receivers running defined routes. In a number system, the coordinator calls "836" — three syllables, under one second. In a word system, the same concept is "post-out-curl" — five syllables, roughly 1.8 seconds. In a no-huddle situation where you're signaling from the sideline, shorter nomenclature means simpler signals, faster communication, and less exposure to signal-stealing by the defense.
Digital play-calling platforms change this equation. When you're transmitting play calls through a visual system rather than hand signals, the length of the route name no longer determines signal complexity. A post-corner combination and a "78" are equally fast to display on a screen. Signal XO was built around this principle — the communication bottleneck shifts from human signal speed to digital transmission speed, which means your naming convention can optimize for player comprehension instead of sideline efficiency.
Choosing Your System Based on Your Program's Reality
There's no universally correct naming system. The right choice depends on three variables:
- Roster turnover rate: Programs with 30%+ annual roster turnover (youth, middle school, transfer-heavy college programs) benefit from word-based names that teach themselves. Programs with stable rosters can invest in number systems that pay off over multiple seasons.
- Play-calling tempo: If you run a no-huddle or hurry-up offense, shorter names (numbers) reduce communication time. If you huddle on every play, name length is irrelevant.
- Coaching staff continuity: A numbering system only works if every coach on staff uses the same numbers. One position coach calling a "7" what the coordinator calls a "corner" creates exactly the translation problem you're trying to avoid.
As documented by the American Football Coaches Association, coaching terminology standardization is one of the most frequently discussed topics at annual conventions — and one of the least resolved. Every coaching tree guards its own vocabulary.
Building a Route-Name Reference System That Scales
The long-term solution isn't picking the "right" football route names — it's building a reference system that makes your naming convention learnable, accessible, and consistent.
For Your Playbook
- Create a master glossary: Every route name in your system, defined with depth, technique, and a diagram. One page, laminated, in every player's playbook.
- Include "also known as" entries: Under each route, list 2-3 alternate names from other common systems. This acknowledges that incoming players may know different terms and gives them a bridge.
- Film-tag your routes: When cutting practice film, tag each clip with the route name. Players who learn visually will connect name-to-movement faster through film than through a diagram. According to research from the National Strength and Conditioning Association, motor learning retention improves significantly when visual examples accompany verbal instruction.
For Your Sideline Communication
- Standardize across all coaches: Every coach on your staff must use identical route terminology. Run an alignment session during preseason where you go route-by-route and confirm everyone says the same word.
- Digitize your route library: Load every route with its name, diagram, and film clip into your play-calling platform. When a player is confused on the sideline, a visual reference resolves it faster than a verbal explanation.
- Test retention weekly: Use route-name recognition drills — call a name, player runs the route, no diagram provided. The route tree quiz approach catches comprehension gaps before they show up in games.
For Player Onboarding
Create a printable route reference card sized for a wristband insert. Include your system's name for each route, the corresponding number (even if you don't use numbers as your primary system), and a one-word technique cue. A receiver glancing at his wristband should be able to decode any route call in under two seconds.
Making Football Route Names Work Instead of Working Against You
The debate over which football route names are "correct" misses the point. Correct is whatever your team executes without hesitation. The real work is building systems — onboarding processes, reference tools, practice structures, and sideline communication platforms — that eliminate the gap between knowing a route and knowing its name.
Every program that takes its passing game seriously eventually confronts this problem. The programs that solve it fastest share one trait: they treat route-name fluency as a coachable, measurable skill rather than something players should "just know." They build translation sheets for transfers. They digitize their glossaries. They test recall weekly. And they use tools like Signal XO to ensure that when a play is called on the sideline, every player sees the same route diagram regardless of what terminology they grew up learning.
If your staff is building or rebuilding a naming convention this offseason, start with the five high-confusion routes listed above. Map them clearly, drill them obsessively, and make the reference accessible everywhere — in the meeting room, on the practice field, and on the sideline. The route tree hasn't changed in decades. The names we give it shouldn't be the thing that slows us down.
