Route Combinations in Football: How Smart Play Design Creates Big Plays

In football, passing plays are more than just a quarterback throwing to an open receiver—they're carefully orchestrated attacks built on timing, spacing, and defensive manipulation. At the heart of most passing schemes is the route combination—a strategic pairing (or grouping) of routes meant to put defenders in conflict and create throwing windows.

Let’s dive into some of the most effective route combinations, how they work, and why they’re so important at every level of the game—from youth flag football to the NFL.

🧠 What Is a Route Combination?

A route combination is a coordinated pattern of routes designed to exploit coverage rules and defensive tendencies. Instead of focusing on isolated matchups, these combinations are designed to:

• Stretch defenders vertically or horizontally

• Create mismatches or confusion

• Give quarterbacks clear, progression-based reads

  
  

📚 Popular Route Combinations (with Examples)

Let’s explore some of the most common and effective route combinations used across football.

1. Smash Concept

• Routes: Outside receiver runs a short hitch or curl; inside receiver runs a deep corner.

• Purpose: High-low stretch on a zone cornerback or flat defender. Attacks zone coverage, particularly Cover 2. The hitch route draws the cornerback up, leaving space for the corner route over the top.

• Why it works: Forces the defender to choose between jumping the short route or dropping back, leaving one receiver open.

2. Levels Concept

• Routes: Multiple crossing routes at staggered depths (e.g., shallow cross, medium dig, deep in).

• Purpose: Horizontal stretch across the field, great vs. zone. Stretches the defense vertically by attacking multiple levels of zone coverage, giving the quarterback a clear progression read.

• Why it works: Creates layered options for the quarterback based on the depth of the defense.

3. Flood Concept

• Routes: Deep Route (Post/Go) + Intermediate Route (Out/Dig) + Short Route (Flat) all towards the same sideline.

• Purpose: Overloads one side of the field with routes at different depths, forcing zone defenders to choose and creating open windows for the quarterback.

• Why it works: Most zone coverages only allocate two defenders to a side—three routes means someone is likely open.

4. Mesh Concept

• Routes: Two shallow crossing routes (meshing in the middle), with one or more trailing routes.

• Purpose: Disrupt man coverage and create natural picks. Designed to beat man coverage by creating natural "picks" or traffic in the middle of the field. A go route or deep post is often included to clear out defenders.

• Why it works: Defenders get caught in traffic, making it hard to stay with their assignments.

5. Four Verticals (Verts)

• Routes: Four receivers run vertical “go” routes down the field.

• Purpose: Vertical stretch of safeties and deep zones. Stretches the defense vertically, forcing safeties to make tough choices and creating mismatches, especially against Cover 3 or Cover 4 defenses.

• Why it works: Stresses defenses like Cover 3 or Cover 4 by forcing safeties to cover more ground than they can realistically defend.

6. Stick Concept

• Routes: Slot receiver runs a stick (short out or pivot), outside receiver clears vertically, and back may run a flat.

• Purpose: Quick-hitting option vs. soft zone or blitz. A quick, high-percentage passing concept that forces a defender to choose between covering the stick route or the flat, making it effective against zone coverage.

• Why it works: Gives the QB a fast, reliable outlet—perfect for short-yardage gains.

7. Curl-Flat Concept

• Routes: Outside receiver runs a curl; inside receiver (or back) runs a flat route underneath.

• Purpose: Horizontal high-low stretch on a flat defender. A short passing concept where the curl route forces the cornerback to drop back, while the flat route provides an easy outlet for the quarterback.

• Why it works: Forces the outside zone defender to commit to the deep or short route, leaving the other open.

8. Scissors Concept

• Routes: Two receivers on the same side cross each other—often a post route and a corner route.

• Purpose: Deep zone manipulation, especially vs. Cover 2 or Cover 4. Used to attack two-deep safety coverage. The post and corner routes cross, forcing safeties to make a decision, often leading to an open receiver.

• Why it works: The crossing action confuses safeties and creates space as defenders “switch” or get caught in no-man’s land.

9. Post-Wheel Concept

• Routes: Inside receiver runs a post; outside receiver runs a wheel route up the sideline.

• Purpose: Isolate the wheel route against a linebacker or safety. The post route pulls a defender inside, allowing the wheel route (which starts like a flat before turning upfield) to break open along the sideline. Works well against aggressive defenses.

• Why it works: The post pulls the deep defender inside, while the wheel sneaks behind the underneath coverage for a potential big play.

  
  

🧩 How Coaches Use Route Combinations

Coaches don't just plug in plays at random. They select combinations based on:

• Opponent’s coverage schemes (zone vs. man)

• Field position (red zone vs. open field)

• Down and distance

• Player strengths (speedy slot vs. physical wideout)

By stacking route combinations into their game plan, offensive coordinators build a logical framework that allows quarterbacks to make quick decisions and receivers to find open space.

🧠 Final Thoughts

Route combinations are the backbone of any successful passing offense. They turn chaos into structure, giving quarterbacks tools to dissect defenses and coaches a way to manipulate coverages.

Whether you’re a coach building a youth flag football playbook, a player improving your football IQ, or a fan looking to understand the chess match on the field, knowing these combinations adds a whole new level to watching and playing the game.
