📖 Route Trees — Know These 4 Cold

1

F JAILBREAK

📏 46 yards · TURBO formation · Biggest pass play in film
What It Is

The "F" receiver — likely the slot or flex — runs a jailbreak route: a go/vertical designed to beat press coverage by releasing inside or outside and accelerating up the seam. This came from TURBO formation — a spread look that stresses your deep coverage.

How to Play It

No cushion. No single-high safety. This route is designed to beat the CB who gives ground. Jam at the line if possible — force a reroute. If you're in zone, pass it off to the safety at 10 yards and get depth. Your safety MUST be at 12+ yards vs TURBO.

Formation Tell

TURBO spread = shot play threat. The moment you see TURBO, communicate to your safety: "DEEP!" You're in a 2-deep look. Don't let anything get over you.

2

NINER

📏 31-yd TD · TURBO STACK formation · Their go-to TD pass
What It Is

NINER is a fade/corner route (9-route) — a receiver attacks the deep corner of the end zone. From TURBO STACK, they have multiple receivers threatening different levels. This is their red zone and chain-mover shot play.

How to Play It

From STACK formation — it's ALWAYS a pass. You know it. Play leverage. On NINER, your job is to not let the WR get to the corner of the end zone. Play inside leverage from STACK and force the route outside — into your safety's range.

QB Tell

Watch the QB's eyes pre-snap. If he's staring at your side from STACK, he's coming to you on NINER. Pre-rotate slightly toward the deep corner. Do NOT bite on a jab step — the WR will sell run-block before releasing on the 9-route.

3

Y SPECIAL A JERK

📏 32 yards · TURBO formation · Crossing / jerk route
What It Is

The "JERK" tag means a stop-and-go or double-move route — the receiver sells an out or curl at 8-10 yards, then breaks back vertical or across the field. It exploits DBs who bite on the first move. This is their route to get a CB out of position.

How to Play It

DO NOT bite on the first break. Read the receiver's hips, not his head. When you see the shoulder dip at 8 yards, stay patient — he's about to jerk. The second break (vertical or crossing) is the actual route. Maintain inside leverage throughout.

Coverage Tip

In zone coverage, this route attacks the void between your flat zone and the deep third. At 10 yards, communicate with your LB: "Crossing! Crossing!" — so the LB can carry him and you can fall back for the vertical threat.

4

OSCAR

📏 22-yd TD · CLOSE STACK formation · Red zone special
What It Is

OSCAR from CLOSE STACK is a compressed formation route — likely an inside receiver releasing on a corner or out route in tight space. The "CLOSE STACK" bunches receivers, creating natural pick routes and forcing man coverage conflicts.

How to Play It

Red zone — no single coverage on stacked receivers. Communicate picks — if you're on the inside man of the stack, be aware of the pick route. Play zone in the red zone vs CLOSE STACK. Let your safety help over the top on the inside release.

Red Zone Alert

CLOSE STACK near the goal line = TD threat. Call it out: "STACK RED ZONE!" DC will likely call zone or 2-man — be ready to adjust from man to zone on the fly if they show CLOSE STACK inside the 20.

🗺️ Formation → Coverage Assignment

FormationRun/Pass TendencyCB Coverage
STACK 100% PASS 2-DEEP ZONE — no single high. Drop immediately at snap.
TURBO Pass-heavy / Shot plays 2-DEEP — F JAILBREAK and NINER both came from here. Stay deep.
TRIO 62.5% RUN PRESS — they're likely running. Jam the WR, help on run support.
UNDER TEA 75% RUN PRESS — heavy run formation. Get physical at the line.
CLOSE STACK Pass (red zone) ZONE — OSCAR TD came from here. Communicate picks, play zone.
BASE / SPLIT Mixed ZONE UNTIL KEYS READ — use motion to decide. See below.

🚦 Pre-Snap Motion Keys for CBs

🏃

YAMAHA Motion → RUN (100%)

When you see YAMAHA motion, creep up. It's a run. Help in run support. Don't be caught deep on a run play — their WRs will block downfield and you need to make the tackle.

📡

BUS Motion → PASS (100%)

BUS motion = lock into coverage. Don't bite on the run fake. Slide into your zone depth immediately. The pass is coming. Find your receiver and don't let him release free.

🏃

BOUNCE Motion → RUN (100%)

Small sample — but BOUNCE is also a run tell. Follow the YAMAHA rule: get physical at the line, prepare to make run support tackles.

TRAIN Motion → MIXED — Stay Disciplined

The 67-yard TD run came with TRAIN motion from Split. Don't over-commit to run OR pass on TRAIN. Play your assignment first. Don't gamble.

✅ CB Pre-Snap Checklist

NINER: Stack Release — Seam Route

TURBO STACK · CB alignment vs stacked WRs · Inside release key
CB Key

STACK alignment — receivers are bunched tight. You cannot play press easily because they'll rub you. The outside receiver releases vertical (your guy), the inside one releases on a seam. Play off coverage, jam at 3 yards. If the FS is shallow, bracket the seam receiver.

F JAILBREAK: Go Route — 46 Yards

TURBO formation · CB gave too much cushion · Do NOT bail deep
CB Key — DO NOT REPEAT

F receiver (flex/TE) aligned outside. CB bailed 10 yards off. F ran a go route straight up the seam — 46 yards. TURBO is their vertical shot package. Play press or tight off-coverage on the F receiver. Reroute him inside at the line. Do not give a free release on vertical routes.

Y SPECIAL A JERK: Crossing Route — 32yds

TURBO · Y receiver crosses after a jerk move — double-move awareness
CB Key

Y receiver runs a stem-and-jerk before crossing. CBs who bite on the first break give up the cross for big gains. Read the hips: first move is a fake, second move is the real route. Stay square, click-and-close on the second break. They hit this for 32 yards when the CB bit early.

FLUTIE w/ BUS Motion: Play-Action Pass

BASE formation · BUS motion right · Pass play — CB must not bite on motion
CB Key

BUS motion = 100% pass. As the CB, when you see BUS motion, lock in on your receiver — don't follow the motion man. FLUTIE is a short-to-intermediate route concept. Stay in your zone/man assignment. The motion is to pull your eyes off your man.

OSCAR: Red Zone Corner Route

2nd & 4 · CLOSE STACK · Red zone · 22yd TD
CB Key — Red Zone Alert

CLOSE STACK red zone. OSCAR concept — receiver runs a corner route off a stack alignment. In the compressed red zone, there's no room to bail. Play tight off-coverage at 3 yards. If you see CLOSE STACK inside the 20, go to zone — the rub routes will eat man coverage alive.
