Cover 4 Quarters
Four-deep zone dividing the deep field into quarters for passing downs.
Concept: Corners and safeties each cover a deep quarter and read keys to trigger downhill on run.
Grows with your players
Same play, more layers as they age up — teach it once and build on it every season for a consistent program.
- 6UIntroduce: Line up right and own your gap — win with alignment, pad level, and pursuit to the ball.
- 8UAttack blocks: Add get-off and block destruction so the front controls the line of scrimmage.
- 10UAdd coverage: Teach the coverage drops behind the front and read run vs. pass.
- 12UFull call: Combine front, pressure, and coverage — and disguise it pre-snap.

How to teach it
- 1Each deep defender owns a quarter and reads his key (number two) to trigger downhill on run.
- 2Safeties are run-pass conflict players, so they read first before committing.
- 3Corners stay over the top of the outside receiver's vertical.
Common mistakes to fix
- !Safeties triggering on play-action and giving up the seam; fix by reading number two's release first.
- !Corners squatting on the flat and losing the deep quarter; fix by staying on top of number one.
