Cover 4 Quarters

Four-deep zone splitting the field into quarters against spread pass sets.

Same play, more layers as they age up — teach it once and build on it every season for a consistent program.

  1. 6UIntroduce: Line up right and own your gap — win with alignment, pad level, and pursuit to the ball.
  2. 8UAttack blocks: Add get-off and block destruction so the front controls the line of scrimmage.
  3. 10UAdd coverage: Teach the coverage drops behind the front and read run vs. pass.
  4. 12UFull call: Combine front, pressure, and coverage — and disguise it pre-snap.

How to teach it

  • 1Each corner and safety takes a deep quarter and reads the number-two receiver for run-pass keys.
  • 2Safeties trigger downhill only after confirming run through number two's release.
  • 3Corners stay on top of number one's vertical.

Common mistakes to fix

  • !Safeties triggering on play-action and giving up the seam; fix by reading number two first.
  • !Corners squatting and losing the deep quarter; fix by staying over the top of number one.
