Prevent Cover 4
Deep-drop prevent coverage protecting against the big play late in a half.
Concept: Defenders bail to deep quarters and keep all receivers in front, tackling in bounds to run out the clock.
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.
- 12UIntroduce: Line up right and own your gap — win with alignment, pad level, and pursuit to the ball.
- 14UAttack blocks: Add get-off and block destruction so the front controls the line of scrimmage. Teach the coverage drops behind the front and read run vs. pass. Combine front, pressure, and coverage — and disguise it pre-snap.

How to teach it
- 1Everyone bails to deep quarters and keeps all receivers IN FRONT — no one gets behind you.
- 2Tackle in bounds to keep the clock running late in a half.
- 3Rush lanes stay disciplined; contain the QB so he can't scramble for chunks.
Common mistakes to fix
- !A defender jumps a short route and a receiver gets behind him; fix by teaching top-down, keep-it-in-front discipline.
- !Tackler stops the clock by going out of bounds; fix by teaching in-bounds tackling to bleed the clock.
