Cover 3 Sky
Three-deep zone with the strong safety rolling down as the flat defender.
Concept: Strong safety fills the strong flat while free safety, corner, and corner cover the deep thirds.
Base alignment — schematic, not to scale
Every position's job
Defensive Ends
Rush and maintain C/D-gap lane integrity.
Defensive Tackles
Rush the B-gaps, keep the pocket tight.
Inside LBs
Drop to the underneath hook/curl zones, read the quarterback's eyes.
Outside LBs
One rolls to the flat/curl, one supports the deep third rotation.
Corners
Bail to the deep outside thirds.
Safety
Rolls down to the strong flat/run support, other deep player takes the middle third.
How to teach it
- 1Three deep protects against the big play.
- 2Underneath defenders drop to spots and break on the throw.
- 3The rolled-down safety is a run-support force player.
Common mistakes to fix
- !Corners squat instead of bailing and give up the deep ball (fix: open and gain depth first).
- !Underneath defenders chase and vacate zones (fix: drop to landmark, break on the ball).
