Single-high shell out of the 4-3 Over — three deep thirds behind four underneath zones, front four coming.

The call

• and @CB2 bail to the outside thirds; owns the deep middle
• drops to the left flat; takes the right flat
• and wall the hooks and rob anything crossing shallow
• , , @DT2, @DE2: get after the QB — contain first on the edges, push the pocket inside

When to call it

• Your base call against run-heavy teams — eight defenders near the box before the snap
• Early downs when you want safe, sound football

Where it gets stressed — and the answer

• Vs four verticals, three deep get stretched: splits the seams and stays disciplined in the middle third; and carry the inside verticals until they clear
• Quick outs in front of the bailing corners: rally, tackle, keep everything in front

Coaching points

• Corners: nobody behind you — pedal to your third before you drive on anything
• : you're the eraser — align deep and break on the ball
