How to teach it

  • 1Every front defender owns exactly one gap and fires it on the snap with no reading.
  • 2Get off low and penetrate to disrupt the mesh point and blow up the play in the backfield.
  • 3Corners must play tight man because there is no underneath help behind the pressure.

Common mistakes to fix

  • !Two defenders spilling into the same gap and leaving one open; fix by rehearsing exact gap assignments.
  • !Rushers coming in high and getting reached; fix with low-and-tight get-off reps.
