Klint Kubiak & Wide Zone / Play Action Principles Modern offenses stress second-level defenders (linebackers and safeties) with run-action flow. When the running back attacks the perimeter on outside zone, linebackers bite forward, creating massive voids behind them for intermediate crossing dig and sail routes.

The 3-Level High-Low Read In concepts like Flood and Dagger, routes are stacked vertically at 4–6 yards (Flat/Under), 12–15 yards (Sail/Intermediate), and 25+ yards (Clearout Post). A single cornerback or safety cannot defend two vertical levels simultaneously.
