Inside Zone

Watch linebacker depth before the snap, since stacked or crashing linebackers signal a run blitz that inside zone can gash if the offensive line gets movement. Key the defensive tackles alignment, because a 1 technique and 3 technique shading away from the play call weakens the double team and opens the backside cutback. User the middle linebacker or a defensive tackle to shoot the gap and blow up the zone combo before it climbs, which is the most reliable way to kill this play. Watch for safety rotation into the box on run blitz calls, since an eighth defender in the box overloads the frontside gaps and forces the cutback read every time. Against a 4-3 under or 3-4 odd front with heavy A-gap presence, inside zone loses efficiency, so switching to Same Side Zone or QB Zone can attack the same look from a different angle.
