Spot
Triangle read targeting the flat defender
Three receivers form a triangle: the outside receiver runs a corner at 12-15 yards, a receiver sits at the "spot" (4-6 yards on the vertical stem), and a third releases to the flat. The QB reads the flat defender through a high-to-low progression: corner, spot, flat. Cover 2 brackets the concept effectively (safety overtops corner, CB covers flat, LB covers spot). Especially potent in the red zone from bunch formations where compressed space disrupts man coverage.
Route Assignments
Corner route at 12-15 yards — the high read in the triangle.
Spot/sit route at 5 yards — sits in the void between the flat defender and LB.
Flat route — the low read in the triangle progression.
Go route to clear out the backside and hold the safety.
Check-down to the backside flat as safety valve.
Read Progression
High-to-low triangle read on the flat defender: corner first (if flat defender bites down), then spot (sitting in the void), then flat (if both are covered).
Why It Works
The triangle creates three options at three different levels against one defender. The flat defender cannot cover the corner, the spot, and the flat simultaneously. The QB reads one defender and works through the progression.
