offense / quick pass
A quick two-route stretch that forces the flat defender to choose between inside and outside leverage.
Animated assignment view
The quarterback chooses the best slant-flat side by comparing corner depth and the apex defender's leverage.
Ball: center
How it works
The outside receiver breaks inside on a slant while the slot expands quickly to the flat. The quarterback reads the defender aligned between them and throws away from his movement.
Provide a fast, defined answer against pressure and isolated underneath defenders.
Win inside leverage without drifting upfield.
Two receivers run to opposite sides of one defender. The quarterback throws to whichever receiver that defender leaves alone.
The concept's spacing depends on a flat route that gains width immediately and a slant that crosses the defender's face without climbing into help.
Decision point
The slant and flat place one underneath defender in conflict: widen with the flat or squeeze the slant.
Deliver behind the flat defender as he widens toward the sideline.
medium riskPut the ball outside immediately when the defender sits in the slant window.
low riskReset underneath if both primary windows close and protection remains sound.
