Family: Pass concept

What it is: A three-level stretch to one side: deep, intermediate, and flat. It forces one side of the zone to defend multiple depths.

When to use it: Off play-action, boot, or rollouts when the quarterback can read high-to-low.

Good against: Cover 3, Cover 4, and zone teams that do not match vertical spacing well.

Bad against: Man coverage, fast pressure off the boot side, and hard flat defenders collisioning the low route.

Pairs well with: Pairs with outside zone boot and dagger backside.
