Family: Coverage

What it is: Four deep defenders each own a quarter of the field, with safeties often reading run/pass and matching vertical routes.

When to use it: Against spread formations and teams that threaten four verticals.

Good against: Deep routes, balanced 2x2 formations, and offenses trying to isolate one safety.

Bad against: Quick underneath routes, well-timed RPOs, and run schemes that stress safety fits.

Pairs well with: Pairs with match quarters and Palms.
