Cover 4

The Cover 4 tag collects every quarters-based zone shell in the game, spanning 85 plays across 9 formations and 53 sets from Nickel and Dollar to 4-3, 3-4, and Quarter personnel. These calls split the deep field into four vertical zones with the corners and safeties reading route stems, making them the go-to answer against verticals, corner routes, and post concepts while keeping run support honest with match principles on the number two receiver.
