How the split-field coverage works, why defenses use it and how to attack each half." url: https://www.crucibletech.com/playbook/coverages/cover-6/ --- coverage # Cover 6 Defense Cover 6 is a split-field coverage: quarters (Cover 4) to one side and a two-deep half-field side to the other, with a deep half safety over a cloud corner. Defenses use it to match a coverage to each side of a formation, typically quarters toward the passing strength and the half-field side to the weak side. ![Cover 6 coverage diagram](https://www.crucibletech.com/playbook/img/football_11v11/coverages/cover-6.webp) ## How Cover 6 Works On the quarters side, the corner and safety each play a deep quarter and the safety reads the No. 2 receiver. On the half-field side, the safety plays the deep half and the cloud corner squats in the flat. In Crucible's diagram the free safety takes the left half with the corner sitting short, and the strong safety and corner on the right play quarters. The underneath defenders fill the hook and curl zones between the two halves. ## Where Cover 6 Is Weak - The sideline hole on the half-field side, between the cloud corner and the half safety, for corner and sail routes. - The flats on the quarters side, where the corner plays deep. - Motion or shifts after the defense has declared which half is which, so it ends up on the wrong side. ## How to Recognize It - Two high safeties, but the two sides of the field look different. - On one side the corner is rolled up close to the line with the safety deep and wide. That is the half-field side. - On the other side the corner is off and the safety sits at linebacker-plus depth. That is the quarters half. - Defenses usually set it by the formation, so the formation tells you where to look. - At the snap the cloud corner jams and sits while that safety bails to the half, and the quarters safety sits and reads No. 2. ## How a QB Reads It Pick a side: the corner or sail route into the sideline hole on the half-field side, or underneath and to the flat on the quarters side. Crucible's Hitch reads it as a split field: the half-field side like Cover 2 Tampa, the quarters side with a Curl/Flat/Hook read. ## Common Questions ### Why is it called Cover 6? It is quarters (Cover 4) on one side and a two-deep half-field side on the other, so coaches count it as 4 plus 2. ## Concepts to Rep Against Cover 6 Passing concepts Crucible drills against Cover 6, most common first. - ![Curl diagram](https://www.crucibletech.com/playbook/img/football_11v11/concepts/curl.thumb.webp) Curl Diagonal / Curl - ![Hitch diagram](https://www.crucibletech.com/playbook/img/football_11v11/concepts/hitch.thumb.webp) Hitch Seam / Hitch - ![Dig diagram](https://www.crucibletech.com/playbook/img/football_11v11/concepts/dig.thumb.webp) Dig HB Option / In - ![Slant diagram](https://www.crucibletech.com/playbook/img/football_11v11/concepts/slant.thumb.webp) Slant Diagonal / Slant - ![Option diagram](https://www.crucibletech.com/playbook/img/football_11v11/concepts/option.thumb.webp) Option Option / Go - ![Boot diagram](https://www.crucibletech.com/playbook/img/football_11v11/concepts/boot.thumb.webp) Boot HB Option / Bow - ![Tosser diagram](https://www.crucibletech.com/playbook/img/football_11v11/concepts/tosser.thumb.webp) Tosser Lookie / Slant - ![Snag diagram](https://www.crucibletech.com/playbook/img/football_11v11/concepts/snag.thumb.webp) Snag Corner / Snag + 21 more in Crucible ## Plays You Can Practice Against Cover 6 Every one of these is in Crucible, run against Cover 6 so you learn where the ball goes before you see it live. - ![Branch Dig diagram](https://www.crucibletech.com/playbook/img/football_11v11/plays/branch-dig.thumb.webp) Branch Dig - ![Branch Slope diagram](https://www.crucibletech.com/playbook/img/football_11v11/plays/branch-slope.thumb.webp) Branch Slope - ![Cafe Stop diagram](https://www.crucibletech.com/playbook/img/football_11v11/plays/cafe-stop.thumb.webp) Cafe Stop - ![Cruise Option diagram](https://www.crucibletech.com/playbook/img/football_11v11/plays/cruise-option.thumb.webp) Cruise Option - ![Curl diagram](https://www.crucibletech.com/playbook/img/football_11v11/plays/curl.thumb.webp) Curl - ![Curl Hook diagram](https://www.crucibletech.com/playbook/img/football_11v11/plays/curl-hook.thumb.webp) Curl Hook - ![Curl Juke diagram](https://www.crucibletech.com/playbook/img/football_11v11/plays/curl-juke.thumb.webp) Curl Juke - ![Curl Snag diagram](https://www.crucibletech.com/playbook/img/football_11v11/plays/curl-snag.thumb.webp) Curl Snag + 23 more in Crucible ## Related coverages - ![Cover 4 diagram](https://www.crucibletech.com/playbook/img/football_11v11/coverages/cover-4.thumb.webp) Cover 4 31 plays to rep against - ![Cover 2 Tampa diagram](https://www.crucibletech.com/playbook/img/football_11v11/coverages/cover-2-tampa.thumb.webp) Cover 2 Tampa 31 plays to rep against Learn to read Cover 6 at game speed Crucible is a quarterback simulator: you take the snap, read the coverage and make the throw, then see exactly what you missed.
