Cover 8
Cover 2 Field / Cover 4 Boundary
Cover 8 is the inverse of Cover 6: Cover 2 (halves) to the wide side of the field and Cover 4 (quarters) to the boundary. From a two-high pre-snap shell, it looks identical to Cover 4, Cover 2, or Cover 6, the QB cannot distinguish the actual coverage until post-snap. The field side gets two-deep protection to handle the wider space, while the boundary side uses quarters to pattern-match in the compressed area where receivers have less room to operate.
Defender Responsibilities
Plays Cover 2 technique on the field side, jams #1, funnels inside, sinks to the flat. Does not have deep responsibility. The field-side safety takes the deep half behind him. The wider field gives more room for the jam-and-sink technique.
Plays quarters technique on the boundary side, keys #1, carries vertical, pattern-matches off the route. The compressed boundary space makes it easier to stay on top of routes. Has the boundary-side safety's inside quarter behind him.
Plays the deep half on the field side in Cover 2 technique. Owns everything deep from the hash to the field sideline. The wider space demands range and speed to cover the entire half. Keys #2 to QB.
Plays the inside quarter on the boundary side in quarters technique. Keys #2 boundary, if #2 goes vertical, carries him. If #2 goes short, robs underneath or helps the CB on #1. He's paired with the boundary CB to cover half the deep field in two pieces.
Hook-curl zone on the field side. Plays with standard Cover 2 underneath technique. Must handle the wider zones created by the field side and rally to crossers.
Anchors the middle hook zone. Must recognize the asymmetry and adjust, concepts from the Cover 2 field side create different windows than concepts from the quarters boundary side.
Underneath on the boundary/quarters side. With quarters over the top, the SAM has deep help inside and out. The compressed space makes his job easier but floods can still stretch him.
Vulnerabilities
- !! Identifying the split exposes the scheme
- !! Field-side deep seam (Cover 2 weakness)
- !! Boundary quarters seam between CB and SS
- ! Motion/shift to test the coverage boundary
- ! Post-wheel to the field-side Cover 2
Best Attacks
Pre-snap motion to identify which side is Cover 2 vs quarters. Attack the field side with post-wheel or smash (Cover 2 weaknesses). Attack the boundary with seam routes between the CB and SS quarters. Flood the boundary between the two coverage styles.
