Dagger
Clear-out verticals open the dig over the middle

Dagger uses two clear-out verticals to empty the intermediate middle for a dig crossing underneath. The outside receivers push the corners deep and pin the safeties to their landmarks, while the slot runs a dig at 12 yards into the hole the verticals just vacated — behind the linebackers, in front of the deep coverage. It is a staple answer to both Cover 2 (the dig splits the halves in the MOF hole) and single-high zone (the vertical forces the hook defender to carry, opening the in-cut window). It pairs beautifully with play-action to hold the underneath defenders an extra beat.
Reads
5 ROUTESTap a route to trace it on the field.
Read progression
The dig is the primary read as it crosses behind the hook defenders. If a hook player sinks under it, the curl opens at the sticks. The clear-out go is an alert against a flat-footed corner; the flat is the outlet.
Why it works
The two clear-out verticals occupy the corners and pin the safeties deep, leaving nobody responsible for the intermediate middle. The dig crosses into that hole at 12 yards behind the linebackers, and the curl and flat give the QB immediate answers when the defense sinks underneath the dig.
Conflict defender
The hook defender and the play-side safety: the clear-out gos pin the safety deep, and the hook defender has to choose between sinking under the dig and widening to the curl

Dagger vs coverages
9 RATED- Cover 2Beats it
The clear-out gos pin both half safeties wide and deep, and the dig crosses into the hole at 12 yards behind the hook linebackers and in front of the safeties — the intermediate middle belongs to no one in Cover 2.Show reasoning
Conflict defender. Deep-half safety (dig side)
Why the offense wins. The clear-out gos pin both half safeties wide and deep, and the dig crosses into the hole at 12 yards behind the hook linebackers and in front of the safeties — the intermediate middle belongs to no one in Cover 2.
Key adjustment. Sink the MIKE to depth in the middle hole to take away the dig window.
- Cover 3Beats it
The vertical lifts the deep-third corner and forces the hook defender to carry it to depth, opening the in-cut window at 12-15 yards behind the underneath drops and in front of the FS — Dagger is taught as a single-high answer for exactly this reason.Show reasoning
Conflict defender. Hook/curl defender (forced to carry the vertical)
Why the offense wins. The vertical lifts the deep-third corner and forces the hook defender to carry it to depth, opening the in-cut window at 12-15 yards behind the underneath drops and in front of the FS — Dagger is taught as a single-high answer for exactly this reason.
Key adjustment. Rotate late to Cover 1 with a rat, or buzz a safety into the hook so a hole player sits in the dig window.
- Tampa 2Beats it
The clear-outs hold both half safeties, and the Tampa 2 MIKE bails for the deep middle at the snap — the dig settles at 12-15 yards in the exact window the pole-running MIKE vacates.Show reasoning
Conflict defender. MIKE linebacker (middle-third zone)
Why the offense wins. The clear-outs hold both half safeties, and the Tampa 2 MIKE bails for the deep middle at the snap — the dig settles at 12-15 yards in the exact window the pole-running MIKE vacates.
Key adjustment. Have the MIKE sink to the dig window first and let the half safeties cap the clear-out gos.
- Cover 1Edge
The clear-out gos lift both corners and the single-high safety stays glued to the deep middle, leaving the dig one-on-one against a trailing man defender with no inside help — the dig is one of the hardest routes to match without a rat in the hole.Show reasoning
Conflict defender. Man defender trailing the dig
Why the offense wins. The clear-out gos lift both corners and the single-high safety stays glued to the deep middle, leaving the dig one-on-one against a trailing man defender with no inside help — the dig is one of the hardest routes to match without a rat in the hole.
Key adjustment. Drop the MIKE into the hole as a rat/robber to wall the dig at its break point.
- Cover 2 ManEdge
The dig breaks across a trailing man defender with the half safeties too deep to help at 12 yards; the clear-out gos hold the corners outside.Show reasoning
Conflict defender. Linebacker matched on Y receiver
Why the offense wins. The dig breaks across a trailing man defender with the half safeties too deep to help at 12 yards; the clear-out gos hold the corners outside.
Why the defense wins. Two-deep safety help can drive down on the dig once the gos clear the corners.
Key adjustment. Have the half safety on the dig side drive down on the in-breaker once the go clears his corner.
- Cover 6Toss-up
Cover 6's split-field rules let each side handle the routes within its rules; neither shell is generally vulnerable to Dagger.Show reasoning
Conflict defender. Inside linebacker (hook zone)
Why the offense wins. The dig crosses from the quarters side into the Cover 2 side, where the half safety is deep and the hook defenders are spot-dropping.
Why the defense wins. Cover 6's split-field rules let each side handle the routes within its rules; neither shell is generally vulnerable to Dagger.
Key adjustment. Have the MIKE sink to the dig's depth; the quarters safety on the dig side drives it as his #2 in-breaker.
- Cover 0Tough
Zero pressure arrives before the dig breaks at 12 yards, and the clear-out gos pull nobody when there is no safety to move.Show reasoning
Conflict defender. MIKE linebacker (man on the slot or sixth rusher)
Why the offense wins. If the protection holds one extra beat, the dig breaks behind the blitz into a completely vacated middle of the field with no safety alive.
Why the defense wins. Zero pressure arrives before the dig breaks at 12 yards, and the clear-out gos pull nobody when there is no safety to move.
Key adjustment. Bring the sixth rusher; the dig needs 12 yards of stem and the pressure arrives first.
- BracketTough
If the dig runner is bracketed, the dig is doubled at its break and the route is dead.Show reasoning
Conflict defender. Bracket on the dig runner
Why the offense wins. If the bracket is on the outside clear-out, the dig from the slot still runs against a single trailing defender.
Why the defense wins. If the dig runner is bracketed, the dig is doubled at its break and the route is dead.
Key adjustment. Put the bracket on the dig runner so the in-breaker is doubled at its break.
- Cover 4Avoid
The quarters safety keys #2 and drives the dig the instant it breaks inside, while the corners carry the clear-out gos man-to-man; every window in the progression is capped.Show reasoning
Conflict defender. Play-side quarters safety (keys #2)
Why the defense wins. The quarters safety keys #2 and drives the dig the instant it breaks inside, while the corners carry the clear-out gos man-to-man; every window in the progression is capped.
Key adjustment. Have the safety drive the dig as his #2 in-breaker while the corners carry the gos; the MIKE walls the curl.
