Cover 3 Zone (7v7 flag football defense)
Three defenders split the deep field into thirds, three more guard the short area from sideline to sideline, and one rusher chases the quarterback. It is the most common base zone in 7 on 7 because it keeps the big play in front of you and still has enough short defenders to rally to quick throws.
Each defender's job
- RURusher. Start at least 7 yards off the ball with a hand raised and go for the quarterback's flag. Watch for a handoff to R and pull that flag instead if the ball goes there.
- LBGuards the short left side, the curl and flat area from the sideline in to the hash. Stay under Y and X's short routes and come up on any run or screen to the left.
- MGuards the hook area in the middle, 4 to 8 yards deep, right in front of the center. Take away C and any in-route across the middle.
- NBGuards the short right side, the same job as LB. H and Z are your side, so sink under their short routes.
- LCGuards the deep left third. Drop at the snap and stay deeper than X and Y.
- FSFree safety. Guards the deep middle third. Nobody gets behind you, and you help on any deep throw toward either side.
- RCGuards the deep right third. Drop at the snap and stay deeper than H and Z.
When to use the Cover 3 Zone
Use it as your base 7 on 7 defense, against teams that like to throw deep, and any time you are not sure what the offense does yet. This version has one rusher starting 7 yards back. Many 7 on 7 leagues use a pass clock and no rush at all, so check your league's rules.
Strengths
- Three deep defenders make the long pass very hard.
- Three short defenders cover the whole width, so quick throws are met by a defender right away.
- Every player has a clear area, and the same rules work against any formation.
Weaknesses
- Four receivers going deep outnumber the three deep defenders.
- The seams, the lanes between a deep third and the middle third, stretch the deep defenders apart.
- The area just behind the short defenders, 10 to 14 yards deep over the middle, is hard to cover when the free safety is pulled away.
How offenses beat it
These plays from our playbook attack the soft spots of the Cover 3 Zone. Run them against your own defense in practice so your players learn what it looks like.
Four receivers run deep against three deep defenders. The free safety cannot cover both inside verticals, so one of them is open in the seam.
H runs the seam and pulls the deep middle defender, and Z runs a 12-yard dig right behind the hook defender into the space that is left.
Coaching points
- Teach the deep defenders to backpedal until the QB throws, then break on the ball. Staying deep is the whole job.
- The short defenders should sink to about 8 yards and read the quarterback. When the QB winds up, drive toward the throw.
- When two receivers run deep up one seam and one sideline, the deep defender on that side takes the outside one and the free safety takes the inside one. Walk through this in practice.
- Everyone runs to the ball after the catch. A short catch should stay a short catch.
Common mistakes
- A short defender follows a receiver deep and leaves a hole underneath. Pass deep receivers off to the deep third.
- The free safety guesses and jumps a route early, leaving the deep middle open.
- The rusher ignores the back and a quick handoff goes right past.
Adjustments when the offense attacks it
- If four verticals keeps working, move the hook defender back to guard the deep middle on long-yardage downs, which gives you four deep defenders.
- If Dagger or deep in-routes hurt you, tell the hook defender to sink deeper, to about 10 yards, when a receiver runs straight up the seam.
- If the offense completes quick outs, have LB and NB widen toward the sidelines before the snap.
