Defense
The side of the ball nobody covers well. Coverages, pressure and the answer to what everyone runs.
Defense is three decisions, made in this order: whether each player takes a person or an area, whether you send anyone at the quarterback, and what you change when one concept keeps beating you. Get the first one wrong and the other two cannot rescue it, which is why coverage leads this page instead of pressure.
That order matters more on defense than it does on offense. A sweep is defended differently in man than in zone, and a rush that works against a quarterback standing still gives up the edge against one who runs. There is no list of defensive calls that holds up independently of what your coverage is doing behind it, which is why most defensive advice written for youth coaches falls apart on contact.
If you are here because something beat you on Saturday, skip the theory and go to the Stop the… shelf. Those cards are named after what happened to you rather than after the scheme that answers it, so you can find yours without knowing the vocabulary first.

Coverages
Start at the top if you have never coached defense before: where everyone stands, then whether each player takes a person or an area. The numbered shells underneath are versions of those two ideas. Pick a format above and each one becomes the version written for that game.

- Where everyone lines upBefore any coverage: the spots your players stand in every single down, and why each one is there.Where everyone stands
- Man coverageEvery defender is responsible for one player and goes where that player goes.ManNo help
- Zone coverageEvery defender is responsible for one patch of grass and covers whoever comes into it.2 deep3 hook

- Cover 0Man coverage with nobody left behind it. When the rush is the whole plan.Man underneath
- Cover 1Man coverage with one player staying deep to clean up what gets past.1 deepMan underneath

Stop the…
Every card is a thing that beat somebody last Saturday, in the order it actually happens. Find what got you and start there.
- Stop the sweepOne player runs wide and outruns everyone. Contain has to beat speed, and that is a spacing fix.Fix lives in the flat
- Stop their best playerEvery team has one, and at this age they get the ball every down. Where to put your best defender, and where not to.Fix is a matching rule
- Stop the quarterback runningNobody rushed, so the quarterback just walked forward. The single most common way a youth defense gives up yards.Fix lives in the hook
- Stop the deep ballEveryone came forward and nobody stayed behind it. One rule fixes this, and it is not a coverage.Fix lives deep
- Stop the quick throwsThe ball is out in a second and a half to somebody standing three yards away. Rushing harder makes it worse.Fix lives in the flat
- Stop the rub routesYour defenders keep running into each other and you cannot work out why. Switch, do not chase.Fix is a matching rule
- Stop MeshThe two crossing routes that make man coverage collide. The most-run concept in flag football.Fix lives in the hook
- Goal line defenseNo grass behind you, so the deep help you normally rely on has nowhere to stand.Fix lives in the hook
Fronts and pressure
Rushing is optional, and it costs you a defender every time. Start with whether, not with how many.
- Should you rush at all?You do not have to. Plenty of good youth defenses never send anybody, and here is when that is the right call.1 rushing2 off it
- The seven-yard rush lineWhere a rusher has to start, how it is marked, and the leagues that move it. Get this wrong and it is a free first down.1 rushing3 off it
- How many to rushNought, one or two. Each extra rusher is one fewer defender in coverage, and that trade is the whole defense in 5v5.2 rushing3 off it
- Who should your rusher be?Not automatically your fastest player. The job needs discipline more than speed, and picking wrong is why the quarterback keeps escaping.1 rushing3 off it
- Keeping them from getting outsideRushing straight at the quarterback opens the sideline. What contain means, in a sentence you can say to an eight-year-old.2 rushing2 off it
- Blitz looksStanding somewhere that suggests you are coming, then not coming. Free pressure once your players can be trusted to fake it.3 rushing2 off it
- QB spyOne defender whose only job is the quarterback, ignoring every route. The answer to a quarterback who runs.1 rushing3 off it
- What a front isWhere your linemen and linebackers stand before the snap. A different question from what they do after it.5 on the ball2 off it
Other common coaching questions
The rules a defensive coach ends up arguing about, answered plainly.
- Are pick plays legal?The rule the offense is testing, and what you can actually call.NFL FLAG 2025 · Receiving
- What counts as a legal flag pull?Where the contact line is, what a strip is, and what the official is actually watching for.NFL FLAG 2025 · Flag Pulling
- Is flag guarding on us or on them?The penalty coaches argue about most. It is on the ball carrier, and here is what it looks like.NFL FLAG 2025 · Running · rule 10
- Can you rush every down?Usually yes, sometimes no, and a handful of leagues cap how many rushes you get in a half.Coaching judgement, not a rule
- Is the ball dead if it hits the ground?Almost always yes, which means no fumbles and no scooping it up. The rule that surprises every new coach.NFL FLAG 2025 · Dead Ball · rule 8a
- Can you return an interception?Some leagues let you run it back. Plenty blow it dead where you caught it.Coaching judgement, not a rule
- How do you teach defense to 5 and 6 year olds?Not with a coverage. Three ideas they can hold, and the order to give them in.Coaching judgement, not a rule
