5v5 Defense
The best starting defense in 5v5 flag football is three deep and two underneath, with nobody rushing. Five defenders against four eligible receivers leaves exactly one spare player, and the whole of 5v5 defense is deciding where he stands: deep as insurance, on their best receiver, or after the quarterback.

What changes at 5v5
One spare defender, and every call spends him
Four receivers need four defenders, so a rusher, a spy or a second safety all come out of the same single player. That is why Cover 4 is not offered at this size: four deep out of five leaves one man to cover the entire short field.
The quarterback can run
Plain 5v5 lets the quarterback cross the line, so an unrushed passer who sees green grass will take it. Any defense with nobody rushing needs one player told to watch him once he leaves the pocket.
Nobody may block
With no blocking the sweep is a footrace to the corner, and angles beat speed. The outside defender's job is leverage, never the tackle, which makes the run game here a question of alignment rather than strength.

- 1Where everyone lines up in 5v5The two pictures every sound 5v5 defense starts from, and where the spare player goes in each.
- 2Should you rush at all?Plenty of winning 5v5 defenses never do, and this is the decision that sets up every other one.
- 3Stop the sweepThe play that beats more youth defenses on a Saturday than anything else, answered with an angle.
Coverages
Five shells written for five a side: where everyone lines up, then Cover 0 through Cover 3. Quarters and the hybrids need more bodies than 5v5 has, so they are left off rather than greyed.

Stop the…

Fronts and pressure
Rushing is optional here and it always costs your one spare defender. Start with whether to send anybody, then who, then 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
