6v6 Defense
The best starting defense in 6v6 flag football is the same three-deep shell 7v7 teams run, one player lighter underneath. Six defenders is the first size at which quarters becomes playable, and the field divides far more like seven than like five, which is why each numbered shell on this hub opens its 7v7 write-up.

What changes at 6v6
The first size where quarters is real
At five a side four deep leaves one player for the whole short field. At six it leaves two, which is thin but playable against a team that only throws deep. Cover 2 Man and match coverage still need a seventh defender and are left off this hub.
Your coverage pages are the 7v7 ones
This hub borrows the 7v7 write-ups for its numbered shells rather than inventing a thinner copy of them; read them with one fewer underneath defender in mind. Man, zone and the choice between them open their own format-free pages.
Check your league before you plan a rush
There are no pressure pages written for six a side, because the rush depends on the rulebook rather than the headcount. The pages cover plain 5v5 and NFL Flag rules; start from whichever matches the one you were handed.
Start here
- 1Cover 3, the base shell to borrowThe balanced arrangement six and seven defenders both start from. Take one player out of the underneath band.
- 2Where everyone lines upThe three levels of a defense, and the names of the areas, before any six-player coverage makes sense.
- 3Stop the quick throwsWritten for seven, and the problem a six-player zone meets first: short throws into the gaps.

Stop the…
Each card opens its 7v7 write-up, the closest size with its own Stop the… pages. Read every fix with one fewer defender to spare than the page assumes.
- 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

Fronts and pressure
Rush rules at six a side depend on the league more than on the headcount. The pressure pages are written for plain 5v5 and for NFL Flag; read the set whose rules match yours.
- 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
