Where does everyone line up on defense in 5v5 flag football?
In 5v5 flag football the defense lines up in one of two pictures: three deep and two underneath, or two deep and three underneath. Four eligible receivers against five defenders leaves exactly one spare player, and where you stand him is your defense. Everything else is technique.
Why the alignment decides the down in 5v5
Five defenders is four plus a decision
Four of your players are accounted for before you call anything, because the offense has four eligible receivers. The fifth is the whole conversation: deep as help, in the middle as a robber, or on the line as a rusher. Every 5v5 defense on this site is one of those three answers.
Depth costs nothing here
There is no line to hold and no run fit to fill, so nobody has to start shallow. Youth defenses give up almost all of their long touchdowns to a defender who lined up at three yards because it felt aggressive, and the fix is free: start at six and let the short throw be completed in front of you.
You get one look and no rotation
Eleven players can show one shell and roll into another after the snap. Five cannot: there is nobody spare to disguise with, so whatever the offense sees before the ball moves is close to what it gets. That makes lining up the same way every snap more valuable, not less.
It is the only part of defense you control with time on the clock
Coverage is a reaction to something that has already happened. Alignment is a decision made while nobody is moving, which is the one moment in a defensive play where a coach can be certain of the outcome. A team that lines up correctly has already won the part of the down it can win.
Depth is free speed
Most touchdowns given up by youth defenses are thrown over a defender standing too close to the line. Two more yards of depth costs nothing, cannot be taken away by a faster receiver, and converts the throw that beats you into the throw in front of you.
Lining up the same way removes the busted play
The most common disaster in youth football is not a beaten defender, it is two defenders in the same place and nobody in another. A defense with one alignment it can get to every snap has removed that failure, and everything after it is a coaching problem rather than a chaos problem.
Before and after the snap
The same call twice. What a coverage IS lives in the difference between these two pictures, not in either one of them.
- The alignmentWhere everyone lines up at 5v5 before the snap: the alignment and the rush, with no coverage drawn.
Where everybody stands, and who is coming. This is all an offense sees before the ball moves, which is why a defense that tips its coverage from the alignment has given away the only thing it was hiding.
- The coverageWhere everyone lines up at 5v5 after the snap, with every zone drawn and labelled.
The same men a beat later, with what each is responsible for. Every seam and every soft spot on this page is a gap between two of these shapes.
How an offense attacks an alignment in 5v5
Find the spare defender
Count the defenders who are deeper than everybody else. One means the middle of the field is open behind a beaten defender; two means the sideline throws are there; none means somebody is coming and the ball has to be out.
Make the widest defender wrong
With five players there is always a defender responsible for two things at once, and he is usually the one outside. Put one receiver on a flat route and another behind him, and whichever he takes is the completion.
What a bad alignment gives up
An alignment that announces the call
If the safety walks down every time you blitz, a quarterback who has watched one series knows what is coming. Line up the same way every snap and move afterwards, rather than lining up in the answer.
A formation you have not practised against
Trips, bunch and empty all exist to make a defense re-align in a hurry. If the answer is being invented on the field, the snap arrives before it is finished, and the busted play the alignment was supposed to prevent happens anyway.
