What is the Four Verticals concept in 11v11 flag football?

Coach Ray Carroll12 seasons, youth and rec flagUpdated
The short answer

In 11v11 football, Four Verticals runs the outside receivers on go routes at twenty and the inside two on seams at seventeen and fourteen, with the back releasing to the flat at four. The depths are staggered deliberately so four receivers do not arrive in one horizontal band and hand a single defender two of them.

Against single-high the safety has two seams and one of him. A man corner cannot run with a vertical forever. The back checks down if nothing breaks. Depths are staggered on purpose so four receivers do not arrive in one horizontal band and share defenders.Open this play in the designer →

Why Four Verticals works in 11v11

  • The depths are staggered on purpose

    Twenty, twenty, seventeen and fourteen. Four routes arriving at the same depth occupy one band and a single defender can influence two of them; breaking them apart means each route arrives in its own window. The flag versions run flatter depth spreads because they have fewer bodies to separate.

  • Against single high the read is a single defender

    With one deep safety and two seams inside, the safety is wrong whichever he takes. That is a cleaner one-defender read than any smaller format offers, where the deep structure is usually two defenders splitting the field.

  • It is decided by counting, not by reading

    Two deep defenders against four vertical routes means two receivers are uncovered deep. One deep defender means three are. The quarterback does the arithmetic before the snap and throws to the answer, which removes almost all of the in-play decision-making that gets young quarterbacks into trouble.

  • Nobody covers a vertical route forever

    A defender running stride for stride with a receiver has to turn and find the ball at some point, and the moment he turns he stops running. Even a coverage that is technically correct produces a throwing window if the route is run at full speed.

  • Staggered depths stop the routes from sharing defenders

    If four receivers arrive at the same depth at the same time they occupy one horizontal band and a single defender can influence two of them. Breaking the depths apart, which every version of this concept does, means each route arrives in its own window.

How to read it

  1. 1

    Count the deep defenders before the snap

    One deep defender, two, or none. That number tells you how many of your four are uncovered and roughly where they are. Do this every snap, not only when you have called this concept.

  2. 2

    Look at the deepest defender's first step

    Whichever way he leans, the vertical on the other side is the throw. Against a single deep defender this is the whole play and it happens in the first second and a half.

  3. 3

    Throw it before the rush arrives

    Vertical routes take time, which is the concept's only real cost. Decide early and let it go rather than waiting for a receiver to get further open.

  4. 4

    Take the checkdown without regret

    If the coverage is genuinely correct, somebody underneath is uncovered because everyone else went deep. Taking that is not a failure of the call, it is the call working as designed.

What changes in 11v11

  • The depths are staggered on purpose

    Twenty, twenty, seventeen and fourteen. Four routes arriving at the same depth occupy one band and a single defender can influence two of them; breaking them apart means each route arrives in its own window. The flag versions run flatter depth spreads because they have fewer bodies to separate.

  • Against single high the read is a single defender

    With one deep safety and two seams inside, the safety is wrong whichever he takes. That is a cleaner one-defender read than any smaller format offers, where the deep structure is usually two defenders splitting the field.

When not to call Four Verticals

  • It is a shot, not a base call

    Four Verticals asks for time and produces an incompletion more often than a short concept does. It belongs on first down and on downs where an incompletion is survivable, not on third and short where you need the chains moved.

  • Two capable deep defenders can take it away

    Against a defense that genuinely plays two deep and whose safeties are disciplined, the honest read is often the checkdown. If that happens twice in a row, the concept has told you something and the next call should be underneath.

Related questions

What is Four Verticals in football?
Four receivers running vertically at once against a defense with fewer deep defenders than that. Count the deep defenders before the snap, work out which route is uncovered, and throw it before the rush arrives.
Why are the seam depths different on Four Verticals?
So the four routes do not arrive in the same horizontal band. If they did, one defender could cover two of them. Staggering to twenty, seventeen and fourteen gives each route its own window.
Is Four Verticals good against Cover 2?
It is workable but not ideal: two deep defenders against four verticals still leaves someone one-on-one, but the windows are tighter. Against genuine two-deep with disciplined safeties, expect the checkdown to be the honest answer.
