Jackson sets a flat mark. The wall should be 10-15 yards deep(depending on wind). The distance between the four wall members should be small enough that no throws are allowed through. The G-Spot should be several yards behind the wall, patrolling sideline to sideline to discourage/prevent short hammers and scoobers. He also communicates with the wall. Elbow Deep should has the 'last-back' responsibility, should shade to the disc-side of the field and discourage/prevent any deep throws or bailout hucks.
As the disc swings to the other handlers, the wall adjusts with it. Jackson should follow the disc and set a flat mark as soon as possible and start counting. The disc-side Outie should position themselves to not allow any throws around the outside.
The Outie can move with the incoming popper a little to discourage the throw , but do not get sucked in too far.
Don't pursue too long though.
If the Outie follows the popper too far in, they will be out of position and allow a throw past the wall.
Reset.
The far-side Outie is responsible for an entire half of the field when the disc is away from them. They should position themselves to discourage throws across the length of the field.
Reset.
Do not bite on swings to the far-side handler, if you go for it and miss, the whole zone falls apart.
And they will score.
Reset.
The Innies should do the same thing as the end when a popper comes into their space. Stay with them just long enough to discourage a throw, but not so long as to leave a hole open.
Over the top, inverted, low-percentage throws are okay. As a zone, we WANT the offense to throw those. They give the us a better shot to D them.
Reset.
The bottom line for the zone is to force the offense to throw many many short throws.
Our number one goal is to not let anything past the wall. The wall needs to maintain it's distance from the disc, 12+- yards.
Let the offense swing the disc all day long, they'll drop it eventually.
If the Elbow-Deep thinks that the zone is being broken, they will loudly call "FIRE!" which NEEDS TO BE ECHOED by everyone. When "Fire!" is called, we switch to man defense. In this case, we are forcing flick when "Fire!" is called.
Everyone needs to find the person close to them as quickly as possible, if there is a deep threat, go guard them.
After we go "Fire!" into a man-defense, we will not go back to zone for that point.
