I think a few things are important when you’re trying to teach or learn a new zone. The first is to have a clear idea of what the purpose or goals of that particular zone are; sometimes, you are trying really hard to contain any disc movement and force the offense to make a ton of throws. Other times, you want to force them into a tougher throw and take a risk at making a play on it.
Then, I’ve found it helpful to try to isolate different positions in the zone with some sort of drill. Tube (4 defenders vs 3 offenders on a small, narrow field) can be a good way of getting people into a “zone” type of mindset, and is one I’ve often used as a warm up for zone-heavy practices. There are some other types of drills that can allow players to work more on a cup/front wall type of position, vs a wing/short deep position.
Finally, I think it’s important to be willing to make changes to certain zone strategies as necessary. Being able to film games or practices can be very useful for this, but even just having defensive lines bring it in and discuss successes/failures immediately after points can work. Especially if you are trying out a new zone, you may find that things don’t always work out the way you thought they might, so it’s important to be able to look at things impartially and make changes as necessary (for example, changing the way you trap, or where on the field you trap, to avoid the trap getting broken too easily).
Hope that helps!
