Setup - only three people involved.
Middle player throws to side and immediately cuts forward (give & go).
Side player pops the disc up to the initial thrower.
Thrower fakes a pass infield with a big pivot; side player moves behind for the dump.
Dump pass.
New middle player throws to the other side and follows her pass. New side player moves out a bit.
Pop pass to middle player.
Fake infield throw with big pivot; side player moves to dump position.
Coaching points: 1. Might find that the drill tends to get quite cramped, so encourage the side players to move out if necessary. If it's really windy, though, you may need to keep things fairly small to ensure a high completion rate.
Motivation for the drill: imagine a cup. This is how it normally works:
Thrower passes to side handler; cup expands to (a) stop the return throw, and (b) stop the upfield throw. There are big holes between the cup players, but the thrower is too far away to take advantage of them.
Cup moves in & applies pressure.
So let's try something different.
Thrower throws to side handler and immediately cuts forward. If this movement is quick the cup will be unable to get in front.
Cup is still moving but the initial handler is running inside the cup.
Side handler give disc to initial handler. Now the cup is out of position; if the thrower can take advantage of it before they react, we can break through.
Pivot towards the gap; a big pivot is your friend here. You have one chance to throw through to a handler, or to a popper. Side handler must move back to dump position in case there is no one to throw to; we will go back to the dump/swing instead.
Broken!
Further coaching points: 1. You might want to start with this motivation for the drill, and then split the group into threes for the handler part of the drill, with no defence, You can run through the defence+offence scenario using cones. 2. If the number of players isn't divisible by three, you can do some groups of four. In this case, after the dump, there will be a sideways swing with no give-and-go, followed by the sideways/upfield swing + give-and-go. 3. Let people do the drill for a bit, to get the hang of it, and then bring them back in to cover the points below. 4. The pop pass (step 3) should not be in front of the running player, because the defence could reach out and grab it. Instead, it should be to the player's side, so her body is between the disc and the defence. The cutting player should slightly turn her body and use her hands to call for the disc in this position. 5. Really emphasise fluidity on the give-and-go. A pause between throw and run will let the defence adjust. 6. Throws from the centre should pretty much all be backhands. A bakchand lets you pivot towards your receiver, make the throw, and then accelerate from your front foot. 7. When pivoting towards the centre of the field, after receiving the pop, you should: (i) Stand upright, (ii) spin to face the new direction, (iii) step out. This is because the defence are very close to you; if you move suddenly without looking you might headbut someone in the face.
