jdr asked me what my 5 favourite drills are, since I called for a fatwa on dump-swing-score.
I haven't done an exhaustive look through the drills I know, so here are just 5 that I like. In no particular order.
Thrower marker drill aka 3 man drill
Anecdotally, I have marked the disc better in games where I do this drill before the game. I also like doing it with a one-way force and copping pushups for getting broken. Also, see an animation here.
This drill teaches a guarder to constantly get into good position relative to a cutter. It is a bit like mirror drill except the guarder aims to always be between the cutter and a thrower standing at one cone. There is a pushup for the guarder, each time the cutter gets on the wrong side of the guarder, announced with a "bzzzt". And on 10 seconds the thrower has to throw to the cutter. Extra pushups if the disc is caught - more if the disc is caught "under".
A good drill for introducing the idea of a cup, and for learning how to throw through a cup. Has the disadvantage of a bit too much standing around, so I prefer to run it with no more than 10 players.
This drill has a thrower, a cutter and guarder. From a stack, the cutter moves out horizontally to a cone. They can then only cut vertically: either cut in, cut out, cut in then out, or cut out then in. They only have "one chance" to change direction. The guarder tries to get the D. This helps the cutter with sharp 180 degree cuts and communication with a thrower. It also helps the guarder judge the threat of an in cut versus an out cut, and judge who the thrower is.
3 man weave
A simple way to warm up, get some throws in and practise give-go skills. Doesn't require any cones to set up.
The first 4 drills let O and D practise their skills simultaneously. And a drill with D is more realistic.
Of course, I really like scrimmages with rule modifications, but I don't know if that is a drill. Examples are here and here. Hmmm, that looks like another post. "Drill" seems to imply rigidity, rotating strictly through the roles and a sharp focus on one skill, unlike a game/scrimmage.
Aah, I've been meaning to compile the ideas of others and my ideas into a central AFDA resource - a handbook or wiki or database or some combination. I think having it easily printable is valuable. Drawing on what is out there. Who wants to help (contribution or organisation)?
