I didn't mean to be so negative last time about drills. I was mostly commenting on drills for advanced club teams, not for beginning teams that need to work on basics like catching and 20 yard passes that don't turn over. If that's your team, then it'd be very inefficient to spend much valuable practice time on subtle skills (maybe a little just to get players thinking and to make it fun).
My wife is putting together a women's team and I sat in on their practices this weekend. They had low numbers, so had to do drills and just drills. They ran a nice combination of break-mark throws and cutting to the break mark, with plenty of time for each group of O and D to discuss what went right and wrong and how to improve.
They also did Idris' cutting drill (make a move within 3 steps, decide within 1 or 2 steps whether to continue, and if not go the other way), which went well but suffered a little because the D wasn't that good. (Even when I was running through on D as 3/4 speed, I was still making plenty of mistakes, but I don't think they read the mistakes at all, and instead went through their planned motions. I had read them my new "five rules" of cutting, and they seemed responsive, although I don't know how much they were able to incorporate.
Anyway, I thought of a couple things you could do by yourself with 6-10 discs.
1. Throw long passes to an exact point, or to a small marked-off area (say, 5 yards by 10 yards).
2. Throw successively longer passes. Begin by throwing at a target 30 yards away. Your next throw has to be longer than your first. Continue until you fail. Long passes often fail because you're just throwing to throw them too hard. Most golf shots are not hit at 100%, because they aren't nearly as controllable.
3. Discathon. Set up a course, or go through a sparsely-wooded area. Two discs. Throw one, run after it, throw the second just before you pick up the first.
With two people:
1. Throw and run, pretending you're making specific cuts.
2. Throw in a crowded area with restricted passing lanes, say, a street with a bunch of parked cars, or again, in a sparsely-wooded area, or around the house. This forces you to contemplate the throwing lanes, and will help you figure out how to deal with poachers and cloggers.
3. Throw standing still, pretending you have a marker who occasionally fouls you.
