Drills I like:
- 3 on 3 on a mini-field. Lots of touches, cutting, and high stall count passes, no chance to hide.
- Seegerball or any of its variants. Any game involving two teams, a field, and multiple balls/discs. Teaches fast break offense, O and D with man advantages, and evaluating risky strategies. And fun, too, especially if there is violence involved.
- Some version of the cutting drill. This is the only conventional drill on the list, where you have lines of people doing about the same thing. I like it because it focuses on a technique that includes decision-making rather than just mechanics.
Drills I hate:
- The endzone drill. Dump, swing, loonnng cut from the back, repeat. Especially bothersome when you add defense or require x completions in a row. ALTERNATIVE: split up into two teams, flip the disc 10 yards out, one team is on O and the other is on D.
- The endzone drill. I hate it that much, it deserves two places.
- The comeback drill. Two lines, one player cuts, throw the disc. Zook! Thwack! It's only mildly better when you cut at an angle. Barely tolerable when a marker is added. ALTERNATIVE: poke your eye with a needle.
- Any drill where you add an incentive (an extra minute on an Indian run for everyone on the team, say) that changes the way people do the drill. For instance, take the drill where one player runs back and forth for 90 seconds and the other throws him leading passes. Without that incentive, I try to work on useful but difficult passes, say, pretending the mark is all over me and I have to stretch out to get the pass off. But with that incentive, I'm much more likely to take the "100%" pass that I don't need to work on. ALTERNATIVE: reduce the penalty, or eliminate it while stressing the mental images that make the drill good.
Good drills: get lots of reps, offer a chance to reflect on whether you did the right thing or not, require decision-making, fatigue you, mimic some aspect of ultimate.
Bad drills: have lots of down time, have poorly-designed incentives, have an easy way to get around the purpose of the drill, simulate something artificial.
Maybe it's just the way that my mind works, but I can instantly see the flaws in and ways to get around a drill that someone else designs.
