Joshe, I think you have a point here about teaching.
We don't know what Dan was trying to get them to do as a task, and it is not clear from his demo what he is asking them to do. I agree that that he is skiing too fast in the fall line to do a clear and effective demo. Almost no one in the group is capable of that. Unless Dan were trying to teach the group to ski these moguls very slowly but continuously, most of the group is too over-terrained to do effective teaching. The skiing is too defensive with the skiers falling back on their old bad habits, and learning goes out the window. You can learn to ski it slowly, then dial up the speed as you are capable. Otherwise, they should be somewhere else where more success at the assigned task is possible.
There is a big split in abilities within the group.
The most striking thing to me is the lack of feedback. I kept waiting for the nugget, but it never came. When I ski with Jeb, there is always a nugget, usually 10 words or less, and it is exactly what you need to know. Short, sweet, and precise.
All that said, I choose to look at the clip as an example of ineffective teaching, for whom the coach happens to be Dan Egan.
