I had a whole post ready to reply to this with, and then my internet got screwy... ah well.

Anyways, we deal with turnover by having our seniors delegate some of their work to sophomores and freshmen, so that people get more experience, and also encourage people to learn new skills over the off-season (programming, chains, etc.). The off-season practice also gives a redundancy, so if our lead programmer/driver were to get sick, someone would fill in. It seems to work pretty well for us.
