kitten,
I'm fond of the good old days as well. It's nice when a team and a coach can grow together.
In MPSC's defense, cht is right. Many high-level clubs now have paid coaches coaching multiple teams, and many put a 2-year limit on the relationship because:
1. It's good to expose kids to new ideas, tactics, philosophies.
2. Some coaches do very well coaching in a certain gender and age range.
