Pioneer only had a few good years when they had an exceptional coach. Tim Spray was there for 7 or 8 years and they were really competitive for a school there size during his tenure. Unfortunately for Pioneer, Tim moved to Wisconsin about three years ago. Since then Chuck Ladow coached them for two years and they were decent but even he has moved on now. That's three coaching changes in a very short period of time and the numbers just aren't there because of it. It's very hard to get numbers out without a coach that has built relationships in middle school and up. The current coach is in his first year there and they only have about 10 kids in the room. I think if he stays for a while and works on his middle school program the numbers will come back and they'll be competitive again but without some stability it's very hard to get numbers out in a small school, especially for a lay coach such has the current coach at pioneer.
As for other programs in general, my guess is it all comes down to what others have said. head coaching changes are hard to swallow even at big schools and if the community isn't behind the new coach or the administration changes and isn't behind the sport anymore things are going to be very difficult.
