It IS a good thing.So what you are saying is Grundy Center will of had 6 plus years of success (most schools would kill for that) and now some other teams will get a chance for some success? How is this not a good thing? Also, having a couple of subpar classes really isn't the end of the world. If GC has solid coaches it'll be just fine.
All I'm saying is that they shouldn't have to move up again as part of some promotion/relegation simply because they've been successful.
Smaller classes are so different than larger ones in having a consistent talent pipeline.
