I disagree with shrinking the number of classes. It seems people want this out of convenience for the media and fans. Wrestling, Track, and Cross Country makes sense to have four classes because they are individual sports that have a team scoring component. Qualified individuals still have a legitimate chance to win a state championship individually. Changing Volleyball and Basketball to four classes just for the convenience of running a tournament and to make it "tougher" because you think it's watered down seems like you're making a decision not in the best interest of the kids. I know basketball and volleyball are a more competitive environment than football from an enrollment standpoint because you're only using 5-6 players instead of 11 or 22 players, but enrollment still matters. If you shrink the number of classes, all you're doing is growing the distance between the top of the class to the bottom of the class. If you're argument is to have more competitive games at the state tournament, wouldn't it make sense to add more classes to make those enrollments closer and have more competitive games that way? Adding more teams to a class doesn't automatically make it more competitive at the top like you think it would.
Your "watered down" problem could be fixed if all classes went to a sub-state format or a true serpentine district seeding method to try and make sure you have the best teams make it to state. Doing districts geographically doesn't get the best teams to state. Unfortunately, there are a lot of schools/districts in the NSAA that don't like that because of "travel" or "expense", but every year we end up with loaded districts and districts that are just taking a sport from a more deserving team.
For example, in C2 this year, there are 4 of the top 16 teams in power points in sub-district C2-9: Arcadia-Loup City (3rd), South Loup (4th), Ravenna (11th), and Amherst (16th). Then there are Cambridge (8th) and Dundy County-Stratton (19th) on the other side of the district in C2-10. Then in sub-districts C2-11 & C2-12, you have Bridgeport (21st) as the highest in power points out of either sub-district. A less deserving team in that district final could steal a spot from Elmwood-Murdock vs Yutan vs Freeman loser, Arcadia-Loup City vs South Loup loser, or BRLD vs Lutheran High NE vs Oakland-Craig loser. And this happens every year in multiple classes.
To me, fixing this issue ^^^ is a more pressing issue than making this a four day state tournament, or shrinking the number of classes, just to make sure all the games are played at the PBA or the Bob. Kids are wanting a fair shot to win a state championship, not boost tv ratings (I say this tongue in cheek) or please the average basketball fan that attends the state tournament. I don't know why schools or fans bring up the expense issue. If it gives me a fair chance to win a spot in the state tournament or a chance to play for a state championship, I'm willing to sacrifice a couple hundred dollars for gas. A kid's education will be more disrupted by getting slighted out of a fair chance at state tournament appearance than by staying out late for competing for a district championship. Just my opinion I guess.
