I agree with what your saying, but I don't know that it would happen the way you think it would. The big "to do" with the NSAA right now in football is to minimize the huge number difference between the top of B and the bottom of B. For next cycle Aurora will be C, I think Holdrege will be C. That was the number 1 reason behind setting enrollment numbers as cut lines, to shrink the enrollment gap between the biggest B school and the smallest B school.
I'd like to think if they merged both C1 and C2 into one class (C) it would mean the top third of current C1 would go up to B, but I'd bet it wouldn't happen because then you get that big numbers difference between top of B and bottom of B. I'd be hard pressed to believe they would build that gap after they just shrunk it. That's all I'm saying.
Regardless, the thought of Aurora playing Shelby-Rising City is insane, and those two would end up in the same district. Holdrege would be in a district with St Pat's (whose number was something like 35 for this coming cycle). You really think that is good for high school football?
Your exactly right, that is insane. I don't think myself nor anyone else that is advocating for a four class setup thinks that would be a good idea.
Class B is an issue with the school size gap. As someone else mentioned that many of the C1 schools are more similar to B than C2. I'd agree with that, especially at the top. Many of the bottom and middle of C1 schools however fit in with the top C2 schools. The main thing that is challenging is closing the gap in B. I've mentioned this before that the member schools and NSAA are approaching it in the wrong way. Instead of shrinking the bottom of B off shrink the top of the class off. After you get past Elkhorn, Elkhorn South, Gretna, South Sioux, Columbus, Hastings, Scottsbluff, and Ralston the enrollments drop fast with many being in that 250-400 range. Those top teams mentioned in B could compete in class A. Most do in other sports already. Facility wise they are similar and most were A at some point in the last 10 years. The thing that pushed them out more than declining enrollment (very minor in most cases if at all) is the addition of Papio South, Lincoln SW, and Lincoln Northstar and growth of Pius. Because of this I feel the solution is to have A and B both go to 36 for all major sports. This would put the largest B at Lexington (630) and then Blair (554). Besides Lexington the enrollment gap is majorly closed compared to current. Next the top 12 in C1 would go up to B. Enrollment size, facility wise, etc they are similar to the remaining class B schools. Lastly combine the remaining C2 schools and we have a new class C. Combine D1 and D2 to make one 8 man Class.
A four class system (5 for football for 6 man) would encourage more schools to coop. Right now schools are so afraid of going up a classification. I can't blame them as most times it consists of one school that badly needs it and another that doesn't. The school doesn't need it would rather stay where they are as opposed to add another school and go up a class.
Also, look at the enrollment gaps of other states, especially in volleyball and basketball. Iowa for example has a four class setup. Not sure of the exact cutoff but somewhere around 150 and down is the smallest class. It's not crazy to have a four class system, some just don't like change because that's the way we've always done it. With the number of schools we have in our state a 6 class system is getting absurd. The quality of postseason play is getting worse in all sports.
Lastly, I would do like many states do and have overlapping 8 and 11 man cutoffs.
