Nothing will change this year I don't believe. It'll be in 2018. (I'm using the link above.)
I'd love to see Class A be 24 teams. Pretty much every school under 1,000 enrollment. That would put Fremont, Norfolk, Pius X and North Platte in Class B. In all sports I think it would benefit them.
Have B1 and B2. Take those top four and have B1 be 32. (So the bottom four of Class B would be the top of B2. That would be Aurora, Platteview, Omaha Gross and Holdrege.)
B2 can be 32 teams. Take those top four and add them to the top 28 in C1. (The remaining C1 schools would go down to the new C1. Bishop Neumann, Pierce, Conestoga, Ord, David City, North Bend Central, Chase County, Louisville, Mitchell, Aquinas, GICC, Lincoln Christian, Madison, Southern/Lewiston, Norfolk Catholic.)
Have a new C1 would add the above 15 teams and take the top 33 from the current C2 to make a 48 team class. (Which would put the lowest school at 100 kids.)
The new C2 would could be a 9 man class that adds the remaining 11 schools to the top of the current D1 and that makes a 48 team class. (Which puts the lowest enrollment at 70 kids.
Then you have Class D1 with enrollments under 70 to 50 that play 8 man football. (Would be like a 50 team class.)
The new Class D2 would have all enrollments under 50 play 6 man football. Which would be like 40 teams have the NSAA sanction it.
