Interesting to see that it appears UNL has gone the Iowa route and divisions are now based on school enrollment. I'm curious to see if this is an isolated change or if the entire state has adopted their neighbor's practice of divisions.
There are Nebraska comps that have long used school enrollment/NSAA divisions like Iowa uses enrollment/IHSAA. The Grand Island comps come to mind as using that AA/A/B/C/D system. I know I've seen those pesky letters somewhere when adding previous schedules.
