Two year classification changes is more important in other sports. Why? Until/unless the district proposal comes into being, nobody truly knows exactly what football class they are in until the end of the season (unless they are one of the 32 biggest or smallest schools playing football). Everybody plays the same season. But, a classification change in other sports can change the regular season...Why...
Basketball is a good example. Four classes, with two weekends of state championships. Therefore, 1A and 2A Regionals start a week earlier than 3A and 4A Regionals. If your traditional small 3A team squeaks into being the biggest school in 2A one year, it probably already has game contracts for the last week of the 3A season - but now is going to be in the 2A Regional instead. Suddenly in June you discover that the last two conference games (Tuesday & Friday) have to be moved up. And your opponents for those games have to scramble their schedules as well.
Then on one year classifications, you go from the biggest in 2A back to one of the smallest in 3A the next year. You now have full contracts for a 2A season, leaving the last week of the season open before regionals...Again, you have to scramble your schedule to get a game the last week of the regular season.
CPS schools somewhat wild enrollment changes isn't helping the matter, or did the change a few years ago to hoops being four equal sized (25% per class) classes. The I-8 this last year is 5 3A schools for hoops, 5 2A schools. Next year Manteno, Coal City and Streator will be the 3 3A schools in the new conference...Don't be surprised to see schedules with those three playing each other the last week of the hoops season...
