The IHSA really needs to allow teams to scrimmage someone else the week before the season starts. It would be more beneficial for the vast majority of schools to go against someone else when working on 2 Minute drill, Special Teams, 3rd Down etc then against your backups or Sophomore team.
The scrimmage shouldn't be scored and involve refs. Teams could set up the format any way they wanted. For example, maybe you want to rotate every ten plays, or you want to move the ball until you are stopped. You could take turns working on two minute drill or goal line situations. While you can do those things against yourself, most schools do not fully two platoon at this point and struggle to get a look in practice against backups.
