I could see one of the Prep groups making finals. The 2A competition drops majorly after Hinton and Westwood. Sioux Center has been good in the past. They always finish above Lawton.
I don't know anything about the 4A groups except Hastings.
3A has some good schools. Webster City and Spirit Lake are always decent. To be honest, I dont know anything about South Sioux.
I don't really recognize any of the groups except Westwood Rebelaires... I'd put them in finals. Because their's is the only show on the list that i've seen this year XD
