Using EPJr's proposed class breakdown (basically dividing # of competing schools (315) by 5 Classes = ~63 schools per Class) would work out this way using the ADM figures from March '18. This is just for kicks. If they did go to 5 Classes I'm sure things would look differently. For kicks tell me the 8 teams you think would make it from your Region.
