First of all there is no Nationals for squirts. Nationals start at Peewee division. Second, any team can register as a tier II team and be eligible for Nationals. Thats a AA, A, B, or whatever you want to call them. Tier II is just Tier II. All other teams are considered House/Rec. So for each state now all Tier II teams must playoff to determine a state champion which then goes to Nationals.
