Tough job re-seeding the 4A bracket when 5 of the teams are undefeated. How should they be seeded?

Bowie (Undefeated)
Catonsville (Undefeated)
Sherwood (Undefeated)
Severna Park (Undefeated)
Churchill (Undefeated)
Northwest
Northwestern
Arundel

My take is:
1) Severna Park
2) Churchill
3) Arundel
4) Catonsville
5) Sherwood
6) Bowie
7) Northwest
8) Northwestern
