I'm not sure about the game dates but I believe the seedings are
1. Lancaster
2. Northumberland
3. Rappahannock
4. Washington & Lee
5. Essex
6. Colonial Beach
7. Rappahannock County
Not %100 sure though
I guess power points from playing bigger schools. That's the only thing I could think of unless they just wanted them to have a home game since they traveled last year.
