The way I understand, four districts make up a quadrant. The four district champions will be the top four seeds in the quadrant. Each champion will host a game. Then the second place teams are seeded next, then third (if any) then wildcards.
I am sure that White station will be hosting a game, along with Germantown, Brighton, and the Arlington, Millington winner.
Alot of the seeds hinge on the Arlington-Millington winner. If Arlington wins they are the top seed followed by G' town, WS, and then Brighton. If Millington wins, then Germantown is the top seed, followed by WS, then Brighton, then Millington.
