titansfan05,
TSSAA stated in the preseason meeting that any two teams advancing from the same region would be placed in opposite brackets in Memphis. That way they could only meet again in the championship.
In your example, Farragut and Bearden would play their season match (done), then their district playoff match (this Friday?), then their region playoff match (following week). In the past one would go home here and the two region winners would play. This year they both advance to substate against the winner and runner-up from their pair region, and the winners of these two substate matches go to Memphis.
