Time is running out for this post season. All Knox County needs to do is let another system host the game. The parents could drive the players to that host site. Any liability issue that they are worried about is averted.
The best idea that I have heard so far is the elimination of four teams advancing to regionals. Three teams are plenty to advance and thus giving the number one seed a bye in first round of region. Oh, my bad, TSSAA wouldn't go for that. It would hurt their precious budget.
