Gibson County couldn’t win the district because it would be three way tie if Peabody lost.
Gibson County beat Peabody
Peabody beat TCA
TCA beat Gibson
this makes a three way tie for 1st if Peabody looses and Gibson wins so Peabody has Tie Breaker because if their record so they have clinched the title no mater win or loss. The best GC can do is 4th or 3rd. That is because of the UC loss to McKenzie.
