No, thats why Thursdays game was so huge. The TSSAA states that if two teams from the same region meet in the 3rd round, the higher seeded team will host regardless if its an even or odd year.
Now if Sevier County beats Central and Powell...then West will have to travel to Sevier Co because of it being an odd year and them being at the top of the bracket and in different regions.
I just think Powell is way better than Sevier Co and truthfully Sevier Co would be the 4th seed in Region 2 had they not been moved to Region 1 this season.
Could be wrong, but Id take Halls over them as well.
