This year specifically I think you could consider East Tennessee as East (without the Cleveland/Chattanooga) and be very close to being the strongest region over West, Middle, and the Chattanooga area.
The 4 State Winners from Greeneville, combined with the 3 state winners from Lakeway, throw in one state winner from DB, one state winner from Heritage, one state winner from Alcoa, and I think upper East Tennessee would be the strongest group across the state.
