Still early, but here is what I see so far:
3A has 53 teams total. 32 will qualify for the playoffs. No certain order or quad, but the following are in (21): Sullivan North, Elizabethton, Gatlinburg Pitt, Cumberland Gap, CAK, Alcoa, Kingston, Polk, Sweetwater, Tyner, Smith Cty, York, Westmoreland, CPA, Camden, Cheat. Cty, Lewis Cty, Hickman, Milam, South Gibson, Manassas.
Borderline(14): Unicoi, Johnson Cty, Chucky Doak, Sequatchie, Grundy, Upperman, Goodpasture, Pearl Cohn, Harpeth, Waverly, Fairview, East Hickman, Westview, Jackson CM
The other 18 not listed will not qualify.
I don't know who will make each quad, I am just trying to guess the top 32.
