Since three regions swept sectional/sub state, I believe that means that each of the following pairs of teams must be placed on opposite sides of the brackets...
Dobyns-Bennett & Greenville
Gallatin & Hendersonville
White Station & Hamilton
and by process of elimination
Bradley Central & Columbia
Is it wrong to hope that DB, Hendersonville, White Station, and Bradley Central all end up on the same side of the bracket?
