If they go for Chuck Jordan's "3 Class / 2 Division" proposal, here are the 68 teams that would be in 3A using this year's enrollment numbers. I had to take some "creative liberty" with the distribution of students from Lexington & White Knoll to new River Bluff HS.
The large number of teams should result in more compact regions, at the end of the regular season the class splits with each division having it's own 16 team playoff. (3 Classes during the regular season, 6 playoff brackets.)
I took a shot at dividing them into practical regions.
Link to the Map.
Low Country
The first constraint that became apparent is the odd number (13) of teams in the Low Country. Orangeburg-Wilkinson has to be included to even them out to create two 7 team regions that cross-bracket during region play.
Myrtle Beach/Pee-Dee
Horry County has 5 teams, add in the two Florence schools and then Hartsville to even out the region.
Midlands
There are 13 schools around Columbia, plus Sumter and the 3 Aiken Co. schools makes 17. Either Lancaster or Greenwood will have to be included to even out the group. After playing around with it both ways I included Greenwood in the group and divided it into three 6-team regions. Including Lancaster would have left 7 schools around Rock Hill and would have required Gaffney to be included with the Rock Hill teams, increasing required travel even more.
Upstate
I divided the 28 remaining schools in the Upstate into 4 regions of 6, 7, 7 and 8 to minimize required travel. Regions 2 & 3 would cross-bracket during region play.
Hey Slicker! Welcome back to the top classification!
