Region 8 (9)
All the Memphis schools. There will be 9 teams but theres not really anything else you could do with them.
I did not spend a lot of time on this so if there is anything I missed let me know. Only potential problems I see is the West having more teams than the East and region one having only 4 teams. The 8 teams in region 6 could easily be fixed but all of those teams are decently close together. There are several swaps you can do between regions 4-5-6-7 to probably make this better.
