I haven't been able to see what will happen in Region A this year as it doesn't look like it is posted anywhere. It looks like there are 10 boys teams competing and 6 girls teams competing. With at least 3 different districts represented. I don't know how seeding will work for that tournament
Region B has these standings posted on their
Weebly page. Looks like only 8 Boys Teams and 3 Girls Teams competing in that Region. Again there are 5 different districts represented here so I don't know how the seeding for the region will shape out.
Region C has two districts. The Pioneer (Boys 5 teams, Girls 3 Teams) and the Mountain Empire (Boys 4 teams, Girls 5 teams). The Regular Season Champion from each district gets an automatic bid to the Region and the district tournament champion or runner up if it is the same champion get into the region. 4 total teams for boys and girls.
Region D has 2 districts but only 4 teams - Honaker, Patrick Henry Glade Spring, Rural Retreat and Grundy (listed on multiple teams schedules but I haven't seen a posted score for them yet so I don't know for sure if they have a squad) competing on the boys side and only Honaker competing on the girls side. Normally this is decided when Honaker and PHGS play each other in the regular season since they are in different districts but I'm assuming they will need to play a region tournament this year having 3 teams on the boys side.
