I think the State Championship arrangement is reasonable given the limitations. The winner of each Class has to travel a tough road. There are some very strong teams in the upstate sections . Winners of the tournament last year were Class A- Section 2. Class B-Section 5 and Class C- Section 8. The previous year Class A- Section 8 Class B - Section 1 and Class C Section 1 . It is just not practical to seed the tournament in a traditional sense. I think the 4 teams in each class in the semis are very strong teams. The ultimate champion is very deserving.
Also worth noting, the Sectional Finals are actually sometimes more exciting for the teams involved than the actual state championships. They are very well attended with a lot of enthusiasm from the various communities.
