I went and pulled up the rules and Frozen Tundra is correct. And by these rules, FC would be on the road in any Championship scenario.
Determining Home Team
First Round: The second-named team in the blind draw is host school unless the two teams agree to switch the site.
Semifinals: The team without a home game will host. Exception: The bye team will always be the visitor. If both teams were hosts or both were visitors, the second-named team in the quarter bracket will host. In 6A & 5A, in the four team sectionals, the second-named team will host.
Championships: Host team will be the team that has played the most away games. If both teams have played the same number of away games, the bottom bracket team shall host.
