I didn't work this game, but was in attendance when two HS teams played a playoff game at a unmodified BCS stadium, i.e., 18'-6" goals. Team X missed a field goal to win the game by less than two feet, then Team Y missed a field goal to win the game in the first extra period by less than 2 feet. The winner eventually won via a TD. Both HCs were probably kicking themselves for agreeing to play at a site with 18'-6" goals. But their ADs and Superintendents were probably OK with the 30,000 attendance (less the UIL's take).
