Your point (as I tried to understand) was that a trained official should be able to easily distinguish a immediate kick into the air and an immediate kick into the ground. If the NCAA recognized with their higher trained officials it's not easy or discernible then how would our much larger population of high school officials (who have a much broader range of experience) be more qualified to do it?
