Every school is currently operating as if the fall sports are the ones "on deck".
It would be a significant change to flip the switch to have the (normal) spring sports be the ones "up to bat" first.
As a fall sport official, I already have a schedule of scrimmages and games for the upcoming season, with some holes still do fill. I also officiate a spring sport, and I am getting limited assignments right now in that sport during the non-high school summer season. If there is to be a fall scholastic season for the spring sports, they better unveil those plans very soon. Another factor to consider (especially for baseball) is that athletes have planned non-interscholastic tournaments for August on the premise that's not a school-season time, and then there's "fall ball" (though that's a slightly easier situation to shift out).
