As a High School teacher and a Middle School FB Coach this is how I see it in Iowa. There will be less than zero leadership from the state on fall sports. I can see schools trying to play HS football, but getting hammered harder than we are in BB/SB due to contact. No games at the Middle School level, but still having practices and scrimmages so kids still learn the skills.
Most schools will start in person, and most won't have mask required due to the feedback they get from parents who say they won't send kids if mask are required (of course there are also parents who say if masks aren't required they won't send there kids). Schools are in a tough situation with little leadership from the top. You're looking at $8,000/kid in state funding, so if 30% say they aren't sending their kids, schools will have a tough row to hoe. There will be a lack of subs this fall and we will see a high percentage of teachers leave the profession.
That is just my opinion, but I think it'll be ugly.
