What they should have done weeks ago is shut a full year of sports down completely. Workouts, testing, meals, medical staff, medical services, administrative staff, etc all cost money, and to be brutally honest, sports are something that you can mothball and put in storage at little cost if you do it right. Coaches making a over an arbitrary amount of say, $150K can be cut down to that $150K level temporarily with a stipulation that a percentage of it gets prorated back spread out in future years once sports resume (where are they going to go? No one's quitting). You're not really saving a lot of money cutting salaries of people making $50-60K a year, KF, BF, PP, Barta...those are the people where you'd get back some meaningful cash. Facilities have minimum maintenance, but that can be absorbed and isn't huge.
I know it wouldn't be a popular decision, and there will be current players and incoming high schoolers who get hurt in certain situations, but the world is a hard place. It happens.
And it's also inevitable anyway. People who think there will be successful reintroductions of American sports teams before a vaccine is widely distributed are loony toons.
