I know most schools already had their schedules completed prior to Covid-19 demolishing society as we knew it. Everyone that I have heard from is operating as if the season will be played as normal without being concerned for gate revenue (as stated in OP, gate doesn't amount to much anyway, especially when all students/staff/family get in free). I am sure many coaches are planning for the possibility of not having a fall semester, or worse, any semester at all next year. Although, them planning for that does not really require much of anything other than accepting that they won't be playing sports/having students on campus. Basically taking a long vacation.
