At this point, there are really only two certainties about the return of live sports: it'll revolve around testing capacity, and fans won't be a part of it.
Earlier this week, Los Angeles' stay-at-home order was extended indefinitley and the California State University system already announced its fall semester would be run virtually. Michigan governor Gretchen Whitmer already said they "won't be filling stadiums" this fall. Even in places like Arizona and Florida, where economies are beginning to reopen and politicians are explicitly lobbying for the leagues' business, fans currently aren't a part of the equation.
