There's an argument to be made that, particularly since they're no longer tax-deductible, that these aren't really donations at all but something closer to seat licenses. Many (most?) might not be "donating" if it weren't for their seats.
I think the smart play for the athletic department would be to offer people their Cyclone Club donations back if they choose but campaign hard for people to leave them alone. I suspect most would do so anyway, and they would generate a lot of goodwill.
but your donation applies to basketball too.
