The cost of the Buyout is a factor - but at the same time - ticket sales are a factor.
If Oturu leaves and Pitino comes back, I don't see any way that attendance improves - and likely gets worse - unless they do a fire sale and slash ticket prices.
So the Buyout matters - but the loss of ticket revenue also matters. Don't forget that when Claeys was fired, one of the reasons given was the need to bring excitement to the program and improve attendance. At this point, you could make the same claims about the men's BB program.
