Villanova is operating in another galaxy. Their athletic dept revenue last year was $40 million and they spend $9.5 million on mens basketball, $6 million on football. The $6 million they spend on FCS football is a rounding error for them. They play it as a lark.
But contrast that with ISUr. FCS football is a huge part of their budget.
ISU football expenses -- $4,062,137
ISU men's basketball expenses -- $2,452,961
ISU total ticket revenue for ALL sports -- $1,798,759
Let's say $1 million of that ticket revenue was for football, maybe $500k for media rights. That's still a $2.5 million budget deficit, which if spent on men's basketball would double their budget. They could pay Gregg Marshall money! But they're not, because they're bent on getting to Paris Texas! Yippee!
Actually they're lucky they didn't have to host a playoff game this year, because that's just more red ink (see above).
