If it wasn't easier to be lazy, I'd look to see if KU broke out revenue for women's VB since it's been pretty successful and has developed a good following. That's the only women's sport that comes to mind where KU stands out in the conference. But can the revenue gap between KU & K-State realistically be explained by women's VB alone?
No and don't bother because their women's athletics revenue numbers are cooked to hell. KU and K-State have had similar volleyball attendance, before this season anyway. Women's sports don't get NCAA tournament points for revenue like men's basketball does, so it's very difficult to have a wide variance in volleyball revenue, unless you're literally Nebraska.
