Football programs can cover the spending for a lot of other womens and mens sports for any university.  I did crew/rowing at the U of Wisconsin, which got MOST of it's funding from football program revenues once the football program turned things around with the hiring of Barry Alvarez.

I took a 3rd place finish at the Head of the Charles back in 1991 ... couldn't have happened without not only the funding from football program, but their leftover jocks, socks, t-shirts, and shorts.  Rowing back then had no scholarships.  Rowing made me tough, tenacious, strategic in outlook and knocked some of the punk @$$ out of myself with straight up discipline and training.  Since I was also busy partying my rump off in college, it was a shining ray of good health that helped keep my 'dad bod' in somewhat good health into my 40s now.

Women's sports in particular have everything to do with football revenues.  Without those inflows of revenue, ain't gonna happen ...
