There's really not a good solution. Non-revenue sports are always going to be facing cuts. If you limited to having similar sport offerings, then it's probably only basketball, baseball/softball, and football/something that are offered, and even baseball is limited to a handful of universities.

If you limit scholarships like the current system, because football has so many scholarships, there needs to be 4-5 women's sports to be balanced. If you add some rules to force offering a men's team for each women's team, then it's a huge benefit for the men even if there aren't scholarships available.
