The alumni that really care will eventually die off. Chinese and Indian students for the most part don’t give a crap about football or basketball. Since they pay full freight, the universities woo them like they’re pretty girls. In Canada, talented hockey players go into the junior ranks where they are given room and board and a stipend, just like American universities, but they don’t have to pretend they’re students. The same process goes on in Europe also. Universities have sports teams also. College hockey in Canada and college soccer in Europe is played at such a low level nobody really cares except friends and family. The Dallas U-15 soccer team that beat the women’s national team would beat Oxford or Cambridge in soccer, probably by the same margin.
It will probably be after most of us are dead and gone, but I believe college sports will eventually be adopting the club model, Young men just aren’t that interested anymore, especially football. At best, it will become geographically regionalized, like college hockey.
In Florida for example, universities can tax a maximum of 10% out of state students. 90% must come from in-state by law. Other states have similar laws for their universities.
