The data is scattered, but all of it says that most div1 football programs, especially those in the big conferences, turn a profit. It also shows college athletics as a whole tend to turn a profit (remember they also have basketball, which not only has massive revenue but it dirt cheap to put out there).
Sorry but athletes bring money to the schools.
Those schools only make money by furniture of there being in the same conferences as Texas, Michigan, Ohio State,Florida LSU, USC, Oregon, Georgia, Alabama, etc.
Abolish the conferences and the schools are now subsidized by the big schools Will be out of the football business.
