Your comment is about football but your links discuss subsidies on entire athletic programs. It is well known that more popular sports offset expenses for less popular ones (especially those satisfying title IX) and many times the schools have to subsidize even further. I think you are confusing the expense/revenue ratio of college football with college athletic programs as a whole.
