You can't end the low revenue sports, though, because of Title IX. If you have about 100 scholarships for male athletes, you better have some form of reasonably equivalent opportunity for female athletes or you'll get your whole athletic department will be shut down. If you pay the men, you'll have to pay the women. The number of athletic departments that could reasonably pay anything more than a token sum to athletes without going deep into the red is probably less than 20. Iowa would be on the very fringe of that group. Iowa State would be toast.
