Only if they want to retain Rueck and have a winning program. It's supply and demand, the foundation of our nation's capitalistic economy. If they started capping the salaries of WCBB coaches that would solve the problem (??) of men coaches coming over to take the jobs of potential woman WCBB coaches.
I'm not saying there should be a cap, but you bring up economics. If an athletic department is tens of millions of dollars in debt, why are they outbidding themselves to raise the salary so much of a coach whose program loses money? There are athletics departments like Stanford that make enough money to rationalize overpaying for a lot of sports coaches in the non revenues. But a lot of schools don't have that money.
In fact, many of these schools are using money from students or taxpayers to run their athletic department. I think those universities should have some responsibility to be good stewards of that money.
At a time of tight budgets throughout higher education, even the nation's few financially self-sufficient major-college athletics departments are continuing to receive subsidies in the form of student fees, school or state support, a USA TODAY Sports analysis finds. https://www.usatoday.com/story/sports/college/2013/05/07/ncaa-finances-subsidies/2142443/
