"According to an NCAA study of athletic department budgets in 2013, expenses exceeded revenue at all but 20 schools in the Football Bowl Subdivision. The average loss among the Power 5 conferences was $2.3 million. At all other FBS schools, it was $17.6 million.  The report also studied athletics budgets at Division II and Division III schools separately and found that revenues failed to exceed expenses at every school on those levels."

One could argue that the primary source of revenue that a Professor or Associate Professor brings to the University is the students in their class by way of tuition.  The student to faculty ratio at CU is around 17:1.  So if less than $9,000 per year per student goes to pay faculty they would be net zero while the NCAA's report accounts coaches salaries as the biggest contributor to the net loss for athletic departments.
