JMU is not like other schools. Their students pay almost $2600 in athletic fees a year with 73% of their budget being covered by these fees. For contrast, Akron doesn't break out an athletic fee, it just charges a $2400/year Akron fee. A small portion of that goes to athletics, while the rest goes to admin, facilities, etc.
I also saw that JMU is including a corporate sponsorship of the conference on top of the registration fee. How many schools can offer that? The corporate sponsors have not been released yet.
