It's a really good question. If you're an FBS school, football runs your athletic department and the reality is that MAC schools simply can't compete with the FCS $chool$. But, due to the current college football landscape, they have to keep trying. Take Miami and BG. Miami is towards the top of the MAC in athletic department expenditures while BG is towards the bottom. However, Miami is also towards the top of the MAC in borrowing from the general fund to cover athletics overruns while BG is toward the bottom. And according to Bergeron, Miami's travel went up $200k in the NCHC's first year. That's not sustainable with all that football cashola being shoveled out the door when neither school sniffs a New Year's Day bowl payday (you can count on two fingers the number of times a MAC team played on New Year's Day). Subsequently, the rest of the MAC schools fall somewhere in the middle but none of them escape the football wars. Heck, Akron built a new football stadium which they don't have the money to pay for -- they ain't startin' hockey...
For MAC schools, facilities aren't necessarily the issue...it's football and Title IX. So yeah, ain't happenin'. And Miami and Western aren't "hockey schools," they're FBS football schools. Like BG, Akron, Buffalo, etc. Follow the money.
