IMO, if you play FCS football or don't have football at all, you are a Mid-Major. It's all about the funding and expenses of an athletic department. Even a Gonzaga, Villanova et al., are way below G5 level athletic departments. Doesn't matter how much they spend on men's hoops...they are still a lower athletic program. YMMV.

D-I is all about football. Though i wish they would classify the divisions by enrollment like its done for high schools all across the country.
