The majority of schools are losing money on sports. You should have statistics on that...
Legit accounting stats I do not have nationally.
The ranking we commonly see is in USA Today, and three of the four schools in the OP were losing money on their list in FY2018. Bowling Green made $280K on $25 million in revenue.

This reference does NOT show that most programs lose money. It shows that >60% break even or make money. However, the NCAA reports that member institutions LOSE $8 billion annually on athletics.
So I believe your "majority of schools" statement to be true. However, on a list where most schools make money, most of the schools in the OP lose money. If legit GAAP accounting was involved, all four would probably lose money.
I make this argument because of the purpose behind many of these posts. "Look how bad they're doing" or "we haven't cut sports" comparisons are usually feel-good comments about yourself or an attempt to disguise your own performance. Not to mention, comparing yourself to athletics lightweights like Old Dominion and Florida International would be setting a low bar based on ANY data...
