There are a few things to keep in mind when looking at these expenses:
1. Any cost of renting arenas is included as an expense, so a school that rents an arena will normally have a lot more expense than a school that always plays in a facility they own.
2. Cost of scholarships is much higher for most private schools as opposed to public schools. For example, Colgate - a D1 weakling who doesn't emphasize basketball - ranks 140th out of 342 schools with expenditures of $1.427M. However Colgate's tuition, room, and board runs at $58K per year, making the cost of 13 scholarships $750K - far more than most schools.
3. Unusual expenses - such as bonuses for coaches meeting certain goals such as winning their league, winning a certain number of games, advancing in the tournament, etc - are included and may skew a given year. Same with buy-outs for coaches who are fired.
4. Ivy's do not count any financial aid to athletes, since those payments are hypothetically the same for all students. Army also does not list many expenses.
5. Teams that advance deep into the postseason will have more travel expenses (but also more revenue).
6. Many expenses are not defined in the government report from where Basketball State got its info. For one big example, there are many expenses in an athletic department that can either be allocated to a given team or charged off as general expenses, such as maintenance expenses of a team's arena, practice facility, or training facility. Also certain personnel costs. UConn, for example, has about $21 Million of athletic expense that is not allocated to a given sport.
