Endicott or Babson or Bowdoin hockey are not funded by football.. Babson does not have it.. the schools that do have football are funded by football but not spectators, students. There are no scholarships, so a D3 school like Endicott gets guaranteed tuition and housing revenue (near 50k) multiplied by about 100.. near five million guaranteed each year from football. Let's say it costs at least half a million or more to operate it and we'll be generous.. say half the team are getting "academic" scholarships... That's over a million for one athletics program. If these things don't happen, and those students don't come to school, that's a lot of money they are expecting to get that disappears.
You can do the same thing with Babson's 25+ hockey players multiplied by estimated cost of attendance (over 70K). That's over a million per year coming to the school, guaranteed by the coach bringing in hockey players. If sports does not happen D3 will be hurt but not because of spectators
