This might be an exception proves the rule argument, but Fairleigh Dickinson got to the pinnacle for an NEC/lower D-I school by recording the 16 over 1 upset a couple years ago. That resulted in the best-case scenario for smaller schools in which the increased interest over a weekend or two dramatically raises applications in subsequent years. I can't find FDU enrollment numbers for '24-25, but Saint Peter's, which some people out this way thought might have to close during the pandemic, experienced its biggest enrollment in 25 years for the 2023-24 school year...which, of course, started 18 months after the miracle run to the Elite Eight.
Go forth and change the world.

Now, of course, this is the sporting version of someone hitting the lottery and solving all their pre-existing problems. It's not exactly a blueprint for everyone else. Still, it's a bummer to see a school get its moment in the sun immediately before it begins planning a move to D-III.
