But back on topic of schools dropping football...
UOP is just a small private school; peers with Saint Mary's, Portland, Gonzaga**, Santa Clara, San Francisco, LMU, Pepperdine, and San Diego. Only one of whom as football (FCS San Diego).
The only schools their size who have FBS football are Tulsa and the service academies. The service academies get their funding from the Pentagon, so that's not an issue for them. And generally speaking, they kinda sucked for decades because they have weight/height restriction and the commitment to serve after graduation hurting them. (They're in a bit of a renaissance at the moment because of NIL has made college rosters be like "Every year free agency" on everyone's roster, so they have veteran clubs who execute instead of an all-new roster every year).
But the point is, in order to be successful at FBS football when you're THAT SMALL, you need something going for you. Tulsa has advantage Pacific doesn't: They're the "third school" in their state of 4 million and a top 60 market; California has like 25 DI schools.
Schools like Drake, Richmond, William & Mary, Furman, Holy Cross, VMI, Citadel, Villanova and the entire Ivy League who went down to FCS in the 1980s. Pacific probably should have followed suit THEN.
Saint Mary's, LMU, San Francisco... they dropped football in the 1950s. But Pacific stayed with Long Beach, Fullerton, Fresno St, San Jose State. Throw in the fact that UNLV joined the PCAA/Big West and they were elite in MBB in the mid/late 80s... (Being the late game on Big Monday after the Big East/Big Ten is why they changed their name to the Big West) and you can see why/how they held on for so long.
But once the WAC took Fresno St and UNLV, and Long Beach and Fullerton dropped from FBS; and Pacific was in a Big West with Arkansas St, Louisiana, Northern Illinois, and New Mexico St... the time had come. And that's no disrespect to those schools; it's just that Pacific stayed above the cut line for being able to pull off football way longer than all the other schools their size.
NOW, if you want to say "It would be awesome if college sports had some kind of smart system in place for economics, like pro leagues do, where there wasn't some kind of massive economic disparity between schools and someone like Pacific could have FBS football." I'm right there with you.
