I assume Porter is currently, along with his agent, looking at potential openings. I think, quietly, people in the industry know he's "open to work" (moving on from OU). DePaul was "real" last year in the regard that Moser would have left. What wasn't "real", IMO, was DePaul's interest in paying what it would have taken to get him.
As of today, and I don't see how it changes, he'll miss yet another tournament. Assuming that happens, it's best for both parties to move on. Moser is a competitor and I think he wants to prove his failures (at OU) are more to do with OU, and everything that the job entails, than himself. OU will prefer Moser accept another HC job because it'll lower the cost of their failure(s).
Some call it using a parachute.
Disclaimer: not going to list programs like West Georgia, Bellarmine, or other low majors that Moser likely wouldn't take. It's better to be an assistant than a head coach at some programs.
Potential openings (that could fit IMO):
Minnesota - big win vs Michigan but that still shouldn't change anything. The Ben Johnson era has been bad and should be ending soon. I kind of like the fit but I think Minny will want someone with recent tournament success/participation.
VCU - I expect Ryan Odom to move to a better job. Would be a sneaky good fit for Moser. It's a program that has a clear cut blueprint for success.
Charleston - Moser basically takes Charleston level talent anyway so I could see the fit...dependent upon openings and how they finish, I could see Chris Mack getting a better job after Year 1.
Northern Illinois - geographically, this would be a great fit. It's only 40 minutes from where PM was born/grew up. He could go home and build his own program from scratch essentially. The Huskies haven't been to the big dance since the mid-90s. Pay isn't great (may be able to offer their next coach $400-500K).
Buffalo - another MAC school that doesn't pay much.
Western Michigan - hey, another MAC school. Reportedly they pay a little more than Buffalo and/or Northern Illinois though.
Bradley - Brian Wardle should be getting "called up" after this season, finally. Bradley is located in Peoria, IL, which is about 2 hours from where PM is from, and they pay fairly ($800K+). This would be a really good fit.
Drake - I think Drake would want someone better but I can see a scenario where Ben McCollum moves on after one year and Moser being a candidate.
Appalachian State - probably time for Dustin Kerns to get a better job. We'll see how the season progresses, though
Arkansas State - After 2 years, Bryan Hodgson has done enough to warrant another job. Wouldn't be a bad gig for PM. Take what Hodgson has built and keep it
going.
George Mason - Tony Skinn might get a better job
Other potential openings (that could fit but aren't as ideal IMO):
Tulsa - Eric Konkol's time is up. I don't see Tulsa pining for an in-state coach who isn't getting things done, though. That would be a tough sell.
La Salle - Fran Dunphy is 76 years old...that lands him on retirement watch
Fordham - There's a chance they fire Keith Urgo. It's a really tough job in the A10 though and Moser should be able to find something better
South Florida - open now.....doesn't feel like a fit
Florida International - they're the type of school that could renew their commitment to basketball after firing their HC (Jeremy Ballard) but I doubt they'll pay Moser level money.
UNLV - I think they'll move on from Kevin Kruger but probably want someone better than PM.
Louisiana (Lafayette) - open now...but nah
Louisiana (Monroe) - open now...but nah
San Diego - they actually pay well but I can't see Moser coaching there.
San Francisco - Chris Gerlufsen is doing a moderately good job there, which may warrant someone else taking a chance on him, but it's not a likely landing spot for PM, IMO
Other potential openings (that won't likely hire Moser IMO):
Miami (FL) - open now
Virginia - open now
Syracuse
Indiana
Florida State
Virginia Tech
Kansas State - I think they keep Tang at least one more year but you never know
Arizona State
Villanova
Iowa
Rutgers
Texas
LSU
Washington State - David Riley could move on already but they wouldn't call Moser, right?
