I don't see them dropping below a 2 even if they get blown out by South Carolina. If they lose an AAC game, then they drop.
They'll need multiple teams to come on strong (ex. Mississippi State/UCLA/Maryland) to sneak ahead, and I don't see all of those squads making a strong enough surge to supplant UCONN. We'll see though.
If UConn loses @ South Carolina, their signature wins this season are at DePaul and vs. Tennessee at home. That is an awfully weak resume for a two seed.
Whoever in the PAC-12 is #2 behind Oregon will presumably have at least three more wins against UCLA/Stanford/Oregon State/Arizona/Arizona State.
If
Stanford, they already have wins vs. MSU, Gonzaga, Tennessee, and @ Oregon State.
And
UCLA will have @ Indiana, vs Arizona, vs and @ ASU, and potentially at least one of the Oregon/Oregon State/Stanford trio.
Same math for
Oregon State, with wins vs. DePaul, vs. Missouri State, @ ASU, and the same possibility of wins vs. the other top PAC-12 teams.
MSU could have wins at Tennessee, vs. TA&M, @ Kentucky, and vs. Arkansas.
Maryland, given the way the committee seeded them, are already on their way to a two seed and they can still pick up wins @ Indiana, vs. Iowa on top of vs. Indiana, vs. Northwestern and vs. and @ Michigan.
NC State has wins vs. Maryland, Texas, FSU, and will have two chances for signature wins vs. Louisville (regular season and tournament). Split those - especially if they won the ACC Tournament- and NC State would be a very strong probable 2 seed.
