I am a life-long UConn fan (born and raised in CT). The Navy brought me to the beautiful PNW over 40 years ago (1985) where I have lived ever since. Both of my children are WSU graduates and I count many other Cougar and Beavers fans among my circle of friends.
A part of me wants to get excited about this potential move but in the end I don't believe this makes much sense. I followed the old PAC-12 very closely (my wife and her family are all UW grads) and continue to read every bit of news on the new PAC-12.
Some of the posters on this thread have talked about the league potentially buying out UConn's future schedule commitments, but what you may not know, is that while WSU and OSU received a significant payout when the league collapsed, they are still in litigation with the Mountain West over poaching several teams to the tune of $55M. I can't see the league using any monies for buying out UConn's commitments until that lawsuit is settled.
From a competitive standpoint, I think the football schedule would definitely be an upgrade over the current slate. BSU, WSU, USU and most recently SDSU (not so much last year) have had competitive teams, having qualified for bowl games. However the travel logistics and costs outweigh this competitive upgrade.
From a basketball perspective, especially for the men, replacing teams like UTSA, ETAM, Bryant and UNH would be a definite upgrade. I realize that UConn wouldn't replace all those quad 3/4 teams with PAC-12 schools but replacing 2 of those would be a definite schedule upgrade. Gonzaga, Utah St., SDSU and CSU are quality programs.
As for the women, not so much, although OSU was a competitive team before the breakup and WSU was a program on the rise. And while BSU, SDSU and CSU each won 25+ games last year, I don't see Geno replacing his traditional opponents, dropping any of those games if at all avoidable.
In the end, a reluctant thumbs down from this PNW based UConn fan (who is also rooting for a successful new PAC-12).
