Honestly, with all of these arguments about culture fit between the Big East and B12, neither conference is a good culture fit for UConn. With the Big East you have proximity, and somewhat more like-minded people. But our institutions are not similar. UConn is a large, land grant university that does not fit in. UConn also does not fit in with the B12. The academics at UConn are far superior to those in the B12, and we are in two very different places culturally.
UConn fits in the ACC and the B1G. There are similar academic institutions and similar cultural fits. The ACC is dead, I don't want to end up there. The question is what gets UConn into the B1G. I think with the direction college sports are heading, staying in the Big East long term will leave us left in the dust. I think in 20 years schools like Villanova will randomly have their surges in the tournament, but will generally be afterthoughts on the national stage.
The debate then becomes, does the B12 give us a better chance of eventually getting into the B1G? Either option is honestly a gamble. We can't precisely predict how the college sports landscape will look 5, 10, 15 years from now. My only hope is that the administration does their due diligence to put us in the best situation to be among the "haves" at the end of the day. The last administration really screwed us on this, but I trust AD Dave moving forward.
Edit to add: It pains me, but I think the Big 12 gives us the best shot. The B1G will want to see football competence in a power conference.
