I voted "Wildest Dreams"
Look, all the chicken-littles (mainly UConn Twitter folks) running around the pen screaming "We need to stay in the BE, it will rip the heart and soul of the program out and we'll never recover!!!!" are holding on to some bizarre nostalgia for the original Big East. Which is comical, because many of these folks were not even born when the original Big East was in its glory.
The Big East originally made great sense when we first joined because UConn--although yes, we were a state university joining a Private / Catholic athletic conference even back then-- UConn was nowhere near its current level of academic and athletic quality. The reality was it was a dumpy run-down safety school with I-AA Yankee Conference football. I know this well...I went there from 1988-1993. I have since worked there as a professor from 1998-present. I have seen UConn's stature rise both academically and athletically. Not to mention there was no internet, broadcast media was local/regional/paper-based, etc.
Although the move from the AAC back to the "new" Big East made great sense, it really could only be a transition step given the current academic/athletic department state of UConn and where we want to progress to in the future. Not to mention that while I am as nostalgic as the next middle-aged rabid UConn athletics fan (likely even more!) for staying in the Big East, we can't just stay here. We've outgrown the conference.
Yes it stinks, but for so many reasons, we need to move on. And we will thrive. I'm at peace with a move to the B12, and am very confident it will be a very positive thing.
