There are significant cultural differences between WVU and the ACC that will never ever ever go away, specifically between North Carolina and West Virginia. The ACC has turned down WVU about a dozen times over the last 50 years, maybe more. They wouldn't take WVU even if it led to the death of the conference.
I know I've been tough on UConn but a lot of it is frustration when you guys badmouth Louisville incessantly. To be honest, I'd like to see UConn round out the ACC if Notre Dame ever became a full member.
The key is UConn's membership in the AAU. (UConn's metrics are strong enough now for inclusion.) If and when that happens, I think the B1G will be interested and then the ACC will also be interested. This will be because we'll be the only eastern presence left. At that point, I would much prefer the B1G for myriad reasons.
