Like another poster wrote, it took 7 years for Syracuse to get into the ACC from the last realignment round, I think we are in a similar spot. In the medium term we will be alright.
Also, I feel SEC going to 16 is inevitable. Their East, West alignment does not quite balance. I believe they will look to add two eastern schools (FSU, Clemson) in the very near future.
Furthermore, if UConn and Rutgers are just hanging there with the departure of WVU, UL and UC, I can certainly see the ACC sending a lifeboat.
