Looking at all the current ACC teams, Pitt, and our future schedules it appears to me the best year for us to join in 2013. Then everyone would be able to play 9 ACC games without having to move too much around. I think next year would be a bit of a headache for teams. So I am going to guess we start in 2013 for FB and 2012-13 for BBall.
Looking at the potential BE replacements it appears that Boise St, Air Force, SMU, HOU, and UCF could all easily join the BE in 2012 without issue. However how does Navy get out of 12 non BE games that they have scheduled for the next 10 years? How early can they come, or will they? I doubt they come in 2012 but that is ok for the BE since Pitt and SU will still be there.
So I am going to guess that Boise St, Air Force, SMU, and HOU are added to the BE for next year to create a champ game. Then in 2013 they add UCF and Navy to replace SU and Pitt. As long as Navy can get there in 2013 we are gone.
