Actually, you are wrong. It was very personal for the schools that left. Because each ACC raid of the Big East was predicated on the fact that by taking 2 or 3 teams, the ACC could put the Big East out of business, essentially destroying the league and the athletic programs within it. Every time the ACC would grab a BCU or Syracuse, they would go running back to ESPN and ask, with their tail wagging, "will you give us credit for the Northeast now?" The point of those raids was to make UConn a mid-major. Do you really think that Syracuse and Pitt are valuable athletic programs in their own right?
If the 9 football (with TCU) and 8 hoops schools had stuck together, the league would have already signed a contract worth at least what the ACC is making. That Big East was better on the field, on the court and in the ratings than the ACC.
Or, the ACC could have gone to the Big East and said "we have this crappy long-term TV deal, why don't we merge into your league so we can get out of that deal and all make a lot of money?" But they didn't do that, probably because Swofford may not have survived that process. They convinced Pitt and Syracuse to stab everyone else in the back, which caused the Big East to ultimately unravel but didn't really help the ACC's with their below-market, long-term TV deal. The current solution is the worst of all worlds. The Big East is gone, never having gotten its big TV deal that it was due. The left-behinds are relegated to permanent mid-major status, and the ACC STILL has a crappy TV deal, making it incredibly vulnerable.
Just because their are worse outcomes does not mean UConn going to this configuration of the ACC is a good one. It is just UConn trying to make the best of a bad situation, which will continue to be bad into the future.
