@Techster Your Twitter guy posted today that the ACC expansion candidates that he posted are in reference to something happening sometime before the next Big10 and SEC media deals, not anything happening soon. ACC teams leaving and new ACC teams joining around the new media deals for those conferences is something I could believe. However, if it isn't going to happen for at least seven more years, there is zero reason to be vetting programs now. Any programs vetted now could be in a completely different situation in seven years. I still call BS on the first Twitter post you linked to. I think his post today was mainly a CYA, because nobody else is going to find information that backs up his original claim.
We'll see how it all plays out, but you should probably not get in your feelings about random tweets. There will be plenty of those tweets before the conference tectonic plates are finished moving. People were sure the B1G wouldn't take Oregon and Washington (tooting my own horn here, I said it would eventually happen...though I didn't expect it as soon as it did), and lo and behold things moved and Oregon and Washington were willing to take a partial share on the front end and the deal happened.
There's rumors that the ACC may let some of the disgruntled teams leave early for a significant sum as to not deal with the acrimony for the next decade while capitalizing before schools leave for free. Your opinion is that vetting is being done too early, but if ESPN/FOX (let's be honest, they're the ones ultimately pulling the strings) want to facilitate moving some chess pieces around while giving the ACC incentive to let certain teams go (for an enormous fee), then the ACC is doing the right thing by making sure they do their due diligence on teams possibly moving in to back fill the teams moving out. Guys like you and I have no clue what's going on behind the scenes with teams, conferences, and networks. Some people are better plugged in. You're more than welcome to be suspicious of anything you hear or read, but I'm inclined to just enjoy the drama because it doesn't affect me either way. I just hope GT isn't taking a step back by staying in the ACC. If GT does take a step back, that will be a situation our administration and some donors put us in, but my enjoyment of college sports will go on.
This is just entertainment for sports fans. I suggest you treat it that way.
