Crap. I hate being objective. But...
Large UNC is very, very attractive. Flagship school of the largest state that isn't associated with the SEC or B1G. Legitimate national brand, Michael Jordan affiliation, large and loyal alumni base, large 3rd party fan base, great licensing revenue, fantastic academics, large athletic budget, geographically perfect for BOTH the SEC and B1G, and a lot more. If I were a conference commissioner I would probably (pains me to say this) have them as my #1 choice out of the ACC. You have to think longterm, and UNC is a place where the TV money would not go wasted. Whichever of the two conferences does NOT get UNC is going to suffer for it.
Virginia is being underrated in all this too. Another school with a high ceiling, good recruiting location (imagine UVA in the B1G or SEC recruiting the DMV), incredible academics, location, alumni, power-brokers, flagship of a major state, where newfound money could really launch them.
Both UNC and UVA have good sized stadiums (55k-65k iirc) that can easily be expanded further with the P2 TV riches.
Miami has a LOT going for it, and I expect us to land well. But we are still a small, private city school with a small AD, a lack of stadium security, and that is very different than the typical SEC or B1G school. We will be taken "in spite of" a few things.
