To be clear--I don't think he opted for Louisville. Commissioners don't have as much power as we think, sometimes. I think he assumed they would add UConn when Maryland left, just as he thought they were going to take Syracuse and UConn rather than Pitt. It's just that some of his member schools had other thoughts and concerns.
As for the rumors as a whole--they're obviously not real rumors. But the ACC intimated that they were taking Louisville over UConn and, to a lesser extent, Cincy, because the latter two schools had nowhere else to go, while the former had the B12. Anything in a major publication that suggests--even erroneously--that we could go anywhere else but the ACC has to scare them. They know they can be raided again, and despite what they'd have you believe, they know that once you get past UConn and Cincy, there are no other desirable east coast schools (sorry USF).
If we're taken off the table by someone and the ACC loses more than one school, they have to start looking at Temple, USF, and UCF--or take a school like UMass* because their academics aren't horrendous, or a school like Memphis because, despite their academics at least they have a live basketball program. Do they take SMU because there are decent academics there despite a program that got the death penalty? I mean, think about it, it's gruel on the east coast after UConn, and to a lesser extent, Cincy...
*I know they don't take UMass--but for all their talk about academics, after UConn, what is there? Although, I guess, once you take Louisville, academics go out the window...
