The ACC has to figure out where they are going as a league first. They never expected this to happen! They have always been the acquirer in the past and not the league raided. They felt impervious to it, especially after adding ND, which they thought was a real coup at the time, and then boosting the exit fee to $50 mil, they thought there was no way anyone would ever want, or could afford, to leave them!
So they have to look inward first and decide who they want to be and where they want to go. Do they appease the conference football powers? If so, Louisville is hardly a huge acquisition, though better at the moment than us. Still, not enough to keep an FSU or Clemson happy in the long run. So whether it's UConn or Louisville, do the FB powers run to another conference? Fifty mil is a lot of money...and those schools don't have the owner of UA waiting to help write the check, as MD does. Additioanlly, with the short-term boost to football comes the reality that by adding L'ville, they will definitely be negatively impacting the academics of the conference. This is not to be taken lightly either. The ACC flaunts their members academics whenever they can.
Market-wise, UConn seems a better fit. Louisville wouldn't do much in terms of bringing a large new market to the ACC. UConn would though, and it is the last piece of the NY market puzzle as well. They've got Syracuse, but Rutgers is gone now. Why leave the last piece on the table for the B1G?
If you are primarily looking at on-field performance and the status of the potential member's premier teams today, you can understand why the fans, bloggers, trolls and spammers are routing for L'ville today. However, it is only about today, as just 18-24 months ago, UConn was clearly the superior choice! Short-term success comes and goes and is not anything to base a long-term decision on! I think the presidents of the schools involved realize that too. So I differ from some on here who think that with the passage of time, UConn's chances go down. I feel they go up! When the flow of emotion is stemmed, logic takes over and UConn fits the ACC model and looks like a much better fit than Louisville!
