Regarding UL: Many ACC fans, myself included, would love to see this for hoops reasons. Regrettably I don't think this will happen because a) the BE is already courting UL and is considering adding UC (UL's longtime rival) as well, and b) UL's academic profile is substantially below-par compared to the ACC schools.
I'm in the camp that suggests that any school can be quite good given the proper support and guidance, and also recognize that UL is supplying a different education market than the ACC schools. If every school were a GT, than GT wouldn't be so special( ;D), so to speak. And if the ACC were trying to enhance their academic model, there's something to be said about the concept for helping a modest comprehensive urban school develop into a truly credible instituion. Alas, it will not happen unless...
The ACC (VERY QUICKLY) scans the field of prospective candidates and realizes that the pickings are indeed slim (understatement). Then, in a moment of clarity that has been rare as of late, they notice the value of the economic and cultural sides of the equation and understand that UL, and perhaps only UL, would give the ACC exactly everything it wants but the academics. With a gun to their heads, I suggest every president would take UL over ECU, Temple, Tulane, or any other non-BCS school. Their football is a credible addition, their basketball a huge asset keeping the ACC ahead of the BE in national perspective (possibly), more ACC/SEC rivalry, etc. And Cardinal fans would travel to Carolina for ACC events. Adding UL would balance the financial side such that everything else could be addressed in due course. Other candidates would/will leave at least a mild, sour taste for a while.
Perhaps the ACC, or select members of their leadership, either assumed they would get SU and BC or were edged into thinking that way as given little lee way from Miami. As such, UL was never truly considered in their original plans and the ACC has yet to regroup and properly consider them.
What should the ACC do? At this point, I honestly don't know, except to say act quickly, unanimously, and with depth of vision for the future.
