Syracuse and UConn where initially targeted for expansion by the ACC. However, BC played a role in getting Pitt selected over UConn. This is pretty well documented. Even a genius should be able to Google it. Efforts by BC (hardly the ACC power broker) were aided by another factor. The ACC was pitted in a battle for survival against the Big 12, which had just lost, or was in the process of losing, 1/3 of their conference. Some in the ACC believed that Pitt could have been taken by the Big 12, especially following the exit of Syracuse and UConn. Additionally, there was a prevailing consensus that UConn was an unlikely target for the Big 12 and Big Ten to kick off their Eastern expansion.
Following Maryland's announcement to exit the conference, the ACC was once again in survival mode. While UConn had support from Tobacco Road and academic-centric institutions, the football-centric schools led by FSU and Clemson, wanted to counter-balance Tobacco Road's influence (shades of the BE here) and the incursion of Northern schools, and pushed for inclusion of Louisville. Remember, the GOR was still several month's away and the conference needed football credibility (real or perceived) more than they needed top academic schools. Many in the conference felt they needed to appease FSU and Clemson, who had both publicly stated that they would review all options when it came to CR. Their departure would have been, and still would be, a devastating blow to the ACC. The fact that Louisville was the other "finalist" for Big 12 expansion (losing out to West Virginia) helped add momentum to their selection.
UConn getting passed over had more to do with timing, geography, politics, ignorance, population, NCAA bias, short-sighted defense of turf, and to a certain degree, football. It had nothing to do with athletic, academic and research excellence. UConn will continue to compete for national championships, grow our fan base, rise in academic rankings, dominate NYC, and forge ahead with its multibillion dollar research endeavors. The B1G and ACC can either sit back and watch it unfold or they can decide to be a part of it.
