As a kid that was born in Kentucky and still has family there, I'm a little biased but I love the fact that Louisville is now part of the ACC.  It will certainly add another basketball program of significance and a decent football program (meaning they should fit right in). 

Here's more from ESPN on the addition of Louisville to the ACC.

The ACC's presidents and chancellors voted to add the Cardinals Wednesday morning to replace Maryland, which will leave for the Big Ten in 2014.

Louisville is expected to join the ACC in the same season, sources said. Big East rules require a $10 million exit fee and 27 months notice, but the Cardinals -- like several schools before them -- should be able to negotiate a higher buyout to leave before the 27-month period.

Here's more from ESPN including a video of Andy Katz talking about expansion.
