I'd say UNC, but I think they may have been a little distracted by the investigation into their corrupt "school." I'm not saying #5 didn't cause a great deal of butthurt, but the NCAA announcement shortly after the title may have shifted their focus. KY had its dream season ended, but not by Duke. By the team that Duke beat twice this year. So, they may be more butthurt at Wisky. Now, Wisconsin and it's temper-tantrum throwing coach are probably the most upset. I doubt we see Wisky in another F4 anytime soon. This was their last chance for a while. Other schools that might be upset are KU (putting some distance between two schools that were tied at 3 NCs 6 years ago), IU (knocking them down the list of all-time greats), and MD (just b/c it's MD).
I'm going with Wisconsin.
