Depends on what happens in the next two months, I think. In hindsight, a great win by a championship team regarded more fondly than a great win by a team that didn't end up going all the way.
Even so, tough to top some of the aspects of the Pitt game: the big deficit overcome, the clutch free throws, the late go-ahead bucket, the huge crowd (after two full seasons without a 30,000 game), the upset of a woulda-been #1 team (after two years of mostly falling flat against top opponents, save for Seton Hall in 2001).
After having been a top-five program for a half-decade now, we're used to big crowds and big wins. Maybe not as impressive as last night, but big event games are less of a rarity than they were in early 2003.
