How big a deal is the Bucket win?

I know, IU's 27-24 win against Purdue is kind of a big deal. But how does it compare to IU basketball accomplishments?

I made it a point to go to Kirkwood last night to see what the scene was like. It was pretty lively, but not too crazy. So, how big of a deal was the win?

Is this bigger than a Conference title for the basketball team? A Big Ten tourney title? A Sweet 16 berth? What do you think is the relative level of accomplishment?
