The basketball floor has disappeared, suddenly. All that's visible on the TV screen right now, live from Assembly Hall, is a heaving sea of bodies, all of them dressed in red, the banners in the background red, too, the fans still left in the stands (Are there any?) a solid block of red, too.
A red-letter day. Yes, you could say that.
You could say that after Christian Watford's 3-pointer dropped down the well, and stabbed No. 1 Kentucky in heart. You could say a lot of other things, too: That this is Indiana's biggest victory since knocking No. 1 Duke out of the NCAA tournament nine years ago, and that the faithful can finally bury the Kelvin Sampson Error, and that, holy cow, the Hoosiers actually matter again.
What I can say, watching all that red, is this: I was there the night of the win over Duke -- in, ironically enough, Lexington. And the thing I remember clearest is how unreal it felt, how I turned to my then-colleague Jason Stein and said something as we followed Jared Jeffries and head coach Mike Davis' young son back to the postgame presser.
"What did we just see?" is what I said.
He couldn't tell me then. And, nine years later, I again don't have an answer to that question.
