I managaed to pick 26 out of 32 on the first round. Yeah, Big Ten and Big Twelve did quite well so far. I didn't see it, but the scoreboard kept me felling like Illinois would win, but they forgot to play the last 2 minutes.
(EDIT: I miscounted - I picked 26 of 32), and 7 of 8 in the second round yesterday. So far except for Vanderbilt, my Sweet sixteen picks are right on).
