Obviously we need some sort of label to refer to this past Sunday. Black Sunday or Bloody Sunday sounds too easy. I think it requires it's own special moniker so we can refer to it in passing without talking about it in detail and traumatizing ourselves all over again.
Update: Given the tragic nature of what happened to Jason Ray on the same weekend it seems inappropriate to refer to it any terms which denote actual tragedy since it is still just a game. So in light of this I will refer to the 2007 East Regional Final as "The Georgetown Game."
