death of a law student. Your answer is the correct one.
had to have been prepared late yesterday - or the Observer had a 48-hour leg up on the brackets. It has quotes from the team after the bracket was announced and it's by a staffer. Seems to me somebody could have done the same with something that occurred 24 hours earlier - if they cared.
They may not know, alas. (And I'm not kidding about some of them.)
