There are two things that I like to do in the week leading up to a big game: watch at least one classic game against the same opponent on dvd during the week, and read an old mgoblog post recapping a game against the opponent.
This week, both are the 05 game of course. In case you haven't read the New Math in a while (or ever!), here's Brian's summary of the game: The New Math
Watching the 4th quarter of that game still gives me chills... and so does that post. What a classic ending.
