it's actually pretty smart because that game won't count against the RPI. It's better than playing Mississippi Valley St. and having your RPI go down. RPI says the game never happened.
It also can give the second string players a chance to break into the rotation since the game will get out of hand early.
It's Baylor's turn at a "bye" week, so they probably want to keep their players in a similar routine since games in the big 12 is usually tuesday or wednesday then saturday. Without the game tonight, they'd have a full week in between games.
