Here's Torvik's blog about game score:

You can also see game by game win probability flow by clicking on a game score, like for example Penn State:

As you can see, the lowest the win probability ever got was at the start of the game. From there, the game was consistently 95+% in hand, though the lead was never completely safe until a Stojakovic 3 with 90 seconds left to make it a 13 point game. So, in essence, what we saw. The Illini got out to a solid early lead and sat on it, coasting to the end of the game, though it was never really in doubt. Other games they've secured a safe lead earlier (the Rutgers game was secured with 7:30 remaining and a 25 point lead), but they've largely played well in the vast majority of their games.
