If you think about it mathematically, you can assign a non-negative real number instead of a discrete 0 or 1. The result is that you can specify a level of confidence you have about a predicted win or loss. A win percentage more (less) than 0.50 means you're inclined to predict the game as a Nole win (loss) - just not every time. A win percentage of 1 (0) means FSU wins this game 100 (0) times out of 100.
