(ARA) – Any college basketball fan has seen it play out: One second left on the buzzer, the underdog shoots an incredible three-pointer and “game over!” You just witnessed an upset.

For many, these moments are cause for celebration. Whether reflected in your picks or not, an upset changes the tone of the tournament and makes for a more exciting game with a totally unpredictable outcome. What’s better is that every year, these shake-ups have a guaranteed place in the tournament.
