We should all think carefully and redefine our terms, and become more precise. The term "upset" doesn't always apply to the traditional little guy beating the traditional big guy. Mid-major doesn't mean lesser ability, and major doesn't mean superiority.
We need to look closely at teams, and look beyond their records to determine which teams can really play, and which teams cannot. We need to look at who you play, where you play, how you play and the circumstances of each game relative to the college basketball landscape.
We need to watch the games. The scores can tell us some important things, but far from everything.
