When no one—and we mean no one (STFU if you claim you had the Bulldogs in the title game)—picks you to make the championship, and you not only nearly run the table, but do it in your own hometown, that's badass. Butler had an all-time great tourney run (two of 'em in fact), but it wasn't a true Cinderella—they were really that good. Taking Duke to the final seconds of the title game cements this squad on any list of the most badass teams in history.
