The San Francisco Giants’ surprising World Series victory in October led to mass celebration and ticker-tape parades in the City by the Bay. It also produced the usual theorizing about how a team could go from being down 0-3 in the National League Championship Series to sweeping the favored Detroit Tigers to win the Fall Classic. And the success of the Giants caused many to ask if their “secret formula” could be learned by teams in the corporate world. There were the usual clichés about the power of teamwork, players peaking at the right time, plain dumb luck and, of course, divine intervention. But none of these explanations really gets at how the Giants were able to overcome the longest of odds to become the World Series champs. One particularly common conversation has brought up the mythology that winning teams win by having players who have no egos. In fact, the noted business guru Jim Collins argues that the best leaders are “egoless,” that they are humble, unselfish and have little ambition. We’re here to tell you that is simply not true.
