1948 hangs over the head of any Cleveland Indians fans like a rain cloud. 29 out of thirty major league teams will fail to win a World Series this year, all but nine of those teams have won in this century, meaning that virtually their entire fan base knows the thrill of a title. Four other teams have won since 1990, and six more since 1980, so that covers well over half the teams in major league baseball.

Failure is a completely different animal when your team is zero for your lifetime, as is the case for the vast majority of Indians fans.
