Ex-Cubs Factor hypothesis

The theory was developed in October 15, 1981 by Ron Berler, a freelance journalist and Cubs fan. Berler posited in an article that "it is utterly impossible for a team with three or more ex-Cubs to win the series." Berler based this on a pattern that he observed in the post-1945 era; 1945 being the last time the Chicago Cubs made it to a World Series until 2016. Berler cited many examples of teams with three or more ex-Cubs on their teams that reached the World Series and lost: including the 1958 Milwaukee Braves, the 1966 Los Angeles Dodgers, and the 1978 Los Angeles Dodgers. The 1978 Dodgers, according to Berler, had lost the 1977 World Series with three ex-Cubs on their roster and seemed to be doing well the next season when they traded one of those ex-Cubs (

and, in the words of Berler, the "team suffered an immediate tailspin and barely beat Cincinnati to the pennant" (North was actually traded to the Dodgers first on May 17, and Garman was traded away three days later). The 1978 Dodgers lost the World Series to the Yankees leading to Berler's hypothesis of three ex-Cubs making it impossible to win a championship. In addition, the 1980 Kansas City Royals lost the World Series as well with 3 ex-Cubs. In the original article, Berler predicted that based on this pattern the 1981 New York Yankees would not win the

Explanation of the relationship

Berler relates the relationship to the inherent "cubness" that ex-Cubs take to their future teams. In the original article, he wrote that "the ballclub possesses eerie, bewitching powers over its players" and that "'Cubness'...is synonymous with the rankest sort of abject failure, and is a condition chronic among all Cubs, past and present."
Mike Royko Michael Royko Jr. (September 19, 1932 – April 29, 1997) was an American newspaper columnist from Chicago. Over his 30-year career, he wrote over 7,500 daily columns for the ''Chicago Daily News'', the ''Chicago Sun-Times'', and the ''Chicago ...
, who popularized the term in his columns in Chicago, wrote that cubness was a "virus" where "Three or more ex-Cubs could infect an entire team with the will to lose, no matter how skillful that team might appear." Berler adopted a similar explanation in later articulations, writing that the virus "attacks all who've played for the Cubs, even if only for a single day. There is no inoculation, no cure. When traded to another team, ex-Cubs become carriers of this debilitating disease—the ticks of baseball. Any World Series team infested with three or more of them turns addled and confused, losing all ability to win."


Modified Ex-Cub Factor

Mike Royko developed an additional hypothesis contending that "A team with no ex-Cubs probably has the edge on a team that has even one." The key evidence provided for this was the

Cases for the Ex-Cubs Factor hypothesis

Since 1945, of the 23 teams to reach the World Series with three or more Cubs players, only 4 have won the World Series (the 1960 Pirates, the 2001 Diamondbacks, the 2008 Phillies, and the 2012 Giants). Since its articulation in 1981, the Ex-Cubs Factor has been used to predict and explain post-season and World Series defeats for many different baseball teams. During the 1980s, the ex-Cubs factor was used to explain a number of losses by teams. It was used, in a letter to the editor, as a reason for the loss by the San Diego Padres (who ironically beat the Cubs to get to the Series) in the

Cases against the Ex-Cubs Factor hypothesis

Berler's study of the ex-Cub factor since 1945 revealed only one exception since 1945: the 1960 Pittsburgh Pirates, who won the World Series with three ex-Cubs on their roster. Berler contends that one of those ex-Cubs,
