The Cubs haven't won a World Series since 1908 and, in that time, it's become a common exercise to inspect teams playing in the World Series for their relative ex-Cubness. As the theory goes, the more ex-Cubs, the worse a team's chance to win. Since the Bears haven't won a Super Bowl in almost 20 years, RedEye wondered: Over time, is there an ex-Bear factor since that last -- and lone --Chicago Super Bowl?
