It would be a shame if somehow the Cubs were to win the World Series before the 100th anniversary of their last such win. I believe it will be the 2008 season for such "celebrations". Red Sox will have that honor in 2018. For the record the Cubs have won 2 world series and the Red Sox 5 including the very first. Many franchises would love to have that.
Every team is entitled to a bad century every so often.
