Chicago Cubs: NL Central foes
The NLCS is set, and this time, the Cubs will sit at home after participating for three straight years from 2015 to 2017. Worse yet, their NL Central rivals, the Milwaukee Brewers will be there instead, battling the Los Angeles Dodgers for the pennant.
For anyone but Cubs fans, the Brewers are a great story. They are a small market team that acquired tons of talent in the offseason and first half and stole the NL Central title in the tiebreaker game after two straight division titles for the Cubs.
But as a Cubs fan, the last thing you want is to face the defending World Series champions in your division next season, so that rules out Milwaukee.
