I have a few friends that are Cubs fans and as a Mets fan, there is an inherent disdain for the Dodgers. If the right teams win and lose tomorrow, they play for the Wild Card.
One day you win 90+ games and are working toward a playoff birth (the wild card game IS NOT -at least it shouldn't be- considered playoffs), the next you end up in the same place as the 100 loss Orioles.
Baseball is a fickle bitch.
