The NL playoffs in 2018 are filled with teams that have not seen the postseason in a long time. Colorado has not made a playoff series since losing in the NLDS in 2009 and the Braves have not seen action after game 162 since 2013 which was also the last time they finished with a record above .500. For Milwaukee, the story is the same as the first two teams- they have not been to the playoffs in a significant amount of time, their drought spanning back to 2011.
But, despite poor showings in the past, the playoffs of underdogs is stacked with quality lineups and excellent pitching.
