They didn’t play like it and the dodgers took them to 7 games last year with the dodgers pitching basically giving the astros two of the 7 games.
The dodgers starting pitching and bullpen is better than Houston’s was this post season. Astros have some very good hitters but I don’t think they faced the kind of pitching the dodgers did in the NLCS
The Dodgers also weren't pitching to the Red Sox. The Dodgers are very good but I agree with Masscobra, if the Red Sox don't win it'll be an upset.
