I agree with a qualifier: I'd rather play the Brewers or Dodgers than San Fran but I would rather play San Fran than Atlanta. While the Giants have a great rotation, the Braves' rotation is pitching extremely well and they have both a better bullpen and (at least the past month or two) a better offense.
Atlanta is a really, really good team that is playing as well as anyone lately. The Brewers could still sneak in, but the Braves are the team that probably scares me most. Ironically it's also the team I'm rooting for most outside of Cincinnati as a surrogate Atlantanite.
