Ideally, the Braves win one game in Atlanta and finish the Dodgers off in Los Angeles, only seeing Clayton Kershaw once.
However, assuming Atlanta does put Los Angeles up against the wall in Game 4, there's also the chance that Kershaw pitches on very short rest. And if Medlen beat him in Game 1, the best pitcher in baseball will not only be fuming, but will be pitching for his season at home in front of a packed Chavez Ravine.
And then the Braves would get Zack Greinke in Game 5.
If Ricky Nolasco goes in Game 4 and the series comes back to Atlanta in Game 5, Kershaw would still be waiting to pick the Braves apart in the series' deciding game.
Atlanta can't see Kershaw twice. It seems impossible, but Atlanta's best chance to win this series is to win two of the first three games (against Kershaw, Greinke, and Hyun-Jin Ryu, no less) and hope that Ricky Nolasco pitches in Game 4.
Otherwise, well...I don't want to talk about it.
