but it's also very overstated IMO.

Many of his bad games are really good games through 6 innings, but then the Dodgers trot him out for the 7th (because their bullpen has been so weak), even though he's often pitching on short rest, and he gives up a few runs.

The Dodgers bullpen has also failed him by allowing an unusually high percentage of runners inherited from Kershaw score.

I'm not saying he's been great. But Kershaw has performed better in the postseason than most people give him credit for.
