I guess to be clear, none of the lines are really struggling. They just aren't living up to billing and our (certainly) unrealistic expectations. All 4 lines were above average tonight. The worst line tonight was the Danault line, the best was the Kopitar line again.
But even the Kopitar line is starting to see some negative trends creeping in. They were the only line to get outshot tonight, the best in that regard was the PLD line. I'm also of the mind that they aren't going to do anything about it in the near term, but the PLD line is failing the eye test right now.
Or hell, I'm sure we are just overanalyzing. Maybe it's just the trend in matchups this week that's making them look bad. Who knows.
The Flyers game should be interesting as I think the are playing better than their record indicates. But they are a better matchup for the Kings and play tomorrow night, so there is that.
