Taking out the 6-0 early home stand, the Kings are 9-10-6. Quick has a .916sv% in those 25 games, which isn't terrible, but isn't great either. They won the Cup last year with him at a .911sv%, but they also had 4 guys at or close to a point per game. In these 25 games, Muzzin is actually leading the team in point with 15. Stoll has 11, and Kopitar has 10, which is the same amount as Richards. Carter has 8 points in 25 games, and is tied with Stoll at 3 goals in that span. Gaborik has been hurt, and is scoring under .5 point per game. Every forward is, except Williams, who has 14 points in 24 of the 25 games.
Outside of that 6-0 stretch, when one line, and one goalie were stupidly good, the Kings have just been decidedly average this season. Maybe even less than average, since with a 9-10-6 record, they have only 24 points in 25 games played.
We all have our theories as to what's going on. We obviously can't really know though. As frustrating as it is, I'm going to stick with the hangover theory for now. The Kings haven't played themselves completely out of anything yet. They might be adrenaline junkies at this point. Especially after what they did last year. Down 0-3, beat Anaheim, take down their mythical dragon in Chicago, some crazy OT's against the Rangers.
Or, they're simply just not getting enough out of Kopitar, Carter, and Gaborik.
We know what the players are capable of, and yet pretty much everyone has been...just there this year. Win one, lose one. Play well, play not as well. They've earned the benefit of the doubt. If you had said Kopitar would get 0 goals in a 7 game series against Chicago, nobody is thinking they win it. It's a weird team, it's a unique team. Just have to wait and see how it evolves.
