We're finally at a point where there's enough data available for 2014-15 season that possession statistics are more than just variance. Unfortunately for the Kings, the team's numbers are downright distressing. After three years of being by far the best puck possession team in the league, the Kings have posted a 45.8% Corsi Tied (26th) and a 49.14% Score-Adjusted Fenwick (19th). Why have these numbers suddenly fallen after years of consistent excellence? Will things improve naturally, or do the Kings need to make major changes to the roster?

I don't pretend to have definitive answers to those questions, but I'll try my best. I think the best place to start is to look at how individual Kings are doing compared to last year and try to see who the culprits are.

The Forwards

One thing immediately becomes clear from the numbers: the Kings' best players are not the problem. When Anze Kopitar and Drew Doughty are on the ice together, the Kings are posting a 65.5% Corsi (in 63 TOI). That's a small sample and will regress a bit, but all indications are those two are playing as well as last year (60%). There are some other numbers indicating that the top pairing is fine - Doughty/Muzzin have posted a 58.8% Corsi together in 127 TOI (60.6% last year), and Kopitar's 56% Corsi at evens is second best among Kings forwards.

I don't think the second line is the problem either. Carter and Toffoli are clicking at 55.2% together. While that's not as good as they managed last year (61.1%), it's still quite good and easily outpaces the team average (even after adjusting for slightly favorable zone starts). A lot of the drop-off here (as for all Kings forwards) is probably due to worse defensive depth behind them.

The third line is an enormous problem. Jarret Stoll has been a complete mess. His 44.7% Corsi is horrible and nowhere close to what he did last year (55.6%). Basically, when playing with linemates not named Justin Williams, Stoll has gotten absolutely crushed (40.4% apart from Williams in 121 TOI). That's a big problem. Stoll plays a ton of minutes for the Kings; he has more 5v5 ice time this year than Justin Williams or Jeff Carter. The Kings are getting killed in those minutes.

The fourth line has been very good when Mike Richards has been on it, and absolutely awful otherwise. Richards has been a pleasant surprise this season - he's at 56% with Clifford and 52% with Nolan. Those are very acceptable numbers for a fourth line. When Richards is not centering that line, however, things get ugly fast. Nolan is a 40.2% away from Richards, and Clifford not much better (43.6%). This is mostly because Andy Andreoff has been unspeakably bad in his first NHL stint (39.6%).

Here's a quick table summarizing the forward data I found illuminating (all stats from stats.hockeyanalysis.com):

Selected Kings WOWYs, 2014-15 Notable Forward Groups 2014-15 TOI 2014-15 Corsi% 2013-14 Corsi% Change Carter-Toffoli 128 55.20% 61.10% -5.90% Clifford Without Richards 101 43.60% 54.90% -11.30% Brown Without Stoll 96 52.30% 57.70% -5.40% Stoll-Brown 89 41.80% 57.70% -15.90% Kopitar-Williams 74 55.60% 63.30% -7.70% Richards-Clifford 59 56.60% 49.80% 6.80% Stoll-Williams 53 54.90% 60.30% -5.40%

Some thoughts:

These are small samples so general trends are more helpful than individual cases. Those trends are clear: almost everyone does worse by roughly 6% or so. I think this is mostly because the defense, especially the 2nd and 3rd pair, have been much worse. It stands to reason that that would hurt all the forwards roughly equally.

Williams is still a puck possession god. He alone can rescue Jarret Stoll. Re-signing Williams has to be the number one long-term priority of the Kings. It's much more important even than Alec Martinez's contract.

Stoll is a complete mess, and Brown is not good enough to save him. Still, I think WOWYs show pretty clearly that the fault with the Stoll-Brown combo (who have by far the biggest drop) is with Stoll, not Brown.

Richards needs to stay on the fourth line. I don't think that number with Clifford is predictive (the sample size is pretty small), but the line seems to be decent with him. Without him, it's an abomination.

Never play Andreoff.

That about covers the forwards. There are major issues with the bottom six, but the good news is I think LA's best players are probably still good.

The Defense

I've already touched briefly on Doughty-Muzzin. They were excellent last year and they've been excellent this year. The problem is the other four guys. The Kings have not been able to assemble one decent pairing in the bottom four, let alone two. Regehr-Martinez (LA's de facto second pairing since Voynov's suspension) have been ineffective together (47% in 105 TOI). I think this is mostly Regehr's fault. Martinez is better away from Regehr but not exactly lighting the world on fire (51% in 97 TOI) - the Kings need a lot more from him, too.

Greene and McNabb have obvious trouble moving the puck and look like a disaster to my eye test, but they've actually been half-decent together (52.7% in 80 TOI). I am a bit skeptical that they can keep that up. After years of success Greene-Martinez has started off very poorly (46.8% in 66 TOI). McNabb's overall numbers on the year are OK (49.5%), but he seems to have lost the favor of the coaching staff and is barely getting any minutes at this point. Finally, although it's not particularly relevant to the current Kings, Voynov was just awful in his first six games before suspension (44.8%).

On defense, Regehr has been his usual self, that is to say a complete anchor in terms of puck possession. Unfortunately, Martinez and Greene have shown zero ability to drive play this season, unlike in years past. For Greene the problem might be age; for Martinez, it seems like a continuation of a worrying trend (he was worse Corsi-wise in 2013-14 than 2012-13, and worse in 2012-13 than 2011-12). Of course, for both of those guys it might just be a small sample thing they snap out of. McNabb has been serviceable out there but he can hardly carry a pairing.

Solutions

Here's how I would turn the Kings around.
