Edmonton Scoring Chances, Year to Year
The best thing about the work that Dennis King (and now others) is doing on scoring chances is that we're beginning to get some data to work with. His work with the Oilers numbers last year was excellent, but limited. Now that we've got a second season to work with, we can start to do some analysis on these datasets.
Knowing that the rest of the Northwest is being tracked this year is exciting because we'll be able to do some intra-divisional comparisons. I've decided to take a look at the Oilers at the quarter pole this year and compare those numbers to the total chances from last year. Things look bleak, especially for the veterans on this club. Shawn Horcoff, Fernando Pisani, Steve Staios, Jason Strudwick, and especially Ethan Moreau look incomparably bad by this metric. Even though there has been hand-wringing over the amount of kids on the team (including some by me), there are some kids that are doing much better than I thought.

The above chart compares those scoring chances by player. I've compared Gilbert Brule to Kyle Brodziak because he's been given pretty much the same job that the departed Brodziak had at even strength last year. I've also compared Ales Kotalik to Mike Comrie as they've had similar jobs at even strength.
There is some interesting stuff going on here. The chart shows 24 comparable players and 17 of them have a lower chances for per 15 value. 19 of them have a higher chances against value. We can safely say that this team is worse at evens this year. No doubt the injuries and flu have something to do with this, but it should be noted that the team is bleeding at evens this year.
Brule is not handling the role as well as Brodziak did. In fact, he's giving up a half of a chance more per 15 than Brodziak did - if he gets similar time on ice, that amounts to three extra goals against this year. Prior to his injury, Ryan Stone was doing just fine - it will be interesting to see how Quinn handles him when he's healthy again.
Horcoff's play has been brutal by these numbers - he's off a full chance per 15 minutes. That's an extra eight goals against at even strength this year. Moreau is off by the same amount, but he is now surrendering 2.594 chances per 15 more than he's creating, easily the worst among regulars on the team and given his performance last year, is a signal that he may be done.
By far, the biggest falloff this year has been by Andrew Cogliano, as he has seen his differential slip by over 1.5 chances / 15 this year, to -1.726.
For all of the accolades that Ladislav Smid has received, those accolades don't mean much in this case. His chances differential is the same as it was last year. I have a hunch that if his chances were broken out between his time spent paired with Lubomir Visnovsky and time without, you'd see a rate that was one of the best on the team with Visnovsky and one of the worst without Visnovsky.
Comrie has been a better player at even strength thus far. Dustin Penner's CF and CA are both up this year, as are Ales Hemsky's total chances. Souray, though limited this year, has strikingly similar numbers. Ryan Potulny had success in his extremely limited time last year, and he's having success again this year in extremely limited time.
Lastly, I don't believe that Theo Peckham is, or was, healthy, at least during his callup this year. The foot must still be bothering him as he was just abysmal by this metric.
Author's note: Vic has determined that the goal / scoring chance rate is 1/7 in his findings thus far. All GF/GA math in this post is based on that.

Fairness and accuracy ... .
Of course, and with all due respect, when you say Cogliano’s scoring chance plus/minus has has fallen off, that’s not entirely fair or accurate.
A fair and accurate statement would be: The Oilers as a team have a worse scoring chance differential this year as compared to last year when Andrew Cogliano is on the ice.
Is Cogliano doing worse as an individual creating scoring chances or stopping them? This stat tells us many things, but it does not tell really help us answer that question.
Who Cogliano plays against could influence how the team does in scoring chance plus/minus when he’s on the ice, of course, but in his case, I’d say it’s who he is playing with that is influencing how the team does when he’s out there.
And a stat that tells me Smid isn’t doing better this year, well, I’d say that the stat is correct, that it’s telling us the team has the same scoring chance differential when Smid is out there, but that it’s not necessarily capturing Smid the individual and how he’s playing this year or last year, for whatever reason.
I love this stat as a team stat, and think it’s hugely significant as a team stat, but I like to be careful (finickey ;) ) about how I phrase the results, as, again, it’s essentially a team performance stat, not an individual performance stat, IMO.
He is playing with Ethan Moreau.

He is playing with Ethan Moreau.
His most common linemate last year was Ethan Moreau too.

However moreau has been worse this season

I was going to bring up a similar objection. Given how the team trends, the fact that Smid is treading water means he’s actually doing much better. (A better defensive partner will do that for you, of course, but his D partner is down 0.5 CD/15, so make of that what you will.)
I’m not sure how the hell you tease individual performance out of this, but boy howdy, this team is haemhorraging at EV.

I think pretending it tells us nothing about individual performance is silly. Sure, it’s a “six-man unit” stat, but the only consistent member of that six-man unit in the “Andrew Cogliano” column is Andrew Cogliano. There needs to be a bunch of context added if we’re going to make a judgment on what kind of a hockey player Andrew Cogliano is (linemates, opposition, zone starts and so on) but that’s true of all stats. Even individual ones like “goals” or “errors.” There needs to be a bunch of context for those to be meaningful as well. Scoring chances are an indication about Cogliano’s play and they’re one indication (among many) that he’s struggling. And really, how many of the players whose SC differential is worse than -1.5/15 would you say haven’t struggled this year?

Peckham was abysmal by any metric in his call-up this year.
-6.35 G/60
-27.9 S/60
-48.24 Corsi/60
-7.911 SC/15 (or -31.64 / 60)
He was completely out of his depth. I certainly hope (and believe) that the injury affected his performance, if not he should be removed from the Top 50 prospects list.

Well, Peckham’s still one of the top fifty prospects on the team, surely. I mean, he’s better than Bryan Pitton.
I’m better than Bryan Pitton.

yeah, I said that for effect. He was that brutal. I mean, Sebastien Bisaillon was much better in 2007.
I sincerely hope it was the high ankle thing that was the reason. Peckham playing tentatively is never going to work.

Ooops
I meant that Cogliano is playing with Ethan Moreau … I garbled my post a bit.

These numbers mean nothing without zone context.
Defensive zone start versus neutral zone start versus Offensive zone start.
Same as Quality of comp per zone start.
Point Production modified for zone start.
GA for zone start.
The major flaw of all these stats is we should have three sets. How is a player versus the lague average in each zone start.
With horcoff having one of the toughest zone starts in the league. Of coarse the scoring chances are going to be less than favourable.
No kidding sherlock.
Analyze by zone then we have something.

If you’re trying to defend Horcoff, Zonestarts aren’t the hill to die on. This year’s ZS% has been easier than last year’s.

Now, Dustin Penner’s zonestarts on the other hand…

I think saying they mean “nothing” is going a little far but yeah, just like any other stat, when you add more information they become more meaningful.

Zonestarts
Rickibear. Are you sure that all goals, and the most dangerous scoring chances, come from breakdowns in the defensize zone? If that’s the case, then zonestarts are hugely significant.
But what if many goals start because of a mistake in the offensive zone, errors that lead to a significant momentum change, even to an odd-man rush at the greatest extreme?
That would mean that many times it’s not such a huge advantage to have a faceoff in the offensive end, because that is where you are curiously vulnerable to making a mistake that will give up a dangerous scoring chance.
I’m not saying I have the answers here, and I agree that zonestarts is an extremely interesting idea, and that on the face of it, it would make sense if you’re out for a high percentage of defensive zone faceoffs that could well spell trouble.
But I am saying hockey is an extremely fluid and dynamic game, not static, not like NFL football where field position is king. Ice position is important, yes, as almost all goes happen from a shot in front of your own goalie, but they very often come out of a mistake that has happened earlier, way up ice.

Funny what you see and what you remember
I am always watching for consequences of referee intereference, and I would have a slightly lower estimate of how often the puck winds up in the net. Haven’t got an exact number, but it’s something below 5%. :)
I also watch for the same thing on a constitutional error, for example a faceoff in the wrong zone. If it’s in Oilers end I always stay mad until they clear the zone, so it’s easy to track. But clear the zone they do, > 95% of the time.
But … those times you do get burned, it really Burns.
