When Two Worlds Collide: Normalized EV/PP/PK during "The Skid"
And one of those is a world of suck.
We all know the memes flying around this season regarding the Blackhawks, especially during the current 7-game 8 game skid. In a nutshell "EVERYTHING sucks" and the team, as constructed, has no chance to succeed. A tweak here or there will solve nothing. But is that true?
I broke down some basic numbers from the first 7 games of the losing streak in an attempt to see what's really been happening. Is it all on the goaltending? Is the PK costing the Hawks all of these games? Is it the PP? Do the Hawks suck even at 5on5? Is it the system, and therefore by extension, the coaching? Maybe it's a bit of everything?
By taking a closer look at the numbers, I believe we can narrow it down to what is hyperbole and what is likely fact.
First let's look at even strength...

If you've ever asked the question "What's the difference between a .849 Sv% over 7 games and league average goaltending?" you now have your answer. It's the difference between giving up 24 goals (what the Hawks actually did) and 13 (what some fictitious "average" goaltender would have done - and you know this goalie is fictitious because the idea of that ever happening seems so absurd).
The Hawks are actually out-shooting their opponents by a 4 to 3 margin at EV, or about 30 shots per game to 23. In not one game did the Hawks get out-shot at even strength. And in a few games, like EDM, CGY and SJ, the Hawks were dominant. Corsi exaggerated this even further. In a number of games the Hawks were over +20 as a team. (including the 8th loss against PHX). If you only looked at Corsi and shots, you'd think this team was on an point streak.
Think about that. The Hawks are getting 30 EV shots per game. That would probably be tops in the league if they did that nightly. The 23 shots against at EV would also be among the best in the league if they kept this up over the course of the season (Oh, wait. They actually do? I thought the defense sucked??). And this is during their worst losing streak in years.
And no, the SOG haven't been skewed much at all by the score. The Hawks have been close in just about every game. In the one blowout against Edmonton, the Hawks allowed the Oilers to pour it on in the end, so the normal increase in shots for the losing team never materialized. The Hawks actually had a larger shooting advantage in the first two periods, whereas 3rd period shots over the 7-game span have been pretty much even.
Yet, the Hawks are giving up 3.43 GPG at EV - at EV! - and only scoring 1.86 GPG. Not a good foundation when the PP and PK have been useless.
Now think about that one. Even though they are handily out-shooting their opponents they are getting outscored 2 to 1. That is a direct result of goaltending - both for and against. During the past 7 games, the Hawks goaltenders have been a dismal .849 while the Hawks shooters have faced hot and/or above-average goalies (.938). Basically, they've faced Henrik Lundqvist every night.
It's hard to win when you face goaltenders performing at that level. It's nearly impossible when, additionally, your own goaltending is below the Steve Mason-Dixon line.
When normalized for "average goaltending" the tape tells a different tale. League-average goaltending this year at even strength is .920. Using this percentage - and thereby removing the "goaltending effect" - the difference is astounding. The Hawks would have outscored the opposition by a half goal per game at EV.
In conclusion, this team does not appear to have a personnel problem - at least not at even strength. And the defense is actually limiting SOG. Facing above-average goaltending has cost the Hawks .53 goals per game, but their own goaltending has cost them an additional 1.61 goals per game. There is no team in the history of ever that could consistently overcome spotting the opposition 2.14 goals per game. Over the course of 7 games, that adds up to a difference of 15 goals.
Good news: the the opposing Sv% will regress. Bad news: The Hawks' may not.
(and there's a Leddy joke in there somewhere about him being the only Hawks player who has literally been "facing" below-average goaltending. Turn around Leddy!!)
Next up, not so special teams...

If you thought we had isolated the problem as "goaltending", well, not even close. The PP and PK are downright miserable, and it has little to do with goaltending. In fact, even when the numbers are normalized for goaltending (.880 league avg on PK), nothing really changes. And if we remove the last game against SJ, the Hawks goaltenders have had an above-average Sv% of .914 while shorthanded.
The hawks have been on the man advantage 19 times and shorthanded 22 times, yet they have been out-shot 47 to 11 on special teams.
The hawks have been on the man advantage 19 times and shorthanded 22 times, yet they have been out-shot 47 to 11 on special teams.
11 shots on 19 power plays??? Getting outshot 4 to 1 on special teams??? How does that compute when we just saw that the same team excels at EV?
It doesn't.
One often hears phrases like "The Hawks have too much talent to struggle like this on special teams." There's more than just a bit of truth in that statement. The Hawks are a top-heavy team. With such a large and highly paid core, there's not much of a middle class. Time will tell whether that approach works better than "spreading the wealth," but when you have elite talent, the rule is you do what you can to retain it. But I digress...
The point is, special teams is a chance to showcase that concentrated talent. Instead of rolling the usual four lines, you typically only roll two. The Hawks should have a clear advantage over most of the league here. "Average" results should be unacceptable. "Bottom of the league" is well beyond inexcusable.
The power play woes go beyond having a winger at the point. The PK woes go way beyond having Leddy out there. His numbers aren't much worse than anyone else's for a guy who shouldn't be out there in the first place. Sure, bringing in a PK defenseman should help, but probably not nearly as much as some seem to believe. And that's hardly the only questionable personnel decision.
This is systematic and the blame has to lie squarely on the coaching staff.
Bad special teams has costs the Hawks more than half a goal per game.
And finally, here's the overall picture...

Hawks are getting outscored by 2 to 1, but when normalized for overall league-average goaltending (.914), they would be be outscoring their opponents by .18 per game. So even with the dog-fucking-awful special teams, the Hawks could likely be .500 or better on this road trip; partly due to the opposing goalies' performances, but mostly due to Crawford and Emery.
In a nutshell, the Hawks hit the perfect storm. It's like flipping a coin and it coming up tails 7 times (now 8) in a row. Even though they're winning the skating battle 5on5, they're losing everywhere else at a rate not seen all season.
Storms pass, this will too. But the underlying problems remain. Fix the goaltending. Change the philosophy on special teams.
The first item might correct itself (however unlikely), be solved from within, or fixed by acquiring a goalie. The second item requires the organization to re-evaluate itself. And that's not so easy to do. Hopefully, the silver lining in all this is that the shit show on ice forces them to finally do so. Consider me not holding my breath.

Take your advanced stats and cram em
The problem is clearly Crawford…OH and Kane for not getting involved in scrums. There are the two biggest issues the Hawks have.
thanks for explaining this in a clear enough manner that even i can understand it!

Spectacular, CNS..

The second item requires the entire organization to re-evaluate itself.

"It could be worse: there could be blood squirtin' out of your nose"
"And that's 'Perfessr Mrs. Montador' to you...
My question is
If Crawford/Emery are such terrible goalies, what triggered it, because nothing in their past history suggests a collapse like this. Except for the fact, that is, that the defense has gotten rid of guys like Byfuglien, Sopel, and Ladd and replaced them with guys who aren’t doing much. Leddy has taken a step sideways if not back, Montador has not been played right by Q, Scott is sitll playing in the majors, and O’Donnell might as well be a traffic cone. Oh, yeah, and Hjammer, yeah, don’t get me started.
Stan deserves blame because the Rockford Shuffle with Campbell’s contract still on the books looks good compared to his free agency. Q deserves blame for being stubborn with the wrong part of the lineup and too willing to juggle everyone and everything to prove he really IS Jerry Krause’s love child. Replace Q with Haviland for the rest of the season. Put Stan on notice. ds

I watched Craw in Rockford
What I saw there is a goalie that was continually getting peppered thanks to bad defense in front of him. A couple of games, I think he saw 50 shots, and he had way too many games with 35 plus saves to blame him for much.

I love the work and post
But my biggest issue I have with your comparison analysis is, it seems like a form of regression to the mean, which the more I look into it in sports, the more I hate the concept of it being used in sports. What you show is an ideal comparison to an average team, but no team is ideal or truly average.
What it does show, is the Hawks are playing worse then an average team in many aspects, which is good to have pointed out. But it does not show they why, only the where. We already knew the where it is the why that is really the bitch to figure out. Is it the Goalie? Is it the Defense? Is it the Forwards? Is it a combination of two or three of them? No matter what the answer is of those four options, we can get the same result.

Not at all
Because I do, just that I do not believe it is the sole and final reason of the level of sukiness we are seeing. I still put a big chunk of blame on the defense scheme as a whole along with the Goalies blowing Goats.

The thing is though that Occam's Razor applies
The margins of success/failure within any given league are quite small, certainly at the top level league of any given sport. It doesn’t take being terrible at all aspects or even most aspects to make a team do a lot of losing. Being very much below the league’s mean at just a couple of major areas is plenty.
Put another way: the factual case that CNS lays out seems quite persuasive that (a) the Hawks’ goaltending is well below NHL average and (b) their special teams are going even worse than that. So then the question is, could being terrible at two of the game’s major elements be enough to explain these W-L results even if the team was performing fair or better in all other major elements?
My sense is yes, which if correct then logically means that I have to back off of my recent heavy criticism of the non-special-teams defensive play. Which I have to admit I’m having trouble doing after watching these recent games but…life has taught me many times over how much and how often the eye test deceives. So…well it’s thought-provoking at a minimum.

We may not be giving up a lot of shots, but recently many of them seem to be 2 on 1's and 3 or 4's on 2's.

This deserves mention, true. I know what you think about shot quality, CNS, over the course of a season … but we have been giving up an inordinate odd-man rushes that might account for some (granted, only some) of this. Enough to make a difference over just 7, now 8, games?
www.mjt.org
I was gonna say the same thing
And go on to say that it may explain some (20%?) of the difference in sv%, but that’s an awfully big gap.
We like our people!
It is a big gap … but this is definitely a problem with sample sizes so small … as everyone knows, including CNS. The analysis is sound, but there are a lot of variables that can intrude over just 7 games. I don’t have the time or energy to dream them up … but this odd-mann rush comment by ilovehawkey put it into my head.
On another note, I’m a really shitty typist.
www.mjt.org
Again, I firmly believe most of this is goaltending effect, not all, but most
Maybe it makes up 20% of the difference, like cliff states, but I think even that is even generous. I haven’t been tallying solely odd-man rushes, but I have looked at all shots from within 10 ft, which is congruent. Hawks have had more shots from the low slot than their opponents over the 8-game span.
A good example is PHX. The overall narrative of that game is that PHX was getting odd-man rushes out the wazoo, but the Hawks couldn’t get the puck down low. Also, due to the Hawks taking risks in an attempt to get back into the game, they gave up a lot odd man rushes (which are included in my tally). Yet…
Emery: 4 saves from within 10 ft
Smith: 10 saves from within 10 ft
Why only 4 saves for Emery? Because 3 went in. Hawks’ goaltending has done a great job of training us over recent years to expect anything that gets past the defenders to go in. That’s just not the case with good goaltenders. Shots like Keith’s wrap around would be sure goals against CHI, yet nary a mention of it during the game because Smith went post to post so quickly that the shot wasn’t that dangerous.
I’m seeing goaltending, especially Corey, that only has the ability to make one save. Yet I watched Smith stop 3 consecutive shots and never lose his net, never look out of position, never look desperate. It was like they weren’t even prime scoring chances because he was right there in front of each shot. Now contrast that with the desperation and floundering you see on our side.
And the ironic part of me using the PHX game as an example is that it’s the only game where I felt the Hawks defense did give up too many prime scoring chances. But the numbers show that we just might not be very good at counting, due to the goaltending effect. Also, I believe most people recall the easy PK goals and project them onto the 5on5 part of the game. IMO, the Hawks aren’t doing anything too differently 5on5 than anyone else, or giving up more prime opportunities. They’re just stopping less.

I don’t disagree, and wasn’t disagreeing. I just meant that shot quality IS a factor in small sample sizes. I agree with you that it isn’t over the course of a season, but in 7 or 8 games it can be. The shots Smith saw down low vs the ones Emery did … what was teh difference? Chicago’s weren’t odd-man rushes where the goalie had to beware both pass and shot, only shot. Maybe?
But ya, I do agree that the goaltending has been the main issue over the course of the season. i just don’t think we’ve been as sound during the losing streak as the stats may suggest … because it’s a small sample.
www.mjt.org
Yeah, I agree
I was actually just coming back here to waffle a bit before anyone replied. Heh. Cliff’s 20% figure is probably pretty accurate after I thought about it a little more.
But that’s still only a couple of goals since every odd-man rush shouldn’t result in a goal. And I can think of numerous examples during the skid when the d-men still got back for decent coverage or the shot wasn’t that dangerous and they still went in.
All in all, I firmly believe it’s just a case of everything going wrong at once. The goaltending isn’t THIS bad, but no way is it good enough to go deep in the playoffs unless they give them lobotomies.

I agree that our goaltending is the biggest problem
When we turn it over, it tends to find the back of the net. And when Crow loses the crease, how come I can get off my couch, jump up and down 10 times screaming at the top of my lungs and he still isn’t back in the crease yet? I have not pulled the stats for this yet, but I’m pretty sure it has happened at least five times in the last month.
Thanks for this great post CNS, man you put a lot of time and effort into this stuff and I truly appreciate it.

sample size
Including the Phoenix game:
262 shots, 15 goals
236 shots allowed, 33 goals allowed
Not tiny.
I
We like our people!
You stated that the shots weren’t skewed by being the trailing team, but I’m curious if you looked into it or if that was just an eye test. I liked what you did and I don’t disagree that 5 on 5 they have been good, but it just seemed a bit hand wavy to say trailing had no effect on the shots since they have hardly led in any of these games.
Just half ass calculating they never led in Phoenix and trailed by 2 for 55ish minutes, never led in SJ and trailed by 2 for 15ish minutes or so and were tied for only 10ish minutes, Col was a pretty even game mostly played tied except the third, Calgary was similar trailed in the third but tied most, Edmonton was the only game they led for significant time before imploding, Vancouver was pretty much tied the whole game, Nashville at home trailed by 2 for 30ish minutes and by 1 for another 20ish, Nashville road game trailed by 2 or 3 for the third. Not an exact calculation, but they’ve spent about half their time trailing and about a quarter trailing by (granted the Phoenix game really skews it) and with only maybe a period or two in the lead, so it would surprise me to see no effect of trailing showing up in the stats.
A few things...
First, if you look at the graphs, PHX wasn’t included in these results. I KNEW someone would still mention it!
My intent was to not get too in depth. The score effect on Corsi is so minimal that in general it could never diminish the fact that the Hawks out-shot their opponents and therefore weren’t getting run out of town as some narratives state.
3 yr avg Corsi for a trailing team is .533. For SOG (SF/(SF+SA)) it is .544. So if a team was leading from the first second of a game, in a 60 shot game played entirely at EV, the trailing team should on average out-shoot their opponent by 5.3 (32.6 – 27.4). Now let’s just say they were trailing half the game, now the difference is down to 2.65. The avg NHL game has 11.2 mins of special teams time. So divide that in half, 5.6 mins, or 18.7% of that 30 mins. So 2.65 – 18.7% (.50) = 2.15.
Even if the Hawks were losing for half of every game, it should only affect the SOG differential by 2, on average. So instead of out-shooting their competition 209 to 159, they might have only out-shot them 202 to 166. It doesn’t influence the story being told here.
Lastly, in a small sample size like this, I think one really has to go by the eye test. Was the team sitting on a sure lead? (the 1st NSH game) Was the leading team still attacking? (EDM, SJ, CGY) Were they leading by only 1 for most of the game which has little effect on SOG? (most games) Was the game mostly tied? (VAN and a few others) Was the game closely contested until somewhere in the 3rd period? (5 of the 7 games)

Well CNS
I didn’t even read the fanpost, but I have an issue with this comment.
Stats or eye test? Which is it?
Or are you saying you see it this way, therefore you must prove it with some “Normalized stats”
It all looks good and I’m sure it makes perfect sense.
One last thing, why do we even watch the games if it is always going to normalize? It’s predetermined anyway, so everybody move along

I need to check Fanposts more often
This is good work, I always appreciate attempts to cut through the CW.
Also, I didn’t realize that the PK was so all-around awful. We’re used to seeing the PP alternate times of plenty with times of want, but I admit I thought that the PK problems were mostly goaltending.
But it turns out that the PK has been worse than I thought for much longer than The Skid. For the season, they’re last in the league in shots against while on the PK. It’s a good thing they’re shorthanded less than most teams or this would really be ugly.

"Basically, they've faced Henrik Lundqvist every night."
I’d argue that’s more the Hawks making them look like Lundqvist. Except for Mike Smith, who isn’t included in your post, I can’t recall any opposing goalie who really had to come up with huge save after huge save. No traffic, no second and third opportunities, no forced movement, make for a relatively easy night for the other team’s ’tender.
The Blackhawks goalies suck and for all the talent the forwards posses they aren’t putting in the requisite work to dent the twine.
We were somewhere around Barstow on the edge of the desert when the drugs began to take hold.
I think Crawford is unlucky or in terms we have heard
has no luck right now.
If he could get some luck, he would be fine.
Luck is what he needs

Thanks for doing this. I do feel a bit better but am slowly coming to the realization that Q might need to go if the Hawks don’t show improvement in the next five games, no matter how many they win.
Ha ha
Their next five includes games against Nashville, Saint Louis and Detroit. If they win all five of those, I’ll be starting the “Q for Coach of the Year” bandwagon.

This was well done.
It’s encouraging that the stats back up what my eyes have been seeing. I’ve got a few buddies that have been asking, “what’s up with the Hawks?”. They don’t watch their games, just the highlights, and they think I’m preaching madness when I try and break things down for them.
You are next.
