Another incredible series for Connor McDavid. The Oilers were dominant whenever he was on the ice at even-stregnth (5v5), outscoring the Flames 14-5 over the course of the series. Remove that first game, and the Oilers outscored the Flames 10-1 in games two to five with McDavid on the ice. Just outstanding.
And while the Oilers thrived with McDavid, the Flames really faltered because their star players struggled. Gaudreau, who had an incredible regular season, posted an on-ice goal-differential of -3 (4 GF, 7 GA) at even-strength, a 36% goal-share. In games two to five, Gaudreau’s on-ice goal-share was only 25% (2 GF, 6 GA) – posting a 53% Corsi For percentage, but only a 48% expected goals-for percentage. These are significant drops from his on-ice numbers in the regular season, when the Flames posted shot-share numbers above 58%, including an expected goal-share of 60% with Gaudreau on the ice.
Here’s how the two teams performed in the second round at even-strength (5v5):
Expected Goals For%
While it looks like the Oilers were out-shot by the Flames, it becomes evident when you dig into the data that the Oilers were the much better team when it came to generating quality chances as reflected in their expected goals for percentage, and they gradually improved over the course of the series.
Calgary put more emphasis on quantity, taking shots from lower probability scoring areas and trying to generate more rebounds and second chances. Their tactics did seem to be effective as their team shooting percentage was at 10%, slightly higher than what they posted in the regular season (8.52%, which is around league average) and more than double what their shooting percentage was against Dallas in the first round (4.65%).
And make no mistake, the Oilers goaltending was pretty poor against Calgary, with Mike Smith posting a 5v5 save percentage of 90.2% and a -1.65 GSAA. It was a concern heading into the series as the numbers he had posted in the first round were higher than expected, so regression was going to catch up eventually. Just never know when it’ll happen and how much will occur. The only saving grace for the Oilers is that Jacob Markstrom was significantly worse in the series, posting a 5v5 save percentage of 83.9% and a GSAA of -9.15. Both goalies were around the 92.5% mark in the regular season.
Here’s how the Oilers forwards and defencemen did against the Flames.
Pretty evident that McDavid was the key driver for the Oilers success this season, as the club out-scored the Flames 14-5 with him on the ice, but were out-scored 5-10 without him. And the Oilers struggled to generate shots and scoring chances without him over the course of the series, posting a Corsi For% of 39.60% and an Expected Goals For% of 44.27% . Having said that, the Oilers did gradually improve without McDavid, posting an Expected Goals For% over 52% in games four and five – something they can hhopefully build off of heading into their series against Colorado.
Expected Goals For% (5v5)
One player that stood out to me in the series against the Flames was Ryan McLeod who played against varying levels of competition, and posted a Corsi For% of 55% and an Expected Goals For% of 60%. In game five on the road in Calgary, McLeod playing just under five minutes against Gaudreau (about 38% of his total 5v5 ice time), and posted a Corsi For% of 76% (10 CF, 3 CA) and an Expected Goals For% of 85%. That’s the productivity the Oilers will need from McLeod and his linemates if they want to have success against Colorado. And if Nugent-Hopkins can continue anchoring a second line with Hyman and Puljujarvi, and if the Oilers can get league average goaltending, it should be a competitive series.
With the second round about to start, a quick look at how all of the playoff teams performed up until this point. The table below has each team’s even-strength (5v5) shot-share numbers, goal-share, team shooting percentage and team save percentage from the first round, and is sorted by goal-share. I’ve also included each team’s special team numbers, which includes their rate of unblocked shot attempts for (Fenwicks) on the powerplay (PP FF/60) and their rate of goal-scoring per hour (PP GF/60). And also the rate of unblocked shot attempts against on the penalty kill (PK FA/60) and the rate of goals-against per hour (PK GA/60).
We know the Oilers did well in terms of shot-share metrics at even-strength (5v5) in their series against the Kings, thanks in large part to the play of McDavid. Aside from their inability to out-shoot and out-chance the Kings without McDavid on the ice, the team’s overal shooting percentage was also below what they had posted in the final twenty five games of the regular season (9.01%) – an indication that their other top line players are struggling or injured.
The other concern for Edmonton heading into their series against Calgary is that the Flames have performed quite well with and without their top line on the ice – both in the regular season and so far in the playoffs. In the last twenty five games of the regular season, the Flames top line featuring Johnny Gaudreau dominated at even-strength, posting some of the best shot share numbers in the league and a Goals For percentage of 68.29%. Without their top line, the Flames shot-share numbers were still excellent, and they out-scored opponents 34-30, a goal-share of 53%.
Flames (5v5) Final 25
Expected Goals For%
The Flames shooting percentage took a major hit in the first round against the Stars thanks to a strong performance from goaltender Jake Oettinger. And that included the top line who saw their on-ice shooting percentage fall from 12.77% at the end of the regular season to 6.65% against Dallas in the first round. Similar issues for the team when the depth players took to the ice as their shooting percentage dropped from 6.88% in the regular season to 3.53% against the Stars. But as we see in the table below, the Flames continued to dominate the Stars when it came to controlling possession and scoring chances as reflected by their strong shot-share numbers. And the Oilers should probably expect the same in the 60-65% of 5v5 ice time when McDavid isn’t on the ice. The Flames have a more talented roster than the Kings, so it’ll be imperative that the Oilers depth players prevent as much bleeding as possible.
Flames (5v5) vs Dallas
Expected Goals For%
Something else to monitor is the special teams.
While the Oilers penalty kill had outstanding results against the Kings allowing only 3 goals in 44 minutes (4.10 goals against per hour), they allowed one of the highest rates of shots and scoring chances against and relied on their goaltender to bail them out – an issue that’s carried over from the regular season. The Kings are a heavy shooting team as indicated by their rate of shot attempts in the regular season, so that might have inflated numbers. But knowing Smith’s past performance and injury issues, I’d be a little concerned if his work load remains high. And it’s something the Oilers should expect considering the Flames generated the third highest rate of shot attempts on the powerplay in the regular season, and they maintained those numbers in their series against the Stars.
Also worth noting that the Flames penalty kill in the regular season was excellent, as they allowed the third lowest rate of shots against in the league and the sixth lowest rate of goals against – and they peformed quite well against Dallas. The Oilers though appear to have the Flames number, as they scored 7 powerplay goals against them in the regular season – at a rate of 18.71 goals per hour.
Lastly, the goaltending.
Mike Smith posted solid numbers in the first round, posting a 93.70 save percentage and a +2.61 GSAA, third highest among the 17 goalies who played at least 100 5v5 minutes in the first round. The question now is if he can maintain these levels through another series, especially against a good possession team that can generate offence in waves and across more than one line.
Here’s how the Oilers team 5v5 save percentage, in rolling seven-game segmenets, looked in the regular season. I’ve added a blue line to show what the team’s save percentage has been so far in the playoffs.
What we see here is that the Oilers goaltending has shown spurts over seven game sets, but it’s typically regressed to league average levels soon after, which is what I would expect over the next series against a team like Calgary. Being league-average is still good and can win you games. It just won’t steal you some wins when the rest of the roster might be struggling. I have a feeling the Oilers will need that considering the injuries and the lack of production without McDavid on the ice. So hopefully Smith, or Koskinen if need-be, are up to the task.
Can’t say enough about Connor McDavid’s performance in the series against Los Angeles. Over the seven games, the Kings had no answers for McDavid, as the Oilers dominated puck possession at even-strength (Corsi For% of 63%) and the share of scoring chances (Expected Goals For% of 73%) with him on the ice. The results: in the full series, the Oilers outscored the Kings 11-4 at 5v5 with McDavid, and 5-1 in the two must win-games.
The Oilers struggled without McDavid on the ice, regularly getting out-shot and out-chanced, posting shot-share numbers below 48%. Four of the five goals they managed to score happened in the Oilers 8-2 blowout of the Kings in game 3. Between games four and seven, which included the two must-win games, the Oilers scored 0 even-strength goals without McDavid on the ice and allowed four.
Oilers (5v5) Round 1
Expected Goals For%
There were games in the series where the Oilers did out-shoot the Kings without McDavid on the ice, as shown in the graph below. The problem is that they when they did control the flow of play in games and keep pressure in the offensive zone, they couldn’t convert those into actual goals – an indication that key players like Draisaitl have been playing hurt since the end of the regular season.
The Oilers were clearly struggling between games one to five, so it wasn’t susprising to see McDavid play over 42% of the team’s total 5v5 time in games six and seven – an increase from the 33% share he saw over the first five games of the series and over the course of the regular season. It’ll be interesting to see if Woodcroft continues deploying McDavid excessively, or if he tries to scale things back in games one and two against Calgary to see if the rest of the roster can find their production. McDavid is just playing at such a high level right now, and we know others are playing hurt, so it’s hard to imagine his share of 5v5 ice time go anywhere below 35%.
Quick summary of how the two teams matched up over the seven game set.
Los Angeles Kings
Expected Goals For%
The issue for the Kings in the regular season was their lack of finish and it definitely carried over in the playoffs. In the final twenty five games of the regular season, their 6.99% shooting percentage was the worst in the western conference, only slightly better than the 6.58% they posted over the seven game series. Their goaltending was better in the playoffs than it was in the regular season – which didn’t susprise me considering Quick’s numbers were actually pretty solid over the final stretch of the regular season.
Smith was solid too, posting a +2.61 GSAA, third highest among the 17 goalies who played at least 100 5v5 minutes in the first round. And just ahead of Quick who ranked fifth overall with a +2.22 GSAA.
And finally a quick summary of how the individual players performed over the seven games.
Worth repeating again that Draisaitl and Hyman shouldn’t be playing together. In 56 minutes at 5v5, they were crushed by the Kings, posting a Corsi For% of 41.50%, an Expected Goals For% of 34%, and getting outscored 5-1. Playing away from Hyman on a line with McDavid, things are a lot better for Leon as he’s posting stronger shot-share numbers (61% Corsi For and 70% Expected Goals For) and a +2 goal differential. And Hyman I think is bound to break-out soon – he’s been difficult to play against and posting similar on-ice shot-share numbers to Draisaitl’s.
First, a quick look at how the Oilers have performed this series at even-strength (5v5) on home ice and on the road. They’re definitely getting better results on the road, and it’s a little concerning that their numbers aren’t as solid at home with their expected goal share being 46.60% and their actual goal-share being 38.46%.
We also know the Oilers are struggling in this series at even-strength (5v5) whenever McDavid isn’t on the ice. In their six games against Los Angeles, the Oilers have out-scored the Kings 9-4 with McDavid on the ice, but have been out-scored 8-5 without him. And that’s due in large part to their inability to control the flow of play and out-chance the Kings without McDavid, as the club has posted a Corsi For% of 47.35% and an Expected Goals For% of 44.67%.
What’s especially concerning is how poor the Oilers play at home without McDavid – not exactly what you’d want to hear heading into a game seven in Edmonton. In the three games at home this series, the Oilers without McDavid on the ice (about 65% of the team’s total 5v5 ice time) have scored only one goal at 5v5, and allowed six. Their underlying shot-share numbers have also seen a drop when they play in Edmonton, especially their Expected Goals For% which is 48.32% on the road but 39.97% at home.
There were three games this series where the Oilers posted an Expected Goals For% above 50% without McDavid on the ice – games 2, 3 and 6. Those were also the games that the Oilers won. No surprise that if the depth of the team is holding their own in terms of puck possession, shots and chances, the Oilers have a much better chance of winning games.
Compounding matters is the fact that Mike Smith has struggled at home as the Oilers 5v5 team save percentage at home is 89.33% – the worst among all playoff teams. Smith’s numbers have been significantly better on the road this series, with the 5v5 team save percentage ranking third overall with 95.60%. If the Oilers can spend more time with the puck and in the oppositions zone, it’ll definitely benefit Smith who has been fine this series, but not significantly better than Quick. The Kings team save percentage at 5v5 on the road is at 92.96% – fifth among all of the playoff teams.
Another look at the Oilers skaters at 5v5 at home, and sorted by their on-ice goal differential (i.e., Goals +/-). As noted last time, Draisaitl and Hyman have struggled in this series at even-strength as the Oilers tend to get out-shot and out-chanced with them on the ice. So it makes some sense to have Draisaitl play with McDavid. The problem is the Oilers already allow more chances than they can generate at home. And with the Oilers loading up their top lines, there’s plenty of opportunity now for the Kings to control the flow of play and exploit the depth players.
It’s also worth noting that Ceci and Keith have also seen their numbers take a slide when playing at home, and I wouldn’t be surprised to see the Kings continue targetting Keith’s side of the ice.
Anything can happen in game seven on Saturday night, but here’s hoping the Oilers coaching staff knows what their issues at even-strength are at home and can make the necessary adjustments to improve their odds of moving on to the second round. In game six, the solution was to play McDavid more often at 5v5, as the captain was on the ice for 42% of the team’s total ice time, an increase from 33% over the previous five games. It’s fair to expect the same on Saturday, and it’ll be interesting to see how the Kings coaching staff and players respond.
Quick evaluation of how things have gone for the Edmonton Oilers in their first four games of the playoffs. Two games at home, two on the road and a 240-minute sample size, let’s dig in. This should also be much more enjoyable than the last time I did a four-game playoff review of the Edmonton Oilers.
Let’s start with the good news:
The Oilers have two wins, outscoring the Kings 17-10 in all situations, and 10-7 at even-strength (5v5), a goal-share of 58.82%.
Their overall results at even-strength (5v5) are supported by solid shot-share numbers, with the Oilers controlling the flow of play as reflected by their 53.21% Corsi For percentage and generating a higher share of scoring chances – posting an Expected Goals For percentage of 56.64%. These are fairly consistent with how they ended the regular season.
The goaltending has been solid with the Oilers posting a team save percentage of 93.63% in all situations, ranking second in the league. Among 16 goalies who have played at least 80 minutes at even-strength (5v5), Smith ranks seventh with a 93.75% save percentage and fifth with a +1.55 goals-saved-above-average (GSAA).
The Oilers powerplay continues to be excellent, converting on 35.7% of their chances and scoring at a rate of over 13 goals per hour. They’re also generating over 60 shots per hour with the man-advantage, which is right around where they were in the regular season.
The penalty kill has also been very good, killing 93.3% of the Kings opportunities, allowing only one goal and scoring a shorthanded goal as well.
With McDavid on the ice at even-strength (5v5), the Oilers have completely dominated the Kings, posting a Corsi For percentage of 65.74%, an Expected Goals For percentage of 72.40% (!) and out-scoring the opposition 5-2 (a 71.43% goal-share). These are superhuman on-ice numbers and the Kings don’t appear to have a solution for him.
The things that might be of concern to the Edmonton Oilers:
While the team is breaking even in terms of goal-differential without McDavid on the ice at even-strength (5 GF, 5 GA) there’s a concerning drop off in the team’s overall play, especially defensively, as they’re getting outshot and out-chanced without their captain.
In about two hours of total 5v5 ice time without McDavid, about 67% of the team’s total ice time, the Oilers are spending more time without the puck and are allowing just over 40 shots against per hour – 10 shots higher than league average levels. Their current Expected Goals For percentage is closer to what the Oilers were posting when Tippett was coaching.
Looking at the on-ice numbers for forwards and defencemen this series, we see that the top line players are doing great, but most of the other players, including some of the top end forwards are having some issues. The table below is sorted by on-ice goal-differential and has a basic heat map applied to see how the players compare to one another.
One tandem in particular is Draisaitl and Hyman, who are both posting Corsi For percentages around 45% and expected goal shares even worse than that. As Dennis King mentioned on my show recently, the two of them did not post very good numbers on the road together during the regular season, indicating that they may be struggling when opponents have last change and can apply specific tactics. Since the coaching change, the two played 128 minutes together on the road, going -1 in goal differential (5 GF, 6 GA) posting an on-ice Corsi For percentage of 46.71% and an Expected Goals for perentage of 42.65%.
Not sure what the coaching staff is expecting from Archibald. He was dreadful in his limited minutes during the regular season and is only dragging down Nugent-Hopkins – who himself struggled in the last twenty five games of the regular season. If the Oilers want to make a deep run, they need three solid lines that control the flow of play and out-chance opponents. It’ll be interesting to see if Woodcroft and the coaching staff recognizes this and can make the necessary adjustments. Perhaps putting Nugent-Hopkins with Puljuarvi is the answer, as we know the Finn tends to have a positive influence on his linemates, especially on the defensive side of things.
The other issue facing the Oilers is the play of Jonathan Quick whose even-strength numbers (93.40 save percentage, +0.95 GSAA) are slightly above average and only slightly below Smith’s numbers in this series. As mentioned in my series preview post, Quick posted above-average numbers in the final twenty give games of the Kings season, and was getting breaks between starts, so it wouldn’t be surprising if he finishes with numbers similar to Smith.
Joined by Dennis King (@dkingbh) to discuss the Edmonton Oilers first round series against the Los Angeles Kings, what’s gone well in the first three games, and what to keep an eye on. We also shared our thoughts on the Oilers upcoming off-season, what to do with Evander Kane and how the Oilers might handle Jesse Puljujärvi’s next contract. We also discussed the potential roster options for next season, including the prospects that could push for spots and which free agents the Oilers might be targeting.
With the first round of the playoffs set to begin, I wanted to get a sense of how both teams finished the season, what their key drivers were and how individual players performed.
The Oilers we know have been outstanding since the coaching change, going 19-4-2 in their final twenty-five games, a points percentage of 0.800 – second best in the league only behind Minnesota who went 19-3-3 in their last twenty five games. The Oilers had the highest all-situations goal-share in the league, posting a +35 goal differential due in large part to their outstanding play at even-strength, solid goaltending and excellent results on the penalty kill.
The Kings had solid results as well over their final twenty-five games, going 13-8-4, which translates into a 0.600 points percentage. And while they did a solid job out-shooting opponents at even-strength and generating an average rate of shots on the powerplay and preventing shots on the penalty kill, they only posted a -6 all-situation goal-differential – a 47.89% goal-share that ranked 18th in the league.
Here’s how the two teams performed at even-strength (5v5) over their final twenty-five games.
Last 25 games, 5v5
The two clubs are fairly evenly matched when it comes to shot-share metrics, with both teams posting a Corsi For% and Fenwick For% above 53% – right around what top teams typically post. The Kings have been doing it a lot longer this season, as we know the Oiler’s process metrics, especially their share of quality scoring chances, only improved after the coaching change. Regardless, what’s apparent is the big difference in scoring talent, as the Oilers finished with the 11th best team shooting percentage in the league at even-strength while the Kings were dead last. Full details on how the Oilers and Kings rank within the western conference can be found here.A summary table can also be found in the Appendix at the end of the article..
The Oilers also got great goaltending at the end of the season, with Mike Smith posting some of his best numbers in his career and posting a save percentage above 94%. Below are the Oilers and Kings goalies from the last twenty-five games, with their rankings among the 61 goaltenders who played at least 250 minutes.
Worth noting that while he wasn’t playing at the level of Smith, Jonathan Quick was still above league average levels in the last stretch of the season posting a goals-saved above average (GSAA) of +5.48 (19th among 61 goalies) and a high-danger save percentage of 0.849 (17th). Both Koskinen and Pedersen ranked fairly poorly, which will make it an interesting series if one of the starting goalies struggle.
The Edmonton Oilers powerplay had a strong finish to the season, generating the highest rate of shots per hour (70.38) in the league over the final twenty-five games, and scoring over 10 goals per hour – ranking 6th best overall. These numbers were consistent with their full-season results on the powerplay, largely driven by their top end players and their overall tactics.
And while the Kings generated the fourth highest rate of shots on the powerplay in their final twenty-five games, they were again let down by their shooting talent, as they could only muster 5.34 goals per hour – ranking 25th in the league. These results were also consistent with their full-season results.
Powerplay (Last 25 games)
The Kings did pretty well on the penalty kill, allowing 7.82 goals against per hour (16th in the league) due in large part to their play in front of their goalies. They allowed the 10th lowest rate of shots against in the league, and got league average goaltending.
The Oilers penalty kill on the other hand relied completely on their goaltending, as they allowed the fourth highest rate of shots against in the league, but got the best team save percentage (93.53%). I’m a little skeptical that the Oilers goaltenders will be able to maintain this level considering their full-season save percentage was 87.53% – which ranked 10th in the league. The Kings could find an edge here considering they have consistently generated chances on the powerplay, something the Oilers need to be mindful of.
Penalty Kill (Last 25 games)
Another thing I wanted to see ahead of the series was how the players on each team did in terms of on-ice shot and goal differentials at even-strength (5v5) over the final twenty-five games. Just to get a sense of which players are playing well, but might not be getting the results.
Below are all of the Oilers skaters, sorted by their on-ice goal differential (Goals +/-), with the Oilers top line players leading the way.
Puljujärvi, McDavid and Kane had excellent results at 5v5 to finish the season, with all three posting solid shot differentials. McDavid is a major driver for results, but it’s worth noting that even when away from McDavid, Puljujärvi is posting strong numbers. Over this final stretch of games, Puljujärvi has played 111 minutes away from McDavid (about 40% of his total ice time), and posted an on-ice expected goal-share of 64%, and an on-ice goal-share of 70% (7 GF, 3 GA). For comparison, Kane has played 63 minutes away from McDavid (about 15% of his total ice time), and posted an on-ice expected goal-share of 41% and on-ice goal-share of 60% (3 GF, 2 GA). It’s clear Kane needs McDavid to thrive, while Puljujärvi seems to post solid numbers offensively and defensively, wherever he is in the line-up. That’s an important player to have come playoff time when line matching and finding any sort of edge becomes critical.
One player that will need to improve for the playoffs is Nugent-Hopkins, who posted poor shot-differentials over the last twenty-five games. He’s not getting the tough match-ups, so I’m suspecting either there’s an injury issue he’s dealing with or he’s struggling with not having consistent linemates. Regardless, he and others including Hyman and Draisaitl will have increased roles in the playoffs so hopefully whatever ails them can be fixed by the coaching staff.
Looking at the Kings skaters, only Athanasiou was riding percentages to close the year. The key player to watch is Arthur Kaliyev who posted excellent on-ice shot and expected goal differentials, but couldn’t convert those into actual goals. Both Kopitar and Danault are worth watching closely, as they’ll likely see a lot of the top lines. Plus they can hold their own and challenge for offence as well. The Kings do have some good supporting talent including Kempe who scored 35 goals this season and Arvidsson who has a history of scoring – so we’ll see if they can turn things around in the playoffs. And while they’ve been without Doughty who helps more offensively, the Kings have been fine over the last twenty-five games allowing the fifth lowest rate of shots against at even-strength in the league and the 10th lowest rate of expected goals against. The Oilers were closer to league average defensively. For a deeper dive into the Kings line combinations, check out Sid’s work here.
The Oilers have the edge when it comes to talent up front, and their goaltending was much better at the end of the season. But the Kings have been pretty solid as well posting similar shot-share numbers as the Oilers, and playing very well defensively both at even-strenth and the penalty kill. And while their goaltending hasn’t been great, Quick has been performed slightly above average over the Kings last twenty-five games. So it shouldn’t surprise anyone if he steals a game or two. If the Kings can pressure the Oilers defence, which could still potentially be exploited, and capitalize on their chances, this might be a longer series than some might anticipate.

Points-percentage (Point%) – The total points accumulated divided by the points that were available, including extra time.
Corsi For percentage (CF%) – The proportion of all the shot attempts the team generated and allowed that the team generated (i.e., Corsi For/(Corsi For + Corsi Against). This is used as a proxy for possession and is the best at predicting a team’s future share of goals (GF%). (Source: Hockey Great Tapes – Draglikepull)
Fenwick For percentage (FF%) – The proportion of all the unblocked shot attempts the team generated and allowed that the team generated (i.e., Fenwick For/(Fenwick For + Fenwick Against). This is used as a proxy for shot quality and considers shot blocking a repeatable skill.
Expected Goals For percentage (xGF%) – This is a weighting placed on every unblocked shot based on the probability of the shot becoming a goal. This depends on the type of shot, location and uses historical shot and goals data to come up with the probability for each unblocked shot.
Goals For percentage (GF%) – The proportion of all the goals that the team scored and allowed that the team generated (i.e., Goals For/(Goals For + Goals Against).
Shooting percentage (SH%) – The percentage of the team’s shots on goal that became goals (i.e., total goals divided by the total shots on goal).
Save percentage (SV%) – The percentage of the team’s shots on goal against that were saved (i.e., 1-(totals goals allowed divided by the total shots on goal against)
