CBC Radio Active: Oilers trade deadline activities

I joined Jessica Ng on CBC Radio Active to talk Oilers and the deals they made at the NHL trade deadline. Full segment is here: CBC Radio Active (2023, March 3).

Topics we covered:

  • The acquisition of Mattias Ekholm and Nick Bjugstad, and the key elements that they’ll bring to the roster.
  • Ken Holland’s overall approach with the trade deadline.
  • Fan reaction to the trade deadline and the overall outlook of the Oilers heading towards the playoffs.

Thanks as always to the team at CBC for putting it all together.

Tracking the Western conference – As of February 28, 2023

The Edmonton Oilers are in a good spot right now in the western conference, holding on to the first wild card spot and only a few points outside of first in the Pacific division. They have the best overall goal differential in their division (+31), which ranks eighth highest in the league.

Below is a summary of the western conference, sorted by each team’s points percentage. Included in the table is each team’s even-strength performance numbers (i.e., shot-share metrics that measure how well a team controls the flow of play and the total chances) as well as each team’s goal-share and goal-differential. I’ve also included each team’s shooting percentage and save percentage to get a sense of what might be driving their overall results. And I’ve applied a simple heat map to each metric to show how each club compares to the rest of the conference.

It’s been the last 25 games of the season that the Oilers have really separated themselves from the rest of the western conference. In this stretch, which is from December 31, 2022 onwards, the Oilers rank top five in the league when it comes to generating shots and scoring chances at even-strength, and top five when it comes to preventing shots and scoring chances. This is even before acquiring Mattias Ekholm, who is only going to further improve things and be a massive boost for a playoff run.

The western conference is going to be wide open, and it appears the Oilers (at least for now) should be the front-runner for a deep playoff run if they can continue dominating at even-strength.

Across the NHL, powerplays are powering up

Goal scoring is up this season. And powerplays appear to be a major factor. A look into the key drivers, the growing importance of powerplays, and how this could impact the Edmonton Oilers.

When I was digging into the Oilers special teams numbers recently, I found that there’s been a real increase in the rate of powerplay scoring across the league. Goal-scoring overall (all-situations) has been increasing over the last few seasons thanks to an influx of talent in the league, with more and more players becoming point-a-game producers. And powerplays appear to be one of the driving factors.

First we have to keep in mind that powerplay opportunities this season are up slightly. In the last six regular seasons (2017/18 to 2021/22), teams on average received about 2.84 powerplay opportunities per game. This season, it’s up to 3.15. (Source: Hockey Reference).

So far in the 2022/23 season, teams on average are scoring at a rate of 7.84 goals per hour on the powerplay, which would translate to about 55 goals over a full 82-game season. This rate of goal-scoring is an increase of 10.2% compared to the goal-scoring over the previous six seasons (7.12) when teams would score around 49 powerplay goals on average (over an 82-game season). The upward trend appears to have started in 2021/22 – the first real 82-game season following two pandemic-shortened seasons that had limited games, limited fans and limited gate revenue.

What’s interesting is that it’s not necessarily just the finishing ability that’s driven the powerplay success. Shooters as a collective are getting better, currently converting 13.9% of their powerplay shots into goals this season, an increase from the 13.4% players had posted on average over the previous six seasons (an increase of 4.2%).

But the bigger factor in the growth of powerplay scoring has been the increased rate of unblocked shot attempts (i.e., Fenwick, a proxy for scoring chances) and shots on goal – things that are driven not only by the talent on the ice but the tactics implemented by the coaching staff.

This season, teams are averaging 78.66 unblocked shot attempts per hour on the powerplay, an increase of 7.0% compared to the previous six seasons. And the rate of actual shots on goal is up by 5.9%, sitting at 56.26 per hour so far this season (refer to Appendix A for a summary table). Again, the upward trend in generating chances and shots appears to have started last season – and I think we can expect it to continue to climb because of the talent in the league, and with teams recognizing the importance of powerplay scoring.

This season, 1,179 powerplay goals have been scored in the league, which is 21.8% of the total goals scored (i.e., all-situations). This is a 7.8% increase over the previous six seasons when powerplay goals made up 20.3% of the total goals. So that’s about 85 more powerplay goals than expected. Should note, the proportion of even-strength (5v5) goals is actually down compared to previous seasons – sitting around 64.9% of total goals this season compared to 66.9% over the last six seasons (refer to Appendix B for a summary table).

From an Oilers perspective, I think the key takeaway here is that the competitive edge that their powerplay currently provides is eventually going to be reduced as more and more teams get better on their powerplays. I think teams, and especially owners, want to be more competitive not only to win games, but to also re-coup their financial losses caused by the pandemic and other factors. And to do that, it’d probably be in their best interest to use the growing talent pool to push for more goals – especially on the powerplay – and more wins in the standings.

In response to the increased offence generated by powerplays, which will likely continue increasing, it may be in the Oilers best interest to find new solutions for the penalty kill. As I wrote about recently, the Oilers penalty kill started off very poorly this season but has improved as they’ve adjusted their deployment, reduced the rate of shots and chances against and received better goaltending. But it might be time to bring in more expertise at the coaching level and player level to ensure that the penalty kill doesn’t cost the team any more wins, like it did earlier this season.

Put another way, the Oilers penalty kill has to become one of their competitive edges if they want to have success.

Upswing

The last time I looked at the Oilers penalty kill, it was twenty-five games into the season, and the situation was pretty dire. They  were having all sorts of issues defensively, allowing some of the highest rates of shots and scoring chances against, resulting in the fourth highest rate of goals against in the league. What was especially troubling was that the penalty kill was basically giving back all of the goals that the Oilers powerplay had generated. Despite having the best powerplay in the league, the special teams as a whole gave the team nothing.

Since that point, and after I published my article (!), things appear to have turned around for the Oilers penalty kill.

When it comes to the team’s penalty kill performance, the Oilers have gradually improved at limiting unblocked shot attempts (a proxy for scoring chances) and shots on goal. In the first twenty-five games, they were allowing the ninth highest rate of unblocked shot attempts (82.98) and the sixth highest rate of shots against (61.69). In the most recent twenty five game stretch, they’ve seen their rate of unblocked shot attempts drop by 15.5% to 70.13 (tenth lowest in the league) and their rate of shots against drop by 17.6% to 50.81.

This improved performance has translated into better results, as the Oilers have allowed a significantly lower rate of goals against. In the first twenty five games of the season the Oilers allowed 26 cumulative goals (3 GF. 29 GA) – a rate of 12.60 goals against per hour, which was fourth highest in the league. In the most recent stretch of twenty five games, the Oilers have allowed 10 cumulative goals (5 GF, 15 GA) – a rate of 6.30 goals against, which ranks 13th in the league. They’ve basically cut their goals against in half.

The other factor to consider is the team’s goaltending on the penalty kill, which has also improved. After the first 25 games, the Oilers team save percentage ranked 29th in the league with 78.90%. Among 42 goalies who had played at least 45 minutes on the penalty kill, Campbell ranked 39th with a 78.90% save percentage and a -4.73 goals saved above average. Skinner wasn’t faring much better at the time, as he ranked 36th in the same pool of goalies with a 80.30% save percentage and 37th when it came to goals saved above average with -3.21.

Thankfully both netminders have improved over the course of the season, especially Campbell. Over the last twenty five games, the team save percentage has ranked 15th in the league, with 87.60%. Campbell’s save percentage of 89.50% ranks 13th among 42 goalies who have played at least 45 minutes on the penalty kill. Skinner’s numbers, while still modest, are an improvement as well and rank closer to league average levels.

The coaching staff clearly made the penalty kill a priority and made tactical adjustments, which has helped drive their overall results and kept them competitive in a tight playoff race. At the twenty-five game mark this season, the Oilers special teams had a net goal differential of -1. Since then the powerplay has continued to excel, and so to has the penalty kill, which has helped the special teams differential improve to +17. That’s worth about three wins in the standings, or six points. Had the penalty kill performance and results stayed the same as it did earlier in the season, the Oilers would likely be outside of a playoff spot.

It’ll be interesting to see how this could impact the Oilers approach at the upcoming trade deadline. There’s been plenty of speculation about management targeting defencemen, especially those that can help the Oilers in their own zone and potentially on the penalty kill. Names like Joel Edmundson and Vladislav Gavrikov were floated, among others, when the Oilers were struggling. And now that the team has gradually improved, we’re hearing the names of more offensive-style defencemen like Erik Karlsson landing in Edmonton. Could go either way at the trade deadline with this management group.

One other observation. The Oilers penalty kill percentage, the way the NHL tracks penalty kill success, currently ranks 19th in the league. But when you look at the rate of goals against per hour on the penalty kill, which factors in how much time it takes to score against the penalty kill (which is in my opinion the better metric to evaluate a penalty kill’s success), the Oilers rank 26th. I think what that tells us is that while the Oilers are okay at killing penalties, when they do allow a goal, it happens early on in their penalty kill. Which is when the first penalty kill unit is on the ice. Might be worth looking into how the first unit compares with the second unit, and how they compare league-wide.

Tracking the Western conference – As of January 31, 2023

Since the Oilers are going to be in a competitive playoff race following the all-star break, I’m switching over from a monthly division review to a western conference review. The Oilers are currently sitting in fourth place in the Pacific with 60 points, trailing Seattle, Vegas and Los Angeles. And they’re holding on to the first wild card spot in the west, three points ahead of Colorado. The Oilers have made significant progress recently, which has helped them get out of the hole they had themselves in earlier in the season.

Below is a summary of the western conference, sorted by each team’s points percentage. Included in the table is each team’s even-strength performance numbers (i.e., shot-share metrics that measure how well a team controls the flow of play and the total chances) as well as each team’s goal-share and goal-differential. I’ve also included each team’s shooting percentage and save percentage to get a sense of what might be driving their overall results. And I’ve applied a simple heat map to each metric to show how each club compares to the rest of the conference.

The Oilers currently have the third best points percentage in their division and sixth highest in the conference. Based on how well they’ve been performing since mid/late November, they should be able to maintain their position and compete for a top-three finish in their division. They’ve had a fairly healthy roster, and their goaltending has been steady – both are going to be factors over the last thirty-two games of the season.

From an Edmonton perspective, there’s a few teams to keep an eye on.

Calgary, whose points percentage ranks ninth in the west and fifth in the Pacific, continues to perform well at even-strength, controlling the flow of play, out-shooting and out-chancing opponents. But because of some pretty shoddy goaltending, which ranks 27th in the league, and a forward group that has struggled to score, they’re tied in points with Colorado for the second wild card spot in the west.  The other issue, as we’ll see below, is their powerplay which ranks 25th in the league in terms of goals per hour.

Los Angeles is the other interesting club. They’re performing well at even-strength, but appear to have the same issues they’ve had in the past, which is converting their chances into actual goals. Their goaltending has been poor as well, which has to be frustrating considering the Kings (similar to Calgary) are one of the best teams in the league at suppressing shots and scoring chances.

The rest of the western conference isn’t very impressive. Dallas is the one club that looks legit. Colorado is getting healthy again up front, so their shooting percentage and overall results should gradually improve. Vegas is dealing with injury issues now and are having trouble outscoring opponents. Winnipeg is going to be relying on it’s goaltending to have any success. Seattle is doing well, but they can be brought down by the own goaltending and special teams. Even Minnesota who was having success earlier in the year has come back down to earth, and is having trouble scoring goals. Will be interesting to see if any of these clubs can separate themselves from the rest of the group, similar to what some of the top end teams in the east have already done.

With the western conference feeling so wide open, and the success the Oilers have had in their last month or so, I think the club should have some confidence in their ability to move up in the standings and have some success in the playoffs. The trade deadline and the gossip around the Oilers will give us an indication of what management’s confidence level is like.

For additional context, I’ve also put together a quick summary of each team’s powerplay and penalty kill numbers. Sorted by each team’s points percentage again, I’ve included the rate of unblocked shot attempts (i.e., Fenwick for, FF/60) on the powerplay as well as the actual rate of goals per hour (GF/60). And the rate of unblocked shot attempts and goals against on the penalty kill. Again, I’ve applied a simple heat map to each metric to see how each club compares in the conference.

Lastly, below is how each team has performed at 5v5 over their last twenty five games heading into the all-star break. We know Edmonton has done well in terms of shot-share numbers, but so has Dallas, Colorado, Calgary and San Jose. Vegas looks like they’re slipping, and while teams like St. Louis are fading out of the playoff race quickly.

Oilers player deployment and on-ice numbers over the course of the season

Couple other items I’ve been tracking is how players are being deployed over the course of the season and what their on-ice performance numbers have been like at even-strength (5v5). Reason being, the Oilers had a fairly poor start to the season, so it’ll be good to know which players have been part of the turnaround and which ones have been less influential.

Quick summary below, separating out forwards from defencemen, comparing games 1-25 with games 26-50. Tables are sorted by average time on ice (TOI/GP) and include each players on-ice Corsi For percentage (CF%) – i.e., the team’s share of shot attempts, for and against, which serves as a proxy for a team’s puck possession capabilities. I’ve also included the changes in average ice time per game and Corsi For percentage, and applied a simple heat map to show how players are doing relative to their teammates.

As I wrote about in my last post, the Oilers on-ice performance numbers have significantly improved over the course of the season with most players seeing a bump in their on-ice Corsi For percentages. Couple players stand out when doing this exercise including Mattias Janmark who continues to post poor on-ice shot-share numbers even when the team as a whole is improving. And Klim Kostin who is the only player whose on-ice numbers declined in the last twenty five games. I’m not sure these two are quite ready for tougher minutes, and are likely better suited as depth, replacement-level options.

On the flip side, Puljujarvi has seen his ice-time gradually diminish. But as he plays more and more against lesser competition, his on-ice numbers have seen a nice bump. Not sure if they’re letting him play more of his game and less concerned with how many hits he throws when in the top six. But it’s clear he should be playing higher up in the rotation. Holloway is the other bright spot among the forwards – he should be playing more regularly with the high end forwards. The team needs to know what they have in this player as soon as possible to start planning out their roster decisions for next season and beyond.

On the back end, we know Broberg has been gradually improving, and he has some nice on-ice numbers over the last twenty five games. It’s important to note though that his minutes have been against lesser competition, with a lot of on-the-fly shifts when the play is going towards the opponents end, so we’ll have to temper our expectations. Similar to Holloway, the Oilers need to determine what Broberg’s ceiling is as soon as possible to start making big-picture roster decisions. If the coaching staff and management is confident he can be a top four defencemen starting this year, great. But if there’s some hesitation, they have to cut ties before other teams figure it out. Being a high draft pick will be appealing, and if you can upgrade him to a defencemen who can help the team win in the next couple years you have to consider it. For now, he’s a great story and showing improvements in his game. Let’s see if the coaching staff thinks he’s ready for tougher assignments.

Speaking of assignments, below is a quick snapshot of how the Oilers coaching staff has been deploying their defencemen, comparing the first twenty give games of the season, to the most recent twenty five games (Source: Puck IQ).

Games 1-25 (up until December 4, 2022)

Games 26-50 (after December 4, 2022)

Nurse and Ceci were regularly getting the bulk of the tougher minutes earlier this season, but the coaching staff has scaled them back slightly which has benefited them and the team. Kulak, who struggled early on in the season, appears to be back in form and has seen a slightly higher share of the tougher defensive assignments. The rest of the roster, including Broberg and Desharnais, continue to play against lesser competition, which is understandable considering their lack of experience and the urgency to win games.

Thanks as always to the team at CBC for putting it all together.

Night and day

The Oilers are posting some excellent results as of late, coming at a critical time where they’re trying to recover from their poor results early on in the season and now holding on to a playoff spot. After 50 games, the Oilers rank fourth in the Pacific division with 60 points (third with a 0.600 points percentage), and holding on to the first wild card spot in the western conference.

It’s really been at even-strength (5v5) where they’ve turned things around, as they’ve gone from a 47% goals for percentage at the Christmas break (a -8 goal differential, after 35 games) to the 52% goal share they have now (a +8 goal differential, after 50 games). Digging through the underlying performance numbers (i.e. shot-share numbers) which help drive results, it’s become evident that the Oilers have gradually been improving for a while now, well before their loss to the Los Angeles on January 9th (game 42) at home, after which the Oilers won seven of their next eight.

To get a sense of their performance numbers this season, below is the team’s Corsi For percentage over 25-game rolling segments. Early on in the season, the Oilers were having issues controlling the flow of play, spending more time without the puck and posting a Corsi For percentage of 49.2% at the Christmas break (first 35 games of the season), which ranked 19th in the league. And it was part of the reason why at that point they only posted a 47% goal-share (a -8 goal differential) and were struggling to hold on to a wild card spot in the west.

The club’s performance gradually improved with the team posting a 54.68% Corsi For percentage in their last 25 games, which ranks 4th highest in the league and closer to what the Oilers posted under Woodcroft last season. There’s likely been some tactical changes, but it’s also been driven by some key players performing much, much better – especially on the defensive side of things.

It’s hard to pin down exactly when the Oilers decided to change their overall approach. But if I had to guess, it was after their 5-2 loss in New Jersey on November 21st, the 19th game of the season. The Devils dominated the Oilers, controlling 60% of the shot attempts and scoring chances, outscoring the Oilers 4-1 at even-strength – a pretty embarrassing beat down. Perhaps it was seeing first-hand how one of the top teams in the league finds success. Or maybe the fact that after the game, the Oilers were 18th in the league in terms of points percentage that gave them a wake-up call. At that point, they had allowed the sixth highest rate of shots against at even-strength in the league, the third highest rate of scoring chances and the seventh highest rate of goals against. After that game and up until the Christmas break (between games 20 and 35), the Oilers posted a 53% Corsi For percentage, but only a +2 goal differential at even-strength.

Now for simplicity and to see how the Oilers improved over the course of the season, I’ve split the season into two segments – games 1-25 and games 26-50. In the table below, I’ve listed out their various performance metrics (i.e., shot-attempts, expected goals) to get a sense of how well the Oilers controlled the flow of play and scoring chances. I’ve also included the actual results – record, points percentage and goal-share.

Oilers (5v5) First 25 Second 25 Percent Change
Record 14-11-0 14-7-4  
Point % 0.560 0.640 14.3%
CF/60 54.43 61.36 12.7%
CA/60 58.24 50.85 -12.7%
CF% 48.31 54.68 13.2%
SF/60 29.03 34.33 18.3%
SA/60 32.42 27.78 -14.3%
SF% 47.24 55.27 17.0%
xGF/60 2.65 3.11 17.4%
xGA/60 2.85 2.38 -16.5%
xGF% 48.24 56.59 17.3%
GF/60 2.35 3.12 32.8%
GA/60 2.81 2.28 -18.9%
GF% 45.54 57.80 26.9%
SH% 8.05 9.23  
SV% 91.30 91.87  
PDO 0.994 1.011  

The Oilers have made a significant recovery from earlier in the season, at one point posting a 43% goal-share in late November, and have moved up in the standings. The big reason for their success is the improved defensive play as the team has allowed 12.7% fewer shot attempts per hour and 16.5% fewer expected goals per hour compared to the first twenty five games. The rate of shots against in the last 25 games (27.78 per hour) is the eighth lowest in the league – a major improvement from when they were allowing the sixth highest rate in the league after the first 25 games of the season. The team’s performance over the last twenty-five games does indicate that the actual results are sustainable, as long as the roster can maintain league average shooting and save percentages. Barring any injuries to key players, it’s safe to assume that the player-driven metrics will be around the same range they’ve been at for the rest of the season.

Couple other things to note.

The Oilers are currently performing really well without their two star players, who the coaching staff is playing together a lot more now compared to the first half of the season (and significantly more than last season after Woodcroft took over). In the first 25 games, the duo played 142 minutes together, or approximately 12% of the team’s total even-strength time. In the last 25 games, that’s moved up to 18% (199 minutes) of the team’s total even-strength time. Without the duo, the Oilers have performed well over the year, controlling 52.09% of the shot attempts, and out-scoring opponents 42-36 (a 53.85% goal share). Suspect a big reason why the coaching staff has played their two stars together more often is because of Draisaitl’s struggles at even-strength this season, especially on the defensive side of things. His on-ice shot-share numbers were one of the worst on the team early on in the year, but that’s significantly improved in the last 25 games. Instead of allowing over 35 shots against per hour with Draisaitl on the ice, the Oilers are now allowing just under 30, and much closer to league average levels. It’s unfortunate that Draisaitl can’t be deployed regularly on another line to help spread the offence, but the Oilers are doing fine without the two stars, probably giving the coaching staff some comfort.

I’d be curious to know from the coaching staff about the tactical and deployment changes and what they think the key drivers have been. As mentioned above, the team did start to turn things around much earlier than the Christmas break as they were posting solid shot share numbers between late November and late December, so I’m not convinced that the Christmas break is when changes were implemented. And as great as the success has been, you have to question why it took so long for the team to figure things out. Better late than never, but the Oilers have had to go on quite the run just to hang on to a wildcard spot in the west – something that could have been avoided had the team, and some key players, not played so poorly defensively. Fortunately with the Pacific division being as weak as it is, the Oilers are in a better spot now compared to a month ago.
