What’s going on with Leon?

The star forward is among the league leaders in points, but his production and on-ice numbers at even-strength are lower that expected. It’s critical for the coaching staff and management to figure out what’s going on with Draisaitl if they want their 5v5 numbers to improve.

There’s obviously a lot of team-wide issues right now for the Edmonton Oilers, as the club ranks fifth in the Pacific with a 0.526 points percentage and ninth in the western conference. Defensive play has been poor, the offence has dried up, and there’s plenty of questions about the roster construction and the potential internal solutions. It’ll be interesting to see how the coaching staff and management navigate things in such a high pressure season.

Even-strength (5v5) play is the biggest point of weakness for the club as they’re getting out-shot, out-chanced and out-scored regularly – ranking in the bottom third of the league when it comes to performance indicators that drive positive results. And it’ll need to improve if the Oilers want to keep up with the top teams in the league.

One player in particular that is currently struggling playing even-strength minutes is Leon Draisaitl. He’s a proven star in the league and can improve the team’s odds of winning games. And he’s among the league leader in points this season because of his dominance on the powerplay. But his even-strength numbers this season, including his personal numbers and his on-ice numbers, have been poor compared to his previous three seasons – and it’s part of the reason why the Oilers are struggling to win games.

Starting with his personal numbers, Draisaitl currently has nine even-strength points which ranks fourth on the Oilers – a points per hour rate of 1.85. That’s a drop from the 2.68 points per hour from his previous three seasons – a level that top line, star forwards typically produce at. Heading into this current season, Draisaitl’s rate of points ranked 17th among over 500 forwards who played at least 1,000 minutes since 2019, a period in which he’s accumulated the third highest number of points in the league. His current rate of 1.85 ranks 131st among 324 players who have played at least 200 minutes this year – not anywhere near where he should be considering his history.

What’s driving his drop in production is his individual rate of shots per hour which has decreased from 6.43 per hour over the last three seasons to 5.56. And his shooting percentage is also lower than expected, currently sitting at 14.81%. Considering his age and his talent, you would expect to see his rate of shots and his shooting percentage to gradually improve, resulting in better productivity over the course of the season. But there’s a couple other issues to consider.

One reason for his lower rate of shots per hour this season is the fact that the Oilers are spending a significant amount of time without the puck when he’s on the ice, as reflected by the team’s Corsi For percentage (a proxy for puck possession) of 42.83%. The team is also getting out-chanced more regularly when Draisaitl is on the ice with, as reflected by their 43.19% share of expected goals (a proxy for scoring chances and shot quality) – which again is a drop from the levels we’ve seen with him on the ice over the last three seasons. All of Draisaitl’s on-ice shot-share numbers (i.e., Corsi For%, Fenwick For%, Expected Goals For%) are some of the lowest on the team, only ahead of Holloway and Shore. And it’s on the defensive side of things where the Oilers are really struggling with Draisaitl, as they see more than a 17% increase in the rate of shot attempts, unblocked shot attempts and shots on goal against with their star forward on the ice. The rate of expected goals against this season – which factors in shot quality and scoring chances against – increases by 26% with Draisaitl on the ice, going from 2.78 per hour to 3.51.

Draisaitl’s poor on ice numbers at even-strength is pretty significant considering the expectations on him as a player and the team this season. The Oilers top six is supposed to be one of the best in the league, but it’s hard to accomplish anything when a star forward is struggling and the team is failing to control the flow of play and total scoring chances with him on the ice.

What’s worth noting is that Draisaitl is struggling with pretty much every linemate and defenceman on the Oilers, unable to post shot-share numbers like Corsi For% and Expected Goals For% above the 50% break-even mark, regardless of the player he’s with.

The one player that Draisaitl is having success with this season is Bouchard, as they’ve played 90 minutes together and posted a Corsi For percentage of 51.71% and an Expected Goals For percentage of 52.26 – both numbers being well above the team’s current averages. With Nurse having his own issues and posting some of his worst on-ice numbers in his career this season, it might be beneficial to the team, and especially for Draisaitl, if Bouchard saw an increase in his even-strength minutes and more time with the top lines.

Whatever the coaching staff and management decide to do to improve the team, whether it’s internal or external solutions, it’s important to have a firm grasp of the real issues plaguing the team and implementing changes that help improve the odds of winning games. Considering their poor results and underlying numbers at even-strength – where 80% of the game is played – it’s critical they focus here first and find tactical and deployment solutions as soon as possible.

Issue detection

Really can’t emphasize enough how much of a drop off there’s been when comparing this season’s results to last season after the coaching change occurred. One of the biggest improvements the Edmonton Oilers made after Jay Woodcroft took over in February 2022 – and what helped drive the overall results – was the team’s possession and scoring chance numbers at even-strength as the club went from around league-average levels to being one of the best in the league.

After the coaching change last season, the Oilers played more aggressively with leads, they spread out their offence across multiple lines and their depth players weren’t getting out-shot and out-chanced as much as they had been in previous seasons. All of these coaching-driven factors played a major role in the overall results at the end of the 2021/22 regular season, and the process behind it all was based on sound logic and reasoning.

Fast forward to this season, and the team isn’t anywhere near where they were in the final thirty-eight games of last season. Their possession numbers and share of scoring chances are currently some of the lowest in the league, with their Corsi For percentage dropping down from 53.71% last season to 47.76% this season. And their share of expected goals is down to 46.29% – which ranks 26th in the league only ahead of Anaheim in the Pacific division.

Now it’s understandable if the Oilers defensive play gets most of the attention as the results are what stands out first. They’re currently allowing the seventh highest rate of goals against at even-strength (2.78), and their penalty kill is allowing 12.04 goals against per hour – the third highest in the league. Management didn’t exactly build a strong, championship caliber defence core either and we’ve seen established players struggle throughout this season and some of the young prospects struggle to gain traction at the NHL level. The team also spent a lot of money on a new starting goalie who is struggling early on this season – which was also somewhat expected.

When we dig into the actual results, we see that they’re somewhat expected as the club is having all sorts of issues preventing shots and scoring chances at even-strength, with their rates all having increased by a significant margin compared to last season. For instance, the rate of expected goals against – which factors in shot quality and the probability of an unblocked shot becoming a goal – has increased by 17.4% this season. The table below shows the other defensive numbers from this season and the thirty eight games under Woodcroft from last season with percentage changes.

What’s further troubling are the issues up front.

With arguably one of the best top-six forward groups in the league, and with the powerplay having a lot of success and McDavid and Draisaitl leading the league in points – it can generally be assumed that the Oilers offence is and will be just fine. But if we take a look at the numbers at even-strength, that’s really not the case. And things have taken a significant hit compared to last season, similar to the levels experienced on the defensive side of things.

The Oilers are only scoring 2.26 goals per hour at even-strength, which ranks 24th in the league and last in the Pacific division. The biggest issue is that they generate some of the lowest rates of shot attempts, shots on goal and scoring chances – all of which have dropped over 10% compared to last season. The Oilers current offensive rates have them in the bottom third in the league for each category – a big drop off from the end of last season where they were closer to the top five in the league after Woodcroft took over.

You’d hope someone in the Oilers management group is aware of this situation and is questioning (a) how the roster was built the way it was, and (b) the coaching tactics and player deployment that is being implemented. There’s a significant problem in Edmonton both offensively and defensively, and it’s critical for the team to get things on track if they want to be considered a championship contender.

Bringing it home

When talking about the Oilers struggles this season at his media availability this afternoon, Woodcroft commented about the success the Oilers have had on the road this season and wanting to make their home arena a tougher place to play in for opponents.

The good news is that we’ve demonstrated a competitiveness, a will to win, a finding a way to win. Our level of simplicity and effectiveness on the road where we’re 5-2, we got to bring that home. And we got to figure out a way to make this the toughest arena in the National Hockey League to come into. We’ve done that in the past, we got to do it again. And I think that comes down to a level of consistency and building a level of consistency in your game. (Source)

Had to take a look at the data to see what exactly the difference was between the Oilers performance at home versus on the road, expecting to see some differences. But that’s not exactly what the data shows.

2022/23 Record Points% Goals For/Goals Against
Home 4-5-0 0.444 34-34
Road 5-2-0 0.714 25-24

While the Oilers have had more success on the road so far this season, there’s not much that you can take away and build off of or want to replicate at home. Their overall goal differential is only marginally better on the road, and it’s it’s worth noting that their underlying numbers at even-strength (5v5) inidicate that their results are unsustainable.

Oilers – 2022/23 (5v5) Home Road
Corsi For% 48.87 45.18
Fenwick For% 47.56 45.11
Expected Goals For% 48.61 43.18
Goals for/against 17-21 12-14
Goals for% 44.74 46.15
Shooting% 7.23 8.62
Save% 90.65 92.81
PDO 0.979 1.014

The Oilers are currently one of the worst teams on the road when it comes to controlling the flow of play and total scoring chances as reflected by their 45% Corsi For percentage and Fenwick For percentage. They have a -2 goal differential at even-strength as well, which again is only slightly better than their -4 goal differential at home.

The real reason they’re having success on the road is their goaltending, which is posting a 92.81% save percentage. Reason for that is Skinner who has played four of the Oilers seven road games while Campbell, who has struggled so far this season, has played seven of the nine home games. So if there’s anything the Oilers can take away from their road success, it’s that they should play Skinner more often at home.

Other than that, the Oilers don’t have any real strengths on the road. I’d be curious to hear Woodcroft elaborate on his comments and see if there’s anything tangible he’d like his team to improve on.

Impact statement

Sixteen games into the 2022/23 season and the Oilers haven’t established a whole lot. They have some points in the banks, have had some big wins, namely two on the road in Tampa and Florida. And their two superstars are leading the league in points. But the team hasn’t rounded themselves into proper form or made any sort of statement that they’re contending for a title.

So far at even-strength (5v5), they have a -6 goal differential, a goal-share of 45.31% that ranks 24th in the league and only ahead of Anaheim and San Jose in the Pacific division. The big issue right now is that they spend more time without the puck as reflected by their 47.32% Corsi For percentage, that ranks 24th in the league. And they allow the fifth highest rate of shots and scoring chances against leaguewide – currently giving up 47 unblocked shot attempts (i.e., Fenwick) per hour and allowing 34 shots on goal against per hour. Important to note that the Oilers are getting league-average goaltending at even-strength with their team save percentage of 91.61% ranking 16th in the league. And the team is posting a shooting percentage also around league average (7.78%). The struggles appear to be a system and deployment issue, something the coaching staff has a strong influence on, so the focus for now really should be there.

Below is a summary of the Oiler’s numbers ar even-strength (5v5), with the shot-share metrics being score and venue adjusted according to Natural Stat Trick’s method. I’ve also included the Oiler’s even-strength numbers from the 38 regular season games from last season that Woodcroft coached. That’s really the baseline that the Oilers should be working towards as we know the team is capable of playing at that level for an extended period of time.

SeasonGPPoint %CF%FF%xGF%Goal diff.GF%SH%SV%PDO
2021/22380.72453.7153.2953.25+2056.028.7891.981.008
2022/23160.56347.3246.5346.45-645.317.7891.610.994

Comparing the two periods, there’s been a pretty clear drop-off from last season, something we saw as early as five games into this season. We know the coaching staff is capable of applying some basic principles and getting stronger underlying shot-share metrics than they have right now – and improving the team’s odds of winning games. But it remains to be seen if the coaching staff can revert back to some of their tactics that gave them so much success at the end of last season.

One tactic in particular is their aggressiveness at even-strength when protecting a lead. While most teams tend to play more conservatively with a lead – more often dumping the puck rather than making a play to create a scoring chance – the Oilers appeared to be bucking that trend last season under Woodcroft when they would continue to generate offence as a way to protect a lead.

When team’s are leading in a game, they on average post a Corsi For% around 45% at even-strength. The Oilers last season under Woodcroft posted a Corsi For percentage of 57% with a lead – one of the highest in the league, behind only Calgary and Florida. This was much higher than the Oilers have ever posted with the lead under various coaches, so there was some hope that this new coaching staff was willing to try different things to have success.

Unfortunately however, the Oilers coaching staff has been far less aggressive with the lead this season, only posting a Corsi For% of 45.6%, which ranks 18th in the league. More teams are currently playing more aggressively with the lead compared to previous season, so  it’d be interesting to see if the Oilers have purposely played more conservatively thus far or if there’s some other issues the coaching staff is dealing with. Definitely something to monitor. Either way, the team will need to explore every option, including what worked for them last season, to improve their odds of winning games and banking some more points.
