The Edmonton Oilers have been very poor since the 4 Nations Face-Off. In 10 games since the break, they have three wins and seven losses, having been outscored 27-40 in all situations.

Even-strength (5v5) has especially been awful as the club went from a +14 goal differential heading into the break to now sitting at even. Put another way, it took them 55 games to have a goal-share of 53 percent, which was eighth best in the league. And all of that progress, especially what they did in January, has been wiped out in the last ten games. They now rank 18th in the league with a goal share of 50 percent. Not exactly looking like a playoff threat. A graph showing the Oilers cumulative goal differential this season at even-strength is below.

The drop-off in results has been driven by their inability to control the flow and their spending less and less time with the puck. Prior to the break, the Oilers had some of the best shot-share numbers in the league, hovering around the 55 percent mark when it came to Corsi percentage (which is a proxy for puck possession) and Expected Goals (which is a proxy for scoring chances). But since the break, these numbers have fallen to league average levels, with their Expected Goals percentage even dropping below 50 percent.

For context, below is the Oilers underlying shot-share metrics in rolling 10-game segments. I’ve added a marker at the 55 game mark, which is the first game after the Four Nations Faceoff tournament. The other low point came around the game 34 mark, which was in late December when the team was struggling. In January, the team turned things around and started playing closer to what was expected. But things appear to have fallen off again. The recent numbers are well below where they were prior to the break and an indication that the tactics and process the coaching staff has in place for even-strength play isn’t working. The results are suffering because of it, and it has to be addressed as soon as possible.

There are two issues to consider when trying to understand why these numbers are falling off.

The first is that the team’s goaltending has been a weak spot for the team for a long time now, and hasn’t at any point this season been at or above league average levels. Because of this weakness in net, the team seems to be playing a little too safe now and not pushing for offence as frequently. Instead of taking chances and really leveraging the offensive talent they have up front, there are a few too many conservative plays happening, especially in this recent stretch of games.

The switch to playing more conservatively at even-strength is reflected in the team’s declining rate of generating shot attempts. Before the tournament break, the Oilers were generating 62.6 shot attempts per hour — one of the highest in the league. In the last ten games, that rate has dropped by 8.8 percent to 57.04 shot attempts per hour — which is slightly below league average.  Worth mentioning that the team’s rate of shot attempts against has remained steady all season.

And as I wrote about a month ago, the team has also been getting a lot more shots from their defencemen, which isn’t ideal considering the probability of scoring drops off the further you’re away from the net. There appears to be more hesitancy to make plays and take some risks to get the puck moving into high danger scoring areas. Instead, the team is taking shot attempts from distance, and hoping the best for rebounds. This is a weird tactical issue that various coaching staffs have tried in Edmonton, and it just doesn’t work well.

Considering the team’s championship aspirations, and the importance of home-ice, it’s critical that the Oilers coaching staff recognize the issues and make the necessary adjustments. The chase for a division title is slowly slipping away, but there is still time to make some ground.
