The entire Sharks team is an absolute mess right now. They have the worst 5-on-5 goals for percentage and the 2nd worst 5-on-5 score-adjusted expected goals for percentage. At 5-on-5 they just got out-scored 5-1 and nearly doubled up in score/venue adjusted xGF% by the Ottawa Senators.
Karlsson in particular had a very poor game against Ottawa, and he has had a few other poor games but he also had a truly dominant game against Montreal, and he has not been nearly as poor as people are making him out to be. He has not been the worst player on the team, nor the biggest problem with this team by any stretch. Of the 15 Sharks skaters with at least 100 minutes at 5-on-5, Karlsson ranks 5th in CF% (51.34%), 8th in goals for percentage (36%), 5th in score/venue-adjusted CF% (51.25%), and 5th in score/venue-adjusted xGF% (45.72%). It's a low bar to clear, but Karlsson has been a significant positive relative to his teammates.
I know some people might not be into analytics or aware of what these numbers mean, but here is a visual look at what's going on here:
Really, those heat maps tell you all you need to know. Offensively, the Sharks actually look like a slightly above average team with Karlsson on the ice, and they look worse than any of Karlsson's old Ottawa teams Defensively, Karlsson
has done a poor job of defending, but he's also playing on a dreadful defensive team that is hardly doing any better when he isn't on the ice, and the shots that the team is facing mostly aren't coming from his side of the ice.
Part of the reason the Sharks are on pace for 62 points right now and not 40 like their 5-on-5 play would suggest they might be is because their special teams actually have been near the top of the league. Only Edmonton and Boston have a higher PP%+PK%. And the biggest reason for their PP doing well, in my view, is Karlsson. He hasn't posted a ton of points there, but he is the only player on the team who can consistently enter the zone on the PP, and he is the catalyst behind most of the offensive plays; he's been a bit unlucky in that he's had a few tertiary assists on plays that he has engineered. On the PP, the team is posting 10.11 goals per 60 minutes with Karlsson and 8.08 goals per 60 minutes without him. They're also posting 10.95 expected goals per 60 minutes with him and 5.72 expected goals per 60 minutes without him, so the gap in PP performance with and without him will only continue to widen.
On the penalty kill, the Sharks are allowing 2.08 goals per 60 minutes with Karlsson on the ice, and 2.62 goals per 60 minutes without him. Their success on the PK is mostly coming from extremely unsustainable goaltending, but they are still allowing 5.37 expected goals per 60 minutes with Karlsson on the ice, compared to 6.46 expected goals per 60 minutes without him. If "the Sharks with Erik Karlsson on the ice" were a team, they would be allowing PK goals at by far the lowest rate in the NHL, and they would be allowing expected goals at the 9th lowest rate in the NHL. So, while he won't continue to ride this ridiculous save percentage on the PK, he is playing very well there.
There are so many players that deserve criticism right now, and there are so many players that people could dump on. So why is everybody singling out Karlsson? Again, he certainly has been a problem. But he has not been the problem. I mean, Vlasic is in the 2nd year of an 8-year contract that pays him $7M per year, and he has been the worst player on the team so far after an absolutely dreadful season last year. Couture is the new captain in the first year of an 8-year contract that pays him $8M per year, and he hasn't been very good either. Peter DeBoer is in the first year of a new contract extension with an undisclosed term, and his teams have now been out-scored at 5-on-5 since the start of the 2017-2018 season. The Sharks are 4-7-1 without their 1st round pick and it seems like the only player that anybody wants to dump on is Karlsson. I don't get it. There's plenty of criticism to be had for Karlsson who simply hasn't been good enough so far but for ****'s sakes, share the love, guys! There is
more than enough to go around!
