Why in the world you would think this makes sense is beyond me. Prime Karlsson’s not in the league right now. His scoring would be higher.
Freaking Josi scored 96 points this year.
"Freaking Josi"...as if he isn't very likely to win a 2nd Norris and join the contemporary ranks of Duncan Kieth and Erik Karlsson himself. You say that like he fluked his way into nearly 100 points. I'm assuming you have watched maybe a game or two of the Preds this year at best. Josi had an excellent year offensively and your slight against him is disingenuous.
Karlsson's infamous top 5 finish in 2015-16 was really impressive but lets not pretend that the level of forward talent i.e. competition for scoring finishes was the same then as it is now. Kane had the best year of his career but even then there was no McDavid, Draisaitl, or Matthews to bump a guy like Karlsson further down the list.
Took a quick look at my team's games vs Colorado to see what the line matching looks like. Mackinnon absolutely draws the hardest matching, and in one game he drew a 84% top pairing matchup while Makar faced almost even matching with all 3 D-pairings. Just in case anyone wanted to try to explore the ridiculous claim that line matching somehow isn't a thing. EDIT: Checked the Edmonton series and again Mackinnon was drawing the top D matchup, not Makar.
Leftwinglock's tool is pretty fantastic.

Coaches chase matchups against forward lines, not D pairs. MacKinnon gets the top D opps because he's on Colorado's top scoring line.
That's the point, a defenseman is usually not by far the best offensive player on the team the way Karlsson was, so they don't get gameplanned against the way Karlsson was. Makar is no exception.
And for your already typed out follow up to the above...the same reason Karlsson was gameplanned against against like that is the same reason he had the inflated production he did. He played on a bad team that leaned on him for everything. Which, yes he did an excellent job of it and it's why he has 2 Norris trophies and will be a HoFer.
HOWEVER, I've been saying this for 10 years now, when you play on a great team you don't get the advantage of being leaned on and therefore jacking up your goal/assists output. O-zone starts, PP minutes, PK minutes, etc...get spread out to the rest of your team. Makar's 25 minutes a night are different than Karlsson's on Ottawa were. Makar isn't out there just playing offense all game like Karlsson was. Karlsson being asked to do it all shows 1) How incredibly talented he was 2) How he could carry a franchise and 3) How bad the Sens were.
All of this is moot anyway. This thread is 23 pages of Sens/Habs fans bickering about Karlsson's woeful circumstances while all you really need to do to have an opinion on the matter is to watch Cale Makar play and it's clear as day he is the 2nd most dynamic player in the league behind Connor McDavid. Watch what Makar is capable of doing out there and I don't know how anyone can say anything other than he's the best defenseman we've seen in an extremely long time. There are too many variables and things that are not 1:1 comparisons if you try and look at this statistically. Scoring and competition is different in 2021-22 than it was in 2015-16 and you're never going to find a clear cut way to compare these two players statistically.
