For years, the New York Rangers blueline has been a source of concern for both fans and analysts. Aside from Adam Fox, it feels like the defensive core has always been an issue. They lacked depth or just solid NHL players that could consistently put up good performances. However, this season feels different. For the first time in years, it looks like the Rangers will run out a solid blueline. A big reason for this feeling is the addition of Marcus Pettersson. He could turn out to be the most underrated move of the offseason.
How Marcus Pettersson solidifies the Rangers defense
Pettersson would like to forget this past season. In 82 games, he logged three goals and 15 assists for 18 points. His lowest point total since his rookie season of 2017-18. He also blocked 139 shots, delivered 79 hits, and forced 19 turnovers. His underlying metrics were not great either. According to Natural Stat Trick, he had a 43.72 CF%, a 43.56 SCF%, and a 44.67 xG%. A quick look at these numbers makes you question why the Rangers gave up a first to get him.
But a change of scenery could be exactly what Pettersson needs to turn his career around. Reuniting with Mike Sullivan is another positive for him. Pettersson’s best seasons in the league came when he was with the Penguins and coached by Sullivan. That defensive system allowed Pettersson to flourish. It was a fast style that put a lot of pressure on the puck and allowed him to play instinctively. Being in a familiar system will help him improve his game.

He is projected to be on the second pairing with Sean Durzi, which will also improve his game. The two’s playstyles complement each other nicely. Pettersson is more defensively responsible. He is notorious for shutting down opponent scoring opportunities. Durzi, on the other hand, is more of an offensive-minded guy. He looks to get the puck to his teammates and create scoring opportunities. The two balance each other out and create a perfect blend of offense and defense.
Playing alongside a more offensive-minded guy will allow Pettersson to focus on what he is good at. There is no pressure for him to be involved in the offense or set up players. That job will belong to Druzi. He can instead focus on playing defense and shutting down rushes the opponents go on. Putting more emphasis on the Sullivan system will make him much more effective at shutting down opposing offenses.
While Pettersson is not the flashiest move, he could be a big reason why the Rangers are better in 2026-27. It may not show on the stat sheet, but his defense should be able to help them win games.
