Help appears to be on the way for Penguins

The solution to the Pittsburgh Penguins’ recent struggles is a simple one, and it appears to be on the verge of happening.

That solution: the return of a healthy Brian Dumoulin and John Marino on defense.

After both players were full participants in practice on Monday, coach Mike Sullivan confirmed they will be game-time decisions for the Penguins’ game against the Ottawa Senators on Tuesday night as they try to snap their current six-game losing streak.

Dumoulin skated next to Kris Letang at practice on Monday, while Marino was next to Marcus Pettersson.

Their pending returns is one of the biggest reasons general manager Jim Rutherford did not address the team’s blue line ahead of the NHL trade deadline. Given the way the team played defensively this season when both were healthy it’s not hard to see why they were willing to be patient.

Getting them back in the lineup not only gives the Penguins two of their top-four defensemen, it also helps get everyone else on defense back to the roles they are best suited for.

The Dumoulin impact

With Dumoulin sidelined the Penguins have been playing Jack Johnson in his spot on the top-pairing next to Letang. It has not only not worked, it has been one of the least productive defense pairings in the league by pretty much every objective measure.

Johnson had been effective earlier this season in a third-pairing role but recently was being asked to play too many minutes in a role he is simply not suited for.

Letang and Dumoulin, on the other hand, has been one of the league’s best defense pairings for the past three years. Since the start of the 2017-18 season there have 160 different defense pairings across the NHL that have played at least 500 minutes of 5-on-5 hockey together. The Letang-Dumoulin pairing ranks among the top-25 in that group in shot attempt share, scoring chance share, and is a plus-17 overall in terms of goals. Dumoulin may not be a superstar, but he is a smart, defensively sound player that possesses enough mobility and puck skills to perfectly complement Letang. They simply work together exceptionally well.

Over that same time period, the Letang-Johnson duo ranks among the bottom-20 in the same categories and has been outscored by nine goals.

Do not overlook Marino’s impact

Marino has been one of the biggest surprises in the NHL this season and has helped completely overhaul the Penguins’ defense.

He has not only been one of the best rookies in the NHL this season, he has been one of the most impactful defensive players in the entire league regardless of position or experience. Of the 517 players to log at least 500 minutes of 5-on-5 ice-time this season Marino currently ranks 73rd in total shot attempts against per 60 minutes, 17th in expected goals against, 64th in scoring chances against, and 39th in high-danger chances against. Pretty much the top 10 percent of the league across the board.

It is not a coincidence that the team’s overall defensive performance started to trend in the wrong direction when he was sidelined a few weeks ago. It was also around that same time that they lost forward Zach Aston-Reese, one of their best defensive forwards and a huge part of their shutdown line alongside Brandon Tanev and Teddy Blueger.

Marino’s return allows allows Justin Schultz to slide down to the third pairing alongside Johnson, where they can be sheltered a bit more and not have to be relied on to play more than 20 minutes a night against the other team’s best players.

It is going to make everyone better.

Even with their current losing streak the Penguins are still within striking distance of the top spot in the Metropolitan Division and were 23-6-2 in the games prior to that.
