The blender is on. If you’ve watched even twenty minutes of a game lately, you know exactly what I’m talking about. Predicting the New Jersey Devils lines has become a full-time job that pays in nothing but headaches and "wait, who is skating with Jack tonight?" vibes. One minute the top six looks like a Stanley Cup contender, and the next, Sheldon Keefe has thrown the magnets at the whiteboard to see what sticks during a rough second period.
It's chaotic. It’s frustrating. But honestly, it’s also kind of the point of modern NHL coaching.
The Jack Hughes Factor and the Ripple Effect
Everything starts with number 86. Obviously. When Jack Hughes is "on," it doesn't really matter if you put him out there with two guys from the local beer league; he’s going to create scoring chances. But the coaching staff is clearly looking for that specific chemistry that made the 2022-23 season feel like magic.
Lately, we’ve seen a lot of Jesper Bratt riding shotgun with Jack. It makes sense on paper. You have two of the most creative, edge-work-heavy players in the league trying to outmaneuver defenders in tight spaces. But the problem? Sometimes they overpass. You’ve seen it. They're looking for the "perfect" backdoor play instead of just ripping the puck. That’s why the New Jersey Devils lines often feature a "grinder" or a "finisher" like Timo Meier on that wing to balance the scales.
Meier is a fascinating case study in line chemistry. He’s a volume shooter. He needs the puck. When he’s with Jack, he sometimes defers. When he’s on his own line—maybe with Nico Hischier—he becomes the focal point. Keefe has been juggling these three "pillars" (Hughes, Hischier, Bratt) to ensure that the team isn't just a one-line pony.
The Nico Hischier Security Blanket
If Jack is the lightning, Nico is the ground wire.
Nico Hischier’s line is usually where the coaching staff goes when they need to shut down an opponent’s top threat while still chipping in offensively. It’s the "safety" line. Often, you’ll see Dawson Mercer slotted here. Mercer is a Swiss Army knife. He can play center, he can play wing, and he doesn't mind doing the dirty work in the corners.
The interesting development this season has been the emergence of secondary scoring. For years, if the top two New Jersey Devils lines didn't score, the team lost. Period. Now, there’s a bit more meat on the bone. Stefan Noesen has been a revelation. Seriously. Bringing him back was one of those under-the-radar moves that changed the entire complexion of the bottom six. He adds a layer of "grease" that this team desperately lacked during their disappointing 2023-24 campaign.
Why the Bottom Six Actually Matters for the Top Six
People obsess over the power play units, but the real story of the New Jersey Devils lines is the identity of the third and fourth lines.
Erik Haula is basically the glue holding the middle of the roster together. He’s the guy you throw out there for a defensive zone draw with 45 seconds left. When the lines are clicking, Haula is usually centering a third line that plays "playoff style" hockey—straight lines, heavy hits, and pucks to the net.
Then you have the fourth line. In the past, this was a revolving door of AHL call-ups. Now? It’s a bit more intentional. You have guys like Curtis Lazar who just play hard. It’s not flashy. You won't see Lazar on many highlight reels, but his ability to kill penalties and eat up tough minutes allows Jack Hughes to stay fresh for the power play. If the fourth line can give you 8 to 10 minutes of "eventless" hockey where nothing bad happens, that’s a win.
The Defensive Pairings Shuffle
You can’t talk about forward lines without looking at the backend. The defense feeds the forwards. Dougie Hamilton’s return to health has changed the breakout completely. When Dougie is on the ice, the New Jersey Devils lines transition from defense to offense significantly faster.
- The Top Pair: Usually Jonas Siegenthaler and Dougie Hamilton. It’s the classic "stay-at-home guy plus rover" pairing. Siegenthaler’s job is basically to make sure Dougie doesn't get caught too deep in the offensive zone.
- The Young Guns: Watching Luke Hughes and Simon Nemec develop is like watching a high-wire act. There are moments of absolute brilliance followed by "oh no, what was that?" turnovers. But that’s the price of admission for elite talent.
- The Veteran Presence: Brenden Dillon was brought in for a reason. To punch people. Okay, maybe not just that, but to provide the snarl that the Devils lacked. He clears the crease. He makes life miserable for opposing forwards.
The Power Play Paradigm
The man advantage is where the New Jersey Devils lines get really spicy.
We’ve seen the "Super Unit" where Jack, Nico, Bratt, and Meier all play together with Dougie at the point. It looks great on a video game. In reality, it sometimes leads to over-complication. Lately, the coaching staff has experimented with splitting the talent. Put Bratt on one unit to facilitate and Jack on the other to create.
It’s about gravity. Jack Hughes has so much "gravity" that he draws three defenders toward him. If you have another elite shooter like Meier on the other side of the ice, the defense has to make a choice. Usually, they choose wrong.
What Most People Get Wrong About Line Changes
The biggest misconception among fans is that a line change during a game means someone is playing poorly.
"Oh, Keefe benched Mercer!"
Not necessarily. Sometimes, the coach just sees a matchup he likes. If the opposing team has a slow defensive pairing, he might throw his fastest skaters out there together for two shifts just to burn them. The New Jersey Devils lines are fluid. They aren't set in stone. In fact, if they were set in stone, the team would be too easy to scout.
The modern NHL is about "stacks" and "waves." You want a wave of pressure. If the first line creates a scoring chance and the second line immediately follows it up with another high-pressure shift, the opposing defense never gets a chance to breathe. That’s the goal in Newark.
Real-World Stats and the Eye Test
If you look at the underlying metrics—stuff like Expected Goals For (xGF)—the Devils usually rank near the top of the league. Their "process" is sound. The problem has historically been goaltending and finishing.

Jacob Markstrom changed the math.
With a reliable goalie, the New Jersey Devils lines can afford to be a bit more aggressive. They don't have to play "scared." Last year, if a defenseman pinched and missed, it was a goal against. This year, Markstrom (or a healthy Jake Allen) provides that safety net. This allows the forwards to cheat a little bit for offense, which is exactly how this roster is built to play.
Actionable Insights for Fans and Bettors
If you’re trying to keep track of where this team is headed, stop looking at the starting lineups released at morning skate. They’re a lie. Or at least, they’re a suggestion.
- Watch the first five minutes after a goal: That’s when Keefe usually shows his hand. If he goes right back to the Hughes line after a goal against, he’s hunting for a momentum swing.
- Track the "Noesen Effect": Look at whichever line Stefan Noesen is on. That line’s Corsi (shot attempts) usually skyrockets because he’s a puck-retrieval machine.
- The "Power Play 2" sleeper: Keep an eye on the second power-play unit. Often, they get the tired penalty killers and actually end up with higher-quality looks than the superstar first unit.
The New Jersey Devils lines are going to keep evolving. Between trade deadline rumors and the inevitable "lower-body injuries" that plague every NHL season, the line combinations you see today probably won't be the ones you see in April. And that’s fine. Flexibility is a strength, not a weakness. As long as the core trio of Hughes, Hischier, and Bratt are healthy, the Devils have the luxury of experimenting until they find the perfect "chemistry in a bottle" for a deep playoff run.
Keep an eye on the rookie call-ups too. The Utica Comets pipeline is always flowing, and a guy like Seamus Casey can jump into the lineup and completely change the dynamic of a defensive pairing overnight. It’s a long season. Don’t get too attached to one specific line combo. Just enjoy the chaos.

Next Steps for Devils Fans:
To truly understand the tactical side of the game, start tracking "Zone Starts" for the Hischier line versus the Hughes line. You’ll notice Nico taking the brunt of the defensive zone draws, which is the "dirty work" that allows Jack to start in the offensive zone and do what he does best. Check the post-game advanced stat cards on sites like Natural Stat Trick to see which trios actually controlled the play, regardless of who got on the scoresheet.
