Early-season line combinations were already driving Pete DeBoer back to the drawing board after just one game with the New York Islanders. The season-opening loss to Toronto exposed something that weeks of practice couldn’t completely prepare his forwards for: the unforgiving speed of meaningful NHL hockey.
By October 2, DeBoer had changed his forward lines. Inside Northwell Health Ice Center, the Islanders returned to work with different assignments and an uncomfortable question hanging over their roster. Who actually belonged together?
Emil Heineman moved alongside Bo Horvat and Kyle Palmieri. Simon Holmström reunited with Jean-Gabriel Pageau. Two young forwards found themselves skating beside veteran Brayden Schenn. DeBoer wasn’t searching for an exciting experiment. He needed five-on-five goals, cleaner defensive coverage, and combinations he could trust when games tightened.
That makes finding the right forward mix one of October’s highest-stakes puzzles. Across the NHL, coaches face the same problem. Shorter camps have squeezed preparation time, while an expanded regular season gives teams even less room for prolonged struggles.
The puzzle gets harder when rookies, trade acquisitions, and established veterans fight for the same top-six minutes. One poor shift can expose a broken partnership. Yet abandoning that partnership too quickly might destroy something worth building.
Shorter Training Camps Have Made October Less Forgiving
The NHL’s new calendar changed the opening weeks before a single puck dropped.
In July 2026, the league announced an 84-game regular season, its longest schedule since 1993-94. The expansion came through the new collective bargaining agreement, adding one home game and one road game against divisional opponents.
Those extra rivalry games came at a cost. Teams now play a maximum of four preseason games rather than the six to eight exhibitions many previously scheduled. The change gives coaches less time to experiment before wins and losses begin counting.
NHL.com senior writer Tom Gulitti examined the compressed schedule in September. He reported that clubs opening September 29 had only 12 days between their first practice and opening night. New York Rangers coach Mike Sullivan explained that game days and mandatory rest left his team with roughly six practices to prepare.
Six practices. That’s barely enough time to install a defensive structure, never mind discover three forwards who instinctively understand one another.
A veteran defenseman might give a rookie an extra beat to make a play during a meaningless exhibition. In October, that window snaps shut. Forecheckers arrive harder. Sticks crowd passing lanes. A winger who hesitates along the boards can suddenly hear opposing skates carving toward his own net.
Early-season line combinations no longer have weeks of exhibition hockey to develop naturally. Coaches must assess chemistry while protecting valuable standings points. A struggling line might need patience, while another could require immediate surgery. Knowing the difference has become a serious coaching advantage.
Why NHL Coaches Build Chemistry Around Pairs Instead of Entire Lines
Three talented forwards don’t automatically make one effective unit.
Give a coach three natural shooters, and someone still needs to retrieve the puck. Put three aggressive forecheckers together, and they might generate tremendous pressure while leaving nobody available for the finishing pass. The trick lies in balancing responsibilities.
Dan Lambert discussed that philosophy in a November 2025 NHL.com coaching column. The former NHL assistant coach explained his preference for building combinations around two compatible players before choosing a third.
That final forward can change according to matchups, injuries, or tactical needs. It’s a practical answer to hockey’s constant movement.
Ottawa’s Stützle-Batherson Partnership Shows What Familiarity Buys
The Ottawa Senators entered October 2026 with one partnership already firmly established.
Coach Travis Green placed Tim Stützle and Drake Batherson together on the first day of training camp. Their relationship didn’t need much introduction. Ottawa’s official team reporting revealed that the pair had played nearly 4,000 regular-season minutes together since Stützle entered the league in 2020-21.
They knew each other’s habits. Stützle understood when Batherson would drift toward open ice. Batherson recognized when his center wanted to attack through the middle rather than retreat toward the boards.
The benefits appeared immediately. Through Ottawa’s first three games, Stützle recorded three goals and three assists. Batherson added two goals and an assist.
On October 5 against Boston, Stützle scored twice during an explosive first-period sequence. Later, he sprung Batherson on a breakaway that beat Jeremy Swayman.
It wasn’t just the finishing. Ottawa defenseman Jordan Spence praised their defensive-zone play and their ability to create something from difficult situations. That’s the kind of chemistry coaches crave: knowing where a linemate is heading before the puck arrives.
Dallas followed a similar blueprint under Glen Gulutzan during its 2025 preseason.
Stars reporter Mike Heika detailed how Matt Duchene and Tyler Seguin worked with different supporting forwards, including Justin Hryckowian and Sam Steel. Their existing relationship gave Gulutzan freedom to experiment without dismantling the entire unit.
The approach illustrates why early-season line combinations often revolve around dependable partnerships rather than permanent trios. Two players supply the foundation. A third changes the personality of the line.
For coaches, that’s much easier to manage than rebuilding every forward combination after an injury or disappointing game.
Why the Box Score Can Fool Even Experienced Coaches
A line scores twice in three games. Fans demand more ice time. Another unit goes scoreless while repeatedly trapping opponents in their defensive zone.
Which one actually played better?
The answer isn’t necessarily obvious from the scoreboard. NHL coaching staffs now have access to far more information than goals, assists, and plus-minus ratings.
They study shot attempts, high-danger chances, puck recoveries, controlled exits, and five-on-five possession. Services such as Natural Stat Trick help illustrate where teams generate their offensive pressure. NHL EDGE advanced stats provide additional tracking information about skating, shooting, and individual performances.
None of those tools can replace watching the game. They can, however, prevent coaches from overreacting to one fortunate bounce.
The Difference Between Scoring Goals and Driving Play
Imagine a line that spends an entire shift cycling below the opponent’s goal line.
The center wins two puck battles. His right winger feeds the slot. A defender blocks the resulting shot, and the puck eventually leaves the zone. No goal. No assist.
But the shift still reveals something useful. Those forwards maintained possession, created a dangerous opportunity, and forced opponents to spend energy defending.
Now consider another line. One harmless-looking shot hits a defender’s skate, changes direction, and slips past the goaltender. The scoreboard rewards that unit, although its overall performance might tell a different story.
This distinction drives much of the scrutiny surrounding early-season line combinations. Coaches want repeatable offensive habits, not scoring luck.
Deployment Changes the Meaning of Every Statistic
A checking line buried in its defensive zone plays a different game from a sheltered scoring unit.
The first group might face an opponent’s best forwards, handle difficult defensive-zone faceoffs, and spend crucial minutes protecting a lead. Meanwhile, the second receives favorable matchups and frequent offensive-zone starts.
Comparing their raw scoring totals makes little sense. Analysts therefore examine scoring chances relative to opposition, ice time, and game situations.
Even expected-goals models require caution over tiny samples. Four games might reveal a concerning trend, but they rarely provide enough evidence for a definitive judgment about chemistry.
Coaches must decide whether they’re seeing an actual problem or ordinary October randomness. That uncertainty makes the job maddening.
Defensive Mistakes Can Break a Line Faster Than Missed Chances
A missed scoring opportunity usually brings disappointment. A missed defensive assignment can bring an immediate line change.
Picture a winger drifting toward the opposing blue line, hunting for a breakaway. Behind him, his defenseman retrieves a loose puck near the corner. Two forecheckers close in, shoulder to shoulder, cutting off the boards.
The winger has already blown the zone. His defenseman now faces a heavy two-man forecheck without the short passing option that should have been available. A rushed clearance hits an opponent’s stick, and suddenly the puck heads straight toward the slot.
The goaltender makes the save, but the coach has seen enough. That single sequence can reveal more about a forward’s reliability than three impressive offensive shifts.
The Small Responsibilities That Earn Big Minutes
NHL defensive coverage demands constant communication.
A center must recognize when to support his defensemen below the faceoff circles. His wingers need to identify opposing point men, close passing lanes, and react when coverage shifts.
These decisions happen almost instinctively on established lines. New combinations require more communication.
One player expects a teammate to pursue the puck carrier. His partner anticipates a switch. Both hesitate, leaving the attacker with enough space to reach the dangerous middle of the ice. That’s how defensive-zone breakdowns begin.
When the game hangs in the balance, coaches lean on players with high hockey IQ, not just fast feet.
A defensively dependable winger might never produce 30 goals. Still, his positioning can allow a gifted center to attack more confidently. He wins a puck along the wall. He makes the short pass under pressure. Above all, he recognizes when the correct play means staying behind the puck.
Early-season line combinations succeed when all three forwards understand that defensive trust creates offensive freedom. The prettiest goals attract attention. The ugly little puck battles often determine who earns another shift.
Pete DeBoer’s Islanders Show How Quickly the Puzzle Changes
The Islanders’ opening week provided a particularly revealing example.
DeBoer had taken over New York in April 2026, replacing Patrick Roy. His arrival followed several important roster changes.
The Islanders acquired Calum Ritchie from Colorado in the March 2025 Brock Nelson trade. They selected Victor Eklund with the 16th pick of the 2025 NHL Draft. Brayden Schenn joined from St. Louis in a March 2026 trade.
By October, DeBoer had a roster blending familiar veterans, recent acquisitions, and developing prospects. Making those pieces work was another matter.
Following New York’s September 30 loss to Toronto, DeBoer reshuffled his forward combinations at practice on October 2.
The Islanders’ official practice report confirmed the new alignment. Emil Heineman joined Bo Horvat and Kyle Palmieri. Simon Holmström returned to a line with Jean-Gabriel Pageau and Anthony Duclair.
Meanwhile, Eklund and Ritchie skated alongside Schenn, a veteran with more than 1,000 NHL games behind him.
One Adjustment Creates Three Different Tests
DeBoer’s changes weren’t random.
Heineman received an opportunity beside established offensive players. Holmström returned to a familiar partner with whom he also shared penalty-killing responsibilities. Schenn became the experienced presence alongside two young forwards still learning the demands of consistent NHL hockey.
Each decision served a different purpose.
The Horvat unit needed offensive production. Pageau’s line required dependable two-way play. Schenn’s assignment offered Ritchie and Eklund a chance to develop within a veteran-supported structure.
But DeBoer wasn’t enjoying the constant adjustments.
“I don’t like to flip lines around,” DeBoer admitted in the Islanders’ official October 2 practice report.
The frustration was understandable. New York hadn’t generated enough five-on-five offense, even during exhibition games. DeBoer wanted stable partnerships, but his forwards weren’t giving him enough reasons to keep them together.
That problem extended beyond individual chemistry. Moving Heineman upward altered the balance elsewhere. Reuniting Holmström and Pageau changed another line’s identity, while the rookie partnership needed enough offensive opportunities without exposing the team defensively.
Early-season line combinations force coaches to think about all four forward units simultaneously. One successful promotion means little if the remaining lines become impossible to trust.
New York’s situation captured that tension perfectly. A coach wants consistency, but his lineup keeps demanding adjustment.
Young Players Have Even Less Time to Earn a Coach’s Trust
For established veterans, a disappointing October can mean changing linemates. For young players, the consequences can reach further.
A rookie struggling through defensive assignments might lose offensive-zone opportunities, fall down the depth chart, or face a reassignment to a development league. That’s a heavy burden for someone still adjusting to NHL speed.
The transition often exposes weaknesses that dominated junior or European players could previously overcome through skill.
A prospect might beat defenders with speed during training camp. Against experienced NHL opposition, he discovers that opponents anticipate his preferred moves. Passing lanes disappear. Board battles become nastier. Mistakes arrive with an audience of thousands.
Coaches must identify which problems will disappear through experience and which require different assignments.
The Islanders’ decision to place Ritchie and Eklund alongside Schenn offered one solution. Schenn could provide experience in difficult situations while allowing the younger forwards to develop their own offensive understanding.
Such arrangements don’t guarantee instant results. They give prospects a structure in which coaches can better judge their progress.
A young player might demonstrate excellent skating while repeatedly drifting away from defensive responsibilities. Another may contribute little offensively but consistently win contested pucks. Both observations matter.
Early-season line combinations are as much about player development as immediate offensive production. The key lies in giving prospects enough opportunities to improve without asking the entire team to absorb every mistake.
Special Teams and Matchups Add Another Layer of Scrutiny
A forward who excels on the power play doesn’t automatically fit beside the same players at five-on-five. The responsibilities change dramatically.
With a man advantage, skilled forwards can work through established passing formations. They have extra space and often spend extended stretches attacking. At even strength, opponents close that space with another defender.
A winger comfortable waiting near the faceoff circle on the power play might struggle when asked to retrieve pucks against an aggressive forecheck. Coaches must judge those performances separately.
Home-ice matchups create another complication.
The home team’s last-change advantage lets coaches target favorable combinations after stoppages. Road opponents can respond by sending their strongest defensive players against a visiting team’s scoring line.
Suddenly, a partnership that thrived against weaker opposition faces a much tougher examination. That difference can show up in puck possession, scoring opportunities, and defensive breakdowns.
Sometimes a line simply encounters a difficult matchup. Other times, the matchup reveals a weakness opponents can exploit repeatedly.
The challenge isn’t finding three forwards who work together under ideal conditions. It’s finding three who can survive when the opposing coach has every reason to make their night miserable.
What October’s Line Changes Could Mean by Spring
October offers an unusual mix of urgency and uncertainty.
Every point matters. Every roster decision attracts attention. Yet coaches still know relatively little about how their newest combinations will perform across a full season.
The expanded 84-game schedule makes that uncertainty more consequential. Teams will face additional divisional opponents while navigating the familiar punishment of back-to-back games, travel, injuries, and exhausted legs.
A clicking forward line hands a coach a nightly lifeline. When one unit struggles, another can maintain offensive pressure. If a winger gets hurt, a reliable two-player partnership gives the staff a foundation for finding his replacement.
That flexibility becomes invaluable as the playoff race intensifies. But chemistry cannot develop entirely through video sessions and lineup diagrams.
Players need shared shifts. They need to learn how a center reacts when a forechecker closes from behind, where a winger moves during a contested breakout, and when a teammate prefers a pass into space rather than directly onto his stick.
Those instincts require repetition.
Early-season line combinations deserve scrutiny because coaches must balance two competing demands: building chemistry and winning immediately.
Too much tinkering prevents players from developing trust. Too much patience allows obvious weaknesses to linger. Neither approach offers an easy answer.
The Islanders’ October adjustments show how quickly those decisions arrive. Ottawa’s established Stützle-Batherson partnership demonstrates what familiarity can provide. Dallas offers another reminder that reliable duos give coaches options when circumstances change.
Some October combinations will disappear before Thanksgiving. Others will gradually become the foundation of a team’s identity.
The most valuable partnerships might not even lead their teams in scoring. They could emerge through a defensive-zone faceoff, an important penalty kill, or a grinding third-period shift that protects a one-goal lead.
When spring hockey arrives, coaches will remember those details.
And somewhere in October, a young winger will learn to stop chasing the breakaway, turn back toward his defenseman, and make the simple pass that keeps his line together.
No highlight reel will celebrate it. But for Pete DeBoer and the Islanders, that small act of trust could be the reason a line finally stays together.

FAQs
Q1. Why do NHL coaches change line combinations early in the season?
Coaches change lines to improve chemistry, fix defensive mistakes, and generate more scoring chances. Shorter training camps make those early adjustments more urgent.
Q2. How do NHL coaches know if a forward line has good chemistry?
Coaches study puck possession, passing habits, defensive coverage, and scoring chances. They also watch how naturally players anticipate each other’s movements.
Q3. Why do some NHL coaches build lines around two players?
Two established partners provide consistency. Coaches can then rotate the third forward to create better matchups or respond to injuries.
Q4. Can a player lose his NHL line spot because of defensive mistakes?
Yes. Missed assignments and poor positioning can cost a player ice time, even when he produces goals.
Q5. How does the shorter NHL preseason affect line chemistry?
Fewer exhibition games leave coaches less time to experiment. Players must develop chemistry during regular-season games while competing for standings points.
