This Season So Far

The 2026-27 season has not started. The empty row above is his, and both it and this paragraph fill in on their own from the morning after he first plays: what he has done, what it is worth against his own last season, and the run he is on when the two disagree.

Last Season

No goals and 16 assists in all 82 games — 16 points, minus-9, at 19:29 a night with 1,439 5-on-5 minutes, the most on the club.

The Finesse Game

There is none and none is wanted. 98 unblocked attempts from a median of 49 feet, and not one went in. 10 goals in 449 career games.

16 assists in a full season of top-pair minutes. He makes the short pass and gets off the ice, which is the job as the club has defined it.

The Physical Game

6-2, 218, and he defends the front of his net properly. 48 penalty minutes across 82 games of the hardest available assignment is disciplined for that workload.

He blocks shots, kills penalties and closes gaps without lunging.

The Intangibles

49.2 per cent of the expected goals, 48th percentile, with the chances essentially level at 58.0 and 60.0 across 1,400 minutes.

The actual goals went 43-63 against, which is 18 worse than chances that were close to level — the club-wide story, since New Jersey under-finished by 38 goals and got 10 fewer saves than the chances predicted.

9 points in his last 10, none of them goals, which is a very Siegenthaler run of form. He is 29, a second-round pick, and does the least glamorous job on a roster full of skill.

What kind of player

The searchable half of the report. The first group is computed from the season's own data; the rest are read out of the prose above, and each one carries the sentence that produced it. A subject the report never raised is simply absent.

measuredcomputed here from the season's own data

Each computed tag also says how well its measure holds up from one season to the next, because a tag describes a season that has finished and a reader will assume it predicts the one coming. Some do and some do not, and the gap is wide: five-on-five workload repeats well, scoring late does not repeat at all.

Numbers

33rd

The two rank him within 15 points of one another. It was written with these numbers on screen, so the agreement is not corroboration — the arithmetic is on both sides of it.

The same player was graded a second time from his biography and his box score alone, with the measured record withheld. That reading lands 15 points from the numbers; this one lands 15. Across the whole control the two distances come out the same, which is worth knowing in both directions: the arithmetic on both sides of the sighted reading did not buy it any accuracy, and it did not cost it any either.

All three bars are percentiles among the 656 skaters in this edition with a report and enough ice time. The report bar ranks the mean of the grades above — 69 on their own scale — against every other report's mean. The numbers bar ranks his share of expected goals. A gap is a disagreement about where he belongs, not two scales talking past each other.

Tracked

NHL Edge, 2025-26 · 82 games

Top speed: 21.2 mph; 32nd pct
Bursts over 20 mph: 0.34 a game
Distance: 2.60 miles a game
Hardest shot: 90.9 mph; 53rd pct

A top speed is a season's best, and a man who takes more shifts gets more tries at one; the percentile is the feed's own, against every skater, and says less between a top-pair defenceman and a fourth-line wing than it does between two men in the same job. The counts are shown per game for the same reason.

Usual linemates

2025-26 · 1439 minutes at five-on-five

Share of his five-on-five ice time spent alongside each player, measured from shift charts. Special teams are excluded: a power-play unit is not a line.

Why the numbers land there

Five-on-five, 2025-26

The club: NJD took 50.4% of the expected goals as a club. His own share is 49.2% — 1.2 below the club he did it on.
The role: First pair, 1,439 minutes at five-on-five — 94th percentile in ice time.

With and without

Teammate	Together	Him apart	Mate apart
Dougie Hamilton	52.1%	43.4%	52.6%
Nico Hischier	48.9%	49.3%	56.0%
Timo Meier	51.2%	48.3%	53.7%

52.1% together, 43.4% for him apart and 52.6% for Hamilton apart. He was worse away from Hamilton, who was no better away from him — he needed that pairing more than Hamilton did.

Expected-goal share while both were on the ice, and for each man in the minutes he played without the other. Apart is the pair subtracted from his own totals. It does not settle who was carrying whom — apart from each other, both were still playing with somebody — but it does say whether the share travelled when the pairing broke up.

Where he shoots from

goal on goal missed

98 unblocked shots in 2025-26, 0 of them goals. 12% of his shots came from inside twenty feet, 68% from beyond forty.
