Jonas Siegenthaler
New Jersey Devils Defense
A 52.6 per cent chance share in 55 games, and a shutdown defenceman who cannot stay available.

This Season So Far
The 2025-26 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
2 goals and 7 assists in 55 games for 9 points, plus-9, on 19:36 a night.
52.6 per cent at five-on-five, the 76th percentile, over 941 minutes. His on-ice goals were 37-31 against an expected 34.8-31.3. 55 games is the third consecutive interrupted season.
The Finesse Game
Essentially none. 52 shots and 2 goals, and 7 assists in 55 games at 20 minutes a night is among the lowest offensive returns in this edition.
The first pass is short and safe. He is on the ice to defend and does nothing else.
The Physical Game
6-2 and 218, and he defends properly. He clears his crease, blocks shots, and is difficult to get around at the blue line.
44 penalty minutes over 55 games is a moderate rate. The availability is the recurring problem — a broken foot and a back issue in consecutive years.
The Intangibles
A second-round pick, two organisations, and a decade of being one of the more underrated defensive defencemen in the league.
At 28 the projection is 60 games of very good defending. This blue line has three defencemen who can take a hard matchup and none of them plays a full season.

The eye and the numbers
HindsightThe numbers rank him 29 points above where the report does. It was written for a back edition, with the seasons that followed already known. Neither the agreement nor the gap says anything about the eye, and this report is excluded from the club-level comparison for the same reason. Why the numbers land there sets out the club he did it on, the minutes he played and the men he played them with.
Both bars are percentiles among the 357 skaters in this edition with a report and enough ice time. The report bar ranks the mean of the grades above — 72 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.
Usual linemates
2024-25 · 941 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, 2024-25
- The club
- NJD took 50.7% of the expected goals as a club. His own share is 52.6% — 1.9 above the club he did it on.
- The role
- Second pair, 941 minutes at five-on-five — 52nd percentile in ice time.
With and without
| Teammate | Together | Him apart | Mate apart |
|---|---|---|---|
| Johnathan Kovacevic | 53.9% | 47.3% | 51.6% |
| Timo Meier | 48.8% | 55.1% | 55.5% |
| Nico Hischier | 48.0% | 55.0% | 56.4% |
53.9% together, 47.3% for him apart and 51.6% for Kovacevic apart. He was worse away from Kovacevic, who was no better away from him — he needed that pairing more than Kovacevic 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
77 unblocked shots in 2024-25, 2 of them goals. His median goal came from 63 feet. 4% of his shots came from inside twenty feet, 64% from beyond forty.
