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

1 goal and 13 assists in 35 games — 14 points at 21:10 a night, plus-1, on 2 penalty minutes. He missed more than half the season.

54.7 per cent of the expected goals at five-on-five, the 89th percentile, across 634 minutes. His ice went 27-19 against an expectation of 29.50-24.43 — three goals of scoring missing and five fewer conceded than the chances predicted.

The Finesse Game

30 attempts in 35 games at a median of 49 feet with 74 per cent from beyond 40, and 1 goal. He does not shoot: 19 goals in 363 career games.

13 assists in 35 games is a strong rate and it comes from the breakout. He retrieves the puck quickly, he escapes the first forechecker, and the first pass is early and accurate.

The Physical Game

6-1 and 200 and he defends almost entirely with his stick and his positioning. He does not clear a crease by force.

2 penalty minutes in 35 games at twenty-one minutes a night is close to the lowest rate anybody has recorded in this edition. He is essentially never beaten badly enough to have to reach, which is the whole of his defensive case.

The Intangibles

A sixth-round pick of Edmonton in 2015 who went to Harvard, did not sign, and was traded to Pittsburgh for a fourth-round pick — 363 games and 121 points across three organisations.

He is 28. Injuries cost him most of last season and he has been one of the more quietly effective defensive defencemen in the league when available.

The eye and the numbers

Hindsight
Report

Numbers
89th

The numbers rank him 40 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 637 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 · 634 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
UTA took 53.2% of the expected goals as a club. His own share is 54.7% — 1.5 above the club he did it on.
The role
634 minutes at five-on-five — 24th percentile in ice time.

With and without

Mikhail Sergachev55.5%53.1%50.7%
Nick Schmaltz47.4%58.2%53.9%
Clayton Keller44.6%59.1%53.9%

55.5% together, 53.1% for him apart and 50.7% for Sergachev apart. Sergachev was worse away from him while his own share held — the pairing was doing more for Sergachev than for him.

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

42 unblocked shots in 2024-25, 1 of them goals. His median goal came from 56 feet. 10% of his shots came from inside twenty feet, 74% from beyond forty.
