Ask the book

2024-25 edition Ask a direct question about this edition of the book — who, how many, how common, which group more — and it is answered with a table computed on this page from the edition’s index: the season line, height and age, the on-ice percentiles, the grades and the traits read out of every report. Ask for a view on named players — what a comparison comes down to, what makes a man — and you get the book’s reading of their own pages, and only those. The model turns your question into a query and phrases the result, or reads the pages it is handed; it never originates a figure, and an answer carrying a figure that is on neither the table nor the pages is withheld. It does not forecast, and it says so when a question is outside what the book holds.

Tables are computed on this page from the 2024-25 edition’s index; readings rest on the players’ own pages; the model never counts. Twenty questions an hour.

This Season So Far

The 2024-25 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

All 82 games, 9 goals and 33 assists for 42 points, 3 on the power play, 51 penalty minutes, 22:22 a night and minus-7. He took 43.5 per cent of the expected goals at five-on-five over 1,392 minutes, the 13th percentile, and his ice went 62-69 against an expectation of 51.22-66.45.

Five goals fewer against than the chances predicted and four more for, and a minus-7 anyway. The 12th percentile is a hard number to look at and it belongs to the assignment as much as to the man: he plays the most on a club that took 45.8 per cent of the shot attempts, against whoever the other club sends out.

The Finesse Game

He carries the puck out of his own zone rather than passing it out, and at 6-2 and 210 with long strides he is difficult to separate from it once he has begun.

One hundred and thirteen assists in 246 career games is a genuine first-pair playmaking rate at 23, and it has been that from his first season. He sees the seam through the neutral zone and hits it early. One hundred and thirty-five shots at a median of 49 feet with 74 per cent from beyond 40; 21 goals in 246 career games says the shot is a delivery rather than a threat.

The Physical Game

He finishes his checks and he is unpleasant along the wall, and 51 penalty minutes in 82 games at 22:22 a night is the rate of a defenceman who initiates rather than reacts.

He clears the front of his own net at 210 pounds. That the club still ranked 27th at suppressing chances is not a thing one defenceman can fix.

The Intangibles

Sixth overall in 2019 out of Zell, a Calder at 21, and 246 games at 22:51 a night before his 24th birthday. He has been the best defenceman on this club since the day he arrived.

The chance share will look different the moment the roster in front of him does. Everything else about him already looks like a first-pair defenceman on a good club.

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
  • a strengthread out of the prose, and claimed

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.

  • hard-shot· beats a goaltender from range

The eye and the numbers

The report ranks him 38 points above where the numbers do. 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 652 skaters in this edition with a report and enough ice time. The report bar ranks the mean of the grades above — 70 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.

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

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.

42.6% together, 44.8% for him apart and 40.9% for Walman apart. Splitting them up moved neither man. Whatever is driving the share, it is not this pairing.

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

179 unblocked shots in 2023-24, 9 of them goals. His median goal came from 55 feet. 6% of his shots came from inside twenty feet, 74% from beyond forty.
