Ask the book

2022-23 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 2022-23 edition’s index; readings rest on the players’ own pages; the model never counts. Twenty questions an hour.

Rasmus Dahlin

Buffalo Sabres Defense

Fifty-three points and 24:01 a night at twenty-two, off a 97.7 mph shot from a median of 54 feet — and a minus-22 behind it.

This Season So Far

The 2022-23 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

13 goals and 40 assists in 80 games — 53 points at 24:01 a night, minus-22, with 3 power-play goals on 170 shots and 68 penalty minutes.

Twenty-four minutes a night at twenty-two, the 91st percentile among defencemen, with 3:05 of power play — the 94th — and 40 per cent of his points scored on it.

46.4 per cent of the expected goals at five-on-five over 1,580 minutes, the 26th percentile. His ice went 57-67 against an expectation of 56.7-65.53 — the scoring landed exactly where the chances said and the goals against did too. Nothing about the minus-22 is luck. It is a description of the minutes.

3.52 miles a game is the 97th percentile among the skaters this book tracks. Nobody in Buffalo covered more ground.

The Finesse Game

129 assists in 277 games before his twenty-third birthday, and he leaves his own zone with the puck rather than passing it away. That is the skill, it has been visible since he was eighteen, and it is why the point totals keep rising on a club that keeps losing.

170 attempts at a median of 54 feet — the 90th percentile for distance — with 9 per cent from inside the slot, off a 97.7 mph shot at the 79th. Thirteen goals off a point shot is a 7.6 per cent conversion at the 87th percentile, and it is the volume from distance rather than any deception that produces them.

The Physical Game

6-3 and 204, and the defending is the part that has not arrived. 2.84 blocks per 60 is the 10th percentile among defencemen and 3.78 hits at the 47th. He is not in front of shots and he does not finish checks, and on 24 minutes a night that shows.

1.03 penalties taken per 60 is the 84th percentile — he fouls when the gap goes, and the gap goes because the top speed is 21.4 mph, the 22nd percentile. He is not fast in a straight line; he is agile, and the tracking cannot see the difference.

The Intangibles

First overall in 2018, 277 games by twenty-two, 160 points, and a minus-78 across all of them.

He is 22, a restricted free agent this summer past, and the most important player in the organisation. Everything Buffalo does for the next five years is built on the assumption that a defenceman who takes 46 per cent of the chances at twenty-two takes 53 per cent at twenty-six — and there is nothing yet in the measured record that either confirms or refutes it.

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
  • he lacks itraised, and he does not have it

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.

The eye and the numbers

Hindsight
Report

Numbers

The report ranks him 58 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 649 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.

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.

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.

BUF took 46.3% of the expected goals as a club. His own share is 46.4% — 0.1 above the club he did it on.

44.9% together, 47.5% for him apart and 46.6% for Jokiharju 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

218 unblocked shots in 2021-22, 13 of them goals. His median goal came from 35 feet. 8% of his shots came from inside twenty feet, 78% from beyond forty.
