Ask the book

2023-24 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 2023-24 edition’s index; readings rest on the players’ own pages; the model never counts. Twenty questions an hour.

Pittsburgh Penguins Defense

One goal from ninety-three shots on goal, and fifty-one slap shots that produced nothing at all.

This Season So Far

The 2023-24 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 23 assists in 68 games — 24 points — at 20:35 a night. Plus-4, 96 shots at 1.0 per cent, 58 penalty minutes, no power-play points.

55.2 per cent of the expected goals at five-on-five, the 85th percentile and the best share on the club’s blue line, across 1,245 minutes. His ice finished 56-56 against an expectation of 65.18-53.00 — nine goals short at the good end and three over at the other, which is a nine-goal swing against him on a club whose finishing was the worst in the league.

He started 48.8 per cent of his shifts in the attacking zone, the 40th percentile, which is the most balanced usage among Pittsburgh’s top four.

The Finesse Game

96 shots at a median of 51 feet, with 75 per cent of his attempts from beyond forty, a share only Chad Ruhwedel and Pierre-Olivier Joseph exceed on this roster.

Inside twenty feet: eight shots on goal, no goals. From twenty to forty: nineteen shots, one goal. Beyond forty: sixty-six shots on goal and no goals at all. Ninety-three shots on goal in a season and one of them went in.

That is a 1.08 per cent shooting percentage against a career 2.5. Of the defencemen in this book who put eighty or more shots on goal, only Erik Johnson, Tyler Myers and Erik Gudbranson finished lower.

And the slap shot did not help him either. He slaps 51 of his 149 tracked attempts — 34.2 per cent, the highest share on this blue line, ahead of Letang’s 32.9 and Karlsson’s 31.7 — and the return from beyond forty feet was zero from sixty-six. Three men, one defence corps, slap shares within three points of each other, and conversion rates of 9.45, 2.75 and 0.00 per cent.

This is the third time in one chapter that the shot type has failed to predict anything, and 95.3 mph at the 80th percentile says the puck leaves his stick hard. Where it is going from, and what is standing in front of it, is what this book cannot see.

The Physical Game

6-5 and listed at 174 pounds, which even allowing for the listing is a very thin frame for a man playing twenty minutes against top lines.

Top speed 21.5 mph, the 12th percentile, and 0.1 bursts above twenty miles an hour a game — the 3rd. He covers 2.83 miles a night at the 69th, so the ground gets covered; it is never covered quickly.

He defends with his stick and his reach, and the length is the whole method: he takes the lane away rather than the man, and the low burst count is a direct consequence of never having to chase.

58 penalty minutes in 68 games is high for a defenceman who does not hit, and most of it is stick work — the tax on defending from a stick’s length rather than from body position.

The Intangibles

Thirty-eighth overall in 2014, six seasons, 362 games, 103 points, five of those seasons here.

Ten career goals in 362 games. The offence has never existed and never will, and the club has used him correctly: 20:35 a night, the toughest of the balanced assignments, and a chance share in the 85th percentile.

He is twenty-seven and the youngest of the four defencemen Pittsburgh plays above eighteen minutes. On a roster this old that is worth more than the twenty-four points.

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.

  • 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.

  • defends-with-reacha strength· takes the puck before the contact happens

    “He defends with his stick and his reach, and the length is the whole method: he takes the lane away rather than the man, and the low burst count is a direct consequence of never having to chase.”

  • fouls-when-beatena strength· the stick foul that follows losing a step

    “58 penalty minutes in 68 games is high for a defenceman who does not hit, and most of it is stick work — the tax on defending from a stick's length rather than from body position.”

The eye and the numbers

Hindsight
Report

Numbers
87th

The numbers rank him 49 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 638 skaters in this edition with a report and enough ice time. The report bar ranks the mean of the grades above — 63 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.

Why the numbers land there

Five-on-five, 2022-23

The club
PIT took 53.0% of the expected goals as a club. His own share is 55.2% — 2.2 above the club he did it on.
The role
Second pair, 1,245 minutes at five-on-five — 87th percentile in ice time.

Jeff Petry53.0%56.7%52.5%
Jake Guentzel55.5%55.0%52.9%
Sidney Crosby56.1%54.6%53.3%

53.0% together, 56.7% for him apart and 52.5% for Petry apart. He was better away from Petry, who was no worse away from him — the pairing cost him more than it cost Petry.

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

144 unblocked shots in 2022-23, 1 of them goals. His median goal came from 33 feet. 8% of his shots came from inside twenty feet, 75% from beyond forty.
