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.

Mathew Dumba

Minnesota Wild Defense

The least ground covered of all 192 qualified defencemen, the 12th-hardest shot, and 47.5 per cent of the chances away from Jonas Brodin.

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

7 goals and 20 assists in fifty-seven games at 23:06 a night, plus-9, forty-seven penalty minutes. Seventh overall in 2012, nine seasons, 519 games, 222 points.

The Finesse Game

1.20 even-strength points per 60 is the 77th percentile and 5.28 shots per 60 the 72nd, at 6.0 per cent from a 50-foot median. Seventeen per cent from the slot, the 83rd percentile. The offensive tools are real.

100.8 mph is the 12th-hardest shot of the 192 defencemen the tracking covers. It is the loudest thing about him and always has been.

The problem is everything the shot does not touch. 51.8 per cent of the expected goals is the 65th percentile and 49.4 per cent of the attempts the 45th — and his ice went 41-44 against an expectation of 38.59-35.92, the only Minnesota regular whose shifts were outscored on a club that finished first in the league in finishing.

The pair file explains it. Across 1,386 attempts with Jonas Brodin he took 53.2 per cent. Across 479 without him, 47.5. Brodin without Dumba was at 60.3. Marcus Foligno reached 62.7 per cent with Dumba on the ice and 47.7 was Dumba’s own figure apart from him — the forwards carried this pairing, and Brodin carried it before them.

The Physical Game

5.19 hits per 60 is the 65th percentile and 3.83 blocks the 40th at 6-0 and 191 pounds. Neither is a weakness and neither is a case.

1.00 penalties taken per 60 is the 81st percentile against 0.50 drawn, and the net is the 17th. Forty-seven minutes in fifty-seven games.

The Intangibles

7.61 miles per 60 is the least ground covered of all 192 qualified defencemen in the league. He also recorded a 22.4 mph top speed, the 75th percentile, and 2.4 bursts over 20 mph per 60, the 76th.

Fast when he moves and moving less than anyone. That combination is the opposite of what this edition keeps finding under the best defencemen — Drew Doughty at the 97th percentile for ground covered and the 14th for speed, Brodin ordinary at both — and it is the most concrete thing the tracking says about the difference between them.

He is 28, plays twenty-three minutes, and the record says his club was better in the minutes he was not on the ice for. Both of those can be true at once and here they are.

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.

  • 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.

    “1.00 penalties taken per 60 is the 81st percentile against 0.50 drawn, and the net is the 17th.”

The eye and the numbers

Hindsight
Report

Numbers
69th

The numbers rank him 21 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 649 skaters in this edition with a report and enough ice time. The report bar ranks the mean of the grades above — 60 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.

Ryan Hartman58.3%48.6%53.8%

53.2% together, 47.5% for him apart and 60.3% for Brodin apart. He was the one being carried: the share went with Brodin and did not follow 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

151 unblocked shots in 2021-22, 7 of them goals. His median goal came from 20 feet. 10% of his shots came from inside twenty feet, 70% from beyond forty.
