Ask the book

2025-26 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 2025-26 edition’s index; readings rest on the players’ own pages; the model never counts. Twenty questions an hour.

Joonas Korpisalo

Boston Bruins Goaltender

An .8932 in 27 games, and a backup whose numbers are indistinguishable from the starter's.

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

11-10-3 in 27 games, .8932 with a 2.90 average and 3 shutouts on 693 shots.

A lower goals-against average than the starter and a save percentage within a point of him, in half the games. On a club this poor that is neither an endorsement nor a criticism; it is two goaltenders having the same season.

The Physical Game

6-4 and 200, and he plays a large, positional game — deep, square, and reliant on size rather than quickness.

The lateral movement is the weakness and it always has been. A puck moved across the slot beats him more often than it should, and the rebound control is the worst of the two goaltenders here. Behind a club that concedes as many second chances as this one that is the wrong pair of flaws.

The Mental Game

Eleven seasons, five organisations, and a career of alternating between a good half-season and a bad one. He has been a starter, lost the job, been traded, been bought out of the situation, and kept working.

There is no evidence of a goaltender who unravels, and none of one who strings together three good months.

The Intangibles

At 31, doing the job he is suited to: 25 starts, no expectations, and a modest cost.

The useful thing about him on this roster is that he can play 30 games without the club being obviously worse, which is what a rebuilding team needs from a backup while it finds out what its starter is.

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
  • 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.
