The comparable set.
Chosen by a printed rule, not by feelNHL dossier pool · 1,162 careers
Selection rule. Goaltenders only; career games played within ±20% of 1 (or ±10 games, whichever band is wider: 1 to 11); then the five nearest by career SV%, ties broken by the closest games played. The pool is the 1,162 players in this site's NHL dossier set who own at least one official regular-season game: 24 of them cleared the band.

Similar career shape is not similar player. The rule matches volume and rate only; it knows nothing about era, position within the group, usage or role, and two careers can land on the same line for opposite reasons.

Insights
NHL Edge tracking.
Measured puck and player trackingNHL Edge tracking · api-web.nhle.com · coverage from 2021-22 · fetched 2026-08-17
No Edge tracking on file for Sebastian Cossa. The league publishes Edge for goaltenders from 2021-22 onward, and only for players it tracked in the covered season. Nothing is drawn here as a zero, because the absence is a coverage fact rather than a measurement.
Who solves him.
Every shooter on record against him · 3 seasonsNHL play-by-play · 2023-24, 2024-25, 2025-26 · 4,192 games · fetched 2026-08-18
17 shots on goal faced from 12 different shooters, 3 of them scored: 17.6% against, on a league baseline of 10.2%. 3 of those shooters have scored at least once.
Hunters: 3 or more goals on him
Nobody in this dataset has scored 3 on him. The threshold is not lowered to fill the board.
Method: goals, shots on goal and missed shots are attributed to the goaltender the feed says was in the net (details.goalieInNetId). Blocked shots are excluded, the puck never reached a goaltender, and empty-net events are excluded, because there was no goaltender to charge. Shooting percentage is goals divided by shots on goal, the league definition, in which shots on goal already include goals. The two board thresholds (3+ goals; 10+ shots at 15% or worse) are ported from the source project and printed here rather than left implicit. This is a count of what happened, not a rating of the goaltender.

Development Trails uses its own declared clock. Missing evidence stays unavailable rather than being drawn as zero.
