Peer value
A player's value ranked within their own role, not against the entire league - a fairer read for depth players who will never out-GAR a franchise center.
Why role-relative
Ranking every skater on one list buries a shutdown third-pair defenseman beneath a first-line scorer, even when the defenseman is excellent at his job. A depth forward will never out-produce a franchise center, and holding him to that bar tells you nothing about how well he plays his actual role. Peer value fixes the comparison: each player is ranked and percentile-scored only against others in the same season who play the same role. The result answers a cleaner question - not 'is this the best player in the league?' but 'is this the best player at this job?'
How the peer group is drawn
A peer group is a position group crossed with a usage tier, cut fresh each season. Skaters are split into forwards and defensemen, then into thirds by season-long ice time within that position: Top-6, Middle-6, and Bottom-6 forwards, and Top-4, Pairing, and Third-pair defensemen. Goalies split into Starters and Backups by workload. That yields eight self-contained cohorts, each ranked from best to worst on its own scale. Within a cohort, skaters are ordered by their per-season all-in-one value (GAR) and goalies by their shot-quality-adjusted goaltending (GSAx), and the percentile runs 0 to 100 with 100 the best in the group.
How it stays honest
Two guardrails do the work. First, an eligibility gate: only players with at least 20 games in a season (20 starts for goalies) are ranked, so a hot handful of games can't manufacture a peer-group crown. Second, every cohort is genuinely self-contained - a player's rank runs 1 through N inside their own tier and nowhere else, and the reported group size is exactly the number of players ranked against them. There is no bleed between tiers and no cross-season leakage: the comparison set is fixed to same-season, same-role peers before anyone is scored.
What the cohorts actually look like
Because this is a ranking rather than a prediction, its integrity is a matter of sampling discipline, so it's worth showing exactly how the cohorts sit. Across the 2020-21 through 2024-25 seasons the tier sizes are stable and sensible - roughly 150-plus qualified forwards, about 80 defensemen, and two-to-three dozen goalies per tier per season - and the eligibility gate holds with zero exceptions.
| Cohort | Typical size per tier, per season | Ranked on |
|---|---|---|
| Forwards (Top-6 / Middle-6 / Bottom-6) | ~154 (range 143-161) | Per-season GAR |
| Defensemen (Top-4 / Pairing / 3rd-pair) | ~79 (range 71-84) | Per-season GAR |
| Goalies (Starter / Backup) | ~26-27 (range 15-31) | Per-season GSAx |
As a concrete example, in 2023-24 each of the three forward tiers held exactly 156 players, each defense tier held 84, and there were 31 Starters and 31 Backups - and within every one of those tiers the rank ran cleanly from 1 to the tier's size, with no player slipping the 20-game floor.
Validation figures reflect the data through 2025-26 and are recomputed each season. Head-to-head benchmark tests (log-loss, AUC, bootstrap intervals) are dated snapshots of a specific held-out season, labeled where they appear.
