Modern Role Icons

⇉

Puck-Moving Anchor

Defenseman who exits clean and enters controlled — play travels north on his stick, not off the glass.

≫

Neutral Zone Engine

Forward who carries through center ice for controlled entries — the transition game runs through him.

✦

High-Danger Distributor

Seeks the cross-seam and low-to-high pass — sets up high-probability chances instead of settling for perimeter shots.

↯

Rush Weapon

Counterattack specialist — top-end speed and finishing on odd-man rushes.

◎

Slot Hunter

Off-puck mover who finds soft high-danger ice in the slot for quick releases and deflections.

▣

Net-Front Disruptor

Lives at the blue paint — screens, tips, and low-slot rebounds. Goalie sightlines are never clean.

⁂

Volume Shooter

Drives offense by putting pucks on net relentlessly — the chances come from quantity plus a quick trigger.

⚒

Forecheck Monster

Offensive-zone recoveries and forced turnovers — possession is sustained by pressure, not skill plays.

⛉

Perimeter Lockdown

Defenseman who forces rushes outside and denies clean blue-line entries — the middle of the ice is closed.

■

Complete Shutdown

Center who suppresses opponent expected goals shift after shift — the matchup assignment coaches trust.

⬒

Floor Raiser

High-usage driver who carries a lineup — transition, minutes, and self-created offense keep a team afloat.

⬆

Ceiling Raiser

Adaptable elite complement — suppression, forechecking, or off-puck play that makes a great line greater.

▦

Workhorse Wall

Starter workload with saves above expected — the net is his every night and the team banks points for it.

⊘

High-Danger Eraser

Elite on grade-A chances — the slot shot that beats most goalies gets erased here.

☂

Storm Cellar

Positive goals saved above expected behind a leaky defense — the reason the scoreboard stays respectable.

◐

Tandem Weapon

Split workload, elite efficiency per start — a 1B who wins his half of the calendar.

Gravity Tiers

Supermassive

Gravity v3 tier: the largest positive bounded modelled fields in the current position-relative calibration.

Star

Gravity v3 tier: an elite positive bounded field across one or more modelled zones.

Main Sequence

Gravity v3 tier: a strong positive position-relative territorial influence index.

Satellite

Gravity v3 tier: a modest positive position-relative territorial influence index.

Asteroid

Gravity v3 tier: a bounded field near the current position-relative reference.

Black Hole

Gravity v3 tier: a strongly negative position-relative modelled field.

Player Valuation

How the app turns a player, contract, and role into tradeable asset value.

⌄

X-NAV: Extended Net Asset Value: the Ledger's skater trade-value model. Offense, defense, gravity, age curve, contract surplus, deployment, Point Shares, and role context priced into one number.
G-NAV: X-NAV for goalies. Built around GSAx, workload, save profile, team defensive context, age, and contract surplus.
Prospect NAV: Pre-NHL value comes from draft pedigree and stored NHLe production. No-signal ELC players do not receive automatic cap or age value.
OFF / DEF: On-ice components: offensive production and creation on one side, suppression and defensive value on the other, each judged against position.
GRAV: The X-NAV handoff from Gravity v3. It contains only the bounded neutral-zone transition proxy; direct offense and defensive suppression are valued elsewhere.
Modelled Field: The warped rink is a visualization generated from three model components. It is not an observed tracking heatmap or a map of puck trajectories.
Signal Stability: A v3 heuristic based mainly on current-versus-baseline on-off agreement, with a legacy defenseman pair-driver adjustment. It does not estimate portability.
Reliability: A 0–100 v3 sample, stability, and data-coverage index. It is not a calibrated probability.
Data Coverage: The share of fixed v3 zone weight backed by present inputs. Missing evidence shrinks an estimate toward neutral and lowers reliability.
Mixed Situations: Gravity v3 combines all-situations, 5v5, 5-on-4, 4-on-5, and regular-season EDGE aggregate inputs. It is not a single-strength model.
CAP: Contract component. Positive means the player is under market value; negative means the cap hit or term drags value.
AGE / YNG: Age-curve component: decline drag for veterans, youth projection for young NHL players with enough real signal. Not a blanket ELC bonus.
UPS: Upside component — development ceiling for players whose trajectory has not fully priced into production yet.
Negative NAV: Negative value does not mean a bad player. It means the contract is a trade liability relative to expected production, term, and market fit.

STRAND Glossary

The roster-DNA layer that describes style, usage, and development fit.

⌄

STRAND: Stylistic Trait & Rating Analysis for NHL Development: a team/player identity view for role fit, timeline, and roster balance.
SCR: Scoring pace. Points per 82 games, normalized by position so defencemen and forwards are not judged on the same raw scale.
xG: Expected-goals creation from shot quality and volume, not just shot count.
TOI+: Ice-time trust and role load. Heavy minutes imply broader usage and higher coaching trust.
SUPP: Expected-goals-against suppression relative to teammates. Positive means the team leaks fewer chances with that player on ice.
QoC Index: 0-100 even-strength deployment difficulty based on matchup and usage context.
DZ%: Defensive-zone start share. High usage here can indicate trusted defensive deployment.
HD Finish: High-danger finishing vs league expectation, from NHL EDGE shot-location data. Positive = converts quality chances above league rate.
20+ Bursts: Count of 20+ mph skating bursts from NHL EDGE tracking — a direct speed-in-game signal, not a one-off top speed.
AGE: Development and decline curve over the life of the contract.

Modern Roles

Derived identity labels — what a player actually does, computed from tracking, deployment, and creation-mix data.

⌄

Puck-Moving Anchor: D — clean exits and controlled entries; play travels north on his stick, not off the glass.
Neutral Zone Engine: F — carries through center ice for controlled entries; the transition game runs through him.
High-Danger Distributor: Seeks cross-seam and low-to-high passes that create high-probability chances.
Rush Weapon: Counterattack specialist — top-end speed and finishing on odd-man rushes.
Slot Hunter: Off-puck movement into soft high-danger slot ice for quick shots and deflections.
Net-Front Disruptor: Screens, tips, and low-slot rebounds — goalie sightlines are never clean.
Volume Shooter: Drives offense by directing pucks at net relentlessly.
Forecheck Monster: Offensive-zone recoveries and forced turnovers sustain possession.
Perimeter Lockdown: D — forces rushes outside and denies clean blue-line entries.
Complete Shutdown: C — suppresses opponent expected goals while on the ice; the trusted matchup assignment.
Floor Raiser: High usage — carries a lineup through transition, minutes, and self-created offense.
Ceiling Raiser: Adaptable elite complement — suppression, forechecking, or off-puck play that elevates a top line.
Workhorse Wall: G — starter workload with saves above expected; the net is his every night.
High-Danger Eraser: G — elite on grade-A chances; the slot shot that beats most goalies gets erased.
Storm Cellar: G — positive GSAx behind a leaky defense; keeps the scoreboard respectable.
Tandem Weapon: G — split workload with elite efficiency per start; wins his half of the calendar.

Trade Logic

The audit layer that decides whether a deal is plausible, not just mathematically balanced.

⌄

GM Audit: Checks clauses, cap legality, retention, roster slots, surplus gaps, timeline alignment, and contention-window fit.
EWA: Estimated Wins Added: translates asset value into standings impact, adjusted by team context.
CWI: Contention Window Index: estimates whether a trade extends, compresses, or harms a team's competitive window.
REQUESTED: Formal trade request. Positive X-NAV receives a small leverage haircut.
SHOPPED: Available or being explored by the team. No automatic X-NAV penalty.
UNTCH: Untouchable availability gate. Value remains visible, but proposal logic treats the player as unavailable.
Role Tags: First-line, middle-six, top-pair, shutdown, starter, tandem, backup, and specialist tags summarize usage/value tier.

Data & Sources

The Hockey Ledger is only possible because these sources publish world-class hockey data. Sincere thanks to each of them.

⌄

NHL API: Rosters, positions, ages, game logs, current-season summary data, and NHL EDGE tracking (zone time, speed, shot location).
MoneyPuck: Skater and goalie analytics including xG, deployment, on/off impact, and GSAx inputs. An indispensable public resource.
CapWages: Contract, cap hit, term, clause, extension, and roster metadata source.
Hockey-Reference: Point Shares and historical context for career baselines.
NHLe: Non-NHL production translated to NHL point pace for prospects. It must come from stored or imported production data.
AI Notes: AI is used for narrative explanation only; X-NAV and Gravity calculations stay in deterministic app code.

Analytical estimates only. Player values move with injury, role, performance, contract status, source coverage, and team context.
