How to read this map

One rink, both ends while Zachary Bolduc is on the ice: what the team generates on the left, what it concedes on the right. Every attempt is a Gaussian bump of height = its model xG, summed per 60 minutes of ice time (a player's exposure is time, not games). The controls switch the surface (xG heatmap ↔ vs league, the league baseline per team-hour at the same strength) and the markers: × goal · • on net · ◦ missed · small • blocked — and own shots narrows the left end's markers to attempts Zachary Bolduc took.

The page opens at 5v5; empty-net attempts are excluded throughout. On-ice membership comes from the shift charts; attempts without usable shift coverage are absent from both ends. Blocked-shot membership cannot be cross-checked against the play-by-play, so treat blocked-marker detail as softer than the rest.

Percentiles rank against the other forwards over the display floor at the selected strength — a non-strength filter (rush, period, …) moves the bars but keeps that strength's spread as the backdrop.

Ranked against forwards; the band behind each bar is that cohort's spread (p5–p95, middle half brighter, dashed median), so where a bar lands against its band is the rank — the ordinal beside it makes that exact. Zero is whichever baseline the toggle selects — the league-average skater, or replacement level — and every row, its band and its ordinal are all drawn against that one baseline, so the bar and the number can never describe different things. Each row's bar grows from zero, so its end IS its value; the composite is the rows stacked, running both ways from zero, so only it carries a ▽ to mark the net. The rows sum to the total with nothing left over. The per-shot rating is quality only: it says nothing about how many attempts a player generates or faces, which is what the attempts figure is for.

Usage & context

descriptive · not modeled
The job the coach handed Zachary Bolduc, not how well it went. Not a modeled component: each is its own metric (minutes, a rate, a TOI share, or opponents'/teammates' net xG-RAPM), shown with a cohort percentile only where one exists, never added together. Not a grade. The deployment rows are measured over the same 5v5 stints the isolate is fit on (regular season + playoffs); ice time and the penalty rates are all situations, every game — penalties create non-5v5 time, so a 5v5 denominator would inflate every rate.

A skater absent from the fit counts as exactly cohort average (0) in QoC/QoT — the same claim ridge shrinkage makes. Penalty rates are descriptive only: taken-rate includes defensively correct penalties, and neither side is opponent- or deployment-adjusted. Nothing here is priced in goals.

Observed values reflect the active rink filters; modeled values are fixed at their full-season fit.

On-ice numbers pair the regular-season shot set with shift-chart membership; skaters and goalies under the display floors are fit but not shown. Modeled rows come from the value artifact keyed to RAPM fit rapm__0cd6d075 on nested_structure__nested_structure_xg__d2ec2662 (the joint-xg structural baseline), with ratings from joint__baseline_xg__f3e3111e (as of 2026-06-14) — separate surfaces from the box-score xG model badged in the footer.
