Did the goals match the chances?

Goals against expected goals

Cumulative goals (solid) and individual xG (dashed) through the season. The gap is finishing: above the dashed line, the player scored more than an average shooter would from the same chances.

Speed and tracking

From the NHL's EDGE tracking system (2021–22 on): skating speed, shot speed, distance and zone time, for the selected seasons and then every tracked season, to show improvement or decline.

Tracking data (NHL EDGE)

Values from the NHL's puck and player tracking, with the NHL's own league percentile for each. Missing values mean the player wasn't tracked enough.

Tracking, season by season

Each season against the other defencemen that season with 20+ games. A season in progress appears once half its games are played, as provisional: season bests only grow. Bursts and distance are per 60 minutes of ice time, so seasons with fewer games still compare. Percentiles are on these rates, so they can differ from the NHL's, which are on season totals.
