An extension is signed while the contract before it is still running, often a year ahead. A row with no team or date is a contract known only by its cap hit, most often one signed since October 2024.

The goals he added to his team's goal difference, compared with a spare-part player given the same ice time. Each part is measured against the league, so zero is an average skater. A full season is about two-thirds the player and one-third chance. He has played fewer than 20 games, too few to be ranked.

These are left plain: he has not been on the ice enough to be ranked. That takes at least 200 shot attempts with him out there, about six or seven games, and a quarter of what the busiest skater has. Over a game or two these numbers are mostly chance.

The two shares are coloured as above, against the league's lines that played a fair amount together. Hover over one for its percentile.

Chances and finishing

Expected goals adds up how likely each of his shots was to go in, judged by where it came from, what kind of shot it was and whether it was a rebound. All situations, leaving out shots at an empty net.
