His cap hit for the whole season, set against what he did in the regular season. Lower is better value. In a season still being played the cost per point starts high and falls as the games add up. Value is coloured by where it ranks among the 715 ranked skaters whose contract is known. How value is worked out.

The contract

Signed by the Utah Mammoth on Jun 26, 2025, as an extension of the contract he was on: 5 years and $38.5M, beginning in 2025-26. It runs through 2029-30, with 4 seasons left after this one.

Season Cap hit
2025-26 $7.7M

2027-28 $7.7M
2028-29 $7.7M
2029-30 $7.7M

Each season left on the contract. Only its cap hit and its end are known: how the pay is split by season, and any signing bonus, are not.

Every contract on record for him, newest first, with the team that signed him to it and the day it was signed. The one covering 2025-26 is marked. 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. A playoff run is too short to rank anyone on.

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.

Chances and finishing
