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 695 ranked skaters whose contract is known. How value is worked out.

The contract

Signed by the Vegas Golden Knights on Jun 24, 2019, as an extension of the contract he was on: 8 years and $47.2M, beginning in 2019-20. It runs through 2026-27, with 4 seasons left after this one, and he is then an unrestricted free agent.

Each season of the contract, with this one marked. The cap hit is the same every year; what he is paid is not. The pay is as written when the contract was recorded in October 2024, so a later change, such as the rise in the lowest salary for 2026-27, is not shown.

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 2022-23 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. Before 2023-24 the NHL timed events less exactly, and differently from rink to rink, so expected goals for this season are rougher than for recent ones.

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. Before 2023-24 the NHL timed events less exactly, and differently from rink to rink, so expected goals for this season are rougher than for recent ones.
