Contract

$863KCap hitends in 2026, then RFA

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. He rated at or below a spare-part player, so there is no cost per goal to show.

The contract

Signed by the Detroit Red Wings on Aug 14, 2021, as an entry-level contract: 3 years and $5.325M, beginning in 2023-24. It runs through 2025-26, with 1 season left after this one, and he is then a restricted free agent.

Season Cap hit Base salary Signing bonus Performance bonuses Paid in all Clause
2023-24 $863K $833K $93K $850K $925K
2024-25 $863K $833K $0 $850K $833K
2025-26 $863K $833K $0 $850K $833K

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 2024-25 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 saved for his team, compared with a spare-part goalie facing the same shots. A goalie's season is about one-third the goalie and two-thirds chance, so read one year lightly. He has played fewer than 20 games, too few to be ranked.

Shots faced

Expected goals adds up how likely each shot he faced was to go in, judged by where it came from, what kind of shot it was and whether it was a rebound. A goalie who lets in fewer than that has saved goals above expected. Only shots taken while he was in net count, and the league's goalies as a whole come out at zero. What these numbers mean
