2026-27 season totals

Contract

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. The season is still being played, so each rating is projected over the whole season: the games played so far, plus the games left at the rate of the last three seasons and this one. He rated at or below a spare-part player, so there is no cost per goal to show.

The contract

Signed by the Utah Mammoth on Jun 30, 2026, as an extension of the contract he was on: 2 years and $4M, beginning in 2026-27. It runs through 2027-28, with 1 season left after this one, and he is then a restricted free agent.

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.

Contracts he has signed

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 2026-27 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.

2026-27 analytics

Rating, projected over the full season

2026-27 is still being played, so these are a projection of his whole season, not a count so far: what he has done in 2 games (-0.2 goals above replacement), plus the 4 more he is taken to play, going by how much of his team's games he has played before, at a rate set by his last three seasons and this one. The more he plays, the more this season counts, and by the last game it is simply his season.

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. His projection rests on fewer than 20 games, counting the last three seasons, 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

Each bar shows the share of goalies he is ahead of, among the 0 who played at least a quarter as much as the busiest this season.

The goals he was expected to let in and the goals he did, as the season went on. When the allowed line runs below the expected line, he is saving more than his shots were worth.
