2026-27 season totals
This player has no games in this season.
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 all of it: what the player has done so far, plus the games left at a rate taken from his last three seasons and this one. He rated at or below a spare-part player, so there is no cost per goal to show. Value is coloured by where it ranks among the 647 ranked skaters whose contract is known. How value is worked out.
The contract
Signed by the Utah Hockey Club on Jun 26, 2024, as an extension of the contract he was on: 3 years and $3M, beginning in 2024-25. It runs through 2026-27, so this is its last season, after which he is an unrestricted free agent.
| Season | Cap hit | Base salary | Signing bonus | Performance bonuses | Paid in all | Clause |
|---|---|---|---|---|---|---|
| 2024-25 | $1M | $1M | $0 | $1M | ||
| 2025-26 | $1M | $1M | $0 | $1M | ||
| 2026-27 | $1M | $1M | $0 | $1M |
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 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.
