2017-18 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. 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 691 ranked skaters whose contract is known. How value is worked out.

The contract

Signed by the New York Islanders on Jul 5, 2017, as an entry-level contract: 3 years and $2.775M, beginning in 2017-18. It runs through 2019-20, with 2 seasons left after this one.

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.

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 2017-18 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.

2017-18 analytics

Rating

Each number is coloured by where it ranks among the 240 ranked defencemen: green is in the top fifth and red the bottom fifth, with paler shades in between and amber for the middle. Hover over a tile for its percentile.

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, and the rank beside it is among defencemen. A full season is about two-thirds the player and one-third chance. Provisional: under 40 games it is more chance than player. 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.

On the ice

What happened at five-on-five while he was on the ice. What these numbers mean

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.

Who he played with

The pairs he spent the most time in at five-on-five, with the team's share of the shot attempts and expected goals, and the goals for and against, while they were out. The two shares are coloured as above, against the league's pairs that played a fair amount together. Hover over one for its percentile.

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.

Each bar shows the share of defencemen he is ahead of, among the 242 who played 300 minutes or more this season.
