Vladislav Kolyachonok

A left-shot depth defenceman with 35 games of NHL work and a minus-12 to explain them.

This Season So Far

The 2025-26 season has not started. The empty row above is his, and both it and this paragraph fill in on their own from the morning after he first plays: what he has done, what it is worth against his own last season, and the run he is on when the two disagree.

Last Season

2 goals and 5 assists in 35 games for 7 points, minus-12, on 13:01 a night with Utah.

The minus-12 in 35 games is the worst rate on this roster by a wide margin, and it came in third-pair minutes on a club that was not good. Some of that is the club. Not all of it.

The Finesse Game

The skating is fine and the puck moves quickly enough. He can join a rush without being a liability and he does not stall a breakout, which is most of what a seventh defenceman is asked for.

20 shots in 35 games and 2 goals. There is no offensive game to project and no power-play value; what he is competing for is the last defence spot on a roster, against men who defend better.

The Physical Game

6-2 and 198, and neither heavy nor especially willing. He does not clear a net front and he loses more board battles than he wins against NHL forwards.

10 penalty minutes in 35 games. He is not undisciplined; he is simply not often in a position where a penalty is the alternative.

The Intangibles

A second-round pick, three organisations by 24, and a career spent on the boundary between the two leagues.

The honest projection is an American League defenceman who fills in for injuries, and Dallas signed him as exactly that. Anything more would be a surprise.

What kind of player

The searchable half of the report. The first group is computed from the season's own data; the rest are read out of the prose above, and each one carries the sentence that produced it. A subject the report never raised is simply absent.

a strengthread out of the prose, and claimed
he lacks itraised, and he does not have it

Each computed tag also says how well its measure holds up from one season to the next, because a tag describes a season that has finished and a reader will assume it predicts the one coming. Some do and some do not, and the gap is wide: five-on-five workload repeats well, scoring late does not repeat at all.

The numbers underneath

On the ice

Five-on-five, 2024-25 · 442 minutes

Expected goals: 51.4%; 66th pct
Shot attempts: 50.4%; 57th pct

Goals while he was on the ice: 13 for, 24 against. Expected: 18.1 and 17.1.

The eye and the numbers

Hindsight

Report

7th

Numbers

66th

The numbers rank him 59 points above where the report does. It was written for a back edition, with the seasons that followed already known. Neither the agreement nor the gap says anything about the eye, and this report is excluded from the club-level comparison for the same reason. Why the numbers land there sets out the club he did it on, the minutes he played and the men he played them with.

Both bars are percentiles among the 637 skaters in this edition with a report and enough ice time. The report bar ranks the mean of the grades above — 62 on their own scale — against every other report's mean. The numbers bar ranks his share of expected goals. A gap is a disagreement about where he belongs, not two scales talking past each other.

Tracked

NHL Edge, 2024-25 · 35 games

Top speed: 21.4 mph; 38th pct
Bursts over 20 mph: 0.77 a game
Distance: 1.94 miles a game
Hardest shot: 76.9 mph; 6th pct

A top speed is a season's best, and a man who takes more shifts gets more tries at one; the percentile is the feed's own, against every skater, and says less between a top-pair defenceman and a fourth-line wing than it does between two men in the same job. The counts are shown per game for the same reason.

Usual linemates

2024-25 with UTA · 279 minutes at five-on-five

Juuso Välimäkioff the roster34%
Ian Cole20%
Robert Bortuzzooff the roster14%

Share of his five-on-five ice time spent alongside each player, measured from shift charts. Special teams are excluded: a power-play unit is not a line.

Why the numbers land there

Five-on-five, 2024-25

The club: PIT took 49.0% of the expected goals as a club. His own share is 51.4% — 2.4 above the club he did it on.
The role: 442 minutes at five-on-five — 13th percentile in ice time.

With and without

Teammate	Together	Him apart	Mate apart
Juuso Välimäki	58.0%	49.5%	50.4%
Logan Cooley	46.7%	52.7%	49.1%
Dylan Guenther	46.0%	52.7%	50.2%

58.0% together, 49.5% for him apart and 50.4% for Välimäki apart. Both were worse apart, so whatever the two of them had together was doing real work.

Expected-goal share while both were on the ice, and for each man in the minutes he played without the other. Apart is the pair subtracted from his own totals. It does not settle who was carrying whom — apart from each other, both were still playing with somebody — but it does say whether the share travelled when the pairing broke up.

Where he shoots from

goal on goal missed

31 unblocked shots in 2024-25, 2 of them goals. His median goal came from 60 feet. 13% of his shots came from inside twenty feet, 71% from beyond forty.
