One week is enough to notice when reality starts to differ from preseason expectations, even if it is far too early to know whether those differences will last.

The first six days have already produced unexpected roles, unusual stat lines and a few genuinely interesting fantasy developments. The important part is separating early production from changes that may actually affect future value.

Here are the Week One surprises that matter most.

The league started fast

The first surprise was the scoring environment.

There were several high-scoring games immediately, with teams such as Colorado, Edmonton, Vancouver and Pittsburgh producing unusually large totals. That does not mean the NHL has suddenly entered a permanently higher-scoring era, but it does matter when interpreting individual starts.

A player opening with six points in four games looks different when his team has scored 19.

The points still count. The useful question is whether anything underneath them has changed.

Elias Pettersson looks more involved

Pettersson’s six points in Vancouver’s first four games were encouraging, but the more surprising number was his 18 hits.

That is not normally a major part of his fantasy profile.

Nobody should project that rate forward, but it is worth noting because it suggests a different level of physical involvement than we have usually seen from him. For a player whose consistency and engagement were questioned at times last season, that may be more interesting than the early point total itself.

If the scoring remains strong and the broader activity level stays elevated, Pettersson’s fantasy profile could become more complete than expected.

Paul Cotter suddenly has opportunity

Paul Cotter scoring four goals in four games was unexpected.

The more relevant development was that Vancouver also used him on the first power-play unit when Jake DeBrusk was unavailable.

Cotter already has value in physical categories. If Vancouver is willing to move him higher in the lineup when opportunities appear, he does not need anything close to his current scoring rate to become useful in deeper fantasy formats.

The goals will regress. The expanded role is worth monitoring.

Tristan Luneau was given the job immediately

Anaheim did not ease Tristan Luneau into the season.

After signing him to a long-term extension, the Ducks immediately gave him heavy minutes and PP1 responsibility. That is significant for fantasy because offensive defensemen are highly sensitive to deployment.

A talented defenseman playing 17 minutes with PP2 usage can remain marginal. The same player receiving 24-plus minutes and quarterbacking PP1 becomes a very different asset.

Luneau still has very limited NHL experience, but the opportunity is no longer theoretical.

Luca Cagnoni has PP1

The same applies to Luca Cagnoni in San Jose.

His early points were useful, but the important development is that he has been trusted on the Sharks’ first power-play unit while also receiving substantial minutes.

That matters because San Jose now has enough young offensive talent for its PP1 quarterback to become fantasy relevant even before he develops into a complete NHL defenseman.

Cagnoni will almost certainly have difficult stretches. Young defensemen usually do.

But the role is real enough to matter.

Colorado’s goalie hierarchy changed quickly

Mackenzie Blackwood starting Colorado’s first two games was one of the more important Week One developments.

Two starts are not enough to establish a season-long hierarchy, but starts are more informative than early save percentage. If Colorado begins leaning toward Blackwood rather than the more balanced split many expected, that creates significant fantasy value simply because of the environment around him.

Colorado should generate wins.

The goalie receiving most of those opportunities matters.

This can change again quickly, but the preseason assumption already deserves another look.

Porter Martone’s minutes are the concern

Porter Martone started without a point.

That is not particularly interesting after three games.

His 12:31 average ice time is.

Martone remains an excellent long-term prospect, but fantasy value in the current season depends on opportunity. If the role stays around 12–13 minutes without significant power-play exposure, his redraft ceiling is much lower than his talent alone would suggest.

The important question is therefore not when his first point arrives.

It is when the minutes arrive.

Pittsburgh may contain more fantasy depth than expected

Pittsburgh’s offensive start was probably too strong to take literally, particularly after scoring seven in the opener.

What is more interesting is that some less obvious players have received useful roles quickly.

Tommy Novak has seen PP1 usage, while players outside the established veteran core have been given legitimate offensive opportunity.

The Penguins do not need to remain one of the league’s highest-scoring teams for this to matter. If those roles persist once the early scoring normalizes, there may be more fantasy depth in Pittsburgh than preseason expectations suggested.

Calgary may be a bigger problem for Dustin Wolf than expected

Calgary being weak was not surprising.

The extent of the opening struggles was.

That matters for Dustin Wolf because goalie fantasy value is heavily dependent on team environment. Wolf can play well individually and still lose value if Calgary consistently gives up too much, spends too much time defending and provides limited goal support.

His early numbers should not be taken literally.

The team context deserves more attention.

If Calgary remains materially worse than expected, the fantasy concern is not that Wolf suddenly became a bad goalie. It is that his path to wins and useful ratios becomes harder.

What actually changed our view?

After one week, very little should cause a major change in a full-season projection.

A few things do matter.

Luneau’s PP1 role matters. Cagnoni’s PP1 role matters. Blackwood receiving consecutive starts matters. Martone playing only 12:31 per game matters.

Pettersson’s physical involvement is worth watching, while Cotter’s expanded opportunity may add another dimension to an already useful category profile.

The large point totals are less convincing on their own.

That is probably the main lesson from Week One.

There is already enough information to change some assumptions.

There is not enough information to pretend that the season has revealed its answers.
