7 NHL Stars Who Underperformed in 2025: Age, Injuries & Line Changes
Why NHL Stars Like Duchene, Stone Struggled in 2025

The 2025 NHL season delivered its share of surprises, but for a group of high-profile players, it was a story of unmet expectations. Fans and experts had anticipated strong performances from established stars and steady leadership from veterans, but a combination of factors led to a noticeable dip in output for several key names.

The Core Reasons Behind the 2025 Slump

Hockey is unpredictable, and the 2025 campaign proved that even the most skilled athletes can struggle. The primary culprits were a mix of aging curves, significant line-up alterations, and the simple law of averages catching up to previously hot streaks. For younger players who had set new personal benchmarks, maintaining that elite level proved incredibly challenging. For veterans, the physical toll of long NHL careers began to show, compounded by injuries and adapting to new team strategies and linemates. Analysts from ESPN and NHL.com consistently highlighted these trends throughout the year, noting that the dip in production was often due to circumstances beyond a player's direct control.

Player-by-Player Breakdown of Key Struggles

Ryan Donato, after a breakout 62-point season with Chicago playing alongside Connor Bedard that earned him a four-year, $4 million contract, faced a different reality. A move down to the third line at the season's start significantly eroded his scoring opportunities.

Matt Duchene, at 34, saw his path to another 82-point season blocked. The loss of his effective linemate, Mason Marchment, was a major blow. Furthermore, his reliance on an unsustainably high shooting percentage was a statistical red flag that eventually corrected itself.

Morgan Geekie of the Boston Bruins, coming off a personal best of 57 points, was unlikely to sustain the remarkable 22% shooting rate that fueled his prior success.

Brandon Hagel, 28, remained a productive scorer but a demotion to the second line naturally led to a reduction in his overall offensive output compared to previous campaigns.

In goal, Darcy Kuemper (35) battled the dual challenges of age and a struggling defensive squad in front of him, resulting in performance metrics far below his Vezina-winning standards.

Aliaksei Protas of the Washington Capitals, despite offseason skating improvements, found replicating his surprise 30-goal season an immense task in the following year.

Finally, Vegas Golden Knights' cornerstone Mark Stone entered his mid-thirties. His physically demanding, two-way style of play, combined with adjustments to a new line, slightly but noticeably curtailed his offensive contributions.

Realistic Expectations for the Future

It is crucial to note that all seven players remain vital assets to their respective teams. Their 2025 struggles do not diminish their skill or value. However, the converging factors of age, lineup instability, and regression from statistically fortunate seasons made it exceptionally difficult for them to repeat their stellar 2024-25 performances.

Fans should anticipate continued good, but perhaps not elite, contributions from these stars. Managing expectations for the 2025-26 NHL season is advised, as the natural evolution of a player's career and team dynamics continue to shape their on-ice production.
