​Can an NHL duo be too good? Throughout hockey history, the NHL has seen legendary duos like Wayne Gretzky and Jari Kurri, Mario Lemieux and Jaromir Jagr, Alex Ovechkin and Nicklas Backstrom, and Henrik and Daniel Sedin. Eventually, those partnerships dissolved or, in the Sedins’ case, retired together. A more recent pairing that raised questions about staying power is Kirill Kaprizov and Mats Zuccarello. Since Kaprizov’s move from the KHL to the NHL, Zuccarello has been his trusted linemate. The Russian and Norwegian stars appeared to have a near-telepathic connection, but a recent report suggests their chemistry may have been more about each other than about the rest of the team. In Elliotte Friedman’s 32 Thoughts podcast, he noted that one factor behind the split between Zuccarello and the Minnesota Wild was that the wingers were so focused on one another that they turned the game into a 2-on-5 situation rather than a full five-man cycle.
Offensively, the partnership thrived. Kaprizov has averaged 84 points per season since entering the NHL, a figure that encompasses a shortened rookie year and a 41-game campaign in 2024-25. Zuccarello has averaged 58 points per season since Kaprizov arrived in Minnesota. Yet the Wild’s front office and coaching staff ultimately believed the duo’s dynamic needed redefining, leading to Zuccarello’s decision to test free agency and sign a one-year contract with the Los Angeles Kings.
With that report in mind, the conversation shifts to three NHL duos who could be headed down a similar path, where their on-ice synergy might threaten broader team balance. Take Macklin Celebrini and Will Smith, whose bond off the ice is widely discussed and whose on-ice impact has been significant for the San Jose Sharks. There are early warning signs, however. In their rookie seasons (2024-25), Smith experienced scoring struggles. While part of this could be attributed to the Sharks’ cautious approach in integrating him into the NHL, his production began to rise when teamed with Celebrini. The pattern continued in 2025-26: Celebrini’s scoring pace remained strong whether Smith was in the lineup or not, and when Smith was separated from Celebrini, his performance appeared flatter. It’s far too soon to conclude that Celebrini and Smith will become inseparable to the point of hindering Smith’s development, but history provides a cautionary tale. The narrative of one dazzling duo overshadowing the rest of a player’s game is familiar, with high-profile examples such as Auston Matthews and Mitch Marner illustrating the risks of over-attached chemistry.
Similarly, the pairing of Cale Makar and Devon Toews has looked like a fixture in the Avalanche defense since they were first paired. Their compatibility is a reminder that strong duos can elevate a team’s performance, especially on the back end where trust and communication matter as much as raw talent. The challenge for any organization is balancing the benefits of a combustible partnership with the need for versatility across the lineup. In the modern NHL, where teams pursue dynamic, high-scoring duos, front offices must weigh the allure of a pairing that dominates zones and chemistry against the potential for becoming too albumen-contained—where one player’s success depends too heavily on the other.
Ultimately, the question remains: can a duo be too good? There is no absolute answer. A pair can drive a team to unprecedented heights with creative execution, seamless reads, and a shared vision. But there are tangible risks: over-reliance on a single pairing can limit line variety, endurance, and the ability to adapt to different opponents. As Kaprizov and Zuccarello’s chapter demonstrates, even historically prolific partnerships may reach a point where executive staff decide that a change is necessary to preserve long-term balance and growth across the roster.
In the end, the NHL’s history is full of iconic duos who left an indelible mark on the game. Whether a current or future pair proves to be too good to separate depends on how well teams manage the delicate balance between exploiting elite chemistry and cultivating depth, versatility, and the ability for every line to contribute in a variety of ways.
