Logan Mailloux Has One Season to Prove His Future With Blues – The Hockey Writers – St Louis Blues

Logan Mailloux enters the 2026-27 season with a final opportunity to prove he can become a long-term piece for the St. Louis Blues. The 23-year-old defenseman recently signed a one-year, one-way contract worth $850,000, giving him another season to show the organization that he can turn his potential into consistent NHL play.

A one-year agreement was sensible for both sides. Mailloux is still young and has plenty of time to develop, but the Blues also need to determine whether he can become the type of defenseman they envisioned when they acquired him from the Montreal Canadiens. Rather than committing to him for several seasons, the Blues can use this campaign as a final evaluation period before deciding what his future should look like.

A First Season With Mixed Results

The Blues acquired Mailloux from the Canadiens on July 1, 2025, for forward Zack Bolduc. Both players were first-round selections in the 2021 NHL Draft, with Montreal selecting Mailloux 31st overall and the Blues taking Bolduc 17th.

Mailloux arrived with an impressive offensive resume. He recorded 12 goals and 21 assists in 63 games with the Laval Rocket during the 2024-25 American Hockey League (AHL) season, along with two goals and two assists in seven NHL games with Montreal. His offensive upside, size, and right-handed shot made him an appealing player for the Blues.

However, his first full NHL season produced modest results. Mailloux appeared in 67 games in 2025-26, recording five goals and eight assists, while finishing with a minus-10 rating. He averaged 16:46 of ice time per game and registered 93 hits, 56 blocked shots, and 48 penalty minutes.

Those statistics provide some context, but Mailloux’s evaluation should not revolve entirely around his production. The Blues already know he has offensive ability, and his previous AHL numbers demonstrated that. His next step is becoming a more dependable defenseman in all areas of the ice.

Mailloux’s Defense Must Take a Step Forward

Mailloux’s defensive game needs the most improvement, particularly his ability to defend the front of the net. His 6-foot-3 frame gives him the physical tools to make life difficult for opposing forwards, but he did not consistently use that size effectively around the crease last season.

Mailloux needs to become much stronger in those situations. He has to do a better job establishing position, tying up opposing forwards, and clearing players away from the goaltender. The Blues cannot afford to have a large defenseman who struggles to win physical battles in one of the most important areas of the defensive zone.

That development could ultimately matter more to his future than whether he scores 10 goals or 20 points. If Mailloux becomes a more reliable defender while maintaining his ability to move the puck and contribute offensively, the Blues could have a well-rounded defenseman who can take on a larger role.

There were encouraging signs that Mailloux can make those changes. His play improved as the 2025-26 season went along, and he became more productive during the final portion of the year. That improvement gives the Blues a reason to remain patient with him rather than making a decision based solely on his overall statistics.

Mailloux Has One Year to Prove His Future

Mailloux’s age is another important factor in the Blues’ decision-making. At 23, he still has considerable time to develop, particularly at a position where players often need more time to become reliable. His first full NHL season was valuable experience, and another year should give him a better understanding of the pace and physical demands required to succeed.

The Blues will nevertheless expect tangible progress. Mailloux cannot simply repeat the same performance and expect the organization to make a significant long-term commitment. He needs to show that he is learning from his mistakes, competing consistently, and becoming more effective in the defensive zone.

The one-year contract gives the Blues flexibility while putting some pressure on Mailloux to perform. If he takes a significant step forward, the Blues could keep him around beyond next season and potentially give him a larger role. His size and skill set could make him a valuable part of the defense corps if he can become more consistent.

If he does not improve, however, the organization will have to consider whether waiting for his potential is still worthwhile.

What Happens If Mailloux Struggles?

A trade could be one possibility if the Blues determine that Mailloux has reached a developmental plateau. His age, being a first-round pick, and offensive upside could still make him attractive to another team, particularly one willing to give him a different opportunity. The Blues are also not taking on significant financial risk with Mailloux making $850,000 this season.

The Blues could also re-sign Mailloux and send him to the AHL, although that appears unlikely if he establishes himself as a legitimate NHL regular this season. He has already shown he can produce at the AHL level, so sending him to the minors should only be considered if his defensive struggles continue, and the organization believes he needs more development time.

For now, the Blues are giving him another opportunity because they still see something worth developing. The expectation should not be that he suddenly becomes a star. Instead, St. Louis needs to see steady improvement, particularly around the net and in physical battles. If he becomes more dependable defensively while continuing to contribute offensively, this one-year contract could become the bridge toward a much longer future with the Blues.

If he fails to make those improvements, St. Louis may have to explore a trade or another developmental path before deciding that his potential is no longer enough.
