Justin Carbonneau has already shown why the St. Louis Blues viewed him as a first-round talent. The 19-year-old forward has one of the most exciting offensive skill sets in the organization, highlighted by an impressive shot, shifty puck skills, and the ability to create opportunities for himself and his teammates. The next challenge will be proving he can bring those same qualities to the professional level.
After being selected 19th overall in the 2025 NHL Draft, Carbonneau enters the 2026-27 season as one of the Blues’ most intriguing prospects. He is expected to begin with the Springfield Thunderbirds in the American Hockey League (AHL), where he will get his first full opportunity to adjust to the speed, physicality, and consistency required at the professional level. However, the path to an NHL roster spot will not be easy.
The Blues have built a much deeper organization, especially at forward, and that means prospects will have to beat out established players on the roster. St. Louis is no longer in a position where young players are called up simply because there is an opening. They need to prove they are the best option available.
For Carbonneau, that likely means becoming one of the AHL’s most productive offensive players and forcing the Blues to consider whether he is ready for the next step.
The Offensive Talent Is There
The biggest reason Carbonneau became a first-round pick was his ability to produce offense.
During the 2025-26 season with the Baie-Comeau Drakkar of the Quebec Maritimes Junior Hockey League (QMJHL), Carbonneau recorded 51 goals and 29 assists for 80 points in 60 games. His production showcased the combination of scoring ability and playmaking that made him one of the top offensive players in junior hockey. His shot is the first thing that stands out.
Carbonneau has a quick and accurate release that allows him to beat goaltenders before they have time to react. Whether it is from the top of the circle on the power play or in transition, he has the ability to create goals without needing much time or space. That skill could eventually make him a dangerous NHL scoring threat.

What separates Carbonneau from a pure goal scorer, however, is his ability to create for others. He has strong offensive instincts and the vision to find teammates in scoring areas. He can draw defenders toward him, create openings, and make plays that lead to quality scoring chances.
That combination of shooting and playmaking gives him the potential to become a top-six forward at the NHL level. The challenge is proving he can consistently use those tools against professional competition.
A Small First Taste of Professional Hockey
Carbonneau has already received a small taste of what life in the AHL will be like. Following the conclusion of his junior season, he joined the Thunderbirds during their Calder Cup Playoff run. It allowed him to experience a short taste of professional hockey before entering his first full season, but the transition was understandably difficult. Carbonneau appeared in three playoff games and finished without recording a point.
The numbers were not necessarily a reflection of his ability. He was entering one of the most intense parts of the hockey calendar against older players who had years of professional experience. AHL playoff hockey is a significant adjustment for young players because every mistake is magnified and there is far less time and space compared to junior hockey. Still, those three games provided valuable experience.
Carbonneau was able to see the pace of professional hockey, understand the physical demands, and get a glimpse of what he will need to handle throughout a full AHL season. The difference this year is that he will have an entire schedule to adjust and prove he can consistently impact games.
A strong start with Springfield could go a long way toward accelerating his development.
Fighting Through the Depth Chart
The biggest challenge facing Carbonneau is not a lack of talent. It is the amount of competition within the organization.
In Springfield, Carbonneau will be competing with other prospects looking to establish themselves, while also battling experienced AHL players for top-line minutes and special teams opportunities. If he wants to maximize his chances of earning an NHL call-up, he will need to quickly prove he belongs in an offensive role. That means producing consistently.
The Blues will not need Carbonneau to simply survive his first professional season. They need to see signs that he is becoming one of the most dangerous players in the AHL. That includes putting up points, becoming a reliable power-play option, and showing that he can drive offense even when opponents are focused on stopping him.

The NHL competition will be even tougher. St. Louis already has several young forwards who have established themselves at the NHL level, including Dylan Holloway, Dalibor Dvorsky and Jimmy Snuggerud, who are all expected to play very important roles moving forward. Along with established veterans and other players competing for lineup spots, Carbonneau will have to overcome a crowded depth chart to earn his opportunity. Even injuries at the NHL level may not immediately open the door, as the Blues will prioritize players they believe are most prepared to contribute.
Even if he is producing at a high level in Springfield, another player with more NHL experience could still receive the first look. Carbonneau will have to make it difficult for the Blues to overlook him.
Earning the Blues’ Trust
Offensive talent is what made Carbonneau a first-round pick, but becoming an NHL regular will require more than scoring goals.
The Blues will want to see him continue improving defensively, managing the puck under pressure, and becoming more reliable away from the offensive side of the game. NHL coaches need to trust young players in all situations, not just when they have the puck on their stick.
If Carbonneau can combine his elite offensive ability with a more complete game, his chances of earning a chance will increase significantly. The Blues have shown they are willing to reward young players who prove they are ready. However, with the organization’s depth improving, those opportunities are becoming harder to earn.
Carbonneau has the skill set to become an NHL player. His shot and playmaking ability give him a foundation that few prospects possess. Now, he has to prove he can dominate against professionals.
A standout season in the AHL would not only continue his development but also put him near the top of the list when the Blues need reinforcements. If he can consistently produce, showcase the offensive ability that made him a first-round selection, and continue rounding out his game, St. Louis may have a difficult decision to make.
For Carbonneau, the AHL is his opportunity to show he belongs, but he needs to become one of the league’s most impactful young players and force the Blues to consider him for an NHL role.
