Blues Expand Coaching Staff with Defensive Veteran, Offensive Specialist, and Video Analyst

The St. Louis Blues have completed their assistant coaching roster for the 2026‑27 season, officially adding Greg Cronin, Vaclav “Vinny” Prospal, and Jeremy Coupal to Jim Montgomery’s bench. Elliott Mondou was also promoted to assistant general manager under Alexander Steen. The hires provide a mix of experience, offensive insight, and modern video expertise as the organization refines its structure heading into the new campaign.

These additions give the Blues a more specialized coaching setup, with each new member expected to handle distinct duties ranging from defensive systems to forward development and game preparation. The moves also reflect a league‑wide trend toward deeper, more segmented coaching staffs designed to support daily adjustments and long‑term player growth.

Cronin’s Track Record Behind the Bench

Cronin arrives in St. Louis with one of the most extensive coaching backgrounds in professional hockey. His career spans nearly four decades across the NHL, AHL, and NCAA, including a recent stint as head coach of the Anaheim Ducks from 2023 to 2025.

Known for his structured approach, Cronin has built a reputation for defensive responsibility, detail‑oriented systems, and disciplined play without the puck. Throughout his stops he has emphasized habits such as zone coverage, penalty killing, and defensive‑zone exits.

For the Blues, that skill set addresses a clear area of focus. The team has shown inconsistency in its defensive game in recent seasons, particularly in maintaining structure over full‑game performances. Cronin’s background suggests he will be tasked with reinforcing those habits and helping stabilize the team’s play in its own zone.

Beyond his NHL experience, Cronin has held multiple roles at the AHL and collegiate levels, including head‑coaching positions at Northeastern University and the University of Maine. This range provides a strong developmental foundation, especially valuable for a roster that includes younger players adjusting to full‑time NHL roles.

Prospal’s Offensive Mindset Joins the Staff

Prospal joins the Blues after three seasons as an assistant coach with the AHL’s Rochester Americans, where he helped guide a consistent playoff team while working closely with the club’s forward group. His transition to the NHL coaching ranks follows a lengthy playing career that spanned more than 1,100 games.

As a player, Prospal was known for his creativity, puck control, and ability to generate offense in tight areas. He also demonstrated strong hockey sense and adaptability, playing both centre and wing and contributing in multiple roles throughout his NHL tenure.

Those traits are expected to translate directly into his coaching responsibilities in St. Louis. Prospal will likely work closely with the Blues’ forwards, focusing on offensive‑zone structure, puck movement, and finishing plays. Special attention may be given to the power play, an area where the Blues have sought greater consistency and creativity in recent seasons.

His presence adds a different voice behind the bench, particularly for younger forwards who can benefit from a coach with direct experience producing offense at the NHL level. The organization is betting on his ability to bridge player instincts with structured systems.

Coupal Adds Video‑Driven Expertise

Coupal’s hiring reinforces the Blues’ investment in video analysis and game preparation. With experience in both the NHL and international hockey, he brings a modern approach to scouting, breakdowns, and behind‑the‑scenes preparation.

He previously worked with the Edmonton Oilers and Nashville Predators, two organizations known for integrating detailed video work into daily routines. More recently, he has been involved with Hockey Canada, gaining experience in international tournaments where rapid adjustments and opponent familiarity are critical.

In St. Louis, Coupal’s role will center on video breakdowns, opponent scouting, and supporting game planning throughout the season. His work will be especially important in preparing the team for matchups on short rest and assisting coaches with in‑game adjustments based on tactical shifts.

As the NHL continues to evolve, video coaching has become a key competitive advantage. Teams now rely heavily on rapid analysis between periods and even during games, making Coupal’s background a valuable addition to Montgomery’s staff.

A Staff Built on Defined Roles

Taken together, the hires reflect a clear strategy from the Blues: build a staff with specialized expertise rather than overlapping responsibilities. Cronin brings structure and defensive detail, Prospal adds offensive creativity and forward development, and Coupal strengthens analytical preparation and game planning.

The combination gives Montgomery a more versatile bench, particularly in adjusting to in‑game situations and managing player development over a long season. Each coach fills a specific need, allowing for more focused instruction and clearer communication with players.

As the Blues prepare for the 2026‑27 season, these additions signal an effort to modernize behind‑the‑bench operations while maintaining a strong foundation of experience. The success of the group will ultimately be measured by how effectively those roles translate into improved consistency and execution on the ice.
