The St. Louis Blues have finalized their coaching staff for the 2026-27 NHL season, hiring Greg Cronin and Vaclav “Vinny” Prospal as assistant coaches and signing Jeremy Coupal as assistant coach – video. According to an official team announcement, these moves complete the staff under head coach Jim Montgomery, while Elliott Mondou has been promoted to assistant to the general manager.
How does the new coaching staff impact team strategy?
Head coach Jim Montgomery stated that the staff additions are designed to balance specialized technical instruction with veteran experience. According to Montgomery, Greg Cronin will focus on defensive structures and the penalty kill, utilizing his extensive head coaching background from the NHL’s Anaheim Ducks and the AHL. Conversely, Montgomery noted that Vaclav Prospal is expected to leverage his 1,108-game NHL playing career to mentor the forward group, specifically targeting improvements in power-play efficiency and five-on-five creativity.

Vaclav Prospal ranks seventh all-time in points among Czechia-born NHL players, trailing only legends like Jaromir Jagr and Patrik Elias.
What is the significance of the shift toward video-integrated coaching?
The appointment of Jeremy Coupal as assistant coach – video highlights a growing trend in the NHL where video analysis is elevated to a formal coaching designation rather than just a support role. Coupal brings extensive experience from the Edmonton Oilers and Nashville Predators, alongside a stint with Team Canada. By integrating video analysis directly into the coaching structure, the Blues appear to be prioritizing data-driven tactical adjustments, a practice that has become standard for teams looking to optimize player performance in real-time.
How do these hires compare to previous organizational structures?
The Blues’ 2026-27 staff represents a departure from traditional reliance on long-term internal promotions, opting instead for a mix of external veteran coaches and specialized technical staff. While the team retained David Alexander as director of goaltending and Ryan Stacy as video coordinator, the addition of Cronin—who brings 40 years of experience—contrasts with the promotion of Mondou, a younger staffer moving into a management-adjacent role. This dual approach suggests the front office is balancing the need for proven tactical systems with the development of internal administrative talent.
Pro Tip: The Power of Specialization
Modern NHL rosters often benefit when assistant coaches are clearly segmented by discipline. By assigning specific mandates—Cronin for defense and Prospal for offense—the Blues are reducing ambiguity in player instruction.
