Wranglers hire John Dean as assistant coach under Brett Sutter

The Calgary Wranglers added a coach with a proven development résumé and a direct link to some of the organization’s most familiar young faces. John Dean was hired as an assistant coach under Brett Sutter, giving Calgary a staff that now includes David Liffiton, Mackenzie Skapski and Chandler Biggar, with the move aimed at sharpening the club’s next wave of talent as the 2026-27 season approaches.

Dean arrives from the Ontario Hockey League after spending the past eight seasons as head coach of the Sault Ste. Marie Greyhounds. In that span, he became the longest-serving head coach in franchise history and posted a 247-178-49 record over 472 games behind the bench, a run that underscores both consistency and player development in one of Canada’s most watched junior leagues.

That development background matters in Calgary. Dean coached current Wranglers defenceman Etienne Morin, along with forwards Rory Kerins and Morgan Frost, during his time in Sault Ste. Marie. For an AHL club tasked with feeding the Calgary Flames pipeline, those are the kinds of relationships that can speed up the transition from junior hockey or first-year pro to NHL-ready habits.

Dean also brings international experience, having represented Canada at the U17 and U18 levels and winning medals at both tournaments. That pedigree should fit neatly with a Wranglers roster that relies on teaching as much as tactics, especially when young players are learning how to manage puck decisions, penalty kills and pace over a long American Hockey League season.

The staffing change also marks another step in Brett Sutter’s first major build behind the bench. Sutter was named Wranglers head coach on June 20, 2025, after beginning his coaching career in 2024-25 as an assistant under Trent Cull and later interim head coach Joe Cirella. In his first season, Calgary went 37-28-4-3 and finished fifth in the Pacific Division, a respectable debut that earned Sutter a spot on Calgary’s coaching staff at the 2025 AHL All-Star Classic.

Cirella did not return to the Wranglers after the 2025-26 season, and Dean’s arrival gives Sutter another veteran voice with a record of getting junior players to the next level. For Calgary, the hire is about more than filling a seat on the bench. It points to a clearer development lane for prospects such as Morin and Kerins, and to a staff built to make the Flames’ pipeline harder to miss.
