Lalonde has been behind the bench during Tampa Bay's last three Cup runs, albeit 2021-2022, being beaten by the Colorado Avalanche. He's also had success in the ECHL coaching the Toledo Walleye, during their affiliation with the Detroit Red Wings to a 50-15-5-2 and winning the Brabham Cup during the regular season.
He's also been successful in the AHL with the Iowa Wild, 69-58-17-8 all the while posting records for wins, home wins, road wins, fewest losses and total points in a season.
Yzerman wanted a coach who would shore up the team defensively, as under Blashill they had regressed, so the choice checks out, as Lalonde's record is impressive.
