“We feel that the time is right for Todd to lead our hockey club,” general manger Brian MacLellan said in a statement. “Based on his coaching experience, communication abilities, his approach to the game and the respect he commands in our locker room, we feel that Todd has earned this opportunity.
“Todd has played an integral part in helping lead our team to the Stanley Cup championship and we feel his appointment as head coach will enable our organization to transition seamlessly into next season and beyond.”
The Capitals had been grooming Reirden, who has been responsible for coaching the team’s defensemen, for a head-coaching gig. He wasn’t allowed to interview with other teams last summer.
In Reirden’s four seasons with the team, the Capitals have ranked second in the NHL with a 2.45 goals-against average. They led the league last season with a franchise-record 2.16.
Prior to joining the Capitals in 2014, Reirden spent four seasons as an assistant coach with the Pittsburgh Penguins, where he helped the team capture the Stanley Cup in 2009.
Trotz is just the fifth coach in the last 40 years not to return to a Stanley Cup winner.
