Roy made the announcement Thursday through a public relations agency, two months before the start of the NHL regular season.
The Hall of Fame goaltender spent the past three seasons as coach and VP of hockey operations for the team that he led to two Stanley Cups as a player. Colorado made the playoffs in Roy's first year behind the bench and missed the past two.
Roy cited his vision and the organization's vision not being aligned and his lack of say in team decisions as reasons for stepping down. He says he remains on good terms with the Avalanche.
