The Avalanche has given coach Jared Bednar a one-year extension and the NHL’s youngest team intends to remain young, general manager Joe Sakic said Monday at his season-ending press conference at the Pepsi Center. Bednar, who led the Avs to a 47-point improvement and the club’s first playoff appearance in four years in his second year at the helm, is now under contract through the 2019-2020 season.
