Since his team's 2011 Stanley Cup championship run, Boston Bruins general manager Peter Chiarelli has stressed the need to keep the team's core group together, actively signing many key players to extensions. One of the biggest pieces of that puzzle, head coach Claude Julien, is the latest to be signed long term. The Bruins officially announced Tuesday they have signed the former Jack Adams trophy winner to a multiyear contract extension. Per team policy, terms of the contract were not disclosed. In addition to the Stanley Cup, the Bruins have won three Northeast Division titles during Julien's five-year reign. He is the fifth longest tenured head coach in the NHL after Buffalo's Lindy Ruff, Nashville's Barry Trotz, Detroit's Mike Babcock and Vancouver's Alain Vigneault. "As a manager, I know when I want to add a player to our mix, I know and have complete confidence in Claude and his staff (that) that player will become better," Chiarelli said. "It helps me as a manager, and when you look at the progression of players we've had in this lineup and have made this team better, it's a testament to Claude and his staff. That makes my job a lot easier." Read more: http://espn.go.com/boston/nhl/story...ude-julien-says-extremely-happy-remain-boston
