BOSTON (AP) -- Boston Bruins coach Bruce Cassidy has one more tool available this year as he tries to take the team from Stanley Cup finalist to NHL champion. Armed with a contract extension and an updated resume that includes an Eastern Conference championship, Cassidy is far removed from his days as the interim boss who failed in his first head coaching job and took over the Bruins in 2017. "We did lot of good things last year, but didn't reach our ultimate goal," Cassidy said at the opening of training camp Thursday, a day after signing a multiyear extension that eliminated the chance he would be a lame duck this season.
