Balanced scoring, strong third periods -- such as this one against the Los Angeles Kings -- and the dependable goaltending of Tim Thomas have given the Boston Bruins reason enough to think they can successfully defend their Stanley Cup title. Milan Lucic and Chris Kelly scored less than 1½ minutes apart early in the third period to break open a tie game, Patrice Bergeron scored a short-handed goal and Thomas made 40 saves, leading the Bruins to a 4-2 victory over the Kings on Saturday night.
