PITTSBURGH (AP) – Pittsburgh Penguins general manager Jim Rutherford began his team’s longer-than-expected offseason by talking about the need for a culture change. Two months later, the process is finally underway. The Penguins opened free agency by signing versatile forward Brandon Tanev to a six-year deal worth $3.5 million annually. The 27-year-old Tanev spent the first four seasons of his career with Winnipeg, earning a reputation as a quality penalty killer and a hard-working two-way player.
