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 Monday 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 who can chip in at both ends of the ice. Tanev notched career highs in goals (14) and assists (15) last season, and will give the Penguins options as they try to recalibrate themselves after getting swept in the first round of the playoffs by the New York Islanders.

“He’s a guy that when he’s playing, makes our team harder to play against,” Rutherford said.

Tanev also fits the profile of what Rutherford was looking for following an uninspiring season in which Pittsburgh struggled to find a specific identity. Rutherford promised change in the aftermath and there has been a flurry of moves in recent days.

The Penguins sent productive but temperamental forward Phil Kessel to Arizona in exchange for forward Alex Galchenyuk, shipped defenseman Olli Maatta to Chicago for forward Dominik Kahun, and signed defenseman David Warsofsky and forward Andrew Agozzino to two-way contracts shortly after landing Tanev.

“We’ve changed the makeup of our team,” Rutherford said. “And now it’s training camp and a time where the coach will have to work hard to bring it all together.”

Tanev will provide the Penguins with some flexibility, though he is likely best suited for a bottom-six role in an effort to give Pittsburgh more scoring punch throughout the lineup, an issue at times last season as Pittsburgh relied heavily on the top line anchored by Sidney Crosby and Jake Guentzel and one of the league’s top power plays to get things done offensively. Rutherford began the offseason with a mandate to make Pittsburgh more responsible defensively while also creating a lineup that can provide more punch top to bottom.

“It gets us back to where we were in 2016-17 where a coach can roll those lines and maybe play those lines a little more on an even minutes basis,” Rutherford said.

He downplayed the length of Tanev’s deal, chalking it up to the cost of doing business.
