The 25-year-old Dumoulin has played in every playoff game the Penguins played the last two seasons (49 games), helping Pittsburgh win back-to-back Stanley Cups titles.
He had 14 points (three goals, 11 assists) this postseason and averaged 21.59 minutes of ice time, the most of any Penguins player in the playoffs. His plus-9 in the postseason was best among the Penguins’ defensemen.
According to CapFriendly.com, the Penguins now have $6.28 million in projected cap space, but they still have to sign restricted free agent Conor Sheary. The 25-year-old forward had 23 goals and 53 points last season, often skating on Sidney Crosby‘s line. But his production fell in the postseason.
