"Jordan is an elite two-way player who possesses a rare combination of speed, size, scoring ability and defensive responsibility," said Hurricanes GM Jim Rutherford. "For his young age, he has a wealth of NHL experience, including winning the Stanley Cup with Pittsburgh in 2009. And he is obviously a natural fit for our team in joining our captain, his older brother Eric.
"We want to thank Brandon Sutter for his time in Carolina. He has been a very good player for our team, and we wish both Brandon and Brian the best as their careers continue."
In six NHL seasons with Pittsburgh, Staal has scored 120 goals, earned 128 assists and posted a plus-53 plus/minus rating in 431 regular-season games. He captured the Stanley Cup with Pittsburgh in 2009.
The Penguins selected Staal in the first round, second overall, in the 2006 NHL Entry Draft.
Sutter, 23, recently completed his fourth NHL season with the Hurricanes, tallying 17 goals and 32 points while appearing in all 82 regular-season contests. He ranked fourth (tied) in the NHL with a career-high three shorthanded goals.
Sutter has appeared in 286 career regular-season games with Carolina, totaling 53 goals, 54 assists, 107 points and a plus-8 rating. Originally Carolina's first-round draft pick in 2007 (11th overall), Sutter's best season came in 2009-10 when he registered 21 goals and 40 points in 72 regular-season games.
Dumoulin, 20, played the past three seasons with reigning NCAA national champion Boston College Eagles. Carolina signed the 6-foot-4, 210-pound Dumoulin to a three-year entry-level contract earlier this spring.
