Background: Nieuwendyk was born September 10, 1966 in Oshawa, Ontario, and grew up in Whitby. He is the youngest of four children to Gordon and Joanne Nieuwendyk, who immigrated to Canada from the Netherlands in 1958. Gordon owned a car repair shop in Whitby. Joe grew up in a sporting family.
Context: The Stars immediately signed Nieuwendyk to a new deal worth US$11.3 million over five years. Bob Gainey, the team's general manager, hoped that the acquisition of Nieuwendyk would help the franchise, which had relocated from Minnesota three years previous, establish its place in Dallas. Nieuwendyk scored 14 goals and 32 points in 52 games with the Stars to finish the 1995-96 season.  Nieuwendyk improved to 30 goals in 1996-97 despite missing the first month of the season with fractured rib cartilage. A 39-goal season followed, but he was again sidelined by injury after appearing in only one game of the 1998 Stanley Cup playoffs. In the opening game of the Stars' first-round series against the San Jose Sharks, he suffered a torn ACL as a result of a check by Bryan Marchment. The injury required two knee surgeries to repair and six months to heal, which caused him to miss the beginning of the 1998-99 NHL season.  He finished the regular season with 28 goals and 55 points in 67 games, and added 11 goals and 10 assists in the 1999 Stanley Cup playoffs to help the Stars win the first Stanley Cup in their franchise history. Six of his playoff goals were game winners, and he was voted the winner of the Conn Smythe Trophy as most valuable player of the playoffs. Injuries again limited Nieuwendyk in 1999-2000. He missed ten games due to a bruised chest then suffered a separated shoulder a week after his return that kept him out of the lineup for several weeks. He played only 47 regular season games, but added 23 more in the playoffs as the Stars reached the 2000 Stanley Cup Finals. They lost the series in six games to the New Jersey Devils, however.  Nieuwendyk played in his 1,000th career game on January 20, 2002, against the Chicago Blackhawks. Two months later, on March 19, 2002, he was traded to the Devils, along with Jamie Langenbrunner, in exchange for Jason Arnott, Randy McKay and a first round selection in the 2002 NHL Entry Draft.
