The defenseman signed a five-year, $23 million contract with the NHL's newest team, who selected him in the 2021 NHL Expansion Draft on Wednesday.
Seattle had an exclusive window from July 18-21 to interview and sign pending free agents who were left unprotected in the expansion draft. The Dallas Stars left the 6-foot-7, 256-pound defenseman unprotected. He could have become an unrestricted free agent July 28 after coming off a three-year contract he signed with the Pittsburgh Penguins on July 12, 2018.
The 28-year-old Oleksiak scored 14 points (six goals, eight assists) in 56 games this past season for the Dallas Stars.
Oleksiak, Dallas' first-round pick in 2011, has scored 72 points (24 goals, 48 assists) in 369 career games and 10 points (six goals, four assists) in 43 playoff career games. He played his first six seasons with the Stars before he was traded to the Penguins on Dec. 19, 2017. He then played two seasons with Pittsburgh until the Stars re-acquired him Jan. 28, 2019.
Oleksiak had 14 assists in 58 games for the Steel from 2008-10. He's the highest drafted player in Steel history.
