Terry W. "Rosco" Ruskowski (born December 31, 1954 in Prince Albert, Saskatchewan) is a Canadian former National Hockey League centre, who played for the Chicago Black Hawks, Los Angeles Kings, Pittsburgh Penguins, and Minnesota North Stars. He is currently the head coach and general manager for the Quad City Mallards.
Previously, he played for the Houston Aeros and Winnipeg Jets of the WHA. Ruskowski's leadership on the ice was recognized with his tenure as captain of the Aeros, Blackhawks, Kings, and Penguins, the only player in major professional history to captain four clubs.
In 2001, he was named the head coach of the since disbanded Laredo Bucks in Laredo, Texas, which had been affiliated with the Central Hockey League. On March 18, 2009, Ruskowski secured his 500th coaching win, as the Bucks defeated the Texas Brahmas of Fort Worth, 4-3, in the Southern Conference playoffs.
In 2007, Ruskowski entered the final year of a four-year contract extension with the Bucks. Ruskowski told the Laredo Morning Times that his tenure was in the hands of Bucks chairman Glenn Hart, owner Julian "Kiki" DeAyala, and team president John Beckelhymer and that he had "full faith" that he will obtain his third contract with the club. Ruskowski's optimism paid off, for he was shortly thereafter given a "lifetime contract" as the coach of the Bucks.
