Metro Prystai put in three full seasons with the Moose Jaw Canucks of the SJHL between 1944 and 1947. During that time he became a local sports icon, leading his team to three straight provincial championships plus a trip to the Memorial Cup finals. He also led his league in scoring for two of his three seasons with the Canucks. His fame reached its peak when his picture was hung in the window of Thatcher's hardware store on Main St.
Prystai joined the NHL in 1947 with the Chicago Blackhawks. He was excited to join fellow Saskatchewan natives Max and Doug Bentley. But Prystai lasted only three seasons with the Hawks when he was traded to the Detroit Red Wings. Feeling that Chicago was on the rise, he was sorry to leave until he realized the lineup he was joining and winning prospects awaiting him in the Motor City. There, he skated with Ted Lindsay and Gordie Howe. He then settled in for much of his time on the checking line with Marty Pavelich and Tony Leswick.
The most exciting event of his career came when, in 1952, the Wings swept the entire playoffs, winning all eight contests, four against Toronto and four against Montreal. Terry Sawchuk had four shutouts as the Wings never gave up a goal in their own rink. As for Prystai, he scored two goals and an assist in the final game.
By 1954-55, Prystai was given a return ticket to play in Chicago again. He plugged away in the Windy City for just over one season before he was hustled back to Detroit where he remained until his demotion to the minors in 1957-58. He rounded out his on-ice career with the Edmonton Flyers of the WHL later that year.
