Rosie Couture had an eight-year NHL career that began in 1928-29 with the Chicago Blackhawks. That year, he scored a goal and four points in 43 games. He greatly improved his offensive output the following season, scoring eight goals and eight assists.
In 1930-31, Couture established himself as one of the team leaders in the Chicago dressing room and enjoyed another good season, scoring eight goals and eleven assists for 19 points. In 1932-33, he hit the ten-goal plateau, the only time he would do so in his NHL career. Couture played with the Blackhawks through the 1934-35 season.
Couture played on two Stanley Cup winning teams in Chicago, in 1934 and again in 1938 where they faced the Detroit Red Wings in a best-of-five series final. Detroit was the definite favourite, having finished the 1933-34 season in first place in the American League. The Blackhawks had not won a game in Detroit in four years going into the finals.
Game one was in Detroit on April 3, 1934. The Blackhawks scored the first goal of the game before the Wings tied it, sending the contest into overtime. The teams played a scoreless overtime period, but Paul Thompson was able to hit the back of the net in double overtime, giving the Hawks a 2-1 victory and a 1-0 lead in the series. Game two was also held in Detroit, two nights later. Couture, who scored only five goals during the season, scored twice for the Blackhawks as Chicago scored a 4-1 win to take a 2-0 series lead back to the Windy City. The Hawks went on to win the series in four games.
Couture finished his career with 48 goals and 56 assists for 104 points.
