Wensink is best remembered for his time with the Boston Bruins, where he teamed with
Terry O'Reilly and
Stan Jonathan as the team's
enforcers. On December 1, 1977, Wensink, after fighting
Alex Pirus of the
Minnesota North Stars, skated to the Minnesota bench and challenged the entire team, but no player responded. Wensink is also well known for the large
afro that he sported on the ice. In another scrap with
Bob Kelly, Wensink and Kelly were pulling at each other's hair. Besides his skill as a fighter, Wensink could score as well. He had a career high 46 points in the 1978–79 season for the Bruins. Wensink also played for the
St. Louis Blues,
Quebec Nordiques, the
Colorado Rockies and the
New Jersey Devils. He finished his career with the
Nijmegen Tigers in the Dutch
Eredivisie in 1984–85. ==Post-playing career==
