Rough and tumble Gerald Diduck was chosen in the first round of the 1983 Entry Draft, 16th overall by the New York Islanders. The big, bruising rearguard was considered a solid defensive defenseman who always managed to clear way of opposing forwards for his goaltender in the junior ranks, and the Islanders expected the same of him in the NHL.
As a junior with the Lethbridge Broncos, Diduck scored just 19 goals in three years, but ten came in his final year to go along with 24 assists and 133 minutes in penalties.
As a 19-year-old rookie, Diduck dressed for 65 Islanders games in 1984-85. He had two goals and eight assists with 80 penalty minutes. After spending most of the next two seasons with the Springfield Indians of the AHL, Diduck was called up for full-time duty with the Isles in 1987-88 when he played in 68 games. The following year was his best in the league when he scored eleven and assisted on 21 others while spending 155 minutes in the penalty box.
After a short 32-game stint with the Montreal Canadiens at the start of the 1990-91 campaign, Diduck was shipped off to the Vancouver Canucks, where he patrolled the defense for the next four years. The 1991-92 season was a particularly ornery one, even by Diduck's standards, when he spent 229 minutes cooling his heels in the penalty box.
The closest he ever came to sipping champagne out of the Stanley Cup came while a member of the Canucks in 1993-94. The Cinderella Canucks advanced all the way to the Cup finals before losing a tough seven-game battle with the New York Rangers. Diduck played in all 24 Vancouver post-season games, scoring a goal and seven assists.
During the following season he was dealt to the Chicago Blackhawks where he lasted just 13 games. He has the distinction of actually having played more playoff games than regular season games with the club: 16 to 13.
The next NHL stop was a one-and-a-half year stay with the Hartford whalers. In 135 games he scored just two goals. The Phoenix Coyotes than grabbed him and he played there for a year. By now it was evident Diduck was useful as a fill-in player, but he was no longer able to handle the responsibilities of playing a regular shift. He had a 26-game experiment with the Toronto Maple Leafs in 1999-2000 and finished his NHL career with a 14-game performance with the Dallas Stars in 2000-01 before deciding to hang up the skates.
