2006-07: The Gatineau Olympiques selected the towering Steven Delisle with their second round selection in the 2006 QMJHL Draft, out of his hometown Lévis system. In his first season in the league, he served as the sixth and seventh defenseman on an underrated defensive group, playing a safe, shutdown role in his 53 games.
2007-08: With four rookie defensemen in the line-up over the course of the season, and the departure of a few key components from the back end of the Gatineau line-up from the previous season, Delisle was used more regularly, playing top-four minutes for the Olympiques. The big blue-liner also ended up seeing plenty of power play time for Gatineau during the regular season. While a couple of mid-season trades brought in some defensive help in Joey Ryan and Patrik Prokop, Delisle still finished with 29 points (six of which were goals), good enough for second on the team. He also added 10 assists in 19 playoff games, using his size and sound decision-making to shut down the offense, and helping his team to the league championship and an eventual Memorial Cup berth. Delisle was drafted by the Columbus Blue Jackets in the fourth round, 107th overall, of the 2008 NHL Draft.
2008-09: Delisle played in 63 games during his third season with Gatineau, scoring 5 goals and 25 assists for 30 points. He led the team with a career-high 94 PIMs but also had the worst plus/minus rating at minus-14. In 10 playoff games, the blueliner added 2 goals, 3 assists.
2009-10: Opening the season with Gatineau, Delisle scored 4 goals and 19 assists in 39 games. He was moved at the trade deadline to Rouyn-Noranda in exchange for winger Ben Miller and draft picks. In 25 regular season games with the Huskies, Delisle notched 1 goal, 5 assists. He added 1 goal and 3 assists in 11 playoff games.
2010-11: Delisle skated in just six games with the Central Hockey League's Fort Wayne Komets in his first pro season – suffering a shoulder injury that required surgery in late November. He had no points and was -2 with 2 PMs in his brief tenure with the Komets.
2011-12: In his second season in the Blue Jackets organization, Delisle appeared in six AHL games with Springfield; spending most of the season playing for the ECHL's Chicago Express. He was plus-two with 8 penalty minutes in limited ice time for Springfield. Delisle had 1 goal with 3 assists and was minus-five with 20 penalty minutes in 38 games for the Express. He was traded to the Rangers in July 2012 as part of the Rick Nash trade.
Delisle was dealt by the Columbus Blue Jackets to the New York Rangers in the deal that brought Rick Nash to the Rangers in 2012, then was dealt back to the Blue Jackets at the 2013 NHL trade deadline in the deal that sent Marian Gaborik to the Blue Jackets.
