Skating in a career-high 75 games, he scored 16 goals with 21 assists and was an even plus/minus with 55 penalty minutes. He scored 8 of his 16 goals on the power play.

2012-13: Gelinas made his NHL debut in his second pro season — playing in New Jersey's next-to-last game of the season — and was the top offensive defensemen for the the Devils' AHL affiliate in Albany. He had no points and was -1 in 16 minute of ice time in his only NHL game, a 3-2 win over Pittsburgh. Gelinas scored 6 goals with 16 assists in 57 games for an Albany team that struggled to score goals and was +1 with 46 penalty minutes. The Devils missed the AHL playoffs after finishing fourth in the Northeast Division.
Gelinas is blessed with a tantalizing size/skill combination. There is still a little bit of rawness to his game, much of which can be traced to the fact that he is a converted forward. A strong skating, mobile defenseman, Gelinas loves to lead the rush up the ice and involve himself in the play offensively. He also has a bomb of a slap-shot. His defense and physical play is still a work in progress, but after his first pro season, he showed significant improvement in both of those areas.
Gelinas is expected to compete for a roster spot this season in New Jersey. The club is high on the defenseman that has shown steady progress in his development. He projects to be a second pair blueliner, but his skills can contribute to the power-play.
