The following year, Brennan was a staple defenseman on the league leading Marlies, remaining at a point a game throughout the season and recording the second most points in the AHL.

[24] On April 4, Brennan scored his first goal in the NHL in nearly 3 years, potting one in a 4–3 defeat of the Florida Panthers. Coincidentally, Brennan's last goal was on April 11, 2013, while playing for the Panthers.
