The 2015–16 season was disappointing for Cogliano, who had recorded double digits in goals every year except for that season. Despite his slide in goals, he played on a line along with Ryan Kesler and Jakob Silfverberg, whose "shutdown" play helped the team reach the playoffs for the fourth consecutive year. Cogliano ended the season leading the Ducks in shorthanded goals and points and finishing second among Ducks forwards in hits. He was again nominated for the Bill Masterton Trophy at the end of the season, with the award eventually going to Jaromír Jágr of the Florida Panthers.
