They were led by fifth-year head coach Shane Burcar and split their home games between Rolle Activity Center and Findlay Toyota Court. The Lumberjacks competed as members of the Big Sky Conference.
Previous season The Lumberjacks finished the season 12–23, 5–13 in conference play to finish in ninth place. In the Big Sky tournament, the team defeated Idaho, top-seeded Eastern Washington, and Montana to advance to the championship game. The Lumberjacks were the first 9-seed to ever advance to the championship of the Big Sky Tournament. Their run came to an end one victory short of an NCAA Tournament appearance with a loss to Montana State to end their season. Had they clinched the auto-bid, the Lumberjacks would have had the lowest winning-percentage of any team in NCAA Tournament history.
