The LumberJax finished on top of their division, becoming the first and only expansion team to win their division in the 20-year history of the NLL. The LumberJax season ended with a loss in the opening round of the playoffs to the Arizona Sting. The LumberJax were less successful in their sophomore season, finishing dead last in the West Division with a 4-12 record.
