Despite a Week 1 win in 2017, the Cannons season turned around. At 3–6, the Cannons traded away captain Will Manny and Joe LoCascio to the New York Lizards for Dave Lawson and Chris LaPierre on June 27. On July 14, the Cannons announced that neither Lawson nor LaPierre would suit up for the team that season. Dave Lawson informed team officials that he would be retiring from the league while Chris LaPierre decided not to report to the team. The Cannons finished the season on a six-game losing streak. At 3-11, the Cannons posted the worst record in the league and tied their franchise-worst record from 2001, their inaugural season.
