In 2016, the Spokane Shock left the AFL and joined the IFL. Charles Dowdell quarterbacked the team into its new foray, passing for 2,735 yards, 63 touchdowns and 21 interceptions. Jefferson Hayes and Carl Sims combined for 34 receiving scores and 1,507 yards. Trevor Kennedy ran for 720 yards and 28 scores of his own. After a 55-44 playoff victory over Nebraska, the Shock squared off for a third time with reigning IFL juggernauts Sioux Falls and fell for a third time, 55-34. The 2017 season looked to shape up much like the inaugural one in the IFL, as the Shock started out 7-2. However, Dowdell would not play again after the team dropped three in a row and six of their final seven to finish at 8-8 and miss the playoffs. Dowdell passed for 1,750 yards, 40 touchdowns and 16 picks in his twelve games, leaving the last four to Aaron Wilmer. Wilmer passed for 386 yards, eight scores and three picks. Bryan Pray caught 61 balls for 646 yards and 17 scores. By virtue of losing to Nebraska by 6 midway through the season, Spokane would've missed the playoffs even at 9-7. The team was rebooted for the 2021 season and returned with a 6-6 regular season and first round playoff loss at Frisco.
