The Arizona Rattlers left the AFL for the IFL following the 2016 season, keeping coach Kevin Guy, who had led them to several Arena Bowls. In their new league, they lost three of their first five and got out to an unimpressive 4-4 start, losing three games at home. Cody Sokol, however, took the team to amazing heights, winning eight in a row and turning mediocrity into a title season. He passed for 1,462 yards, 35 touchdowns and seven picks in twelve total regular season games. Darrell Monroe led the newly found Rattlers' run game, with 721 yards and eighteen scores. Anthony Amos led all receivers with 19 scores and 602 yards. Arkeith Brown picked five passes and Allen Chapman intercepted eight, as well, for what became a strong defense. The defense racked up 27 regular season sacks, with an additional three in the United Bowl at Sioux Falls. After falling at Sioux Falls in week one of the season, Arizona built a 34-7 halftime lead and stunned fans. Despite a furious comeback that saw the lead cut to 34-28, Arizona hung on for a 50-41 victory, dethroning the Storm for the first time in seven years. Arizona remained in the league for 2018, after some offseason controversies in which the Rattlers' ownership was accused of bribing West Michigan and Bloomington's franchises into joining the IFL and leaving the CIF. The CIF sued and both teams were precluded from playing at all in 2018. On the field, Jeff Ziemba took the Rattlers through an 11-3 regular season. He completed 61% of his passes for 1,745 yards, 39 touchdowns and eight interceptions. However, at season's end, Ziemba suffered a season-ending injury and Vernon Reed took the reigns going into the postseason. Darrell Monroe again led the ground game, rushing for 782 yards and 28 scores. He, too, though, would fall in the first quarter of the playoff game the Rattlers hosted against Sioux Falls. After losing three regular season games to Iowa, but beating Sioux Falls twice, Arizona hosted the Storm and had a chance to win the game on a 24 yard field goal with time running out. The kick went wide and the game went to overtime where Arizona scored first, but the extra point was blocked. Sioux Falls would score on their first play of overtime and won on the extra point kick, 69-68.
