The Tri-Cities Fever entered its third league in the IFL after the dissolution of the af2. The team's wins came against Fairbanks, Alaska, and Kent, all three losing teams. Houston Lillard and Andy Collins quarterbacked the team, combining to throw for 51 touchdowns and 13 picks. Thyron Lewis caught 25 of the scores. He also led the ground game with seven rushing scores. The Fever scored 52 points per game but gave up 50. After a regular season loss at BIllings to end the year at MetroPark, the teams were set to play again in the playoffs the following week. The day after the game, though, MetroPark was destroyed by a tornado. The game was moved to the Billings SportsPlex, an Outlaws practice facility. Tri-Cities took a 35-32 third quarter lead, but Billings pulled out the 54-45 victory in front of 800 fans at the new venue. The Fever were hungry to repeat the success of 2010 in their second IFL year and they did. Houston Lillard quarterbacked the team to a 10-4 regular season record, throwing for 2,517 yards, 68 touchdowns, and 15 picks. He also ran for eight scores. Key Hew Len racked up 848 yards and 25 scores to lead all wide receivers in the IFL's second best offense. Oliver Young added 20 receiving scores and 728 yards. Dennis Rogan led the defense with nine picks. Tri-Cities did not have many impressive regular season games, minus a home victory over Colorado. However, the team really hit its stride in the postseason. Trailing 36-34 to start the fourth quarter at home against West Texas, but scored 34 points to win going away, 61-49. The Fever used another strong second half, outscoring the Colorado Ice 24-7 in Loveland to secure a 45-42 victory. Fever fans harkened back to the 2005 season in which the Fever defeated undefeated teams in the playoffs back-to-back on the road. Tri-Cities was again on the road, this time against the Allen Wranglers. Again, a strong fourth quarter saw the Fever outscore Allen 17-7 and advance to United Bowl VII with a 57-46 victory. This was despite two late turnovers that could have allowed the Wranglers back in the game. United Bowl VII was in Sioux Falls against the always powerful Storm. Lillard and the offense were held to ten points through the first half, but were able to hold the Storm offense to just 17. However, the second half success would come to a screeching halt, as the Storm won the second half 20-0 to take a 37-10 championship victory. Houston Lillard again led the team in 2012, throwing for 2,720 yards, 59 scores and ten interceptions. Steven Whitehead caught 84 balls for 791 yards and 20 scores. Oliver Young amassed 735 yards and scored 14 times. Lionell Singleton led the defense with 98 tackles and 11 interceptions. The team competed in several close decisions, especially toward the end of the year. After a crushing 55-16 loss at Sioux Falls, the Fever went on to beat Wyoming 30-26 before facing Sioux Falls again. In a game where Sioux Falls was penalized 29 times for 170 yards, Tri-Cities was able to force overtime, but fell 73-72. Six extra points doomed the Fever. The next week, Tri-Cities needed overtime to defeat Colorado 52-49. Tri-Cities was the top seed in the Intense Conference and hosted Colorado in the first round of the playoffs, defeating the Ice 52-42 and then Wichita 51-30. The team returned to Sioux Falls for the second year in a row for a title bout. Sioux Falls took a 20-10 lead early, but was outscored 37-12 in the second half, falling again to the Storm 59-32. Dante Warren quarterbacked the Fever in 2013, throwing for 1,472 yards, 28 touchdowns and just three interceptions. He was also the team's leading rusher, scampering for 593 yards and thirteen scores. His top receivers were Steven Whitehead and George Bell, who both caught nine touchdowns. Whitehead caught 44 balls for 451 yards. Keithon Flemming ran for 407 yards and fifteen touchdowns. The team went 6-8, finishing third in their conference and missing the playoffs. Five of the team's losses came on the road by 4, 3, 2, 4 and 5 points respectively. Opponents were picked off 25 times against the Fever defense, but it wasn't enough to secure close wins or make the playoffs. Dante Warren returned for the 2014 season, but played more of a backup role, throwing for 619 yards, 13 touchdowns and four picks. Houston Lillard spent more time at the helm, passing for 1,874 yards, 37 touchdowns and seven interceptions. Jackie Chambers, Harry Peoples, and Steven Whitehead were nearly equal in receptions, yards, and scores. Keith Flemming ran for 18 scores. The team had a 5 game losing streak early in the year, which ultimately ended their playoff hopes fairly early. All five losses came to the four teams that would end up making the IFL playoffs. The Fever only won two games over playoff opponents; both werre against Colorado. The Fever returned in 2015, led at first by Houston Lillard. However, with his departure four games into the year, the team moved to Michael Box and then finished the season with Dominick Blackmon at the helm. The three combined for 34 touchdown passes and 17 picks. Steve Whitehead caught 17 touchdown passes on 81 catches for 1,032 yards. Andrew Pierce scored 21 times on the ground. In an 8-6 season, Tri-Cities went 1-3 against the other three teams that made the playoffs. While a 32 point fourth quarter led the Fever to a 67-59 victory over Nebraska early in the year, Nebraska won the playoff rematch 86-43. The Fever went 3-13 in 2016, edging out Billings and Colorado twice. Fever quarterbacks only combined for 43 touchdowns and nearly half as many picks at 21. Akeem Foster and Dejuan Miller combined for 25 touchdown catches. At just 36 points per game, the Fever scored more than 40 points just five times all season. The long-standing franchise folded following the 2016 campaign.
