Outlaws led for most of the game by as many as four goals when the score reached 10–6 with three minutes left in the third. However, after taking a 12–10 lead with 10:30 to go in the game, they gave up seven straight goals and lose their fifth championship game in their seventh appearance, 17–12, allowing the Machine to win their franchise's first title. Much like their 2016 championship season, the 2018 Outlaws struggled out of the gate. On Mother's Day, the Outlaws dropped a 24-22 barnburner to the Chesapeake Bayhawks in front of 1,788 fans at Mile High. But the resilient Outlaws rattled off six straight victories ending with a 25-11 blowout of Boston at their annual Fourth of July game in front of 29,973 fans. The team finished 8-6 and in third place. Despite getting swept by the Bayhawks 2–0 in the regular season, the Outlaws would go to Annapolis and get a gutsy 13–12 victory in the league semifinals. The following week in Charleston, South Carolina, the Outlaws would face the Dallas Rattlers, who also swept them in the regular season, for the 2018 Steinfeld Cup. Denver would use a 7–0 run in the second and third quarters, and a nine-point performance from Matt Kavanagh to defeat Dallas, 16-12 for their third championship in five years. Rookie Chris Cloutier won Rookie of the Year for the 2018 season. After the departure of over 140 MLL players to the new Premier Lacrosse League attributed to the contraction of the league from nine to six teams, the Outlaws posted a 9–7 record in 2019. Despite tying their franchise record for most losses in a season, with the longer regular season the Outlaws claimed the second seed heading to the championship weekend, which would be played in Denver for the first time. Although the Outlaws rallied to defeat the Boston Cannons, 17–15 in the semifinal, they were not able to ride the homefield advantage to their fourth title. The Chesapeake Bayhawks left Denver as victors, 10–9, after scoring two goals in the last three minutes. The 2020 season was shortened due to the COVID-19 pandemic and quarantined at Navy-Marine Corps Memorial Stadium in Annapolis, home to the Chesapeake Bayhawks. In a five-game regular season, the Outlaws stormed to a 4–0 start highlighted by an 18-6 throttling of the new Connecticut Hammerheads and a 13–12 overtime victory over the defending champion
