followed with a six-game losing streak. With the offense's struggles persisting through the first nine games of the year and through the stretch, including being ranked 29th in points per game and 31st in yards per play, Nagy relinquished play calling duties to new offensive coordinator Bill Lazor. Despite losing a Week 17 contest to the Packers where a win would have guaranteed them a playoff spot, the 8–8 Bears made the postseason for the second time in three years under Nagy due to winning a tiebreaker with the Arizona Cardinals. They were subsequently eliminated in the Wild Card round with a 21–9 loss to the New Orleans Saints. Following Trubisky's departure via free agency, the 2021 season began with Andy Dalton as the Bears' starting quarterback over first-round rookie Justin Fields, while Nagy promoted safeties coach Sean Desai to defensive coordinator after Pagano retired.

Chicago would finish the season with a 6–11 record, their first losing season since 2017 and Nagy's first as a head coach. On January 10, 2022, both Nagy and general manager Ryan Pace were fired by the Bears. Nagy's tenure in Chicago concluded with a record in four seasons, including an 0–2 playoff record. In a statement released following his dismissal, Nagy thanked the team "for the opportunity to lead one of the game's most storied franchises" and described his stint as "four years I'll always remember."
