Nagy spent one season with Patrick Mahomes in 2017, then Alex Smith’s backup, before trying to turn Mitchell Trubisky’s career around in Chicago. Trubisky, the No. 2 overall pick in the same draft as Mahomes, was a pro bowler in 2018 but struggled in subsequent years, leading to Nagy’s firing in 2021.
After returning to Kansas City in 2022, Nagy served as quarterback and then OC for Mahomes during their three-year Super Bowl run. Mahomes won MVP honors with Nagy as his QBs coach in ’22, as the Chiefs ranked No. 1 in total scoring offense. Nagy served as OC for Kansas City’s win in Super Bowl LVIII and made a run to Super Bowl LIX, where the Chiefs were swept by the Eagles.
Kansas City’s offense took a significant downturn in 2025, ranking 21st and 20th in scoring and total offense. It continued the statistical decline with Nagy as OC from the 2022 peak. The Chiefs brought back former OC Eric Bieniemy this offseason to replace Nagy, who will now try to ignite the career of another young QB in New York.
Offensive Rookie of the Year finalist Jaxson Dart will be the biggest beneficiary of Nagy’s hiring in New York. The fiery signal-caller had an up-and-down first year in the NFL amid injuries and coaching turmoil. The Giants fired coach Brian Daboll, who helped draft Dart in the first round, midseason and elevated OC Mike Kafka to the interim role.
In 14 games, Dart completed 63.7% of his passes for 2,272 yards, 15 touchdowns and five interceptions. The dual-threat forward added 487 yards and nine scores on the ground. The Giants QB also struggled with a concussion, a possible byproduct of his aggressive play out of the pocket.
Nagy will be tasked, as he was with Trubisky and Mahomes, with building an offense around Dart’s arm and mobility while also containing free spirit for years to come.
If Nagy is able to perhaps see Dart reach his potential in the first round, then a ridiculous second chance at a head coaching gig awaits him in the future.
