Still unclear is what will change. Could it mean Nagy will relinquish his play-calling duties? He declined to say if he will hand over that responsibility.
"I'm not going to get into all of that," Nagy said. "If I did, no one (in the public) would know."
Bears offensive coordinator Mark Helfrich would be the logical candidate to take over those duties. As head coach of Oregon, he was heralded for offensive innovation as part of the Ducks' success.
Before becoming coach of the Bears in 2018, Nagy assumed play-calling duties as the Chiefs offensive coordinator late in the 2017 season when coach Andy Reid relinquished them.
On Sunday, the Bears had just 252 yards of offense and averaged 4.0 yards per play, with the majority of their production coming with the game out of reach in the fourth quarter. Nagy's offense posted only 85 yards of offense and 2.4 yards per play during the first three quarters.
Quarterback Mitchell Trubisky was 34-of-54 for 251 yards and two touchdowns, struggling for three quarters before piling up numbers in the final 15 minutes.
Nagy's greatest concern was the Bears' lack of a rushing attack. They managed only 17 yards on seven carries.
"The run game has to get going," Nagy said. "As simple as that -- it just has to get going. You can’t run for 17 yards in the NFL and think you’re going to win a game. You should get 17 yards on one run play.
"Something’s got to change, and something will change."
