LAKE FOREST, Ill. (AP) — The Chicago Bears remain committed to Mitchell Trubisky as their starting quarterback despite his struggles this season, general manager Ryan Pace said on Tuesday.

Pace stopped short of saying the Bears will exercise their fifth-year option on him and did not rule out bringing in an experienced veteran who could push for the starting job. But he made it clear the Bears expect Trubisky to open next season as their No. 1 quarterback.

“Mitch is our starter,” Pace said. “We believe in Mitch and we believe in the progress that he’s gonna continue to make.î”

Though the Bears are sticking with Trubisky, they are shaking up their coaching staff.

Offensive coordinator Mark Helfrich and three other assistants were fired. Offensive line coach Harry Hiestand, tight ends coach Kevin Gilbride and assistant special teams coach Brock Olivo were also let go.

Helfrich led Oregon to a 37-16 record and a run to the first College Football Playoff championship game as the Ducks’ head coach from 2013 to 16. The Bears hired him as their offensive coordinator in 2018.

With coach Matt Nagy calling the plays, Chicago showed some flair before taking a step back this season. The Bears ranked 29th on offense, 27th in rushing, 25th in passing, 27th in touchdowns and 29th in scoring.
