Bears QB Caleb Williams expressed frustration on the team's slow offensive start against the Chiefs on Friday night.

Williams is the third Bears first-round pick since Mitch Trubisky was drafted in 2017 to have to learn a new playbook — and play for a new head coach — in his second season.

Chicago Bears head coach Ben Johnson is not seeing the development he wanted by the end of the preseason. The first-year head coach was frustrated by Caleb Williams and the first-team offense having the same issues pop up that they had at the beginning of training camp.
