What are the Chicago Bears talking about ahead of Sunday's NFC North matchup against the Lions at Solider Field? Let's find out:

1. Bears interim head coach Thomas Brown said they have to fix some of the protection issues that plagued them early last week in the loss to Minnesota, and really that have plagued them all season. Chicago is tied with Cleveland for the most sacks allowed this season (58).

Brown also talked about how rookie quarterback Caleb Williams has to get through progressions quicker and get off things faster in certain situations. It's a point of emphasis this week heading into the Lions game Sunday.

2. Williams said Wednesday one of his biggest frustrations this season has been some of the missed throws and opportunities for big plays he hasn't connected on. Those accuracy issues eat at him. He is completing 61.9 percent of his passes. The league average is 65.2. Williams said Wednesday he sees progress in his accuracy, but it's been frustrating missing passes.

3. What did Brown identify as the biggest problem for his team in the first half against the Lions on Thanksgiving in Week 13? Chicago had just 53 yards of offense and trailed Detroit 16-0 at the half in an eventual 23-20 Lions win.

"Don't commit penalties and get open vs. man-to-man," Brown said. "That'll solve the problem. That was the biggest issue."

4. After watching the tape of the first game against the Lions, what does Williams think he and the offense have to do to score more and change the outcome this time around? Williams said it's simply execution.

"That was one of the biggest things," he said. "In the first Detroit game, they started manning us up a little bit. Throwing accurate passes, pass protecting, running the ball well. Winning on man routes. I think that's what started to click in that second half of the last Detroit game and what wasn't in the first half."

Chicago will look to start much faster offensively at home Sunday.

5. Brown was asked about taking advantage of a Detroit defense that's dealt with injuries and has given up 30-plus points in back-to-back contests vs. Buffalo and Green Bay.

"I think what you said about injuries is going to play a big part in it," he said. "When you have guys go down at the rate they've had go down, it does have an effect on how guys play and produce.

"They are an aggressive group. They do play a lot of man coverage and some of those plays have been guys getting beat one-on-one. Also, some of those points have come off certain individuals who have super-human ability to create some off-schedule plays and break tackles to extend plays as well."

Brown said he sees Detroit's defense being the same and playing the same as the defense they faced three weeks ago, despite the injuries, and they'll have a similar plan to attack them.

6. Williams described his rookie season up to this point as both frustrating and encouraging. The frustrating part has been the current eight-game losing streak the Bears are on. He's never experienced anything like this in his football career.

The encouraging part is how much he thinks he's grown and progressed through the frustrating times. He's been consistent in his process, and he thinks that will serve him well moving forward.
