If there’s anything Brown can work on with Williams, it’s getting the ball out quicker.

That wasn’t an issue earlier, especially in Weeks 3 through 6, when Williams threw nine touchdown passes with five interceptions.

He has nine more touchdown passes, but has been sacked 22 times in his last four games. As a result, Williams was sacked more times than any quarterback (38) and the offense struggled badly.

It is not the only reason, but one of many that led to Waldron’s dismissal.

“It’s hard, just because you’re working all the time, I think, forgetting how many months it’s been, you’ve been working for months,” Williams said. “I knew Shane before he was drafted here because of the process and stuff.

“I’m trying to build that rapport, build that rapport. The guy you tried to get on the same page with is no longer here. So now you have to adjust and you have to adjust quickly because we’re in the division, the division game this week.

Giving Williams was not considered because, as Matt Eberflus is quick to point out, rookie quarterbacks need reps. It’s part of the reason he had Williams on the court late in the last two games behind the scrimmages when the game was already lost.

“I think the last two weeks, I probably held on a little bit longer than I wanted to or expected,” Williams said. “I definitely think I can do a better job with it, just being a little more focused on making sure I’m taking care of the details, just understanding the situational play.

“I think this past game, we didn’t do as good a job as I wanted with situational play and held the ball a few times too much. That stat goes for offensive lineman and stuff like that I wasn’t on the job I got a couple of sacks I shouldn’t take the ball out of my hands be decisive and I have to start now.

If you get rid of him faster now, Williams could stay on the field. Although the rookie needs reps, Eberflus wouldn’t rule out retiring him in the future.

“I would just say we’ll look at everything weekly, we always do,” Eberflus said. “What’s best for the football team — we made a big decision last week (firing Waldron). You always have to evaluate that.

“The things you did well, the things you need to improve on, where your football team is and where you need to go right next week. I think that’s important.”

It would seem unlikely that GM Ryan Poles would allow this.

Williams averages 3.03 seconds to throw according to Pro Football Focus, 2.9 seconds according to NFL NextGen Stats. Both are much slower than earlier in the season when he was in the 2.7 second range, though he’s still in good company. Brock Purdy, Lamar Jackson, Jalen Hurts and Sam Darnold are all slower.

Eberflus’ goal of preventing too many possessions, too many sacks and no scores count on this change of coordinators to help the spring receivers open to change.

“What I look for in the offense is creativity,” Eberflus said. “Working guys into open positions down the field, that takes creativity. It takes everybody to be able to do that.”

NFL NextGen Stats keeps track of average separation for receivers, and the only Bears receiver ranked in the top 50 in it is tight end Cole Kmet, sixth overall in the league (4.3 meters).

However, they have failed to get Kmet the ball in the last three games. He has five catches for 23 yards in those games, four of those in the last game.

So Brown will roll up his sleeves and get to work.

“I think we’re going to do a good job of marrying everything together, making everything look the same,” Williams said. “Then from there, you’re going to get a few easier passes, a few more layups.

“I think he’s going to help us in the run game. I think it will help us in the passing game to be able to do that. I think from there, it gives us a little bit more explosion as an offense and being able to help the complementary football issue that we really want to attack.”

There are jobs on the line, maybe even Williams’ — though as a rookie in need of reps, he seems to be the safest around Halas Hall.
