LOL The middle of the Bears offensive line has been trash ever since Poles arrived. The center position has been a revolving door of incompetence. Jenkins spends as much time on the injury report as on the field. Poles gave Davis a $30 million contract. He’s been so bad they just cut him. If Poles doesn’t get fired, he will pour free agency and draft picks into the OL.
I've seen that they've had some issues with injuries and having to move guys around (I didn't know how bad it was the past few weeks until I saw your post and I looked, though, so points on that. I don't doubt this is a big reason why the Bears have gone 23 drives without a touchdown right now).
However, the fact remains that
overall this season the Bears offensive line is putting up above average numbers in: Pocket time, time to pressure, run stuff rate, run block win rate, and pass block win rate. (Grubb would probably have to go see a doctor because it had been lasting for more than 4 hours if he had an offensive line that was able to do that. Right now, the Seahawks are--I believe--bottom 5 in all but 1 of these things... where we are still bottom 10.)
When I watch the video of Caleb Williams' sacks (and there is a LOT of video of that), what stands out is how many of the sacks come from unblocked extra rushers. Is this a line issue? Yeah, kind of and it's probably not helped out by how much rotation of pieces they've had to do. But it's also just as much a scheme and (yes) QB issue.
This is the opposite of what the Seahawks issues have been, as we actually don't allow dudes to get completely unblocked to the QB. The reason why we still have the worst time-to-pressure rate in the NFL is that our guys are just getting so badly beat, so consistently (particularly on the right side).
Bears have an overall
protection problem, and the need to play musical chairs because of injuries is certainly not helping with that, but it's not nearly as specific to the offensive line as what the Seahawks are dealing with.
