I like a lot of the things he's done, and I definitely think he's better than Pace. But I think his weaknesses are coming through more distinctly lately, and they may end up costing him his job.
Every Bears fan and prognosticator on the planet could see the issue coming of drafting a new first round quarterback while keeping a coach who probably wasn't going to work out. Poles chose the low-percentage play.
Every Bears fan and prognosticator could tell you what happens when you put a young quarterback behind a really shitty o-line. (paging Jay Cutler, Mitch Trubisky and Justin Fields). Poles chose the low-percentage play.
The Bears organization are now in a very tough position, personnel-wise, and Poles has himself to blame. For the sake of argument, let's say Warren lets Poles hire a new head coach. Now Poles is in a position where he's first on the chopping block if there aren't immediate and significant improvements. Then they fire Poles, keep the head coach for a year or whatever, and we repeat this whole process again.
By the way, the wildcard in all of this remains Kevin Warren. We really don't know what he thinks or how much power he truly has. We know the dude has a sizeable ego. Is it enough to show Poles the door after this season if things continue to spiral? Warren may be eager to show his own chops & value, and knows the longer Poles sticks around, the more Poles gets the credit and not himself. If he hires his own GM, though, Warren gets the glory if he can turn things around. Something to keep an eye on.
