I think the Bears intend to hire a great HC. If that HC wants his own GM and that is the hang up for signing, then Poles will be looking for work.
Poles career has not gone as well as he planned. Nate Davis for instance, blindsided him. A few draft picks were wasted on trades and bad players selected. I am not saying Poles has been bad, because he has done decent with the tools he had. This offseason he can be in great position to fill some major voids with the first 4 picks in the draft that could redeem his job.
But if a great HC wants someone else to work with, then we have to end the Poles era.
