Allegedly, Ben Johnson is who Warren wants. And is willing to break the bank for him. Supposedly, its not going to be about money, but whether Ben feels like Poles can convince him that Poles has learned from his mistakes, and if not, whether Warren can convince the McCaskeys that they will have Ben if they let go of Poles.
I would also not be surprised if Ben gets some say (maybe even final say) in the personnel decisions if he comes here. Just my speculation, but while the expectation is Poles will be extended to match whichever coach comes in, do not be surprised, especially if Johnson is given some personnel power over player procurement, if Poles is NOT extended. There are a pair of assistant GMs waiting in the wings, both in Detroit (Agnew) and I think it was the Rams? either way, there's been a couple of names attached to Ben Johnson.
If they can't push Poles out now, I'd speculate they would ride the pine with him until his contract is up and then go after one of the guys Ben really wants - so Bears, but the McCaskeys are likely always gonna McCaskey.
