I think Warren is trying to essentially take over the Bears, more or less.
My take is this:
Warren kind of has a reputation as a "politician" who is concerned about his legacy. He's always looking for the next thing to help elevate his career.
However it came about, he somehow got his way into Halas Hall, and has been working over the McCaskeys (who are known to be complete rubes and totally gullible), biding his time. I think he was likely getting a lay of the land, and I think part of the dysfunction in Halas Hall is because Trace Armstrong has an oversized presence there (to the point where he was low key angling to be the next team president, and was mad he didn't get it, but then pretended he wasn't interested).
Add to that, the McCaskeys can't afford to keep the Bears once Ginny dies and the inheritance tax kicks in.
I think Warren wants to be the guy to not just build the Bears a stadium, but also bring them a winner, win with his people, and facilitate the sale of the team. And if he can do all that successfully, don't be surprised if he tries to parlay that next into becoming Roger Goddell's replacement as commissioner of the NFL, which apparently is his long term ambition.
All of this is based on rumors and hearsay - 100% granted.
But if it is true, he's going to be cut-throat and ruthless in getting what he wants, and if he can find a back door way to rid himself of Poles, another Trace Armstrong guy, I think he will.
That's why I think for all the people who think Warren is an idiot; I don't think so - not yet at least. He has too much riding on this to fail. And as fans, we may benefit from it.
You might think the scenario I laid out is a bunch of crap - but you better hope it isn't. It's literally the one scenario that has a silver lining as a Bears fan....
