FWIW, here's the statment the Broncos put out:
I find it difficult to believe that the Bears weren't one of the many teams that called to see what the Broncos were thinking. This is going to be a long, long process if he does wind up moving. There's certainly no guarantee the Bears can put together the best offer (The Lions you know, do need a QB, and if I were them I'd move their pick for him). Denver is going to be the stubborn one here.
