I'm guessing that Bowlen is going to try to fire him for "cause" as I just read that the Broncos are still paying Shanahan and if they don't file a grievance (from the video tape stuff) they could potentially be paying three coaches in 2011.
Side note: I don't think they gave him enough time. Sure, he was royally screwing up that franchise...trade away Cutler, Brandon Marshall, Peyton Hillis and that 1st rounder for Alphonso Smith, who was traded to the Lions for peanuts. But I think his gameplanning was good and he's going to be a highly sought after OC. He was just not a good people-person.
