The offensive coach thing
it was a lot more than that. Bidwill didn’t like the boozy/loud culture in the building which he wasn’t incorrect about and when BA’s health issues kept popping up then Keim was kept on. Also many felt that BA had run his course, too stubborn and old to listen to anyone.
He was allowed to leave/managed out more than ran out.
All fair points, coupled with BA couldn't get out of town fast enough once he knew Palmer was calling it a career.
