Caldwell out in Detroit, Fox out in Chicago. Fox is a bit puzzling to me. He came to the organization just three years ago, and they obtained the guy that they view as their franchise QB an offseason ago. Letting him go, despite 3 poor years, seems indicative of the increasingly short leash on coaches throughout the league. EDIT: Corrected that Fox had three poor years. Nonetheless, they improved this year, in the first that they had their QB.
