And even if it is, complexities exist. The relationship between Fox and Fangio, the reputed brains of the outfit, makes it difficult to envision both working together for a fourth season. A coaching coup resulting in Fangio deposing Fox for 2018 sounds like something more likely to be seen in a "Ballers" script on HBO than Bears reality. As valuable as Fangio is, you wonder if he has done such a good job instilling a mindset that the players would perform well even if he leaves and Fox stays. Not often do assistant coaches win NFL power struggles.
