John Fox has been able to fix teams quickly in both his previous stops, but the going has been much tougher in Chicago. And if he continues next year as head coach, some changes to his staff could be inevitable.

Via Mike Mulligan of the Chicago Tribune, one of those on the way out could be veteran defensive coordinator Vic Fangio, as part of a “massive overhaul” of the team’s staff after a disappointing 3-9 start obscured any of the strides they made going 6-10 last year. According to the report, that overhaul won’t include Fox himself.

The Bears have plenty of problems, beginning with injuries and suspensions this year. But many would identify the problems with their offense, as they’ve struggled since replacing offensive coordinator Adam Gase with Dowell Loggains.

Fox hiring Fangio in Chicago was a bit of a surprise to some, as Fox has always run 4-3 defenses and Fangio was a 3-4 guy. But the Bears are built to play a three-man front now, and changing that might create another layer of problems.

If they make a change at all, as coaches get notoriously jumpy this time of year as they look for future employment.
