From Jay Glazer of FOXSports.com:
The Buffalo Bills have commenced "Operation Cleaning House."
On Monday the Bills fired their entire coaching staff -- including interim head coach Perry Fewell, FOXSports.com has learned. Fewell, however, is expected to officially interview Monday for the Bills' permanent head-coaching position.
The team has already met with former Pittsburgh Steelers head coach Bill Cowher and believes that his interest in the opening is genuine.
Buffalo is also making plans to interview several current assistant coaches to fill their head-coaching void. That list includes Eagles defensive coordinator Sean McDermitt, Cardinals assistant head coach Russ Grimm and Vikings defensive coordinator Leslie Frazier. Other possibilities include Jets offensive coordinator Brian Scottenheimer and Chargers defensive coordinator Ron Rivera.
