Bowles took over a very good defense from a very good coach, Ray Horton. A year after trying to salvage the mess left when Reid fired Juan Castillo and line coach Jim Washburn in season, Bowles is the architect of a top-10 defense No. 1 against the run. “I like where we are in our stage,” Davis said last week. Davis was the linebackers coach on Whisenhunt’s staff when the Cardinals went to the Super Bowl five years ago. Davis, meanwhile, inherited a mess and was tasked with teaching an entirely different style of defense. Good coaches get fired all the time in the NFL. The Eagles have won three games in a row, the Cardinals have won four, and their defensive coaches have a lot to do with it.
