had a total of three head coaches in the last 55 years (and counting). They’ve ridden out the ups and downs and generally done better than average. They’re among the leaders in Super Bowl victories.

Also look at the Dallas Cowboys after Jimmy Johnson. Holy coaching carousel, Batman! And what good does it do them?
