All those coaches have a very big thing in common(excluding Fewell because he was an interim coach): they were/are all bottom-five in the NFL in SALARY. This organization, Ralph Wilson in particular, has never placed a premium on coaching or management. Only one time has Wilson gone out and got a top-notch coach in Chuck Knox in 1978, who promptly turned around a terrible Bills team and took them to the playoffs in '80 and '81, only to get into a contract squabble with Ralph Wilson (can anybody sense a theme here!!!) and leave for the Seahawks, promptly turning around that team. He got lucky hiring Bill Polian, who was a nobody at the time. He got lucky with Marv Levy, who was every bit a re-tread when he was hired, and one can certainly argue that a coaching change was warranted after the Redskins Super Bowl loss or the first Dallas loss.The problem here is that in 80's and 90's, you could win some games and have good seasons with having a very talented roster because teams that were less talented than you were took much longer to turn around into winners. That is not the case today. The NFL is ALL about coaching. And if it's not all about coaching it is certainly 80-20 coaching to talent. Yes, QBs are very important, but you don't win Super Bowls with bottom of the barrel coaching hires.
