You're giving a lot of other coaches WAY too much credit.
Just off the top of my head, Staley, Rivera, Lafleur, Saleh, McDaniels (fired), Pierce, Dennis Allen, Arthur Smith, McCarthy....arguably Daboll, Reich, O'Connell.... all could easily be worse with this same team. That's way above bottom 5. If you don't think so, I don't think you're being honest and you're just emotional after a loss.
