Personally, I don’t like any of the options you mentioned either than Bill or Bowles, and I don’t think either of those happens. Staley’s defense has been an absolute failure with the Chargers, del Rio’s defense has hardly worked ever since he took the Raiders HC job, and Rivera seems out of touch with the way the game has been changing (which is pretty evident when you watch his press conferences). I think our best bet really is to take an assistant from a defense that has been succeeding for multiple years.
It would fit in our recent trend of hiring guys named Matt to be our HC
