Harbs, Trestman, and the Offensive coaches are all safe. No reason to fire any of them and throw the team into flux ANOTHER year on offense. At least next year, they can have the consistency of having a coordinator for more than one year. I could see them hiring a QB coach though to correct Flacco's regression though. As far as the Defensive coaches are concerned, you might see some of them gone by the Bye week. Hewitt is destined to be fired at this rate, and Pees just can never seem to field a good defense. He's been solid in past years, but never good or great. Brooks for sure stays. The team just keeps taking his good players, and he keeps finding ways to preserve the D-line
