I don’t care who Carr had success with in the past, I would hire the best available OC for the team. Carr can get on board with the new OC, and the team can flourish, or he can continue being meh, and we can show his arse the door after next season. The choice is his.
Well with Musgrave DC and the Raiders went 12-4 with a bad defense that good enough for you? Smith and Callahan are working under 2 successful HCs in Zach Taylor and Mike McDaniels.
