Allen is going to be who Allen is going to be, especially towards Carr. Hell, for all we know maybe he knows Derek's psyche a bit better than we do, and not publicly hanging him is/was the best way to go. Still, defensive head coaches never have the best relationships w/ QB's because they live on different sides of the ball. If there was going to be anyone reprimanding Carr/Holding him accountable it would be the OC..ie Pete.
