I too was pissed at some mistakes I have seen from the coaching end of this team. But sometimes we need to shut our traps and let these things play out. I have a feeling we are in good hands. And have some continuity going forward.
I think Sherman was brought in just for Tannehill. To make his transition to the NFL easier. Now that Ryan is comfortable, he needs a coach to push his limits. I am not so certain that Sherman is the right guy.
