Carr is the key to PC's exodus (My Opinion)

I think he's just not going to fire PA during the season out of respect for him and his tenure here with the organization, but to not remove play calling duties from him is what I do not understand as it does not take the title of OC away from PC but just the responsibility of play calling away, is this a shot against Curry as offensive play caller / coordinator, is Curry on the roster in the same compacity that PC was when Payton was running the offense just as a clipboard holder.
Is DA doesn't make a move on Pete, I think he is digging his own grave. If Pete remains OC the rest of the year, thats basically saying I have no answers and no will to find answers. I get the strategy of not making drastic moves in the middle of a season and creating panic, but this isn't that situation. DA needs to make a serious adjustment in an attempt to turn this season around. Otherwise, its his head on the chopping block too. I don't know if Curry taking over will be enough. If that doesn't work out either, can you say DA really did all he could to fix the season?
