It appears the Kellen Moore thing may be shaky

Well the rumors there are that there are disagreements over control, which were mostly dismissed as McCarthy saving face because he knew Moore was getting the job. Which apparently he isn’t?
Let’s reason out what control elements Mike McCarty would be lacking in a less than ideal world.

We know Jerry Jones is a control freak. So Mickey is already a step up in that he’ll be able to choose his own staff. What’s next, players? Would Mickey actually veto Mikes decisions on personnel? I even feel confident enough to say that Mickey would pivot to the professionals regarding who is on the team, via draft and free agency. Perhaps Mickey would let Mike know if we can make the numbers work on such and such player. I’d also think that Mike Mc doesn’t want to be an accountant.
So, I’m failing to find a responsibility that Mike wants but couldn’t have under Mickey. Anyone want to narrow this narrative down further?
