I understand that yours is the prevailing view on FR. I personally find that view to be misguided or uninformed, and ROTFL funny when I read it.
There are sound reasons for appointment of an SC, and the situation (basically, the scope of Mueller's jurisdiction) is not at all the way the press suggests or even reports as fact.
Did you know that Trump interviewed Mueller to head the FBI (that's the cover story anyway) a couple days before Mueller was appointed SC?
Who suggested Trump interview Mueller? Rosenstein.
