I'd like to know, was Rosenstein having regular check-ins with Mueller, and at what point did Rosenstein realize that Mueller was suffering from diminished capacity like Joe Biden is?
If Rosenstein saw Mueller's diminished capacity, why didn't he say something and change the leadership of the investigation instead of keeping an obviously incapacitated person in charge of a very serious investigation?

Mueller was the figurehead. He of the impeccable reputation but Weismann ran the show.
