Not a chance that Freeman does not have any input to the game plan
I'm sure for the most part that the coordinators make most of the play calls it is inconceivable that MF is not involved in the game planning. The head coach will make the game decisions like whether to punt or go for it on 4th downs, fakes, and things like clock management but once those decisions are made, it's up to the coordinators to call the actual plays with, for the most part, limited input from the head coach.
