Of course, but in this case it's a discussion that seems to be lost from the start and in the end, it's manager who's getting judged on his performances that are produced by players who DOF picked for him and such might not fit his vision.
How do you even know that?
And the 2nd bit is again coming to the original point being made. Yes, its the manager that will be judged but different clubs do it differently based on the factors like how long they expect the manager to be there and thus whether his decisions are good for the long term future of the club.
