Most, with whom I've worked, were superb at connecting the dots but didn't really bring any dots of their own. They often didn't know specifically what was needed so their guidance could be rather ambiguous but they certainly recognized a good thing when it was produced and used it to its full potential. However, I do recall one actually saying to an employee in a threatening tone: "If you can't tell me what I need, I'll get someone else."
