Yes. But to be more precise: this doesn't evolve out of nowhere. For example at Dortmund since this season Kehl is a "second" DoF, being between the squad/the dressing room and Zorc (DoF). Its an open secret that he will climb the ladder and take Zorcs position when Zorc climbes the ladder and will be CEO (when Watzke retires). So there is plan behind, teaching and learning for all the important people who have something to say in the Club. And Dortmunds buying new players was and will always be the result of different people: Head of recruitment, the DoF, now Kehl in addition, and the CEO (Watzke) working together, Sammer as an counseler "outside the club" is another person who have something to say in all these things.
Or another example, the mentioned Mislintat above: He was a scout, then head of recruitment at Dortmund, now climbes the ladder and is hired as the DoF at Stuttgart. Which i think is a great move from them, and all the footballworld here in Germany says this is a coup from Stuttgart, very clever.
