I read Cameron's article and, to me, he basically made the case you need to use the entire bullpen and not just a select few arms because, surprise, over used relievers lose their effectiveness. Anyway, I seem to recall a manager that won a couple of World Series rings and one of the relievers later said they had clearly defined roles and basically a rotation within the rotation so on any given day, they knew who was going to be called. Any guesses as to who the manager was?
