If given the opportunity, most people will step up and show themselves "great." Of course that doesn't mean that everyone on your project team will respond to an increased level of autonomy. If you have someone who doesn't or won't step up, you must decide if they are trainable, or if they might be better suited to another team someplace else. However, I have met very few people who qualify as unteachable.
Creating an environment that empowers the team is not only easy, but in the long run it empowers you. As author and teacher Barbara Coloroso said, "The beauty of empowering others is that your own power is not diminished in the process."
