Morris is a good player to have on your bench. He can create his own shot and is capable of carrying the offense for a time. That is useful, especially for a team like the Celts that only has one bona fide offensive star in Kyrie. He is inconsistent. He is not efficient enough. He takes excessively difficult shots. Those things are all true. But if he was consistent, efficient, and took only good looks he would be a star and wouldn't be available as a bench player on a favorable contract. Oh by the way, he can defend pretty well too. He is a high quality bench player and he makes the Celts better.
