The Daily Scrum is an event for and by the Developers. They can choose whatever structure and technique they want, as long as they focus on the progress toward the Sprint Goal and produce an actionable plan for the next day of work12. The Scrum Master, the Product Owner, and the person coming in last are not necessarily the ones who should start the Daily Scrum. The person who has the token is a possible technique, but not the only one3.
