The NBA draft is less than a week away, and teams and prospects are finishing up a busy period of workouts, research and evaluation.

The rumor mill continues to buzz as usual, particularly near the top of the draft, where there are multiple scenarios in play.

The Celtics are already making moves by trading the No. 1 pick to the Philadelphia 76ers, who initially held the No. 3 pick. The 76ers are expected to take Washington guard Markelle Fultz.
