WASHINGTON, D.C. — The Washington Wizards have resorted to “Finding Nemo” references to keep themselves sane amid a 3-19 start, but Saturday’s 131-116 loss to the Atlanta Hawks was a step forward after a 45-point loss to the Jayson Tatum and Jaylen Brown-less Boston Celtics on Thursday. Nothing was more encouraging for the organization’s future than rookie wing Will Riley’s career-best performance.
