Isaiah Thomas lay on the floor of the TD Garden, pointing to his chest as the Boston crowd showered him with “MVP” chants. He had just picked up his 50th point of the night—he’d go on to score three more—in an overtime win that gave the Celtics a 2–0 lead over the Washington Wizards in the Eastern Conference semifinals. With a 53–29 record, Boston had captured the top seed in the East and appeared to have one of the most promising futures in the NBA, and Thomas, standing just 5'9", was the team’s catalyst. His sister, Chyna, would have turned 23 that day.
