MIAMI — More than four months into a remarkable turnaround, the Celtics seem determined to keep it going. Behind Jayson Tatum and Jaylen Brown, the team’s two young stars, Boston is bound for the N.B.A. finals after defeating the Miami Heat, 100-96, in a decisive Game 7 on Sunday in the Eastern Conference finals.
Boston won the series, 4-3, and will face Golden State in the N.B.A. finals, starting Thursday in San Francisco. Tatum was named the most valuable player of the Eastern Conference finals, a new honor this season. The trophy is named for the Celtics icon Larry Bird.
