Will the Celtics first round win over the Magic have prepared them for the likes of the Cavaliers and the Thunder (if they emerge from the West)?

BOSTON — Before the Orlando Magic left Florida to begin their first-round playoff matchup against the Boston Celtics, they felt they had learned valuable lessons last spring about the mental side of an NBA postseason series.

Jayson Tatum had 35 points, 10 assists and eight rebounds, and the Boston Celtics pulled away after Magic star Paolo Banchero went to the bench with five fouls, beating Orlando 120-89 in Game 5 of their first-round playoff series on Tuesday night to advance to the Eastern Conference semifinals.
