The 2019 Raptors set a new record Tuesday by surpassing the previous title reign of 390 days that the 1981 Boston Celtics established, according to CBS Sports' Samuel Quinn.

Today, the 2019 Toronto Raptors officially become the longest-reigning champions in NBA history. They have held the title for 391 days.

The previous record of 390 was set by the 1981 Celtics, as the NBA pushed the start of the playoffs from April 1 to April 21 in 1982.

Quinn explained that while there have been three-peat champions in the NBA, each individual team within the dynasty is considered distinct due to roster and coaching changes.

The Raptors were second in the Eastern Conference with a 46-18 record when the NBA season was suspended in March. Play is set to resume later this month.
