NBA superstar LeBron James said Monday he was “heartbroken and devastated” over the death of Kobe Bryant, vowing in an Instagram post to continue Bryant’s legacy with the Los Angeles Lakers.

Bryant, a five-time NBA champion in 20 seasons with the Lakers, died Sunday at age 41 in a helicopter crash only hours after Lakers star James overtook him for third on the league’s all-time scoring list.

“I’m heartbroken and devastated my brother,” James posted. “Man I love you big bro.

Bryant retired in 2016, the same year James fulfilled his life dream of winning an NBA title with his hometown club, the Cleveland Cavaliers.

James led the Cavaliers into the NBA Finals the next two seasons, losing each time to Golden State, and in 2018 opted to leave Cleveland and join the Lakers.

This season, the Lakers have the second-best record in the NBA at 36-10 to lead the Western Conference, with James averaging 25.3 points, 7.7 rebounds and a league-best 10.7 assists a game.

The NBA postponed Tuesday’s scheduled Lakers game against the Los Angeles Clippers in the wake of Bryant’s tragic death.
