The historic NBA rivalry between the Boston Celtics and Los Angeles Lakers has extended to USA Basketball. Team USA is in Melbourne preparing for its pre-2019 FIBA World Cup exhibition games against Australia beginning Thursday night, and several players from the Celtics and Lakers are still with the Red, White and Blue squad. Celtics forwards Jaylen Brown and Jayson Tatum, as well as Lakers forward Kyle Kuzma all got in some extra practice by playing 1-on-1 against each other this week.
