The New York Knicks already were going to be well-represented on Team USA at the FIBA World Cup later this summer, and now small forward RJ Barrett officially is going, too.

Barrett averaged 19.6 points and 5.0 rebounds in 73 games for the Knicks last season, and 19.3 points and 4.5 boards in 11 postseason contests.
