Later Friday night, the Hawks clinched East Group C in the NBA Cup when Chicago lost to visiting Boston.

The Cavaliers (17-3) still boast the NBA's best record, but they once again couldn't match the Hawks' scoring depth. Trae Young had 21 points and 11 assists and Jalen Johnson added 17 points, nine rebounds and seven assists as Atlanta finished with six scorers in double figures.

Darius Garland led Cleveland with 29 points and Evan Mobley contributed 24 points, including seven dunks.

He is also the second player in the past 30 seasons to average 20 points and 15 assists in a two-game span against the team with the best record in the NBA. He joins Chris Paul in 2009 against the Los Angeles Lakers.

Led by Hunter, Atlanta's bench outscored Cleveland's reserves 50-28.
