Suffice it to say there is no love lost between Josh Smith and Doc Rivers.

Smith, who played under Rivers with the Los Angeles Clippers in the 2015-16 season, ripped the Philadelphia 76ers coach in an Instagram video (warning: explicit language) after his team was eliminated by the Atlanta Hawks in the second round.

"Yeah, Doc Rivers, you talked all that s--t about Paul George and how Tyronn Lue was going to have the same offense for that n---a. Shut your bum ass up, man. Your no-in-game-adjustments-havin' ass, man," Smith said Sunday via Instagram. 

"Start giving n---as their real credit, man. That’s why your b---h ass got that karma on your ass and you can’t get past the second round. You did all these real n---as wrong, man. Look in the mirror, n---a, and confess your motherf--kin' truth, or you'll never make it out of the second round."

This is not the first time Smith has reveled in Rivers' postseason failures. He ripped Rivers after the Clippers blew a 3-1 lead in the second round of the 2020 playoffs, which led to Rivers' dismissal in Los Angeles.

While Rivers was the architect of the 2007-08 NBA champion Boston Celtics, his playoff resume is otherwise littered with disappointment.

ESPN Stats & Info noted Rivers has lost 29 games with a chance to close out a playoff series as a head coach, the most in history. His .349 winning percentage in those games is also an NBA-worst stat.
