The Philadelphia 76ers have officially been eliminated from the 2020-21 NBA playoffs. They didn't even get a second to breathe before NBA Twitter started roasting their squad for falling well short of expectations. Add former Los Angeles Clippers forward and Atlanta Hawks star Josh Smith to their growing list of haters.

Smith blasted his one-time Clippers coach after the Sixers were ousted by the Hawks in Game 7. Watch the former NBA star's boisterous minute-long rant below:

Safe to say there's no love lost between the player and coach. Surprisingly, Smith played under Doc for less than one season with the Clippers. He didn't even finish the year with them, getting traded back to the Houston Rockets midseason.

There was possibly tension between the two given the fact that Smith only got 14.3 minutes of playing time through 32 games played for the Clippers. Prior to that, he had never had his playing time dip below even 27 minutes per game. Doc's Clippers infamously blew a 3-1 lead to the very same Rockets the year prior, featuring a heavy dose of Josh Smith in Games 6 and 7 of that stunning series upset.

That same postseason specter has followed Doc Rivers from his days in LA, now haunting him still with the Sixers. Josh Smith couldn't be more happy about it.
