Doc Rivers Adds Sam Cassell to Philadephia 76ers Coaching Staff

Former NBA player Sam Cassell will join the Philadelphia 76ers' coaching staff, a source confirmed to Sports Illustrated on Wednesday. Cassell, a former NBA veteran who spent 16 seasons in the league, got his start as a coach in 2009 after wrapping up a one-year playing stint with the Boston Celtics.

Cassell's first gig as an assistant coach came with the Washington Wizards, where he reunited with then-head coach Flip Saunders. After coaching with Washington from 2009 to 2014, Cassell transitioned to the Los Angeles Clippers' bench, where he joined Doc Rivers' staff ahead of the 2014 NBA season. 

For the last six years, Cassell has been one of Rivers' top assistants. Cassell began to garner some interest with multiple head coaching jobs becoming available around the league this year. The veteran assistant even interviewed for the Los Angeles Clippers' vacancy after they fired Doc Rivers.

However, Rivers' former assistant Ty Lue ultimately won the job. While the chances of Cassell remaining in LA were high -- the three-time NBA Champion will follow Rivers to Philadelphia. According to The Philadelphia Inquirer's Keith Pompey, the expectation all along was the 76ers were going to bring on Cassell unless he signed on with another team as a head coach.

Cassell now becomes the fourth-newest coach on Rivers' staff this offseason. A couple of weeks ago, Rivers and the Sixers brought on former Sacramento Kings head coach Dave Joerger. And on Wednesday, the Sixers also added former Indiana Pacers assistant Dan Burke along with former Clippers head video coordinator Pete Dominguez.
