The Los Angeles Clippers interviewed assistant Sam Cassell for their head coaching job on Oct. 13, according to Adrian Wojnarowski.

Cassell has spent six seasons on Doc Rivers’ staff.

Cassell, 40, began his coaching career with the Washington Wizards after he retired from playing in 2009.

He spent five seasons with the Wizards as an assistant before joining the Clippers in 2014.

Rivers endorsed Cassell as a deserving NBA head coach last month.

“Sam Cassell should be a head coach, period. He’s got an incredibly high basketball IQ, and I just hope he gets a shot,” Rivers said. “He’s paid every due that’s possible. When they talk about paying dues, he’s paid every due that is possible and he’s yet to get a job. So, I’m hoping that happens.”

The Clippers also have interest in Tyronn Lue, Mike Brown, Darvin Ham and Wes Unseld Jr.

Cassell has also drawn interest from the Houston Rockets, although he hasn’t reportedly interviewed with them.

If he doesn’t ultimately get a head coaching job, it will be interesting to see if Cassell remains an assistant with the Clippers, joins Rivers as an assistant with the Philadelphia 76ers or ends up on another team’s staff.
