Doc Rivers has stepped down as coach of the LA Clippers in what chairman Steve Ballmer called a “mutual decision.”

The team fell well short of its championship expectations this season after acquiring All-Stars Kawhi Leonard and Paul George last summer in what were NBA-altering moves.

“Doc has been a terrific coach for the Clippers, an incredible ambassador, and a pillar of strength during tumultuous times,” Ballmer said in a statement Monday. “He won a heck of a lot of games and laid a foundation for this franchise.”

Rivers had two years left on his contract, sources told ESPN’s Adrian Wojnarowski.

The Clippers went 49-23 in the regular season, the fourth-best record in franchise history, but squandered a 3-1 series lead in the Western Conference semifinals against the Denver Nuggets, surrendering leads of 16, 19 and 12 points as the franchise’s Western Conference finals drought reached 50 years. Rivers has been the coach in five of the Clippers’ six best regular seasons.

Rivers is the only coach in NBA history to lose a 3-1 lead in three playoff series, having done so with the Clippers in the 2015 West semis against the Houston Rockets and with the Orlando Magic in the first round against the Detroit Pistons in 2003.
