The 2003–04 NBA season was the Clippers' 34th season in the National Basketball Association, and their 20th season in Los Angeles. During the offseason, the Clippers signed free agents Bobby Simmons and former All-Star forward Glen Rice. However, after 18 games, Rice was released. With the Clippers starting from scratch again as they celebrated their 20th season in L.A., they hired Mike Dunleavy, Sr. as their new head coach. Under Dunleavy, the Clippers played slightly around .500 with a 22–25 start as of February 6. However, after co-hosting the 2004 NBA All-Star Game at the Staples Center with the Lakers, the young Clippers struggled badly as they won just six games, and posted a 13-game losing streak near the end of the season. The Clippers would slowly sink down the standings, coming to rest once again at the bottom of the Pacific Division with a 28–54 record. Following the season, Quentin Richardson signed as a free agent with the Phoenix Suns.
