Timberwolves would not qualify for the postseason again until 2018. Cassell appeared to have found a home with the Clippers, as he helped lead them back to the playoffs for the first time since 1997, with their best record in team history at 47–35. Since the team moved to California in 1978, they had compiled just three winning seasons. In the first round, they beat the Denver Nuggets in five games, but would fall to the Phoenix Suns in seven games in the Conference Semifinals. Between their move to California in 1978 and Chris Paul's arrival in 2011, this would be the only year that the Clippers won a playoff series. Before the 2006–07 season, Cassell was reportedly offered a two-year, $15 million offer from the Atlanta Hawks, but eventually re-signed with the Clippers on a two-year, $13 million deal.

Cassell said that he would wear either No. 28 or No. 91 on his jersey, and eventually chose No. 28. According to his agent, Cassell had signed a contract with the Celtics on March 3, 2008, but the signing was pending an official league announcement.
