The Spurs entered the Draft with their two original picks. They used the 20th overall pick to select James Anderson, junior guard from Oklahoma State. Anderson had been named the Big 12 Player of the Year and a Second Team All-American by the Associated Press, averaging 22.3 points, 5.8 rebounds, 2.4 assists and 1.4 steals in 33 games. With the 49th pick the Spurs chose Ryan Richards, a 6-11 forward from England. The Spurs went on to sign Anderson on July 23.

Entering the offseason, four Spurs players were unrestricted free agents: Keith Bogans, Matt Bonner, Ian Mahinmi and Roger Mason. Additionally, Richard Jefferson exercised the early termination option on the final year of his contract and he too became an unrestricted free agent. Jefferson, however, re-signed with the Spurs to a less remunerative but longer deal shortly after. The Spurs also re-signed Bonner, which was considered a top priority by general manager R.C. Buford, while Bogans, Mahinmi and Mason signed with the Chicago Bulls, the Dallas Mavericks and the New York Knicks respectively. Following his performances as a member of their Summer League squad in July, when he led the team in scoring, the Spurs signed free agent Gary Neal. The 6-6 guard had gone undrafted in the 2007 NBA draft and spent the next three season playing in Europe.
