|Oklahoma City Thunder|
Sam Presti (born c. 1976 in Concord, Massachusetts) is an American basketball executive. Since June 7, 2007, he has been the General Manager (GM) of the Oklahoma City Thunder. In the summer of 2010, the team extended his contract.
Presti previously served in several progressively more significant positions for the San Antonio Spurs after beginning as an intern. He met their General Manager R. C. Buford at a basketball camp in Aspen, Colorado. He is given much of the credit for encouraging the Spurs to draft point guard Tony Parker in 2001.
In his first move as GM of the Sonics, he traded multiple-time All-Star Ray Allen to the Boston Celtics, whom Allen helped win the NBA title in 2008, in a large trade that included the draft rights to Jeff Green. He shortly thereafter traded All-Star Rashard Lewis to Orlando for a second-round draft pick, generating a 9-million-dollar trade exception which Presti later used to land Kurt Thomas and two first-round draft picks from Phoenix. To lead the team, he selected as head coach P. J. Carlesimo, whom he knew as an assistant coach at San Antonio. In Presti's first season in charge, the team was 20–62, the worst in the history of the franchise. Toward the end of that season, the league authorized a move and after a court battle and settlement, the team was allowed to move to Oklahoma City, Oklahoma. Subsequently, they were renamed the Thunder.
During his second season, the Thunder began the season 1–12 and Presti fired Carlesimo, and hired assistant coach Scott Brooks as the interim coach. Under Brooks, the Thunder went 22–47. Presti acquired Thabo Sefolosha from the Chicago Bulls for a late first-round pick. Presti also initiated a trade for Tyson Chandler from the New Orleans Hornets for two backups (Chris Wilcox and Joe Smith), but the trade was later rescinded because Chandler failed his required physical.
Coach Brooks was retained and in Presti's third season the plan began to provide much improved results. A strong defense arose with the help of Assistant Coach Ron Adams. Kevin Durant, whom Presti drafted in 2007, became the league's leading scorer and other higher draft picks obtained in the previous weak seasons and a few veterans successfully filled roles and improved the team's record to 50–32. The Thunder played the eventual champion Los Angeles Lakers in the first round, forcing them to six games before losing, 4–2.
On October 28, 2012, after unsuccessfully negotiating a contract extension, Presti traded reigning Sixth Man of the Year James Harden, along with Center Cole Aldrich and forwards Daequan Cook and Lazar Hayward to the Houston Rockets for guards Kevin Martin, Jeremy Lamb, two first-round picks and a second-round pick. This was widely regarded as a poor decision and, following Harden's breakout season in Houston, has been suggested by sports journalists to be one of the most one-sided trades in the modern NBA.
