Sam Presti | Executive Vice President & General Manager

Sam Presti enters his eighth season with the Oklahoma City Thunder after being named the 11th General Manager in club history on June 7, 2007. A year into his tenure with the Thunder, Presti was promoted to Executive Vice President and General Manager by Professional Basketball Club Chairman, Clayton Bennett.

During his seven-plus seasons with the Thunder, Presti has worked diligently to assemble the building blocks for long term success both on and off the court. This past season, Presti and his staff oversaw a fourth straight Northwest Division Championship as the Thunder finished the year with the second best record in the NBA. The Thunder’s four straight division titles are tied for the longest such current streak in the NBA and over the last 25 seasons only two teams have ever gone onto capture more than four consecutive division titles.

After finishing the 2013-14 regular season with a record of 59-23, the Thunder became one of just two teams (San Antonio) to register a winning percentage of .610 (equivalent to 50 wins) in each of the last five seasons.

Presti’s consistent focus has been to utilize the NBA Draft to establish the foundation for sustained success on the floor and in the community. Commencing with the 2007 draft, Presti selected Kevin Durant, the University of Texas standout with the team’s No. 2 overall pick. This past season, Durant was named the NBA’s Most Valuable Player after leading the NBA in scoring for a fourth time in the past five seasons.

Other significant draft selections for Presti include taking Russell Westbrook and Serge Ibaka with the 4th and 24th selections, respectively in the 2008 draft. Westbrook has since become a three-time All-Star, and Serge Ibaka became just the second player in NBA history to lead the NBA in blocks for four consecutive seasons (2010-2014). Most recently, Steven Adams was named to the All-Rookie Second Team after being selected by the Thunder with the 12th overall pick in the 2013 NBA Draft.

After moving to Oklahoma City in July of 2008, Presti has stressed the importance of community involvement for both Thunder players and staff. Under his leadership, Thunder players have made nearly 1,500 community appearances in and around Oklahoma City. Presti has also made it policy for every new player and staff member to tour the Oklahoma City Memorial and Museum soon after joining the organization.

Under Presti’s guidance, the Thunder has advanced to postseason play in each of the last five seasons. At the end of the 2012-13 season, Oklahoma City became just the second team in NBA history (Boston Celtics; 1955-1960) to increase its winning percentage for five consecutive seasons (while maintaining a winning percentage of .700 or better in two of those seasons). Dating back to the 2011-12 season, the Thunder became Western Conference Champions on the heels of the 2010-11 season in which the Thunder became the youngest team in the prior quarter century to reach the NBA’s Western Conference Finals.

During the 2009-10 season, Presti’s third year at the helm, Oklahoma City experienced one of the largest turnarounds in NBA history. A year after winning 23 games, the Thunder concluded the 2009-10 season with a 50-32 record (.610) and captured the franchise’s first playoff berth in Oklahoma City. The 27-win improvement was tied for the eighth largest improvement in NBA history. Presti was named NBA Executive of the Year by The Sporting News at the conclusion of the season.

Presti has been on the NBA’s Instant Replay Committee since 2009 and has served on the league’s Competition Committee dating back to the 2011-12 season.

Prior to joining the Thunder, the 37-year-old Presti held a variety of roles with the San Antonio Spurs. After starting in 2000 as a video intern for Gregg Popovich, Presti moved up through the front office ranks in San Antonio before being elevated to the position of Vice President and Assistant General Manager. As a member of the Spurs, Presti was part of NBA Championship teams in 2003, 2005 and 2007, as well as five division titles.

Presti earned his bachelor’s degree in 2000 in communications, politics and law and a minor in psychology from Emerson College in Boston, where he was the first Rhodes Scholar nominee in school history. The Concord, Mass. native served as team captain of the Emerson College basketball team during both his junior and senior seasons. In addition, Presti earned All-Academic honors two times and was twice selected to the Great Northeast Athletic Conference All-Tournament team. He was honored with the Emerson College Young Alumnus Award in 2005. Presti also completed Harvard University’s Continuing Education program on leadership and decision making this past offseason.

Presti currently resides on the board of the Oklahoma City National Memorial and with the support of the Thunder has established the Forward Thinking Leadership Development Program within the Oklahoma City public schools. Presti was recognized as Oklahoma City University’s 2012-13 recipient of the Abe Lemons/Paul Hansen Award for Sports Excellence and also won the Oklahoma March of Dimes Sports Headliner Special Award for 2013.

Additionally, Presti is actively involved with PeacePlayers International (PPI), a global outreach program focused on bringing children and communities together through the game of basketball. He also serves on the Board of Directors of Shooting Touch, an organization that grants graduating college seniors the opportunity to travel the world and use the platform of basketball to help foster education and influence positive social change in third world global communities.

An accomplished drummer, Presti has produced three music CDs with all proceeds benefiting the Extra Ordinary Needs Fund at Children’s Hospital in Boston. Also, Presti established the Keenan Smith-Anthony Halls Scholarship Fund at his former high school, Concord-Carlisle, to assist students with their college tuition.

Presti’s wife, Shannon, serves as the Director of Teen Leadership Initiatives for the YMCA of Greater Oklahoma City.

Troy Weaver | Vice President/Assistant General Manager

Troy Weaver begins his seventh season with Oklahoma City and his fifth as the team’s Vice President/Assistant General Manager. Weaver joined the Thunder in May of 2008 and assists General Manager Sam Presti with roster development and day-to-day basketball operations. In addition, he coordinates the team’s player personnel matters including NBA Draft preparation, player free agency and summer league roster.

Weaver held the position of director of player personnel for the Utah Jazz in 2007-08. He spent three seasons (2004-07) as head scout for the Jazz before his promotion to director of player personnel.

Prior to joining the Jazz, Weaver was an assistant coach at Syracuse University for four seasons (2000-04). The Orangemen won the 2003 NCAA National Championship led by Weaver recruit Carmelo Anthony. In addition to his experience at Syracuse, Weaver spent time as an assistant coach at New Mexico (1999-2000) and Pittsburgh (1996-99).

Prior to his collegiate coaching days, Weaver amassed an 85-17 record as an AAU coach in Washington, D.C. He guided the DC Assault to the 1996 AAU Tournament of Champions.

Weaver graduated with an associate’s degree from Prince George’s Community College (MD) in 1991, where he also played one season of basketball.

Michael Winger | Assistant General Manager & Team Counsel

Prior to joining the Thunder, Winger spent five seasons (2005-06 through 2009-10) in the front office with the Cleveland Cavaliers, earning several promotions during his tenure. Winger began his career in Cleveland as its Basketball Operations Coordinator. Winger was promoted to Basketball Operations Manager / Team Counsel, and shortly thereafter to the Cavaliers’ Director of Basketball Operations & Team Counsel. Winger’s role in Cleveland was extensive, and included instituting organizational processes and working closely with Cavaliers’ management and ownership on all team matters. He joined the Cavaliers in July of 2005 after spending two years working for renowned sports agent and attorney, Ron Shapiro in Baltimore, Maryland.
