Tim Duncan announcing that he will be retiring after 19 seasons in the NBA. The 40-year-old leaves the game having won five titles. The San Antonio Spurs were a model of consistancy during his time in the Alamo City, making the playoffs in all 19 of his campaigns.

Tim Duncan retires after 19 seasons with Spurs

Duncan, together with Tony Parker and Manu Ginobili, formed one of the NBA's most successful trios. They hold the league records for regular season wins with 575, and postseason victories with 126.

Duncan, will leave the game as one of the top-15 players of all-time, and some consider him the greatest power forward ever. He is a three-time Finals MVP and a two-time regular season MVP, and led San Antonio to five titles. The first came in 1999, and the last in 2014. The Spurs posted a 1,072-438 regular-season record since drafting Duncan -- the best 19-year run in league history.

He was a model of consistency, but became less effective this past season, statistically his worst campaign ever. He was almost a non-factor in San Antonio's second round playoff series against OKC, which they lost in six games. In his final game he scored 19 points, grabbed five rebounds, and tallied one block in 34 minutes. Duncan will be a unanimous first ballot Hall of Famer when he is up for election.
