After 19 seasons and five NBA titles, one of the NBA's greatest all-time players is calling it quits.

San Antonio Spurs' power forward Tim Duncan announced today he is retiring from the NBA.

Duncan helped lead the Spurs to five NBA titles during this time with the club.  The Spurs compiled an overall record of 1,072-438 during his tenure and played at least .600 ball in each of his nineteen seasons.  He was named NBA Finals MVP three times.

Duncan was the #1 overall pick in the 1997 draft and was named Rookie of the Year.  He helped lead the Spurs to their first championship the following season.  Over his career, he averaged 19 points, 10.8 rebounds, three assists and 2.2 blocks per game.

Only Kobe Bryant (20) spent more time with one team in his NBA career.
