3. David Robinson, 2003 - 2 NBA Championships
David Robinson certainly deserved a title or two in San Antonio before he called it a career. Thanks to the arrival of Tim Duncan, that was finally made possible a couple of times. The Admiral had come close to leading the Spurs to a title before, most notably in his 1995 MVP season before running into Hakeem Olajuwon. Unfortunately, he never quite had enough help to get over the hump.
It only took two years of the Twin Towers being formed before they were both able to call themselves NBA champs, and their success didn't end there. Like Kerr, Robinson was also 37 in his final season with San Antonio. Of course, the difference is he was a full-time starter throughout the postseason run.
Robinson's swan song was loud and powerful, as he put up 13 points and pulled down a monstrous 17 rebounds in the final game of his NBA career. He and the Spurs were crowned champions a second time.
4. Tony Massenburg, 2005 - 1 NBA Championship
Drafted 43rd overall in 1990, Tony Massenburg began and ended his 13-year career in San Antonio. It's safe to say he's glad the Spurs were the bookends to his career. After 12 years of being unable to capture NBA glory, he was able to win one in his final season at the age of, you guessed it, 37.
Massenburg had his moments in the 2005 season -- notably his two 16-point, eight-rebound performances against Sacramento and Denver. At the end of the bench on the postseason roster, Tony only had a handful of playoff minutes. Still, he was able to retire on top with his last NBA game taking place on June 16, 2005.
