33. Danny Ferry
Like Steve Smith, Danny Ferry was also older when he joined the Spurs. Luckily, he retired as a champion, scoring 20 points in the 2003 postseason to help them win their second NBA title. Ferry finished his career with 123 playoff points in San Antonio.
32. Antonio Daniels
It only took two seasons before Antonio Daniels could call himself an NBA champion. While his role on the 1999 squad was limited in the playoffs (27 points, 16 assists in 15 games), his later body of work for Spurs basketball lands him at number 32.
31. Jacque Vaughn
Jacque Vaughn was never the type of player to have monster games, but he was a reliable backup point guard in the Spurs' 2007 run. Save for one bad game against Phoenix, he only turned the ball over seven times in the other 19 playoff games he showed up in and scored 43 points that postseason.
30. Jerome Kersey
Joining the Spurs at age 36, Jerome Kersey was yet another veteran fortunate enough to join the team right as they were about to win their first championship. Putting up 36 playoff points and pulling down 30 playoff boards is no small feat, earning him a top-30 spot on the list.
29. Cory Joseph
One of many solid backup point guards the Spurs had in their championship runs, Cory Joseph eventually earned himself a bigger payday with Toronto after winning a title in San Antonio in 2014. Joseph turned the ball fewer than 2.5 times per 100 possessions in his four seasons with the San Antonio. That's all you really need to do when playing behind Tony Parker.
28. Kevin Willis
Entering the league in 1984, Kevin Willis had to wait 19 whole years before he'd taste an NBA championship. It took him joining the Spurs in 2003 to get there. Willis contributed 46 points and 31 rebounds in that postseason run at the age of 40. He remains one of the oldest players to ever play in an NBA game, retiring with the Dallas Mavericks in 2007 at nearly 45.
