Ginobili and Parker this year said goodbye to Spurs big man Tim Duncan, whose retirement breaks up San Antonio's "Big Three."
"A lot of emotions. It is always tough when it finally happens," Parker said.
"Those 15 years with Tim, all the success we had, I am just happy Manu has got one more year."
LeBron longs for more Games glory
Three-time NBA Finals MVP LeBron James said he is keeping his options open for a return to Team USA for the 2020 Tokyo Olympics.
"I did not retire from Team USA," he told US sports network ESPN on Wednesday. "I just did not play this summer. I left the door open."
Team USA advanced to the semifinals of the men's basketball tournament with a convincing 105-78 rout of Argentina on Wednesday.
A 12-time NBA All-Star, James chose to skip Rio because he said he needed to rest after a long season.
"But every time I watch them, I wish I was out there," he said.
The 31-year-old won two gold medals with Team USA in London and Beijing. He was also on the 2004 US team that lost three games in Athens, settling for a bronze.
James guided his team to the NBA Finals in each of the past six seasons.
He returned to Cleveland from the Miami Heat ahead of the 2014-15 campaign and led the Cavaliers to the Finals in both seasons since then.
Cleveland lost to the Golden State Warriors in the 2015 finals before beating the Warriors in the rematch for the first championship in franchise history.
Last week, James signed a three-year contract wort/100 million, making him the NBA's highest-paid player for the first time in his career.
He has said he would like to own his own team someday. "I would love to be a part of a franchise, if not at the top," James said on the website Uninterrupted. "My dream is to actually own a team.
"If I am fortunate enough to own a team, then I am going to hire the best general manager and president I can," he added. "But I feel like I have a good eye for not only talent, because we all see a lot of talent, but the things that make the talent."
James averaged 25.3 points, 7.4 rebounds and 6.8 assists in 76 games last season. In the postseason, his averages improved to 26.3, 9.5 and 7.6, respectively.
