Richard Jefferson?s decision to opt out of the final $15 million season of his contract might not be a sign he?s willing to leave the San Antonio Spurs.

Sources said Spurs coach Gregg Popovich has been personally working out Jefferson in San Antonio

Richard Jefferson has opted out of the final season of his contract.

Jefferson would have earned $15.2M in the final year of his contract.

?It?s not an issue of not wanting to be in San Antonio," said Jefferson's agent Todd Eley to the Express-News. "It?s maximizing as many opportunities as you can."

Tony Parker is unsure if the Spurs will keep him beyond the current offseason.

?Everybody keeps telling me, ?Don?t go, don?t leave,? ? Parker told Yahoo! Sports on Wednesday while preparing to play in Steve Nash?s(notes) charity soccer game. ?I?m like, ?It?s not in my hands.? I don?t decide. I have one more year on my contract, so we?ll see what happens. Obviously because I have one year on my contract I will be in all the rumors. That?s normal.

?Hopefully, I will stay in San Antonio. If not, it?s a business.?

Parker?s preference would be to re-sign with the Spurs and stay in San Antonio, which he considers his ?home base.?

?I?m not nervous at all,? Parker said. ?I?ve had great years in San Antonio, so we?ll see what happens. Whatever San Antonio does, I?ll understand. It?s a business.

?I wish I can stay in San Antonio, but it?s not in my hands.?

The Spurs are widely expected to sign Tiago Splitter sometime soon after free agency opens on July 1.  

GM R.C. Buford categorizes the expectation as "presumptuous".

Splitter is now widely acknowledged as the best big man in Europe.

Splitter can expect a deal starting at the mid-level exception, about $5.5 million. He could make more money to stick around Spain, so the Spurs will likely have to make up the difference with a long-term contract.

One rival NBA executive surmises it will take five years and a total package worth between $25 million and $30 million to entice Splitter away from Spain's money.

"I've heard he's developed his game so much over the past couple of years," Manu Ginobili said Tuesday. "I'm dying to see him. I'd love to see him play with us."

Tony Parker says taking the summer off will help him when the NBA resumes play in September.

Parker isn't going to compete for France in the World Championship in Turkey this August.

"(This season) was the first time I've had a lot of little injuries," he said. "Next year I want to come back and be 100 percent for the season."

He hasn't worked out for a month and plans to take two more weeks off.

"It's a good change because usually I get two weeks and then I go to the national team," Parker said.

Gary Woelfel of the Journal Times writes that the Spurs are interested in moving up in this month's NBA Draft in order to take North Carolina's Ed Davis.

San Antonio has the 20th pick and Woelfel adds that they are trying to acquire the 10th selection from Indiana.
