The Memphis Grizzlies have explored center Greg Oden, expressing interest in the recent past with a workout in the spring, and will potentially bring in the former No. 1 overall NBA pick to a free-agent camp in June, league sources told RealGM.

Oden, the first overall selection to the Portland Trail Blazers in 2007, played with the Miami Heat last season. He scored 67 points and grabbed 54 rebounds in 23 games.

The Grizzlies’ current level of interest in Oden remains unclear, but the franchise is believed to be having a free-agent mini-camp in the upcoming weeks -- like many organizations around the NBA. Oden is undecided in his possible participation there.

Oden's close friend and former teammate, Mike Conley, spoke late this season about the possibility of the seven-footer's comeback. Surely, Oden’s comfort level with the Grizzlies rises with Conley’s stature on the team.

In averaging 15.7 points and 9.6 rebounds, Oden led Ohio State to the NCAA championship game in 2007 and had the base of a foundational player at the NBA level. Nevertheless, knee injuries provided constant setbacks.

Oden, 27, has played two NBA seasons for Portland and one for Miami.

Marc Gasol is expected to be pursued in free agency by the San Antonio Spurs.

Gasol's free agency plans have remained a mystery and the common expectation has been he would re-sign with the Memphis Grizzlies.

"I'm a free agent, but I still have not raised anything," said Gasol of his future. "In the next few weeks, I will begin to speak with different franchises. My brother has not advised me about the different possibilities, but the decision will be complicated. My family spends time in Memphis and has even worked in the Saint Jude Hospital."

"San Antonio is an example franchise and I've always admired Tim Duncan," said Gasol. "But we'll see in the summer. "

The Spurs can create maximum contract cap space.

Nick Calathes has denied a report from Spain that claimed he wants out of the NBA and has been offered to Barcelona.

"The NBA is my first priority," Calathes said.

Calathes will be a restricted free agent this summer after two seasons with the Memphis Grizzlies.

Calathes previously spent four years in Europe.

Kawhi Leonard, Draymond Green, Tony Allen, DeAndre Jordan and Chris Paul have been named to the 14-15 NBA All-Defensive First Team.

Leonard, Green and Jordan are all on the First Team for the first time in their career.

On the All-Defensive Second Team are Anthony Davis, Jimmy Butler, Andrew Bogut, John Wall and Tim Duncan.

Rudy Gobert headlined the list of players also receiving votes along with LeBron James, Russell Westbrook and Avery Bradley.

Leonard received 116 of 129 first team votes, followed by Green with 107 and Tony Allen with 88.

Bogut receives a $1.945 million bonus for being included on the Second Team.

The San Antonio Spurs, Los Angeles Lakers, New York Knicks and Dallas Mavericks all are developing proposals to present to Marc Gasol on July 1, according sources.

Gasol averaged 17.4 points, 7.8 rebounds, 3.8 assists and 1.6 blocks while shooting 49.4 percent from the field in 81 games this season.

"He's the best player at his position in the league," Grizzlies coach Dave Joerger said. "You make preparations if it goes in a direction you're not happy about. You're not going to lose sleep at night. It's not going to do any good. He's going to do what he's going to do. Not in the next two weeks are we going to send him a big thing of flowers and it's going to change his mind. [By then], the cement is dry.

"We'll make our last, 'Hey, this is what's important to us. What's important to you?' Things of that nature. But I've got to think his mind is 99 percent made up."

While the San Antonio Spurs will certainly pursue Marc Gasol, they're expected to initially focus on LaMarcus Aldridge.

The plans of Marc Gasol remain a mystery to even those closest to him, while there's been several indications that Aldridge will at least strongly consider leaving the Portland Trail Blazers.

Gasol and Aldridge have each spent their entire career with the Grizzlies and Blazers respectively.

The Memphis Grizzlies are interested in signing an extension with Mike Conley and have engaged in talks more than once.

Conley will become a free agent in 2016, when his five-year, $40 million deal expires.

Conley would draw significant interest as a free agent at 28 years old.

With the cap increasing in 2016, Conley would likely fare much better financially by waiting for a new deal.

Marc Gasol will be a free agent this offseason, but he hasn't begun considering his decision after the Memphis Grizzlies were eliminated from the playoffs on Saturday.

"I haven't even spent a second thinking of that," he said. "I'm drained right now. I couldn't pull it out for my teammates tonight. I gave it all I had."

Gasol has played for the Grizzlies throughout his NBA career.

Tony Allen said he will play in Game 6 despite his hamstring injury.

Allen sat out the Memphis Grizzlies' Game 5 loss at the Golden State Warriors.

Allen has made a huge impact on defense for the Grizzlies in their two victories in the series.
