The Dallas Mavericks have acquired Kelly Olynyk and Derrick Jones from the Miami Heat as part of the Jimmy Butler sign-and-trade with the Philadelphia 76ers.

Ramona Shelburne of ESPN previously reported Goran Dragic would go to the Mavericks. The Mavericks couldn't take back Dragic because they feared losing their flexibility to make additional moves this offseason.

The Dallas Mavericks had agreed to acquire Goran Dragic from the Miami Heat as part of the Jimmy Butler sign-and-trade with the Philadelphia 76ers, according to ESPN's Ramona Shelburne.

The Heat needed to send out additional salary to absorb Butler.

But Marc Stein of the New York Times reports that the Mavericks will instead acquire Kelly Olynyk and Derrick Jones.

Danny Green and the Dallas Mavericks have mutual interest in free agency.

It is believed Green wants to wait for Kawhi Leonard's decision before committing.

Green was traded by hte San Antonio Spurs to the Toronto Raptors last offseason.

Kristaps Porzingis and the Dallas Mavericks have agreed to a five-year, $158 million contract.

The Mavericks acquired Porzingis from the New York Knicks at the deadline.

Tim MacMahon of ESPN reports that the deal is fully guaranteed and the Mavericks didn't push for any game minimums to protect for injury.

The Dallas Mavericks plan on offering Dwight Powell a three-year, $33 million contract in free agency.

The Mavericks and Powell are expected to quickly agree to the deal.

Dallas has made Powell one of their priorities this offseason.

There are a few surprise bidders for Al Horford in free agency.

While Horford has been linked with the Dallas Mavericks and New Orleans Pelicans, the Sacramento Kings and Philadelphia 76ers are also potentially interested.

The Kings could re-sign Harrison Barnes and also sign Horford.

Philadelphia has several free agents of their own in Tobias Harris, Jimmy Butler and J.J. Redick.

Patrick Beverley is seeking a three-year, $40 million deal in free agency.

Beverley will receive interest from the Dallas Mavericks, Los Angeles Lakers, Chicago Bulls and the incumbent Los Angeles Clippers.

Beverley is represented by Bill Duffy, who is also the agent of Luka Doncic.

The Boston Celtics have emerged as the frontrunners to sign Kemba Walker in free agency.

Shams Charania of The Athletic reports that the Charlotte Hornets and Walker have "sizable gaps and (a) stalemate in talks so far, opening (a) pathway for competitors in Boston, New York and Dallas."

Walker is eligible for a supermax contract with the Hornets, but that has always been an unlikely scenario.

Adrian Wojnarowski reported on the Thursday evening SportsCenter that the Celtics are "more than a strong frontrunner (for Walker). They are in position to sign him when the moratorium ends on July 6th. They could have a commitment as soon as Sunday night."

Stephen A. Smith reported that Walker had planned to sign with the Celtics, but he could be considering the Lakers now that they have enough space for his max. 

"According to my sources, he told the Charlotte Hornets that he wants out and that he planned on going to the Boston Celtics, but that was before the Los Angeles Lakers created this additional cap space," said Smith.

The Dallas Mavericks will attempt to pursue Kevin Durant in free agency.

Mark Cuban, like many in the NBA, has long coveted Durant.

The Mavericks are expected to also sign Kristaps Porzingis to a long-term deal this offseason, which would give Durant a stable foundation along with Luka Doncic.

The Mavericks took on Tim Hardaway Jr. and Courtney Lee in order to acquire Porzingis, which limits their cap space, but they could fairly easily create enough space to sign Durant.

It is not yet clear if Durant will meet with the Mavericks.

The Los Angeles Clippers could express interest in Tobias Harris if they are unable to agree to terms with Kawhi Leonard, sources tell Shams Charania of The Athletic.

The Dallas Mavericks, Memphis Grizzlies and New Orleans Pelicans are also expected to pursue Harris.

The Philadelphia 76ers are also making re-signing Harris a priority.

Harris is expected to command a max contract.
