The San Antonio Spurs are said to be "head over heels with" Kristaps Porzingis.

If the Spurs were to trade Kawhi Leonard to the New York Knicks, they would require Porzingis and a first round pick back for him.

Porzingis is recovering from a torn ACL and will become eligible for an extension this offseason.

The Miami Heat are expected to pursue a trade of Hassan Whiteside this offseason.

Whiteside is due $24.4 million and $27.1 million in the final two years of his contract.

"It's been a long year, man, up and downs, up and downs," he said.

Whiteside has talked openly about his frustrations with playing time.

"Not being out there,” he said. “Not being out there. At least give me a chance to fight. At least give me a chance to fight. I can understand if I was playing 30 minutes and I played bad. At least give me a chance."

He said: “We played a style of play Coach wanted. He wanted to utilize more spacing I guess in the playoffs, so that's why he did it."

The San Antonio Spurs hope to have an "all-hands-on-deck" meeting with Kawhi Leonard this offseason, according to sources.

The Spurs plan on meeting with Leonard to gauge whether they two sides can continue their partnership. Gregg Popovich is expected to take the lead.

"Kawhi, everybody asks questions, but he's still here," Danny Green said. "He's still locked in. He's a part of the team until things change."

Leonard missed all but nine games this season due to a quadriceps issue. Leonard has sought extra time rehabilitating in New York.

The decision on whether to offer Leonard a five-year, $219 million supermax extension will be determined by management, current players and ownership. R.C. Buford could have a difficult time convincing Peter Holt and Julianna Hawn Holt, who are undergoing a divorce, that they should offer the extension.

Wojnarowski expounded upon his story during a SportsCenter appearance. 

"The relationship between Kawhi Leonard and the Spurs is broken and it's got to be put back together again before the Spurs make that kind of commitment to a player," said Wojnarowski.

LeBron James could become a free agent this offseason but he could also control his destiny in another way by orchestrating an opt-in-and-trade similar to Chris Paul last offseason.

On The Lowe Podcast, Brian Windhorst talked about a scenario in which James could have an extended period of time to work on his offseason plans if the Cavaliers are eliminated from the playoffs before the Finals.

"All I'm going to say is you don't want LeBron to have two months to plot with other players," said Windhorst. "Because, you know, Chris Paul and James Harden have now written the script. While the Finals are going on, if you're not in them, let's just get together in L.A. and plot how you're going to get together. You know, we've gotten in the point in the league where the players have so much power. They can force trades."

When James was a free agent in 2010, the Cavaliers were eliminated in the second round on May 13th.

"LeBron has an option in his contract. I hear people talking about, 'Will it be the "akers?' They go through the four teams with cap space. 'Will it be the Sixers?' If LeBron deems it, he will go to the Cavs, 'You will trade me to team X' and as long as that team isn't trying to force Luol Deng down the Cavs' throat, the Cavs will do the deal because they won't want to lose him for nothing. Just like how the Clippers did not want to trade Chris Paul, but at the end of the day, the alternative was unacceptable.

"If LeBron is left to his own devices and not focused on playing basketball for two months, and he can take meetings with everybody in the league: forget about July 1st, forget about the teams that are going to pitch him. The meetings are going to go down in May and June if LeBron is out of the playoffs. Now, if LeBron is not out of the playoffs and the Cavs get all the way to the Finals, that changes the game quite a bit. 

"We're going to get down to June 29th, that's when LeBron's option date is. In fact, whenever the draft is, the Cavs are going to like, you know, be like, 'LeBron, what are we going to do here?' I don't even know if this is even going to get to July. This could all get mitigated out in June."

At least one NBA executive believes the Los Angeles Lakers will pursue a trade for Kawhi Leonard this offseason and that he would like to play in the area he grew up.

Leonard would give up an opportunity to sign a supermax contract extension if he decides he wants to leave the Spurs.

“I think they go in hard for Leonard once the season is over and once the dust settles in San Antonio,” one executive told Sporting News. “(Leonard) wants to go to LA. There probably won’t be public demands on that, but he has leverage. He is going to be a free agent (in 2019). He’s an LA guy and he can just let teams know he won’t re-sign next year with anyone but the Lakers.”

The Celtics and 76ers could also put a compelling package together for Leonard.

“I would say that’s the most likely thing,” another general manager told Sporting News. “He’s going to be their target any way you look at it, this summer or next summer. There’s not many other ways to explain what’s been going on with that situation other than him trying to get out of San Antonio.”

Kawhi Leonard's ongoing rehab in New York has created tension with the Spurs where his future with the franchise remains uncertain.

Leonard has reportedly been infrequently communicating with the Spurs.

Leonard has been going "weeks without responding to any of the club's calls and texts", according to a report from Ailene Voisin of the Sacramento Bee.

An updated version of Voisin's piece was changed to the following that eliminated that anecdote:

"He occasionally texts with some of his teammates, but according to Gasol leaves others in the dark."

While the San Antonio Spurs figure to receive interest from rival teams who would like to trade for Kawhi Leonard, it remains to be seen whether they will entertain a move.

The Spurs can offer Leonard a supermax contract extension of $219 million over five years.

Leonard has remained away from the Spurs during the past few weeks as he rehabs in New York.

"One well-placed insider who has closely monitored this situation told me recently that the Spurs continue to give off signals behind the scenes that they won't trade Leonard," wrote Marc Stein. "I'm sure they want Leonard to believe that, but this saga has reached the point that a trade has to be considered no less likely than the prospect of a Pop/Kawhi summit that leads to a detente."

Isiah Thomas played a pivotal role in the New York Knicks' trade for Carmelo Anthony in 2011, according to a new book by Ian Thomsen.

The Knicks and Nets were bidding for Anthony but Donnie Walsh's reluctance to include Timofey Mozgov was holding back a deal from getting done.

"Thomas and I had been sharing information for years, he had provided me with insight on the new generation of AAU players who were seizing control of the NBA, and I believed he would be interested in hearing about Anthony," wrote Thomsen. "But Thomas was gunshy. It had been three years since his departure from the Knicks and he was still being criticized in New York as if he had never left. He said he didn't know (former Nuggets exec Masai) Ujiri, and the last thing he needed was to have it leaked that he was involved in the talks for Anthony. He made it clear that he no longer had authority within the Knicks organization, which meant he had everything to lose and nothing to gain. Thomas could see how this would play out: The trade with the Knicks would collapse, word would get out of his involvement and he would be the scapegoat. 'I don't want anything to do with it,' he said.

“I explained why I had assumed that he would be interested in hearing about the negotiations. Anthony had stuck out his neck to force a trade to New York, and if the trade was doomed to fall apart because the Knicks weren't willing to include a back-end player like Mozgov, then it wouldn't only be Anthony who would be furious. Anthony's fellow NBA stars — his close friends — would be angry with the Knicks too, and it would become more difficult than ever for the Knicks to recruit another star in years to come. The future of the Knicks mattered not at all to me, but I figured it would be important to Thomas. He said he agreed with my point of view, as I knew he would, since he had helped me to understand this dynamic over several years of conversations.

“Thomas thanked me for the call and then insisted that he was going to keep out of it. His goal was to get on with his own life. If the Knicks were going to make the trade, then let them figure it out."

Thomas, however, did not stay out of it despite coaching at Florida International at the time.

"My phone buzzed with the call from Isiah Thomas. 'Well, I passed on the information,’ he said, without saying to whom it had been passed. 'Now we'll see what happens.' The next morning, the news broke that Timofey Mozgov had been included in the Knicks' offer to Denver. That night the trade was completed."

The Dallas Mavericks could have as much as $30 million in cap space this offseason.

"We have the cap room," Mark Cuban said. "That's why we have it -- to use it. There's no reason to save it.

"We would even use it before the draft. If we got a great player before the draft and we still have cap room now, going into the draft there might be something that we like. If somebody wants to get off money or somebody cuts somebody and we like him, we could sign them now."

Julius Randle, Aaron Gordon and Clint Capela are expected to receive attention from the Mavericks in restricted free agency.

Derrick Favors, Will Barton and Avery Bradley are three unrestricted free agents who could be targets.

Cuban doesn't expect much turnover of the roster this season.

"I expect us to keep a lot of our team together, at least 10 guys if not more," the owner said. "We need to clear a spot for the first-round pick, maybe the second-round pick and a free agent or two."

While LeBron James will be a free agent this offseason, the most interesting story could be the future of Kawhi Leonard.

The San Antonio Spurs could entertain trading Leonard this offseason if they don't sign him to a five-year supermax.

"What happens to Kawhi Leonard, is a link to what happens to LeBron," said Brian Windhorst on ESPN's SportsNation.

"Where Kawhi ends up this season, will have a direct impact on where LeBron ends up even if they don't play together. They will be linked in where their futures will be."

Windhorst added that the Lakers could approach the Spurs on a trade offer for Leonard. Windhorst also mentioned that James has the ability to complete an opt-in-and-trade similar to what Chris Paul did with the Clippers to get to the Rockets.
