If the San Antonio Spurs get serious about trading Kawhi Leonard, the Celtics, according to multiple league sources, would like to be involved. But there has been nothing yet to indicate they have a realistic chance.

A Western Conference source with an interest in the proceedings told the Herald the Spurs did have a brief discussion with the Celts today, but there was no real negotiation. It was the first contact between the teams since before the draft, but even those talks did not include the C’s making an offer. That brief call, according to two league sources, went nowhere.

San Antonio has been checking the marketplace to see what kind of return it could get on Leonard, but it’s hard to see things working out with the Celtics under the current circumstances of the All-Star forward’s health and future plans.

As noted in a recent Herald story, the Celts would need assurances that Leonard’s quadriceps injury is healed and that he would be willing to stay with the team beyond next year. Leonard can opt out of his contract and become an unrestricted free agent after the 2018-19 season. He played in just nine games this season because of the quad problem, and questions about whether he could and should have played more strained his relationship with the Spurs.

Therefore, logic says anything the Celtics would be willing to give up at this stage would have to be reflective of those issues. That likely wouldn’t be enough for the Spurs.

It’s not believed the Celts are willing to move either Jayson Tatum or Jaylen Brown, and whether they’d put the 2019 Sacramento first round pick (protected only if it’s No. 1 overall) on the table likely is dependent on the sides getting serious enough to allow the C’s permission to speak with Leonard, gauge his interest in Boston and check his medical information.

But everything we’ve heard at this stage is the process is miles away from any of that. And the best information circulating through league front offices is that Leonard is still intent on getting to the Lakers, either by trade now or as a free agent next summer.

The situation is beginning to resemble the Paul George affair from last summer. The Celtics felt they could have beaten the deal offered by Oklahoma City (even though the transaction worked out better for the Pacers, and ultimately for the C’s too).

This time with Leonard and the Spurs, they would like to have a chance to be in the discussions at the end, though it doesn’t appear (again, yet) as if there is much of an avenue for an agreement.
