SAN ANTONIO — As the start of free agency approaches, reports indicate that teams are ramping up their trade offers to the Spurs for Kawhi Leonard in an attempt to lure LeBron James to their city.

Now, ESPN's Adrian Wojnarowski is reporting that the Spurs are "fully engaged" in trade talks with some of those teams.

According to Wojnarowski, the Lakers and Celtics are two of the "several teams" the Spurs are discussing a trade with. Woj also reports that the Spurs would prefer a trade with Boston because the Celtics have "assets that the Spurs most covet in a potential Leonard trade."

Wojnarowski followed up on his "fully engaged" tweet with a caveat: the onus is not on the Spurs to trade Leonard but on other teams such as the Lakers, who feel "the urgency to get a deal done."

Wednesday, ESPN reported that the Lakers and Spurs had re-engaged in trade talks. The only previous talks reported between the Spurs and Lakers were short and unproductive, as it was described that the Spurs “slammed the door” on the Lakers when they came knocking, asking about Kawhi deals.

The NBA free agency period commences at midnight EST on July 1.
