Here we go again ...

Sources confirmed to ESPN on Wednesday that the Clippers and Celtics re-engaged in trade talks that would send Doc Rivers and Kevin Garnett westward. From colleagues Marc Stein and Ramon Shelburne:

Discussions between the Los Angeles Clippers and Boston Celtics on a deal that would send Kevin Garnett and coach Doc Rivers to Los Angeles resumed Wednesday, just one day after they were declared "off" by both sides, sources told ESPN.

One source close to the talks expressed optimism that a deal could be done as soon as Wednesday night, with the Clippers swapping DeAndre Jordan for Garnett and Boston receiving two first-round draft picks as compensation for Rivers.

As for Wednesday's meeting between Danny Ainge and Doc Rivers:

Boston Celtics coach Doc Rivers and president of basketball operations Danny Ainge met Wednesday evening with the hopes of settling the coach's future with the club, sources told ESPN.

Ainge always has made it clear to Rivers that the team's preference is for him to remain as coach, even after negotiations to allow him to leave for the Los Angeles Clippers broke down on Tuesday morning. However, sources with knowledge of Rivers' thinking say the coach remains unsure about remaining in Boston if the team is headed for a rebuilding process.

"He wants another championship or at least another chance at it," a source close to Rivers said. "He doesn't want to go through a rebuilding process."

Rivers' preference, sources said, is to coach next season. He also would have the option of returning to broadcasting if he did not want to continue with the Celtics and an exit to the Clippers could not be facilitated.

The Clippers, while proceeding with second interviews with Byron Scott and Brian Shaw on Tuesday and Wednesday, respectively, are keeping an eye on the situation, sources with knowledge of the situation said. If Rivers were to inform Ainge he did not want to coach in Boston next season, it would provide the impetus for talks between the teams to resume immediately.

* Rapid reaction: The Clippers -- after walking away from negotiations on Tuesday -- appear to have reached out to the Celtics to restart trade talks and the fact that Boston is listening tells you all you need to know about today's meeting between Rivers and Ainge. Rivers likely remains on the fence about the future direction of the Celtics and -- with the possibility of getting a deal done with Los Angeles back in play -- Ainge now has to re-investigate to see if he can get the assets he desires in order to allow Rivers his coaching freedom.
