While Doc Rivers still continues to ponder whether he wants to coach the Celtics or Clippers, the two teams reignited talks regarding the longtime coach and Kevin Garnett in a complicated deal that would include Los Angeles center DeAndre Jordan.

That's what is known right now. The rest is still being discussed and both sides are reaching frustration, according to NBA sources. While the Celtics demanded Clippers point guard Eric Bledsoe in any deal, they have backed off that insistence and instead want the Clippers to take on the contracts of Courtney Lee or Jason Terry and preferably both.

If the Celtics plan to part with Rivers, they want a young piece, draft picks and salary cap relief. Realizing that signing Terry and Lee to multiyear deals at the mid-level exception (5-plus million) was a mistake, the Celtics would prefer the Clippers accept those deals to facilitate clearance to negotiate a contract with Rivers.

Meanwhile, a source close to Rivers told the Globe that Rivers is still grappling with the decision, especially as the trade gets more complicated and negotiations more contentious. The talk of the Clippers acquiring Paul Pierce in the trade are remote, especially since the Celtics would have to honor his deal and send him to the Clippers with a $15 million salary.

And don't expect the Celtics to waive Pierce just to see him sign with the Clippers during free agency.
