The Celtics and Clippers are talking again, but it would appear that getting a deal done would require the latter moving off its position. According to league sources, the Celtics are refusing to move off their last request for two first-round draft picks and DeAndre Jordan in exchange for coach Doc Rivers and forward Kevin Garnett. The moves are separate, with the Celts allowing Rivers out of the remaining three years of his contract and allowing him to sign with Los Angeles in exchange for the picks, and Garnett being sent west for Jordan. But they are intertwined in that the C’s would not deal Garnett for Jordan straight up. In light of that, there are parties with a vested interest who doubt a deal will get done. The Clippers broke off the talks earlier this week, saying they would go only as far as one pick and Jordan. But the fact they were the ones who came back to the table yesterday would seem to put the Celtics in a better position. The C’s, said one source, are holding the line. The possibility of altering the deal in a way that still meets the Celtics’ desire to jump-start their rebuilding process remains, but it seems fairly clear at this point that Danny Ainge wants longer term assets in any exchange. The impetus for resumption of talks is Chris Paul, one person close to the situation told the Herald today. The Clippers point guard can leave the club as a free agent, and keeping him is the team’s main priority. Some of those involved inferred from the Clippers’ halting of negotiations for Rivers that Paul had told the club he would have no problem playing for one of the other candidates the team has been interviewing (Byron Scott and Brian Shaw among them). But the All-Star has apparently injected himself into this conversation. “I think Chris would be OK with another coach, but he has to be excited if all of a sudden he gets to play for Doc Rivers on a team with Kevin Garnett, and all he’s losing is DeAndre Jordan,” said one source. “Chris Paul was always the ‘X’ factor in this. If the Clippers can do something that guarantees he stays with them, then they have to do whatever they can to try to make that happen.”
