Ainge also denied a report that he is actively shopping Rondo, saying that the last time he tried to negotiate a deal with Rondo in it came this summer during the Chris Paul trade discussions.
"I anticipate him being here for a long time," the Celtics president said when asked about Rondo's immediate future. ...
"These rumors have never stopped, but I haven't made a call mentioning Rondo's name since last summer," said Ainge. "That was during all of the Chris Paul stuff.
"Now, this time of year you're going to get a lot of calls from other teams," he said. "But that's just normal. I don't anticipate anything happening."
ESPN.com reported Wednesday that the Celtics are fed up with Rondo's attitude and want to rebuild without him, but Ainge said Rondo's relationship with Doc Rivers has never been better.
"Rondo and Doc get along fine," said Ainge. "That doesn't mean there aren't bumps in the road. But I think Rondo and Doc are actually better now than they have ever been. But there are other issues that concern us a lot more than that. There's nothing new to this."
