You and I seem to have different opinions of Rondo, then. Personally, I think he's an overrated, ball-dominant stat padder, but that's just my two cents.
I have a suspicion that Rondo is a really, really difficult person to get along with. I haven't read anything that specifically said that, although I know that he and Ray Allen apparently had some issues. Having said that, here's a blurb from Bill Simmons on the idea.
Of course, keep in mind that Simmons is a complete Celtics homer and has been using the Kings as suckers in hypothetical trades in his pieces for many years.

Look, I may or may not have been wasting inordinate amounts of time this summer on ESPN's Trade Machine making up fake Rondo trades. With Detroit out, one other Rondo suitor makes sense: the Kings. They're rebooting around a new arena, a new owner whom everyone loves (Vivek Ranadivé), a rejuvenated Boogie Cousins (at least that's the hope), and the chance to play an entire season without a Maloof involved. What about Rondo, Wallace's $30.3 million basketball cadaver and Jordan Crawford's expiring for Ben McLemore, the John Salmons–Patrick Patterson expirings, Greivis Vasquez, Jimmer Fredette and an unprotected no. 1 pick in 2014? (Thinking.) You're right, I need to get off the Trade Machine.

But at least Simmons is with me in the rondo kings match
