Atlantic Notes: Humphries, Celtics, Rondo, Knicks

It appears his marriage to Kim Kardashian wasn't the only recent relationship that ended prematurely for Kris Humphries. Darren Heitner at Sports Agent Blog writes that, less than a year after firing agent Dan Fegan in favor of Pinnacle Managment's Marc Cornstein, the Nets forward has parted ways with Cornstein and returned to Fegan. The Lagardere Unlimited representative will be tasked with negotiating a new contract for Humphries when he hits unrestricted free agency this summer.

Here are a few more Tuesday updates out of the Atlantic division….

• "[Celtics GM] Danny [Ainge] is always going to look for trades," Doc Rivers tells A. Sherrod Blakely of CSNNE.com. "You know who Danny is. But having said that, I don't think Danny is going to do anything crazy."
• The Celtics' coach also tells Blakely that he would prefer to let his injured players get healthy rather than shake up the roster at this point.
• Gerry Callahan of the Boston Herald wonders if now may be the best time for the Celtics to trade Rajon Rondo.
• The Knicks had interest in recent Cavs signee Manny Harris and may have been considering signing him to replace Jeremy Lin before Lin broke out, tweets Jason Lloyd of the Akron Beacon Journal.
• Though he appears to be healthy, the Knicks' Baron Davis isn't a threat to take too much of Lin's playing time away, says Tim Bontemps of the New York Post.
