"The New Jersey Nets are working feverishly to acquire All-Star Carmelo Anthony and are in the construction stage of a complicated, multi-team trade, league sources told Yahoo! Sports.

Nothing is imminent in the next 24 hours, but Denver and New Jersey are having ongoing discussions centered on No. 3 overall pick Derrick Favors and future first-round picks going back to the Nuggets. The proposed trade also would involve the Utah Jazz and Charlotte Bobcats. Under the proposal, league sources said the Nets would also send point guard Devin Harris to the Bobcats, who would move forward Boris Diaw to the Jazz, who send forward Andrei Kirilenko to the Nuggets to complete what one front-office source described as a "very complicated" deal.

One league executive said the Nets believe they're "getting there" on a trade for Anthony.

The Nets want to get a deal done before Anthony reports to training camp in Denver next week because league officials think the Nuggets will start working to convince him to stay.

Anthony still has heart set on the New York Knicks, but a case is being made to him the Nets are a compromise he'll have to accept to get his $65 million extension and get into the metropolitan N.Y. market. The Nets won't agree to a deal for Anthony without an extension agreed upon.

Anthony also prefers a trade to the Chicago Bulls, but Denver refuses to do a deal with the Bulls that doesn't include center Joakim Noah, and so far Bulls officials have refused to put him into any deal.

Anthony has refused to sign a three-year, $65 million extension with the Nuggets and has made it clear to team officials he's not comfortable with the franchise's stability. There's unrest within the organization, where George Karl's top assistant, Tim Grgurich, has left, league sources said. Grgurich has told friends he's angry about the franchise's refusal to retain former general manager Mark Warkentien. Karl is now without his two most trusted confidants in the organization, Warkentien and Grgurich."
