"The Denver Nuggets and New Jersey Nets are advancing on another complicated multiteam trade proposal that would likely fit Carmelo Anthony's criteria for signing a contract extension with the Nets, league sources told Yahoo! Sports.

Anthony is inclined to accept a trade and contract extension with New Jersey over his preferred choice of New York only if the Nets are able to bring back a package of significant talent with him, league sources involved in the talks said on Monday.

So far, there are trade scenarios that include a combination of Anthony's Denver teammates – including forward Al Harrington – and other league players coming to the Nets.

"The way this is structured now, the Nets will significantly upgrade their team," said one NBA executive involved in the talks.

Said a Western Conference executive whose team has pursued Anthony: " 'Melo wants something similar to the Orlando deal, where he won't have to go into New Jersey – or anywhere he's going – without some help right away."

Denver's and New Jersey's trade partners are still unclear, but league executives said the Nets and Nuggets are tweaking several possible proposals with multiple teams. For now, New Jersey general manager Billy King is preparing to send rookie forward Derrick Favors, the expiring contract of Troy Murphy, two or three future first-round draft picks and $3 million to Denver for minimally Anthony and Harrington. More Nuggets and Nets would likely be on the move, too."
