The Nets are sending rookie Derrick Favors and point guard Devin Harris to the Jazz as part of the package in a deal that also includes the Golden State Warriors.
The person spoke to The Associated Press on condition of anonymity because the deal hasn't been announced. It was first reported by The Record of Bergen County, N.J.
Harris, a former All-Star point guard, and Favors, the No. 3 pick in the draft, were part of the package the Nets were offering the Nuggets all season for Anthony. While they couldn't get Denver's All-Star forward, Wednesday's trade stole some of the spotlight from the rival Knicks on the night Anthony arrives at Madison Square Garden.
The Jazz were a perennial contender with Williams, but his reputation took a hit in Utah when Hall of Fame coach Jerry Sloan retired the day after a clash with him during a game.
Williams was expected to be one of the headliners of the 2012 free agent class along with 2008 Olympic teammates Dwight Howard and Chris Paul, and the small-market Jazz could have faced losing him for nothing.
The Nets now hope Williams will sign a contract extension with them, which they can offer this summer. If so, he would become the face of their franchise when they move into their new arena in Brooklyn for the 2012-13 season.
New Jersey has been desperate to make its first score under new Russian owner Mikhail Prokhorov. The Nets talked with LeBron James, Dwyane Wade and Chris Bosh last summer and when that failed they turned their attention to Anthony. They quickly bounced back from the disappointment of missing out on him with Williams, who is averaging 21.3 points and 9.7 assists.
