The Nets are close to acquiring multiple first round picks that will be used in a potential trade for Carmelo Anthony, two people familiar with the situation told CBSSports.com.

New Jersey has agreed in principle to a three-team trade where the Nets receive a first round pick in 2012 from the Rockets that will be lottery protected according to the Houston Chronicle and an additional first round pick from the Lakers in 2011.

Houston would acquire Terrence Williams, while Joe Smith would be sent to the Lakers and Sasha Vujacic would go to the Nets.

The deal can't be finalized until Wednesday when Smith becomes trade-eligible.

New Jersey already owns Golden State's 2011 lottery protected first rounder, which would also be included in a trade for Anthony along with the two picks acquired in this trade and one of their own over the next two seasons.

Derrick Favors and Troy Murphy would also be included in any trade the Nets may complete for Anthony.

The Nets have received assurances from several people from Anthony's camp that he would sign an extension with the club.

The framework of the three-team trade came together on Tuesday, just two days after word leaked that Anthony would only sign an extension with New York.

According to a Yahoo! report, the Nets are confident owner Mikhail Prokhorov and Avery Johnson can convince Anthony to commit to the Nets in the long-term.
