The Nets and Hawks are in advanced talks on a trade proposal that would send Joe Johnson to the Nets, one of a series of moves the teams are involved in Saturday as the midnight deadline approached.

"Brooklyn and Atlanta are engaged in talks on a possible Joe Johnson trade, sources tell Y! Nets plan would be to pair with Deron Williams," Woj tweets. "Both Hawks and Nets are engaged in talks on several fronts. No deal close on Johnson, but sides have gone back and forth on possibility."

Later, Woj noted that the Nets had been in "aggressive talks" for Luis Scola and reported that If the Nets don't do a deal for Johnson, they're considering a "significant offer" for O.J. Mayo.

In addition to Nets, the Celtics, Pacers and Suns are in the mix for unrestricted free agent O.J. Mayo, league source told Ken Berger.

The decision by Jordan Farmar to opt-in earlier Saturday may be part of the planning for the trade. In a later report on Yahoo!, Woj writes, "Jordan Farmar, who opted into the final $4.2 million year of his deal on Saturday, Anthony Morrow, Johan Petro and a sign-and-trade with one of the Nets free agents' to make the exchange of salaries work."

Michael Cunningham of the Atlanta Journal Constitution confirms the talks. "Hawks source says Joe Johnson trade is one of several trade possibilities being discussed. None close to fruition for now."

Johnson is owed nearly $90 million over four years. Atlanta's new GM, Danny Ferry and Billy King were teammates at Duke and remain close friends.
