The Nets and Hawks are discussing a trade centered around Joe Johnson, according to sources.

Brooklyn would pair Johnson with a re-signed Deron Williams.

With no deal is close to completion, sources say the teams are discussing trade on multiple fronts.

Trading for Johnson would likely eliminate the Nets from their pursuit of Howard.

For Atlanta, trading Johnson would effectively be a salary dump of his $90 million over the next four years.

The Nets would have to piece together several contracts, including those of 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 for Johnson’s contract.
