"The Grizzlies are again discussing whether to deal reserve guard O.J. Mayo.

This time, Memphis has explored at least two trade scenarios with the New Jersey Nets over the past couple of weeks, according to two NBA sources.

Yahoo Sports first reported the talks.

The Nets are interested in acquiring Mayo for salary-cap reasons as they try to clear room to make a run at Orlando center Dwight Howard in the offseason. With that in mind, the Nets have offered fourth-year guard Anthony Morrow for Mayo.

Morrow, a 6-5 shooting guard, will earn $4 million this year and is guaranteed for $4 million next season. Mayo is making $5.6 this season — the final year of his rookie contract. He has a $7.4 million qualifying offer for the 2012-13 campaign.

The Griz have not discussed a contract extension with Mayo nor do they plan to before the Jan. 25 deadline."
