Dwight Howard previously wanted a trade from the Orlando Magic to either the Brooklyn Nets, Los Angeles Lakers or Dallas Mavericks.
The Houston Rockets were involved in trade talks, but Howard appeared unwilling to commit long-term to the franchise.
But sources say Howard is aware that the Rockets have emerged as a more attract destination due to their acquisition of James Harden.
Howard reportedly does not want to play in his hometown of Atlanta, and the Mavericks have been trending in the wrong direction from a few months ago.
The Rockets will also pursue Andrew Bynum if Howard is unavailable.
