Zach Randolph has stressed that he's very happy in Memphis and would prefer to stay put.
Problem is, it's not really his call.

He's set to be a free agent if he opts out of his current contract, which seems likely given his age (32) and the fact he'd probably prefer a longer term deal to wrap up his career. Which means the Grizzlies, who are limping along largely due to injuries, may have to do the prudent thing and move Randolph now to try and sell high on his current trade value.

And the Grizzlies have started making some calls on it, according to Jared Zwerling of Bleacher Report:

Several sources said the Grizzlies are currently shopping power forward Zach Randolph, and two of them are hearing there's a destination and main trade piece involved: New Orleans and stretch-4 Ryan Anderson, who's averaging a team-high 21.7 points per game on 47.7 percent shooting from three-point range.

“A trade centered around Randolph and Anderson should happen down the line this season,” one source said.

The Grizzlies aren't in the kind of position where a total rebuild would be necessary as they have both Marc Gasol and Mike Conley in place for the long-term. But it's either pay up on Randolph again, or change direction some and try and acquire some value back in exchange for him.
