Z-Bo is entering free agency after 8 seasons with the Grizzlies and everyone wants to know what his next move is gonna be.

With "super teams" being the hot topic, we asked Randolph if he would consider pulling a Durant and joining a loaded squad like Golden State or Cleveland.

"Memphis," Randolph replied ... "We're gonna build a super team there!"

With Blake Griffin, Chris Paul and Gordon Hayward available, it's not completely out of the question ... though even Zach seems to acknowledge it's unlikely they'll end up in the BBQ capital of the world.

We also talked about his teammate, Vince Carter, who's 40 years old -- and Randolph told us he thinks Vinsanity can ball in the NBA for at least another 4 years!!!

Zach says they don't call him "Half man, half amazing" for nothing.
