It is kind of funny if Shaq really does want Rasheed back. Shaq is going to have a hard enough time getting the minutes he wants even without Rasheed here. If Rasheed returns and Perk makes it back, it's possible Shaq isn't even in the rotation.
If I was Shaq, I'd keep my mouth shut.
Still, if he comes back, we could look into trading Baby. Though I don't love the idea, he's really our only trade asset to land a lengthy 3.
