Rumors that three teams are vocal about trading into the 3 spot. Charlotte, Portland, and Memphis, with Hornets and Grizzlies the most aggressive.
One would think the target is Clingan, who might not even be there. Crazy that Donovan Clingan is the massive hinge for this draft. Not something I'd expect.
In the unlikely scenario that Clingan lasts past Houston, I suppose the Spurs could put that pick for sale and trade down. Right now it's hard to think Clingan will last past the first three picks, though, with Houston trading him.
If Houston trades down, they may still get Sheppard. Unlikely, so the play may even be to keep trading down. They don't really need anything from this draft.
