I don't get the impression that he's going to pull the trigger to anyone in the near future, though that is an opinion and could obviously be wrong. I don't see any reason for him to rush, he's got a great offer list, Tennessee and others will certainly wait on him, and I would guess there's probably some interest on his part to see how serious UNC and/or Duke get.
Not saying I think he will roll over and commit to either spot if they were to offer, but IMO if you're a smart kid, you're crazy not to at least listen when those programs are showing interest.
I think Tennessee is in good shape there early on. His family are Tennessee fans from way before he was a big-time prospect, so that's a plus, and from what I can gather there's a really good relationship in place with Coach Martin. I wouldn't get discouraged if something doesn't happen early, I think the Vols will be deep in this one.
