I think they'll be better than the first two for sure, and on par with UNC and Maryland. UNC will be a top 2 team, though I'd have more confidence in that if Tokoto hadn't declared, and if they didn't have the ban hanging over their heads.
Duke lost their 4 most important players, and while the guys they have coming in are good, they're not top 5 material right off the bat - especially because they have only one real ball handler (Thornton) who's not close to being the kind of floor general Jones was, and lacks consistent range beyond the arc. They do have some shooters and scorers on the wing, but their lack of rim protection is going to be killer - just like it was in 2013/14. I think they're a top 20ish team.
Kentucky, despite their recent recruiting misses, has a good, balanced team and a very good point guard in Ulis. But Lee and Willis haven't developed, Poythress is all athleticism and is coming off an ACL tear, and nobody can shoot. I also don't think Ulis and Briscoe will co-exist comfortably. They'll beat cupcakes, but struggle against good teams.
