I don't know a lot about Nance, but it doesn't seem that he's the same level of shooter as Manek. Plus, as the other guy said, he's played mostly scrubs so far. And does he have the same knack for hitting big shots?
Neither is UNC though. Everything is relative. Kind of like how programs look against each other. KU, for example, is a great program and ranks ahead of almost every program. Unless you put it next to Kentucky or UNC, in which case they are looking up.
