I do think Roy gets unfairly criticized by a lot of Duke fans, and obviously the same can be said for the way UNC fans go about their critiques of K. But that's part of the rivalry. If a player is really, really good or has those sought-after intangibles....they're stock is going to be high. Cam Reddish, for example, left a lot to be desired at times....but it doesn't take a genius to see his potential. Same with Nassir Little. Both are long and athletic with ever-expanding perimeter games. Genetically, they look like NBA players right now. Doesn't mean they play like them.
For Coby, like Justise Winslow before him, they're seen coming in as guys who have a lot of specialties but maybe fly under the radar of NBA talent evaluators. Then, something clicks. Coby was known as a guy with a knack for scoring, but the question with him was how would it translate right away to the college game. Obviously, he exploded and so did his perceived value. For Justise, it wasn't necessarily his scoring, but a lot of the other things. Both guys went from fringe first-round picks to lottery guys in months.
Theo Pinson, for example, was seen as a guy who did a lot of things well, but nothing great out of high school. His game took four years to expand and it could result in a long professional career. His intangibles alone could keep him on an NBA roster into his 30s.
