I don't think they have to cater to the UNC crowd. All they have to do is put a team on the court that plays hard and wins. If the team is winning, the players will endear themselves to the fans no matter where they are from.
Focusing on UNC players has the double-edged sword effect of making our team look like they're catering exclusively to the Tarheal massive, while ignoring the legitimate needs of a winning team. Obviously, if a great player could help us win and he had NC connections, that would be helpful. But, talent comes far before local connection.
