North Carolina State juniors Brandon Costner and Trevor Ferguson won’t return to the Wolfpack next season, although they are following different paths away from Raleigh. Costner declared for the NBA Draft after averaging 13.6 points per game this past season. Meanwhile, Ferguson is quitting the team and will earn a degree in science, technology and society during the summer. After transferring from Pittsburgh in 2005, Ferguson averaged about four points per game for the Wolfpack.
