Costner helped the 10th-seeded Wolfpack (16-14) accomplish that Thursday night, scoring a career-high 30 points and grabbing seven rebounds to help end No. 21 Duke’s reign as tourney champions 85-80 in overtime in Tampa, Fla. “As you all know, the rivalries are great on Tobacco Road, and nothing will make our fans and us happier than to beat Carolina and Duke,” Costner said. “To succeed in beating them this year is a great accomplishment.” Freshman Brandon Costner already knows what makes a disappointing season bearable at North Carolina State. Try beating North Carolina during the regular season, then knocking off Duke in the Atlantic Coast Conference tournament.
