According to the Charlotte Observer (Above the Rim blog) ...
Duke and North Carolina fans may differ in their opinion of the selection of Karl Hess to referee his first NCAA championship game Monday night. Hess was the lead official on the crew that ejected Duke’s Gerald Henderson for the flagrant foul that broke North Carolina center Tyler Hansbrough’s nose March 4.
Whether you agree with that call or not, Hess is one of the ACC’s best officials and deserved his position in this game. Edward Corbett and Tony Greene, who both worked their third NCAA title game Monday night, also are excellent referees. - Ken Tysiac
