North Carolina basketball coach Roy Williams said Friday the incident during last Saturday's 103-64 win over Presbyterian College that led to a fan being ejected has gotten too much attention."I wish it hadn't happened," Williams told reporters, reiterating what he had said earlier in the week on his weekly radio show.The incident got national attention, with video of the exchange circulating on the Internet.Williams stopped coaching during last week's game to point out a heckler to security guards, and the man, a Presbyterian fan, was removed from the Smith Center.The fan, Brian King of Concord, had shouted at UNC's Deon Thompson to miss a free throw.Williams said he thought the fan was a Carolina fan until he was informed otherwise Monday."I swear to goodness," Williams said.Then he recounted all the tough talk his team had to endure at Madison Square Garden against Ohio State and Syracuse, where some players' parents were upset and one parent got into a heated exchange with a fan."We have to live with that on the road," Williams said.
