North Carolina coach Roy Williams says he should have kept quiet last week, when he ripped fans who called his radio show to criticize the show.

On this week's radio show, Williams said he regretted having done that.

"I wish I had not said one word," he said Monday, according to a transcript of the show posted by the website insidecarolina.com.

In the news conference last week, a frustrated Williams said he was sick of the armchair criticism of his team.

"Everybody was talking about how they were Carolina fans for nine million years and how bad we are. I don't give a damn how long you're a Carolina fan, those are kids in the locker room, and they played their buns off tonight," he said last week. "Don't call me next week and say how good we are; keep your damn phone calls to yourself."
