For the first time in more than a month, a North Carolina high school football team had tasted victory, outlasting a conference rival on the road by a point in overtime.

But since the game last Friday, people haven’t been talking so much about the final score. They have been talking about an Instagram video posted the next night by an assistant coach, who used a racial slur to refer to the players on the team — many of whom are black — while he was out at a bar celebrating the win.

In the video, the coach, John Hoskins, shouts, “White power, Knightdale. I still love you,” using the epithet.

He later deleted the Instagram story, but it was too late — someone had already shared it with officials at the public school where he worked, Knightdale High School of Collaborative Design near Raleigh, N.C.
