LAHAINA, Hawaii — Before his team’s game against Butler here on Tuesday night in the Maui Invitational, Roy Williams went over his talking points, as he usually does, and he specifically instructed the Tar Heels to play hard and play with intelligence. Williams expected Butler to do both.

What he didn’t expect was his team to do neither for long stretches during its 82-71 defeat – one that left Williams so agitated he briefly snapped at a tournament public relations staffer who attempted to fix his microphone during his postgame press conference. Williams apologized for that, but not for the anger and disappointment he directed toward his team, and his own coaching.

“On game nights,” Williams said, “you’ve got to freaking step up and be a man on game night.”
