North Carolina never trailed Saturday during their 71-56 victory over Boston College in the semifinals of the Atlantic Coast Conference tournament. But Williams is never content when the Tar Heels are playing sloppily.
Even with a big lead.
"I hit it with my hand. The referee told me I couldn't do that. I said, â€˜I'm not mad at you. You know that,'" Williams said after North Carolina moved a step closer to its first ACC tournament title in nine years. "He said, â€˜But the perception.' I said, â€˜You don't referee on perception. There's 8,000 people at least that think you make a mistake on every call.'"
Williams said he was upset because of a miscommunication on the Tar Heels bench. One possession after taking a bad shot, the team nearly didn't get a shot off because coaches were screaming and a play call wasn't heard.
That's about all the Tar Heels did wrong.
Brandan Wright scored 20 points on 10-of-12 shooting - most of them dunks - and the conference regular-season co-champions weathered a Boston College spurt that trimmed a 20-point deficit to nine before pulling away again.
Wayne Ellington and Ty Lawson scored 10 each and Tyler Hansbrough grabbed 13 rebounds for the Tar Heels (27-6), who will face 10th-seeded North Carolina State in today's championship game.
"We haven't won an ACC championship, so we basically wanted to come out strong against BC and not have them be in the game," Lawson said. "Just get out strong and get ahead, so we don't have to fight back the whole game."
Sean Marshall led Boston College with 23 points. ACC Player of the Year Jared Dudley bounced back from a subpar first half to finish with 20. The fourth-seeded Eagles (20-11) trailed 48-28 before Marshall scored eight during a 13-2 run that trimmed BC's deficit to 50-41.
Reyshawn Terry made a long 3-pointer and Wright followed with a dunk as North Carolina regained control. The Tar Heels rebuilt the advantage to 18, and Boston College never got closer than 13 the rest of the way.
Boston College has lost five of its last seven.
North Carolina is back in the championship game for the first time since 2001. The Tar Heels haven't won the ACC tournament since 1998, and their current streak of eight consecutive years without a title is their longest since 1958-66 - the year before Dean Smith won his first ACC tourney.
North Carolina has not trailed in the tournament and held Boston College to 34.5 percent shooting.
