The two teams that have separated themselves from the rest of the pack, making the conference as top-heavy as Pamela Anderson?
But what happens when one of them proves that it might not belong in that esteemed company -- that, in fact, it might be an impostor?
For the second game this season against No. 5 Duke, North Carolina raised that exact question. Watching powerlessly as the game began to slip away yet again in the last few minutes of the first half, the Tar Heels imploded in a 90-75 loss Sunday in front of 7,842 at Carmichael Auditorium, providing further evidence that they aren't on the Blue Devils' level.
After the 19th-ranked Tar Heels led by as many as nine points in the first half, the Blue Devils ripped off a 40-8 marathon run that bridged halftime. In the midst of that spurt, UNC hit only one of its first 21 field goal attempts to open the second half.
With the win, Duke (23-3, 16-0 in the ACC) became only the second team in 25 years of ACC play to go undefeated in the conference.
"You can't go through slumps in scoring like that and beat a team like Duke," said UNC coach Sylvia Hatchell. "They're just too good."
Just as they did in a 102-82 win against the Tar Heels (22-7, 11-5) on Jan. 24, the Blue Devils began to pull away in the final four minutes of the first half Sunday.
Duke guard Alana Beard, who torched UNC for 26 points, hit a free throw that set the Blue Devils off on a 14-6 run during the final 3:26 of the opening half and gave them a 45-42 lead.
As UNC continually found iron at the start of the second half, Duke scored eight straight points.
