So it wasn't much of a surprise when Saturday's game between the rivals at Koskinen Stadium came down to the final seconds.
In the teams' last three meetings the game has been decided by a margin of one point and this game followed suit.
With just 14 seconds remaining in the game, Lauren Gallagher scored to beat No. 8 UNC 9-8.
UNC (3-3, 0-2 in the ACC) started strong and made a statement at the whistle when midfielder Stone won the draw control and ran straight to the goal to score seven seconds into the match. Junior attacker Kellie Thompson added another Tar Heel goal just 1:59 later.
But for the next 24:09 UNC was silent offensively, while No. 4 Duke scored the next six goals. Blue Devil midfielder Kelly Dirks started the scoring barrage when Gallagher found her open in front of the Tar Heels' net just 22 seconds after Thompson's goal.
The Tar Heels' deficit didn't come from a lack of shots, though. UNC equalled Duke's 10 shots on goal in the first half.
"We didn't take advantage of the shots we had," junior defender Porter Wilkinson said. "There were a lot of shots that should have been goals."
The Tar Heels' offense came back to life when junior midfielder Christine McPike spun around three Duke defenders to score her first of four goals with 3:45 left in the half.
"We realized the goalie was good high and we needed to shoot low," McPike said. "We made that adjustment later, but it probably should have happened sooner."
