"Walk off like we came here to win," Collins said.
The reminder, which came with 1:15 left in the game, was one that many didn't expect No. 2 Duke to need in its matchup against fourth-ranked North Carolina.
That's because the Blue Devils entered the game as an underdog.
"At Duke, you're not put in that position. Pretty much not ever," Duke forward Shane Battier said.
Duke coach Mike Krzyzewski added, "I would think probably more people thought we would lose here today than win."
But Duke, coming off a loss to Maryland and playing without center Carlos Boozer, remained confident. The Blue Devils played what they call Duke basketball -- 40 minutes of running and gunning and trapping.
And in the end, Duke left the Smith Center with a 95-81 victory. It avenged its Feb. 1 loss to North Carolina, proved it could still win without Boozer and won a share of its fifth consecutive ACC regular season title.
"We knew we could win," Duke guard Chris Duhon said. "That's why we kept our championship look. That's why you didn't see us celebrating after the game."
It's that confidence Duhon spoke of that helped the Blue Devils never look back from a two-point halftime advantage. It's that confidence that allowed them to push their lead to as many as 19 points.
