Ten schools have offered Duncan, a 5-foot-10, 199-pound running back from Charlotte (N.C.) Mallard Creek, including Duke, East Carolina, Pittsburgh, and Purdue.
Early on, Duke emerged as Duncan's leader but with his recruiting stock on the rise he has backed off those feelings.
"I still like Duke, but I want to see other schools," Duncan said.
With that said, Duncan has scheduled official visits to Pittsburgh for this coming weekend and Purdue for the weekend of Oct. 8.
If UNC decides to offer, Duncan says he'll likely include Chapel Hill within his official visit schedule.
"Coach Withers has done a great job since Coach Davis has left," Duncan said. "I'm very interested in UNC."
Although running back was his primary position prior to high school, Duncan was moved to slot receiver as a freshmen at Mallard Creek and led the team in receiving as a sophomore. He was moved back to running back for his junior season and rushed for 1,208 yards and 15 touchdowns on 95 carries (12.7-yard average). He has continued his impressive play this season rushing for 731 yards and three touchdowns on 73 carries, in four games.
Duncan's brief conversation with Withers took place during pregame warm-ups of UNC's ACC-opening win against Virginia.
"I love it," Duncan said of UNC's 28-17 victory. "I loved the atmosphere up there. The fans were great."
Following the game, Duncan spent time with former teammate and current Tar Heel freshmen Marquise Williams.
"He's said it's been a good experience and it's a learning experience to get out on the field," Duncan said.
