Douglas says there's a "good chance" UNC would receive an official visit from Darby, the No. 1 ranked cornerback in the nation.
"They're one of his top five [schools]," Douglas said. "He likes North Carolina. He likes the program, he likes the location, the school itself, and everything about North Carolina. It's not too far from home, too."
Although he didn't participate in camp, Darby was among a large group of D.C. area prospects who visited UNC during the Tar Heels' first two-day camp.
"[The visit] went well," Douglas said. "[Darby] has a relationship with Coach [Marcus] Berry, Coach [Butch] Davis, Coach [Everett] Withers, and Coach Troy Douglas – but mainly Coach Withers and Coach Berry, who used to coach our rival school. He likes Coach Davis a lot."
Douglas, who accompanied the group of D.C. area recruits to UNC, says Darby's visit included touring the campus, spending time with 2012 prospects and current Tar Heel players, and conversing with UNC coaches.
"Mainly, [the UNC coaches] are trying to sell UNC [and] how good of a situation it would be for him," Douglas said. "They are still going to try to recruit him, even though he has verbaled to Notre Dame.
"They want him to come back down for a game. I don't know if he's going to be able to do that, because of our football schedule – we play a lot of games on Saturday."
Currently, Darby's focus is his track career.
"He just finished [a track meet] in Greensboro this past weekend," Douglas said. "He's going to be down in South Carolina this weekend to qualify for the U.S. International Junior Track Team."
Once that's completed, Darby will compete in the ESPN Gridiron Kings Seven-on-Seven Tournament.
Darby verbally committed to Notre Dame during a visit to the school in mid-April.
