During his stay, Barnes, who was joined by his head football coach Tom Knotts, was extended his second scholarship offer.
"Yeah, they offered me [Thursday]," said Barnes. "They said at the Shrine Bowl practice I did real well and at the Athens [Combine] they loved the way I compete.
"[The offer] puts them further up my list now that I know they are interested enough to offer me."
Currently, Barnes lists the Tar Heels along with South Carolina – his other offering school – as his co-leaders.
"They are tied," said Barnes. "I want to make a visit to South Carolina when all the coaches and players are there before I name a leader. When I was at South Carolina before, they only had one coach there and no players."
Barnes is hoping to make a verbal commitment by the end of June.
Working in the Tar Heels' favor is the enrollment this month of Barnes' mentor, Hakeem Nicks.
"Me and Hakeem [Nicks] are close and he is going to be up there," said Barnes. "He's going up there in two weeks."
During his junior season at Independence, Barnes caught 30 passes for 300 yards despite playing behind two senior wide receivers including Nicks. The 6-foot-4, 195-pounder will be the feature wide receiver in one of the premier high school passing offenses in the nation this coming season.
