East Carolina is the only Division I-A school to offer Frederick, a 5-foot-8, 188-pound tailback from Benson (N.C.) West Johnston. However, he's fielding interest from schools throughout the region.
In addition to UNC, Frederick has camped at East Carolina and NC State, and will camp at Virginia Tech Saturday.
Following a spring visit to UNC, Frederick favored the Tar Heels. However, his summer experiences have confused his thoughts.
"I'm not sure how I feel, because everybody is starting to get interested and it's getting puzzling," Frederick said. "I don't know what I want to do, yet."
Frederick hopes to have a better grip on his recruitment by August 1.
"A lot depends on if I get any more offers, who offers, and how I feel at that time," Frederick said.
While at UNC's camp, Frederick worked out at all four sessions under Ken Browning, UNC's running backs coach and Frederick's primary recruiter.
"He taught me a whole bunch of different drills I can work on to get my hip flexors better so I can get my [40-yard dash] time down," Frederick said. "He taught me a lot of stuff that I can see already has really helped out."
While at the camp, Frederick ran a 4.61-second 40-yard dash. However, Browning feels that time could be much lower if Frederick, who also excels at baseball but has never run track, fine-tuned his running technique.
"He said I'm nowhere close to where I could be," Frederick said.
During one-on-one passing drills, Frederick made the biggest impression. His performance even drew praise from Butch Davis, who pulled him aside.
"[Davis] was telling me that my routes looked really good and I had really good hands," Frederick said.
In addition to the camp activities, Frederick's stay included a campus tour and a film session.
"Everything went wonderful," Frederick said. "I had a really good time."
