Tuttle, a 6-foot-2, 314-pound defensive tackle from Lexington (N.C.) North Davidson, says he doesn't have a leader among the trio and has no timetable for a verbal commitment.
With UNC in particular, assistant coach Chris Kapilovic is recruiting Tuttle. The two speak every other week.
"He's just catching up with how I'm doing," Tuttle said. "He asks me how my summer is doing. He's funny. I enjoy talking to him."
Over the summer, Tuttle camped at the three aforementioned schools plus NC State. With UNC in particular, Tuttle attended Fedora's Freak Show.
"The UNC camp was different than the others," Tuttle said. "They tried to make it fun. It was cool. It was fun."
Fedora's Freak Show provided Tuttle with his first opportunity to work out under Keith Gilmore's tutelage. Gilmore, of course, coaches UNC's defensive linemen.
"He's pretty cool," Tuttle said. "I learned a lot."
Tuttle plans to attend several college football games this fall, primarily to the aforementioned three schools. He's approaching his schedule on a week-to-week basis and lacks any definite plans. For the first week, he's working out the details to be in Columbia for the match-up between UNC and South Carolina.
