Willis, a 6-foot-4, 255-pound defensive lineman from Duncan (S.C.) Byrnes, spent Thursday afternoon in Chapel Hill. He participated in the first session of UNC's two-day camp.
Most of Willis' UNC stay was spent hanging out with Blake.
"For the most part, we just talked about everyday stuff – how I'm doing," Willis said.
Along with Butch Davis, Willis and Blake watched film of previous players Blake has coached.
"He was just showing how he taught the things that [the former players] did," Willis said. "He showed me how he could develop me into a player like that.
"It's good to see, because I want somebody that's going to develop me and take me to the next level. By him showing me, there's proof."
Before leaving campus, Willis spoke to Davis one-on-one.
"He was just talking about how I'm doing, how the school is for me, how's life, he was talking about my mom that's recently deceased," Willis said. "But we were just talking everyday stuff – it wasn't that much about football… He was just saying that he wants me down there."
In "about a week," Willis says, he'll narrow his list of 25 scholarship offers to just five schools.
"I have a good idea [of who's on the list], I'm trying to finalize it," Willis said.
UNC's chances of making the cut are good.
"[UNC's odds] are high," Willis said. "They'll be on there. Coach Blake, Coach Butch Davis, and the rest of the coaching staff make the difference."
Before narrowing his list, Willis, who has visited just about every east coast school that has offered him, hopes to visit California and UCLA.
"[Corey Miller] and I are trying to get to the west coast together – trying to find some tickets," Willis said.
Willis will take official visits to each of his five finalists during the season.
With the plan to be a January enrollee, Willis expects to make a verbal commitment right after his senior football season.
"First [the most important factor is] education," Willis said. "I want to be an engineer so the school has to offer that.
"And then [I'll focus on] the facilities, coaches, the atmosphere around the school – things like that."
