Chaffin's persistence paid off in the form of plenty of individual attention.
"It was great, because for a while I was literally the only recruit there," Chaffin said. "So I got to spend a lot of one-on-one time with Coach [Larry] Fedora. He's a really great guy."
In return, UNC improved its chances with Chaffin.
"They really impressed me with the way that the coaches were able to adapt – obviously that's a really good quality," Chaffin said. "I was the only guy there, but the way they were able to make me feel by the way they all devoted their time was impressive. They could have just said ‘You're the only recruit here, so it's not worth our time to sit here and get snowed in.' But they were fired up and brought a lot of energy, which I thought was great. They really made me feel like I was important to them, which is obviously a big deal."
Despite the positive remarks, Chaffin has refrained from naming favorite schools. Following the Spring Evaluation Period, he plans to narrow his focus to two or three schools and verbally commit in early June.
Christian has developed quite the pipeline into the FBS ranks. As a result, Chaffin has several former teammates at various schools, including Des Lawrence at UNC.
"I've been really blessed, because it really gives me the inside scoop on three of the four in-state programs," Chaffin said. "Wake [Forest] is the only one that I don't have a direct teammate at. But it gives me the opportunity to spend the night with guys and see how I'd fit into the locker room."
Charlotte, Duke, Mississippi State, Northwestern, UNC, NC State, Virginia Tech, and Wake Forest have all offered Chaffin a scholarship.
In addition to eating dinner with Fedora, Chaffin met with UNC's strength and conditioning and academic support staffs, toured the campus, and had a meeting with Seth Littrell, the Tar Heels' newly hired assistant head coach for offense.
"They really were welcoming," Chaffin said. "They were having to adjust. I appreciated the way they adjusted because of all the crazy stuff going on. But I really had a great time. They impressed me."
Chaffin also watched film with Chris Kapilovic, UNC's offensive line coach.
"We just went through drill tapes to see what they do and see how I fit." Chaffin said. "He was telling me how'd I'd fit into the offense."
UNC projects Chaffin as a center, the position he has been playing for Christian.
"They told me that they really liked my film and they loved my athleticism," Chaffin said. "They want me to pull, get around. They said I'm pretty athletic on tape. They said I'm nasty on tape - they liked the way I get out there and hit a linebacker. They really like the way I can get out in space and block on the next level."
Chaffin, who previously visited UNC for a junior day a year ago, plans to return to Chapel Hill for the UNC-Duke basketball game's makeup date on Feb. 20. He's also scheduled to visit Duke on Saturday and Wake Forest on March 1.
Besides UNC, Chaffin has visited Northwestern and NC State.
