Regardless, there's been no change in Clark's favorite schools list.
"I'm still open," Clark said. "I believe North Carolina is a great school still. It's one of my top schools. I have other visits coming up and I'll keep North Carolina in mind."
Clark will officially visit Michigan the weekend of Jan. 7, Akron the weekend of Jan. 14, and Penn State the weekend of Jan. 28. Michigan State may get his fifth and final official slot.
"I haven't decided if I'm going to take a fifth visit, yet," Clark said.
Of the aforementioned schools, Akron, Michigan, and UNC have offered Clark a scholarship, with the Wolverines' offer being the newest. Michigan offered last Wednesday.
Clark's UNC official visit gave him an in-depth look at the academic side of the school.
"They brought a lot of people in to talk about majors – like sports medicine and sports management, which interest me," Clark said.
Clark also spent a lot of time hanging out with current UNC players, including host Zach Brown.
"[Brown] and I have similar personalities," Clark said. "We just clicked. Everything he was up for, I was up for, basically."
Before heading to the airport on Sunday afternoon, Clark met individually with Butch Davis.
"He's a great guy – really great," Clark said. "He gave me a little background on him. He talked to me about the team. He's very wise and he gave me a couple pointers on a few things with the recruiting process."
Clark, who is being recruited as a linebacker by UNC, also met with linebacker coach Art Kaufman during his stay.
"We talked about everything," Clark said. "There wasn't anything we didn't talk about. He talked about how he coached and the program."
