The offer coupled with his official visit experience over the weekend, has Frierson on the verge of closing out his recruitment.
"I was looking at going to Ohio and Tennessee, but I don't think I'm going to take those visits," Frierson said. "I'm thinking about just leaving it down to [UNC and Illinois]."
If nothing changes, Frierson, who has also officially visited Illinois, plans to make a verbal commitment by the middle of this week.
"It's going to be a tough decision," Frierson said. "But it's a decision I'm going to have to make and live with it."
Frierson says he's not leaning in any one direction as he sees a lot of similarities in UNC and Illinois.
"The thing I like about UNC is that it's real cool, everybody is down to earth, everybody is outgoing," Frierson said. "All the coaches are cool, the players are also cool – I like that a lot.
"Illinois, it's like the same [as UNC] – except the weather is different, at Illinois it's cold. Coach Davis and Coach [Ron] Zook, they have the same personalities. I like both and I like Coach [Tommy] Thigpen. Both [Davis and Zook] are player coaches. They can relate and they're always around the players."
After arriving in Chapel Hill Friday evening, Frierson was introduced to his host Bruce Carter.
"[Carter] is cool and we were also with Quan [Sturdivant]," Frierson said. "Both of them are cool. They're like brothers. If I come in, I can see myself fitting in with those guys. I was just having fun with them – just chilling."
Carter and Sturdivant, who are roommates, hung out with Frierson at their dorm and also showed him around the campus and Franklin Street.
"Everything was good, everything was grade A," Frierson said.
Frierson also sat down with Thigpen, his primary recruiter and UNC's linebacker coach.
"He was talking about how I could play all three linebacker positions," Frierson said. "He said he's looking at me for WILL [weakside], but he said with my body frame I could play all three.
"He was letting me know about the depth chart. He said the only person that could stop me from coming in and playing is me."
As a senior, Frierson played middle for Woodson recording 79 tackles including eight sacks, three interceptions, and three forced fumbles.
