Accompanied by several family members, Knox, a 6-foot-1, 231-pound tight end from Concord (N.C.), arrived in Chapel Hill on Saturday morning.
"It was something that was highly anticipated by me and my family," Knox said. "We went up there and we had a great time. We didn't realize it was going to be that good."
Knox has visited UNC unofficially several times in the past, but his official trip marked the first time he was able to sit down and speak to Everett Withers one-on-one. Knox and Withers met in his office Sunday before the official trip concluded.
"We talked about how I liked the visit and how I'm getting ready to come to Carolina," Knox said. "We just had a real heart-to-heart conversation. We were talking about being prepared to attend UNC. He asked me what I thought of it and what I think of being there.
"I'm really looking forward to the college experience at North Carolina."
Additionally, the visit was the first time Knox was able to spend significant time with members of the football team.
"I got to see what the players were like person-to-person, up-close," Knox said. "I got to see how they work on the field and how they are off the field."
Among the players Knox spent the most time with was host Eric Ebron, a freshman tight end.
"Eric has probably the most upbeat personality," Knox said. "He has so much energy. He never sleeps – he's that type of guy. He was an awesome host. We had a great time. He showed me around – I saw the dorm rooms."
Most of Saturday was spent in Kenan Stadium watching UNC take on Miami.
"We had a great time at the game," Knox said. "The atmosphere was amazing. All the seats were filled up there. I liked how North Carolina came back and showed their pride and not just rolled over and let them beat them – they came back and let them make a game out of it. The one thing they told me was they didn't lose the game, they just ran out of time."
Following the game, Knox had dinner with coaches and then went out with the players.
On Sunday, Knox was given a full campus tour, including an in-depth look at the "Blue Zone," before meeting with his primary recruiter and UNC's tight ends coach Allen Mogridge.
"The main thing [we discussed] was my option to graduation early," Mogridge said. "And then he was going over different plays. He was showing me what they would do with me – he called it the ‘T.L. Tape' (Knox's nickname is T.L.). He's a visual teacher.
"Mainly, I'm going to be used as Jack Tabb this year – moving around at tight end to H-back – and Christian Wilson."
