Knox, a 6-foot-1, 231-pounder from Concord (N.C.), had been leaning towards UNC, whom he considered his "dream school," for a while now over offers from Louisville and Wake Forest.
"I feel like I'm part of the family down there [at UNC]," Knox said. "I feel like there's a great relationship with me and the coaches down there, especially my position coach, Coach Mo' [Allen Mogridge]. I love how they use the tight end – they were second in the nation in throwing to the tight end. And also, the degree they offer was key – they have one of the top business programs in the nation. And it's close by – if my family wants to come see me play, it's only an hour and a half away."
A verbal commitment from Justin Meredith, another tight end prospect, on Tuesday night forced Knox to seriously consider committing.
"One of the other tight ends had already committed, so there was only one scholarship left," Knox said. "I knew I was 100-percent to Carolina – I just wanted to explore my other options and enjoy the recruiting process. But I decided to make my decision now and be a Tar Heel. I didn't want to have the regret of having the chance to go to Carolina taken away."
Other than UNC, Knox now says he doesn't plan on visiting any other schools.
"My recruiting process is done," Knox said. "I'm going to visit UNC in the summer just to see my new home, but that's it."
After learning of Meredith's commitment on Wednesday afternoon, Knox, who had been discussing the possibility of committing with Mogridge for a while now, talked about the situation with his family.
"I talked to my uncle Charles about it," Knox said. "It was a pretty deep conversation that we had, but we came up with a conclusion and the conclusion is I'm a Tar Heel."
After making the decision, Knox contacted Mogridge and then spoke to Butch Davis.
"They were excited," Knox said. "It was a frenzy over there. Both of them were excited and they said I made a great choice and it's going to be a great opportunity for me and my family."
Mogridge also broken down how Knox and Meredith fit into UNC's plans.
"Coach Mo' kind of went in-depth on what he's going to have me doing," Knox said. "Mainly it's going to be me being the H-back and Justin Meredith probably being the ‘Y,' because of his size. He might have Justin Meredith doing some H-back, but mainly ‘Y.'
