"After they offered me, my dad and I talked about it. I kind of already knew I was going to commit. So I called the coaches [on Thursday]. I talked to Coach [Butch] Davis about it. He told me he wanted me to come up there and hug him and that he can't wait for me to get down there and have fun."
Duke was the only other school thus far to offer Williamson, a 6-foot-2, 210-pound athlete from Durham (N.C.) Jordan. However, he was receiving significant interest from Clemson and Georgia.
"I loved the coaches, academics, and the people [at UNC]," Williamson said. "It's a good environment and I love the fan base."
Williamson is the second recruit coming out of Jordan to commit to the Tar Heels in as many years, following 2011 wide receiver signee T.J. Thorpe, who enrolled at UNC in January.
"I told T.J. [that I committed]," Williamson said. "He's glad that I committed to Carolina so that he has another former Jordan player there. It's great for me, because if I need help with anything when I'm there, I can just ask him about it."
Although Williamson has primarily played safety for Jordan, UNC is recruiting him as a linebacker.
"I'm okay with [playing linebacker]," Williamson said. "Right now, it's like I play linebacker now, so I should be good."
Around Thanksgiving of his sophomore season, Williamson moved to Durham from LaVergne, Tenn. because of his father's job. He is originally from Durham and lived in Tennessee for four years.
During his junior season, Williamson shared a secondary with Thorpe and totaled 127 tackles.
