Williamson, a 6-foot-2, 220-pounder has primarily been used as an inside-the-box safety for Durham (N.C.) Jordan, until moving to linebacker fulltime during his senior year.
"I love tackling and I love being physical," Williamson said. "When I was real little, I played D-end before I moved to safety. In middle school and Pop Warner, I played D-end. I moved to safety my freshman year of high school. I'm really comfortable anywhere on the defense."
Since Signing Day, Williamson has kept in constant communication with UNC assistant coaches Dave Duggan and Vic Koenning.
"Actually, I just talked to Coach Vic after school [on Monday]," Williamson said. "We talk about plays. We talk about me getting up there and getting bigger and faster."
Williamson, who played his senior football season at 208 pounds, says he has currently reached the 220-225-pound range thanks in part to his work with a personal trainer.
"My trainer trains a lot of people – like college and NFL players," Williamson said. "When I say he gets at it, he gets at it. He's really the reason I got a scholarship."
With the help of his personal trainer, Williamson has finished the workout regimen UNC sends all of its signees.
"[UNC's workout] focused on different body parts each day," Williamson said. "It wasn't anything new that I hadn't done, but the way it focused on a set of muscles and not move around allowed me to get tired at the end of the workout."
In addition to consistently working out, Williamson has continued to play three sports for Jordan. Following the football season, he joined the basketball team, where he earned All-PAC 6 Conference honors and was named team MVP while playing forward. For the spring sports season, he was a part of the track team, throwing the shot put and running as a member of the 4x100 relay team.
Williamson's high school number, No. 7, is worn by UNC starting cornerback Tim Scott. As an alternative, Williamson has talked to Larry Fedora about sporting No. 17.
"I really like 17, because of my dad's birthday," Williamson said.
Having completed all the required paperwork and cleared UNC admissions as well as the NCAA Clearinghouse, Williamson is set to enroll in the second summer semester at UNC. He plans to major in the sports management or sports advertising fields.
Williamson, who has "hit it off" with each of UNC's signees that he has encountered, said he has discussed rooming together with just about every member of the Tar Heels' 2012 recruiting class. He has spoken the most prominently about rooming together with Clint Heaven. The two met during their UNC official visits in January.
