Williams, a 6-foot-2 195-pound safety from Fayetteville (N.C.) Westover, worked out with defensive coordinator/secondary coach Chuck Pagano.
"I really enjoyed working with Coach Pagano and getting to know the rest of the coaching staff," said Williams. "He taught me some tips for playing man-defense."
Following the camp, Williams spoke to Thigpen to check on the status of his offer.
"[Sunday] he told me they were going to meet [Monday] about what happened at camp," said Williams. "I think there's a good possibility of me receiving [a UNC scholarship offer], but I don't want to jinx myself."
Williams has already collected scholarship offers form Duke, Virginia, and Wake Forest.
Back in May, Williams able to arrange an unofficial visit to North Carolina.
"Coach Thigpen invited me and my dad to come up there to stay up there in Chapel Hill," said Williams.
During their stay, Williams and his father explored various parts of Chapel Hill with Thigpen as their guide.
"We got to go around the campus a little bit, we got to go around Kenan Stadium and the building inside of it," said Williams. "He took us to the hotel where I'll be having an official visit at and we ate there. We had a good time."
At one point, Williams was favoring Wake Forest. However, he has since opened things up and UNC is very much in the mix.
"In my mind [UNC] is even with everybody else right now," said Williams. "I like the campus; I like the coaching staff – I like a lot about North Carolina."
In the beginning of his senior football season, Williams will establish a top five school listing. By the end of his football season, he said he's looking to make a verbal commitment.
This Saturday, Williams will attend Virginia Tech's camp. He also plans on camping at Clemson, Duke, South Carolina, and Wake Forest.
