"It was definitely amazing for real," Williams said of the UNC head coach dropping by his school.
"All the students came to see them and tried to take pictures with them and get autographs," he added. "It was just humbling – and he's a very humble man. It was just amazing."
Williams said UNC, who already holds commitments from five-star prospects Isaiah Hicks and Nate Britt, has been keeping in touch as much as possible.
"They've been recruiting me well," Williams said of North Carolina's interest. "Coach Robinson has been keeping in touch with me. That would also be a good fit for me and they really teach discipline on the court."
During an early September visit to UNC, Williams said he enjoyed the tradition that UNC brings to the table.
"It was very historical," he said about Carolina. "It's definitely a tradition type of school. I can tell the players all get a long with each other. I met the coaches and I get a long with the coaches and I saw the campus. It's a nice campus."
Williams also pointed out the ever-present Carolina blue color around town.
"One of the weird things was when I went up there the fire trucks were baby blue," he said. "That was crazy. I'd never seen that before."
In general, Williams said he liked what North Carolina offers both on and off the court.
"It's very good school academic wise," Williams said. "On the court they are real good. I could see myself there."
As for the status of a possible Tar Heel scholarship offer?
"They said after they see my transcript they'll see what they are going to do," Williams said.
To go with the UNC, Williams said Villanova, Georgetown, Kentucky, Louisville, Miami, Florida, Texas, DePaul, Virginia Tech and Alabama are showing strong interest. He also mentioned he's hoping to visit a pair of Big East schools soon.
"Hopefully I make a trip out to Villanova and while I'm up there I'll see Georgetown's campus too," he said.
Through the first three games of his junior season, Williams, Scout.com's No. 8 overall prospect in the Class of 2013, is averaging just over 21 points a game and double figure rebounds.
