It was during the meeting that the Tar Heels' Hall of Fame coach offered Smith a scholarship.
"He basically said he is recruiting other guards in my class and he believes in playing two guards," Smith explained. "I think it would work out well, actually."
In addition to Smith, UNC has also offered class of 2016 guard Seventh Woods. Woods and Smith have a good friendship and played AAU together for two years with the Karolina Diamonds.
"I think it'd be deadly if you ask me," Smith said of him and Woods in the same backcourt. "Coach Williams said he wants me to come in and play right away."
"I'd definitely be comfortable playing with (Woods)," Smith continued. "He's a guy I like playing with and have played with on multiple occasions."
Over the last three months, Smith has added new offers from Kansas, Arizona, Florida and Duke to go along with initial ones he'd already received from VCU, N.C. State and Charlotte.
Though the UNC offer came after every school he said was waiting for except Kentucky, Smith won't hold it against the Tar Heels.
"It's definitely exciting to get an offer from them," he said. "It's one of the best schools in the country and its right down the street from me. I actually talked to him (Williams) about why the offer came so late. He said he's the last guy to offer usually, because he wants to meet the players face to face and doesn't offer over the phone. I don't mind that."
Smith said he's in no rush to narrow his list or make a collegiate decision. When he does make that decision, Woods could play a prominent role.
"We've definitely talked about playing together in college," said Smith. "On a scale of one to 10, I'd say the seriousness is about a seven."
Following the meeting with Williams and before leaving, Smith watched a scrimmage in the Smith Center that featured the current UNC team against a group of alumni.
"I think I could see myself fitting in well," he said. "It's a guard oriented offense they have, and they run a lot of isolation and ball screens for the guards."
After a whirlwind month that included trips to Italy and Las Vegas, Smith is taking a break from basketball until the first July open evaluation period. He'll continue to play with Team Loaded on the Adidas circuit.
