Each stop has presented unique challenges, tough competition and some of the best players in amateur basketball.
"It was tough," Smith said of his trip to Italy. "They play a whole different style of basketball than I think the pros do and college players. It was a great experience. It's not really a lot of isolation; it's more off-ball screens and getting shooters open. I've got to work on defending it better."
Added his father, Dennis Smith Sr.: "It's been a lot the last couple of weeks, it's a lot for anyone his age to handle. He's just trying to stay in shape so he can stay on the court."
At the NBPA Camp, Smith played more of a distributor role – the opposite of what he sometimes does with his Team Loaded AAU squad.
While his scoring numbers weren't high, he excelled hitting open teammates for easy transition baskets and weaving through traffic for layups. His ability to be both a facilitator and scoring point guard makes it possible for him to co-exist with other great players in any setting.
Smith played for two years on the AAU circuit with fellow 2016 UNC target Seventh Woods. The pair remains close and spent a good deal of time with each other at NBPA.
Roy Williams and the Tar Heels offered Woods this past October and asked Smith about his willingness to play with Woods in college.
"Seventh, me and him are like brothers off the court," Smith Jr. said. "He'll come to my house or I'll go down there."
"I know they can do it, they've done it before," explained Smith Sr. "They love to play with each other, but with both of them right now entertaining the point guard position, I'm not sure how that's going to work. That's another question that is yet still to be answered."
Williams called Smith on June 15, the first day college coaches could have unlimited contact with the rising junior class. Smith said he also spoke with Texas, Wake Forest, N.C. State, Duke, VCU and Florida State.
"I think the interest is pretty high from them right now," Smith Jr. said of UNC. "Coach Williams is going to come to my games, he did last year and he's going to do it again. I think the offer is coming up soon."
Woods plans to visit UNC on Monday and Smith told reporters there was a chance he would as well. His father explained, however, that his son won't be able to because of his commitment to the Kyrie Irving Camp.
Smith Jr. has mentioned visiting UNC on specific dates a few times in the last month, but hasn't yet made it to campus.
I'm going to take one to UNC sometime soon," Smith Jr. noted. "Coach (Roy) Williams called me on the 15th and talked to me for about 30 minutes. He wants me to take a visit sometime soon. I'm not sure when, though."
Smith Sr. added: "It's just a schedule thing. The schedule is what it is. Earlier in the month, Roy (Williams) had to do something with Nike and was busy. Then Junior's schedule was busy with travel and camps. We're trying to make it happen as soon as possible. We're in no way ducking or trying to miss Carolina, it's a must do thing. It's just that it has to fit the schedule for the school and for him."
