Yet Pinson's choice to join the Tar Heels wasn't a total surprise to Giles. After all, they attended UNC's game against Duke this past March together.
"Carolina is a great choice for him," Giles said. "He's a family type of guy ... he'll still be in-state so his parents can see him."
"I'll go see him, too."
Giles, who turned 15 last month, has been on UNC's campus twice. The aforementioned trip with Pinson wasn't his first. Giles attended the UNC-Virginia game the month before, and it was during that trip that Roy Williams offered him a scholarship - the earliest UNC's coach has ever offered a prospect.
Since then, no member of the Class of 2016 has been recruited harder nationwide. When Giles took the court early on a Saturday morning at the Hampton EYBL event three weeks ago, three head coaches were there waiting for him: Roy Williams, John Calipari and Mike Krzyzewski.
The affable Giles has been taking it all in stride so far, while observing how Pinson handled the process.
"He's humble - if you hang out with him you wouldn't think he's a big player like he is," Giles said of Pinson. "I look at him because he takes it smoothly and takes his time with it."
The two will team up again next season, attempting to repeat as NCISAA 3A state champions.
"I'm excited to have him -- it's fun because he's a great player, and a great leader on and off the court," Giles said.
Pinson is now beginning his role as a UNC recruiter, and Giles will be his top target. Giles admitted Pinson's presence in Chapel Hill will have some level of impact.
"(It'll play a role) a little bit because I played with him in high school and he's like a big brother to me," Giles admitted.
As the two posed for a photo together following Wednesday's announcement, Pinson took his UNC hat off and jokingly tried to place it on Giles's head.
"We're real close, that's like my little brother," Pinson said. "I'll be working on him."
