Speaking at the Nike Global Challenge, Johnson said it was after Peach Jam a week ago that UNC first began to get involved.
"Basically they're looking for a perimeter player that can come in and score, like a shooter," Johnson said. "Another perimeter threat -- a shooter."
Johnson had not spoken to the UNC coaches before Peach Jam and he did not know they were planning on watching him while there. After Roy Williams and his assistant C.B. McGrath watched Johnson play at the Peach Jam, McGrath made contact.
"I've only talked to him a couple times," Johnson said of McGrath, "but I think he's a pretty good guy."
Johnson also provided his thoughts on UNC overall.
"It's a good school, a lot of history behind it, so that would be a good option to have," he said.
"I've seen them play and they get up and down, high, up-tempo offense. So I think it's a good style of play.
"(Roy Williams) is a good coach and has coached a lot of good players."
The Tar Heel staff watched Johnson multiple times this past week at the Nike Global Challenge. When it comes to what the next step is in North Carolina's recruitment of him, Johnson said simply, "Honestly I don't know."
Regarding his recruitment overall, Johnson listed offers from Marquette, Villanova, Indiana, Florida State, Miami, Wake Forest, and Alabama, amongst others.
In addition to North Carolina, Johnson said Syracuse is another school recruiting him that has yet to extend him a scholarship offer.
Virginia, Wake Forest and Villanova are the three schools Johnson said he has visited so far. He has no other visits planned and does not have a timetable for a commitment. Despite that, Johnson does know what he is looking for in a school.
"Just somewhere I would fit style of play-wise and go in and have an opportunity to play," Johnson said.
He went on to elaborate on just what style of play it is that he is hoping to find in his future school.
"Where they let their guards play," Johnson said, "ball screens, high-tempo offense, things like that."
There are a handful of schools he thinks are coming at him the hardest.
"I would probably say Alabama, Villanova, Florida State, Indiana, and Miami," Johnson said.
Johnson said he sees himself as a combo guard whose primary strength is his ability to score.
It's been a productive, albeit tiring month for Johnson, who has seen his stock rise as a result of his strong play.
"It's been fun. At the same time, I'm starting to kind of get exhausted a little bit," he said. "So, I'm just [going to] try to cut down my list and then make a decision as soon as I know what school is good for me."
It will be "probably after July" that Johnson trims down his list. He has yet to determine any schools in particular that will make the cut or just how many schools will be on that list.
