The rising senior's name picked up steam at the LeBron James Skills Academy and carried over to the Nike Peach Jam, where he was one of the major standouts, and then continued throughout the rest of the month.
"I guess I just bounced back from the injury," Johnson said matter-of-factly.
Johnson, a 6-foot-9 power forward out of Cordova (S.C.) Edisto, said he's still working on his offense, but strives to get his hands on shots.
"I don't score much on offense, but I'll grab rebounds and put them back," Johnson said. "I have to work on it a little but I do block shots."
While Johnson didn't cite schools and said he didn't have an official list, it is known that South Carolina, Clemson, Florida, Connecticut and now North Carolina are recruiting him.
"It's crazy now," Johnson said. "Everybody is calling."
Johnson spoke with a North Carolina assistant on Tuesday and is expecting to hear from the Tar Heels head coach today.
"They were telling me that coach [Roy] Williams is going to call me today," Johnson said.
UNC watched Johnson throughout July -- at the LeBron James Skills Academy, Nike Peach Jam, AAU Super Showcase and at the Big Shots event in Rock Hill (S.C.) during the last few days of the evaluation period.
"It just started," he said of UNC's recruitment. "It's a good school, but I've got to look into it."
Johnson entered July ranked No. 81 overall in the 2012 class, but his reviews during the month included some high praise.
"He used his length and athleticism to impact things on defense, and also rebounding," wrote Scout.com's Brian Snow at the Peach Jam. "Then he used his soft touch to score around the rim and from the mid-range on offense. Johnson runs the floor extremely well, and overall just was very productive. Once he gets stronger, Johnson could turn into one of the better long term prospects coming out of this class.
"He was very impressive for the CP3 All-Stars during the event. He is long, athletic, and has a very nice touch in the mid-range. Also he blocks shots, and runs the floor very well. Now he does have to get stronger, but nearly every time out he was a force, and really put up big numbers."
