Johnson had a big month of July and was highlighted by scouts as one of the month's top performers from the Class of 2012. UNC watched him at a number of events, including the LeBron James Skills Academy, Nike Peach Jam, AAU Super Showcase and at the Big Shots at Rock Hill event.
UNC assistant coach C.B. McGrath spoke with Johnson shortly after the conclusion of the second Evaluation Period and Roy Williams followed with the call on Tuesday evening.
"It's a good school, but I've got to look into it," Johnson said, noting that UNC just started seriously recruiting him.
The most significant development from the phone call with Williams was the delivery of a UNC scholarship offer, which Johnson confirmed.
The Tar Heels join Florida, UConn, Louisville and Ohio State, plus Clemson, South Carolina and NC State on Johnson's offered list.
The next step for Johnson is processing UNC's entry into his recruitment, as well as the other programs now aggressively in pursuit, and schedule visits.
"Yeah, I have to find time for one," Johnson said of a trip to Chapel Hill.
Johnson averaged 23 points, 12 rebounds and seven blocks per game as a junior at Edisto and was named the Gatorade South Carolina Player of the Year. He averaged 18 points, 15 rebounds and six blocks as a sophomore. Johnson also is the 2011 South Carolina state champion in the high jump.
"Johnson is a guy that can affect the game on the defensive end. He's long, athletic and has a knack for blocking shots. The Peach Jam was his coming out party and he did it in a big way. The college coaches took notice and he was among the top standouts of the evaluation period." -- Evan Daniels, Scout.com
"He used his length and athleticism to impact things on defense, and also rebounding. 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 (Peach Jam). 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." -- Brian Snow, Scout.com
