So if a school doesn't offer a scholarship, they have little to no shot of making the list?
"Yeah, that's how I see it," he said.
For now, Johnson said the list stands at five or six schools. All of which have made their serious interest known.
"Kentucky, North Carolina, Connecticut, Texas, Kansas and probably Arizona," Johnson listed.
For the 6-7, 220-pound forward, this week has been an educational experience. He excels in the paint, tallying points and rebounds around the hoop using his athleticism and assertive play. But at the NBPA Camp he's faced the challenge of talented seven-footers.
"I think this has prepared me for the next level as compared to every other event I'm going to be at," Johnson said.
On Thursday morning, 6-11 Stanford-bound big man Robin Lopez gave Johnson trouble, but despite a number or rejections, Johnson didn't quit and kept going strong at the bigger opponent.
And when not facing an elite center, he has put up big numbers, including a 27-point outing on the first night and several additional strong showings later in the week.
Considering his athleticism, muscle and super-active approach, he knows what he needs to develop to become dominant.
"Every day I'm constantly working on taking my post game outside, but until it's there for me I'll continue to play the post," Johnson said.
With an expanded perimeter game, Johnson can realize his goal of becoming more like the one-year UNC standout whose game he admires.
"I can be something like Marvin Williams – that's the type of player I [model my game] after."
